Exploration of relations among the members of the supply chain on the basis of relationship indicators
177-190Views:130Today the various business units on the market are not competing individually against each other, but doing this as members of a supply chain, which are delivering the products or services to the customers with coordination. The participants are cooperating in the process of purchasing, production and sale. Their common objective is to deliver for the consumer demand. The supply chain approach of the enterprises is a business philosophy, which requires trust, commitment, coordination, shared objectives, support from the management, and the understanding and acceptance of the mutual dependence (Német, 2009). The main objective of our study is to analyse the relationships among the players of the supply chain through several relationship indicators, such as trust, economical satisfaction, social satisfaction, compelling power, non-compelling power, dependence, reputation and conflict. The relationship among the players of the supply chain has been analysed from two aspects, through the position and through the role of the players of the supply chain. This study aims to present the results of the analysis highlighting the critical points.

The study of the fertilizing effect of wheat straw ash in a greenhouse experiment
47-51Views:186The effect of wheat straw ash as a fertlizizer was studied in a pot experiment with an acidic sandy loam soil (pHKCl=4.9) with weak K and P supply. The test plant was ryegrass (Lolium perenne). The treatments were the following: 1. control untreated soil, 2. NPK fertilizer, 3. small dose of ash (1.4 g kg-1), 4 large dose of ash (2.8 g kg-1), 5. small dose ash completed with NP fertilizers. Soil parameters (pHH2O, pHKCl, ammoinum-lactate soluble P, K, 0.01 M CaCl2 soluble PO43--P, K, Mn, Cu, Zn ) and plant parameters (yield, P, K, Ca, Mg, Zn, Mn uptake) were investigated. Based on the analysis of the straw ash sample and the results of pot experiment it can be stated that the wheat straw ash is suitable for the fertilization of the studied soil. The small dose ash completed with NP resulted in the largest yield increment (43%). In order of the treatments the pHKCl changes to: 4.9, 4.8, 5.2, 5.8, 5.1. As the N : P2O5 : K2O ratio is 0 : 1: 3.5 in the wheat straw ash sample, to reach optimal yield ash should be completed with N and P.

Changes in the genetic variability of the Furioso-North Star population between 1989 and 2019
61-65Views:101The Furioso-North Star (FNS) is one of the indigenous Hungarian horse breeds, originated from Mezőhegyes Stud. The aim of this work was to analyze the pedigree diversity and inbreeding of the registered Hungarian Furioso-North Star population in two different time points: the first was the active population in 1989, the second was the active population in 2019. Pedigree data was analyzed using Endog 4.8 software. The pedigree completeness was calculated in three different ways. In the past 30 years the pedigrees became more complete. In the population 2019 were 5 horses with ancestor in the 40th generation. Only 17–17 animals covered the 50% of the genetic variability for the two population. The most important ancestor was Herod xx in both reference populations. The FNS breed has English Thoroughbred background, that might be the reason of having several horses form this breed in the database. There were six animals among the ten most important ancestors in both reference populations. The average inbreeding coefficient was 3.31 in 1989 and 4.22 in 2019. Animals with highest inbreeding coefficient were born from the mating of close relatives (typically father-daughter). The Bart Furioso III-84 Boglár had the highest inbreeding coefficient (0.299) in the population 2019.

Changes in the Sulphur Content of Winter Wheat in a Field Experiment
85-88Views:79The use of superphosphate as P-containing fertiliser decreased in the last years in many countries in accordance with strict air pollution laws, and the S-deposition decreased from the atmosphere to the soil as well.
Winter wheat is the one of the S-demanding plants. Recently, the gradually increasing S absence endanger the formation of required average yield of winter wheat, and has bad effect on its quality.
We examined the effect of treatments on the sulphur-, nitrogen content and the N/S ratio of winter wheat in the whole upperground plant and in the grain and straw at harvest in a arable land sulphur fertilization experiment on brown forest soil (Agricultural Company of Felsőzsolca).
We analysed the samples from spring to harvesting, in the critical phenophases. In this study we discuss only the values from the stooling and stalking and the results of analysis of grain and straw in the harvest.
We experienced that the concentration of sulphur in the whole upperground parts of winter wheat showed increase to the end of vegetation independently of fertilization. The N/S ratio was between 8% and 12% in the beginning of the growth period in the whole upperground plant, while the ratio in the grain at harvest was between 13 and 14%. When we examined the whole upperground plant, stalk and leaf at stalking, we got the highest sulphur content in the leaf. Mostly the middle level sulphur fertilization dose (4 l/ha) increased the sulphur accumulation in the green plant. At total maturing, the greatest part of accumulated sulphur is in the grain, but then the effect of fertilization is less glaring. -
The correlation of foreign language proficiency, employment and regional competitiveness in the North Great Plain Region of Hungary
74-82Views:61Employment is one of the basic factors when evaluating a region’s competitiveness. Boosting employment figures will also increase individual income. However, the creation of jobs alone will not solve the problems of unemployment, as labour force with skills matched to labour market demands should also be available. Continuous development of the labour force, adjusted to recent needs in the labour market, can contribute to a region’s competitiveness. Mismatches between education and labour market requirements would be too expensive, especially for backward regions like the North Great Plain Region of Hungary. Foreign language education should also be adapted to the changing economy when selecting target languages and language skills. A workforce equipped with contemporary and needed second language skills can be an element in making a region attractive for investors. Although current trends show signs of improvement, Hungary and especially the North Great Plain Region still does not have much to offer in this respect. The paper examines the reasons for the low level of second language acquisition among Hungarians and the population of the North Great Plain Region and explores the ways foreign language knowledge could promote economic development.

Psychoactive substance the examination of implements and school factors among young persons living on country
11-17Views:75The study investigates the drug addiction, school problems and the underlying emotional disorders of provincial young people. I assumed that school problems are connected with the
youth’s legal and illegal drug consumption.
In my research, I used the Euroadad questionnaire taken at the Drug Ambulance of Nyíregyháza. The sample covered 144 interviewees, 76.9% of whom were „diverted” from jurisdiction. The other respondents volunteered for the therapy.
The linear regression analysis was applied to examine the interrelations between the elements under study.
All of the 144 respondents have tried or regularly apply some consciousness-modifying substance. Most of them are young adults. The preferred drugs were marijuana and ecstasy. All
consume alcohol as well. A significant connection can be proved between the majority of the psychological and school behavioural problems under survey and the drug abuse. The more problematic group covers those taking extasy. -
Analysis of longevity in Holstein Friesian cattle using proteomic approaches
21-25Views:184The aim of the present study was to determine marker proteins those are associated with functional longevity of dairy cattle. Holstein-Friesian cows were grouped based on their performance as follows: group 1) individuals with good longevity traits; group 2) short production life because of poor reproduction traits; group 3) short production life with low milk yield. Twelve individuals were sampled in each group, blood and milk samples were collected from cows. Blood samples were analysed with two dimensional polyacrylamide gel electrophoresis (2D PAGE), MALDI TOF/TOF and nanoLCMS/MS. The milk samples were analysed with MALDI TOF/TOF and nanoLC-MS/MS. Using the optimized gel based proteomic approach,
we have succesfully separated 143 proteins in the group1, 139 proteins in the group2 and 136 proteins in the group3, but we could not find significant differences between groups in the expression pattern. Using MALDI TOF/TOF and nanoLC-IonTrap MS, we have found eleven protein sequences those were expressed only in the samples of good longevity group. -
Examination of the impact of sowing technology models on the ear, constiuent and yield parameters of the yield formation elements of maize hybrids of different genotypes
17-23Views:112Production year 2012 has been characterised by climatic extremities. The weather of this year can be considered very contradictory in terms of maize production. The droughty conditions of the winter and spring months had a negative effect on both germination and starting vigour. The favourable weather of May-July created ideal conditions for intensive growth and generative processes; however the lack of precipitation in August and September had a damaging effect on the development of yield composing elements and grain saturation processes as well. Under such circumstances, the sowing date models caused significant differences in the yield and quality of the hybrids belonging to different growth periods. The growing period of the maize hybrids has been shortened as a result of the unfavourable climatic conditions.
Based on the trial results, it is verifiable that short growing period hybrids can be securely sown in draughty years even with a later sowing date, however using a later sowing date in the case of longer growth period hybrids may result even in a yield loss of 2–3 t ha-1. In the case of early and average sowing dates, with given yearly conditions the hybrids of the observed FAO 370-390 hybrid group provided the best result (12.40 t ha-1, 10.99 t ha-1), while in the case of the third, late sowing date the yield dominance of the FAO 290-350 hybrid group is the most significant (10.08 t ha-1).
The analysis of the yield composing elements found that the P9578 hybrid has the highest shelling ratio, while its cob is the shortest. The P9494 hybrid has a high yield and the highest thousand grain weight, while the DKC 4983 has the longest cob and its thousand grain weight is above 300 g.
The results confirm the fact that DKC 4590 has the highest yield potential and starch content, while in terms of oil and protein content the Szegedi 386 and NK Octet hybrids are the most important.

Effects of soil compost application on the leaf surface area per running meter of apple (Malus domesticaBorkh.) leaves cultivated in organic and integrated orchard
111-116Views:142The effect of different compost doses on the nutrient contents of the soil (in depth of 0–30) were measured in an (organic and integrated) apple orchards. The leaf surface area per running meter shoot for certain apple species (Golden Delicious and Pinova) were determined.
The field experiments were conducted in the Research Field of Debrecen-Pallag, University of Debrecen, the analysis of the soil and plant samples took place in the laboratories of the Institute of Agricultural Chemistry and Soil Science.
The compost treatments increased the amount of the examined nutrients in the top 30 cm of soil originated from organic and integrated orchard. Changes in rainfall were observed in the trends of the leaf surface area of the two apple varieties. 2010 was rainy and 2012 was drier. The leaf surface area of the Pinova increased better under the precipitation/year effect, than in case of the nutrient supply treatments. The opposite was observed in case of the Golden Delicious. -
The examination of the marigold’s (Calendula officinalis L.) nutrient requirement in small-plot trial
61-66Views:153During our research we investigated the marigold's (Calendula officinalis L.) nutrient requirements with different fertilization treatments in small-plot trial. We measured the harvested marigold's drug's raw and dry weight on a weekly basis from July 6th until August 17th. We were using SPME (Solid phase microextraction) and GC-MS (gas chromatograph-mass spectrometer) to examined the effects of the different fertilization settings for the herb's main active ingredients of essential oil's percentage.
It was concluded, based on the results, the N30P40K60 fertilization setting is ideal in terms of the quantity of the marigold drug. Both the raw and the dry weights' measurements of the case, this fertilization setting have the most important effect on the herb's yield. The analysis of variance didn't show significant differences between the plots with different fertilization settings. We discovered relationship between the drying loss and the increasing quantities of nutrients. We think it may be possible the Alpha-thujon's and Alpha-cadinol's production and the drying loss's data are connected, which appear to confirm the N15P20K30 treatment's data.

Az évszak és az azonos évszakban történt ismételt mintavételek hatása holstein tenyészbikák ejakulátumának minőségi- és mennyiségi jellemzőire
33-37Views:84This study was carried out at the Hungarian National Artificial Insemination Centre in order to evaluate the seasonal effects on the quantitative and qualitative parameters of sperm production using sperm analyser equipment. The volume of ejaculate (VE), percentage of living sperm (PLS), spermatozoa concentration (SC), motility score (MC), percentage of motile spermatozoa (PMS), speed of movement of sperm cells (SMS) and the percentage of sperm cells moving straightforward (PSMS) were collected and observed in three seasons (summer, autumn, winter) in Holstein-Friesian breeding bulls (n = 15). The sperm collection was done for three successive weeks in every season on the same day (summer: n = 41, autumn: n=39, winter: n = 42, altogether: n = 122). The same sperm samples were measured by sperm analyser equipment (HTM version 7.0, Danvers) for PMS, SMS and PSMS. The seasonal and the number of sperm collection effects were confirmed on semen characteristics by multiple analysis of variance (two ways MANOVA, Type III) using the program package of STATISTICA 4.5. The average values of VE were similar in the three seasons (summer: from 4.42 to 6.28 cm3, autumn: from 4.08 to 6.86 cm3, winter: from 5.43 to 5.71 cm3). The average values of the MC were similar in each of the three seasons (summer: from 3.66-4.00 M; autumn: from 3.66-3.77 M; winter: from 3.86-4.07 M). The summary of all effects for season (P<0.001), repeated sperm collections in the same season (P<0.05) and interaction of two traits (P<0.01) were established on the measured characteristics. The special effects (P<0.05) of a given season were calculated, excepting the VE and MC, on all of the measured characteristics. The special effect (P<0.01) of the repeated sperm collections in the same season was verified in only one case (SMS). It is not surprised at the interaction was established on the VE (P<0.001), PMS (P<0.05), and SMS (P<10.0). The results of present study suggest that seasonal effect on sperm quality of breeding bulls cannot be eliminated even at standard feeding and keeping conditions. Considering our results, we can recommend that the average values of three successive weeks in every season be used, to take advantage of seasonal effect on the quantitative and qualitative parameters of sperm production.

Sequence heterogeneity of nSSR and cpDNA loci of Cucurbits (Citrullus sp.)
125-134Views:95The evolution of water melon (Citrullus lanatus) microsatellites from the 15th century (Debrecen); 13th (Buda); and 18th century, (Pannonhalma) were analyzed. Microsatellite (nSSR, nuclear simple sequence repeat) and cpDNA profiles of the aDNA (ancient DNA) of seed remains were compared to modern water melon cultivars and landraces. Sixteen primer pairs were applied. Sequence analysis at the (CT)26 and cpDNA trnV loci revealed a (CT)3 and Adenin deletions, respectively, form the current water melon cultivar compared to the medieval sample. Cila-1), a new LTR retrotansposon has been described. For morphological reconstruction, a dendrogram produced by SPSS11 based on the presence versus absence of 24 phenotypic characters were also analyzed.

Effect of the storage temperature onto the quality of the semen of rams of different breeds
75-79Views:141Semen of 10 Tsigai,3 Prolific Merino and 7 Barbados Blackbelly rams was taken in January, out of the season. Split samples of the diluted semen samples were kept at 23, v.s. 8oC and their motilitywas evaluated daily for 3 days by subjective microscopic investigation. The ratio of motile spermatozoa was strongly decreased during the first day, later the motility rate was sinking more slowly. It could be stated by multivariance analysis that the motility value of diluted semen of Prolific Merino rams was higher and showed a slower reduction as compared to the other two breeds. The decrease of the motility rates was slower at 8oC than at 23oC.

Addictions of youngsters living in the countryside: social and demographic background of alcohol consumption
81-84Views:132In the past 10–15 years, the consumption of illegal drugs has increased significantly both in Hungary and in our county. In parallel with the society’s getting more and more open, the fulfilment of personal freedom, and the spreading of globalisation and individual culture, the use of drugs has become more and more accessible and acceptable to the young.
Social problems are supposedly connected with the interviewees’ alcohol consumption. The EuroADAD questionnaire was used. The sample covered 190 interviewees. I have processed the data with the SPSS statistical program package.
The linear regression analysis was applied to examine the interrelations between the elements under study. Almost consume alcohol as well. Among the examined socio-demographic variables, youth alcohol consumption was most affected by the gender of the respondent, the dissatisfaction with living conditions, and the change of residence.

The effect of gossypol acetate on the fertility of boars
47-55Views:148This study evaluated the effect of gossypol acetate, a potential antifertility compound, on semen quality and testicular histopathology of boars. Six boars were allotted into two experimental groups. Half of the animals were fed a diet that was supplemented with 2 mg of gossypol acetate per kg body weight per day for 9 weeks, control animals received a gossypol acetate-free feed. During the experimental period, semen was collected weekly from each boar and semen parameters were recorded. The animals were then euthanized, testicular samples were collected and histopathological examination of the testicular cells, as well as morphometrical analysis of the seminiferous tubules, were performed. The percentage of spermatozoa showing tail abnormalities increased significantly (P=0.017) in the semen of boars fed gossypol acetate-supplemented feed, while several other semen parameters deteriorated without showing statistical significance. Gossypol acetate supplementation also led to a decrease (P=0.042) in the number of spermatogonia in the seminiferous tubules and an increase (P=0.020) in the number of vacuoles in the seminiferous epithelium, consistent with changes seen in cases of male reproductive toxicity. In conclusion, gossypol acetate negatively affected a number of semen characteristics and also had detrimental effects on the histopathology of the testes.

The Effect of Tillage Treatments on Soil Temperature at Planting and on Corn (Zea mays L.) Yield
40-44Views:113The effect of soil temperature was evaluated on the yield of the Occitan corn hybrid at a depth of 5 cm. We examined this effect on the time required from planting to emergence for three average durations: five, ten and fifteen days, all calculated from the day of planting. Winter plowing (27 cm), spring plowing (23 cm), disc-till (12 cm) treatments and 120 kg N per hectare fertilizer were applied. As a result of our analysis, we determined the post planting optimum soil temperatures for various time periods. The average soil temperature for a time period of 15 days post planting is the most usable for determining actual yields, followed by ten days, with five days proved to be the least usable (winter plow R2 = 0.86, spring plow R2 = 0.87, disc-till R2 = 0.64).

Analyzing the Competitiveness of Balmazujvaros on the Basis of a SWOT-Analysis, Emphasizing Tourism
262-271Views:106My study examined the competitiveness of Balmazujvaros, in regard to tourism. The town is situated in the Northern Great Plain region, in Hajdu-Bihar county, 22 km from Debrecen, together with Egyek, Hortobagy and Tiszacsege joined the statistical subregion of Balmazujvaros. Comparing with the neighbouring settlements, it has similar geographical features and posesses thermal water that was determined to be medicinal, which is a feature of the region. Balmazujvaros as a typical country town as it has a dominant agricultural character. It gained town status in 1989. Part of the town is situated in the National Park of Hortobagy.
The first part of my study is to determine the number of rival settlements from the viewpoint of tourism. I will analyze the results of a questionnaire given to tourists in Balmazujvaros between June 15 August 31 2003, and introduce the primary results. The SWOT analysis will show the primary and secondary information and the examination of the results.
If we take into account the strengths, weaknesses, opportunities and threats of this town, we can make the following conclusion: tourism is an opportunity with a well-developed infrastructure, a third sector, subsidies and improved local interest. A sound and well-defined marketing strategy is essential for Balmazujvaros, in order to overwhelm its strong rivals -
Effect of weather conditions on the protein content and baking value of winter wheat flour
83-94Views:131We searched for connections between weather conditions (with its sub-parameters as precipitation and average temperature) and the yearly formation of two quality parameters (protein content and baking value) on three levels of mineral fertilization, based on the results of a variety comparison experiment on chernozem soil, to select those weather parameters and critical periods which have significant effects on the quality of winter wheat flour.
We established that the protein content of winter wheat flour can be increased with increasing levels of mineral fertilizers. Protein content is lower and has higher deviation during non-fertilized conditions in different cropping years than on higher fertilization levels. Thus, it seems proved again that quality (as protein content) is mainly formed by the crop year, but can be improved with adequate agricultural engineering (with mineral fertilization in the present case). The higher sum of precipitation in May, and the lower average temperature after flowering, have the highest increasing effect on the protein content of flour of the examined parameters. Based on the results of the examined period, the rainier and warmer term than average before flowering and lower – average amount of precipitation and colder circumstances are favourable for higher baking values. The analysis with data of decades, proves the importance of the first half of May and the middle of June as especially important periods for quality formation. An increasing nutrient supply has different effects on the varieties; mineral fertilization increased the baking value of GK Öthalom winter wheat variety in almost every case, but the second level of fertilization decreased it in half of the examined years. Additionally, mineral fertilization played a role in the stabilization of the quality of highlighted varieties. -
Comparative analysis of the transformation of Hungarian and East German agriculture
164-170Views:79Agriculture, and within it, the development and later transformation of the cooperative system shows many similarities between Hungary and the Eastern German provinces. A few examples can be mentioned, such as the mistrust against the notion of cooperation, the forced development of the cooperatives and, as an occupied territory, the influence of the Soviet Union. Similar issues emerged in both countries’ agriculture and the measures taken were also alike. Similar social, economic processes and changes were started at the end of the 1980s (1989/90) and these had a significant effect on the areas that serve as a basis for this study.

Analysis of the main parameters of spring and summer food compound of roe deer (Capreolus capreolus L.) on the two hunting grounds of the Alföld plain
7-10Views:103It is widespread that roe deer are very choosy. It needs this sorting because the micro organisms, which help the digestion of high fibre plants, are missing in its stomach that is why they are mostly called „concentrate selectors” (Hoffmann, 1985, 1988, 1989).
These animals should mostly eat easily digestible plants with high nutrition level (pulses, buds, sprouts and flowers), and they are able to do this sorting because of their small mouth size. In winter there is a lack of these plants, so the high selectivity occurs only when the feed is in abundance.
Examining the amount and quality of vegetation available on the habitat of roe deer we can identify the species which can satisfy their feed demand. It is known, that roe deer as other large ruminants, from the plant abundance prefer certain plants and plant parts while there are others which are avoided. The identification of the eaten species and the rate of their occurrence in the feed is the first step to become acquainted with the
interaction between animal and the surroundings. -
The Bereg flooding in 2001 – Impacts on the built environment
99-106Views:112Today, an increasing number of natural disaster events are witnessed. Our respond to these disasters is increasingly important and more timely problem. Before PhD studies my research aimed at revealing the impacts reconstruction, restoration and damage prevention had on the environmental, social and economic segments of disaster-hit areas. This present paper intends to provide preliminary results of the work already carried out in the Bereg Region, where I specialized on the effects of Tisza flood.This paper focuses on the results and conclusions drawn from the analysis of environmental consequences resultant from the flood based on a study area.

Identification of Hucul mare families by mtDNA markers
75-79Views:177Hundred animal species have disappeared during the last century. By this time, approximately one-third of domestic animals have been in the endangered category. Hucul horses are also in this category; furthermore saving the genetic diversity beside the race preservation is an important challenge as well. The number of mares and stallions is only one of the expressive elements of genetic diversity; together with their quality determine the genetic variability of this breed. Beyond that, if an exact breed can originates from more founders, it can be more renewed genetically. Stud book documents these data by registering the mare families and stallions’ genealogical lineage. Molecular genetics, especially mitochondrial DNA analysis can make the precise identification of mare families possible. As a result of these molecular based methods, protection of genetic diversity, as well as breed preservation became more reliable. After the primer designing, the optimal primer pair was chosen which targets a 1092 bp length DNA sequence in the cytochrome b region. After the successful PCR optimalisation, we determined 170 Hucul mares’ sequences. According to our results, the samples compose ten haplotypes, which are much less, than the registered number of mare families in the stud book. Further investigations are needed to reach more representative results, and drawn the further consequences.

Comparative analysis of certain soil microbiological characteristics of the carbon cycle
137-141Views:138In our researches, we examine the soil microbial parameters related to the carbon cycle. In this study, we compare the changes of microbial biomass carbon (MBC) and the soil CO2 production in soil samples which were taken in spring and autumn. The 30 years old long-term experiment of Debrecen-Látókép is continued in our experiments. The long-term fertilization experiment was set in 1983, and our sample was taken in spring 2014. The examinations of soil respiration processes and factors that influence soil respiration are required in optimal management. In our study, we interested to know how the growing levels of fertilization influence the soil respiration and microbial biomass carbon under non-irrigated and irrigated conditions in maize mono, bi, and triculture.

Examination of Reproductive Performance of Roe Deer (Capreolus capreolus) in Hungary
33-38Views:101The objective of the research partly is to compare the reproduction performance of the populations living in different regions with regard to some special characteristics (age, condition).
When estimating the age through tooth wear and cementum-layer-counting there was a difference of 0.87 years in favour of the first one (r=0,840; p<0,001). I found cementum layers at 42% of the does in the study after examining the MI teeth.
There was lose connection between the weight (eviscerated, with head and legs) and the KFI (r=0,296; p<0,01), and for further analysis, I used only the KFI as the index for condition.
The regional average KFI varied from 0.24-0.37 in fawns, 0.82-1.73 in does, with individual extremes of 0-4.05. Within the examined regions the highest index belonged to the prime-aged does, while the 1-year-olds had a lower rate, and it was the lowest in the does older than 8 years.
The rate of fertility was between 83,3(ns)-100% as we can see from the presence of the CL. All the examined does were fertile, except in one region, while among the female fawns in two regions I only found three with active ovaries. The average number of CL was 1.5-2.13, and this varied by regions; all in all it was the highest in the 2-7-year-old group (1.96) and in the ones over 8 years (2.00!), while it was lower in the does younger than 1 year (1.90). The high fertility of the does over 8 years is remarkable.
I could examine the number of embryos in two regions during the post-implantation period, and beside 100% fertility I found significant differences among the does, which can be associated with the condition. The ratio of CL carriers and the pregnant does was 100% and 73% in the two regions, the average number of CL were 1.92 and 1.72, while the average embryo number were 1.83 and 1.36 per doe. The difference between the CL and the embryo numbers on the two regions were 5% and 21%. The difference (prenatal loss) is in connection with the age (age class) of the doe. It is possible, however, that in some cases oestrus was not followed by gestation. But in roe deer, owing to the commonly known lack of luteolysis-mechanism (Flint et al., 1994), the regression of the CL of the does that did not get pregnant takes place in December and January, so the CL found in January cannot prove a previous pregnancy, which might have been followed by an abortion.
Although it has to be proven, it seems that the number of the CL (potential progeny) can be associated with the age (r=0,418; p<0,01) and the weight (r=0,312; p<0,01) of the doe, while the embryo number (realised progeny) is influenced by the age of the doe and probably by external factors.
It is essential to continue and extend the research to increase the reliability of the results and their correlation.
