Livestock production development in AP Vojvodina
501-513Views:83The aim of this paper is to present the effects of breeding program implementation on the development of animal breeding in Vojvodina since 2010. Data from the Main breeding organization (controlled population) and data from the Statistical Office of the Republic of Serbia (total population) were used as a basis for this research. The main breeding organization is the Departmant of
Animal Science, Faculty of Agriculture, University of Novi Sad that implemented the main breeding programs in cattle, pig, sheep, goat, horse and poultry production. The milk yield in a recorded population of Holstein Friesian and Simmental cows shows evident phenotypic increasing trend as opposed to a population that is not controlled. The results of the selection measures in Vojvodina show that pig breeding has an upward trend and that we have an increasing number of small and medium (family) farms. Interest in sheep and goat production is increasing primarily because of the high demand for products made from sheep meat and goat milk and meat. In the recent decades, Vojvodina has been faced with a decrease in the number of horses. At the same time, there is an increasing interest in sports horses and recreation. According to poultry production results of parental flocks, an increasing tendency was observed in the production of controlled flocks recently, while the number of breeding stock breeders was reduced. -
The analysis of the milk production and the body condition on two Saanen goat-farms
53-59Views:129The authors carried out an examination on two Saanen goat farms during four months from May to August 2008. The body condition score and milk production of the goats were measured. In data processing analysis of variance was used to compare the data of the studied farms. They tried to find the answer for the question how the body condition scores and milk production change in each month. The changes observed in each farm were examined separately then they compared the values of the two farms.. On one of the farms the nutrition was proper therefore with an ideal, intermediate body condition (average 2.73) the goats produced a good amount of milk (2.5 milk-kg/mother/day). On the other farm the nutrition was not proper, therefore the body condition of the goats was weak (average 1.88). Their milk production decreased significantly from month to month (average 2.35 milk-kg/mother/day). The authors could conclude considering both farms that the more milk the goats produced, the lower their body condition score became. The two parameters showed negative correlation.

The milk production and prolification of Saanen goats of various body condition and ages
49-52Views:110In our experiments we tried to find correlation between the age and the body condition of milking goats. We found that these factors significantly incluence the economic parameters of the goats; they have effect on their milk production and reproduction as well. Body condition is the lowest in case of the 3-5-year-old goats, whereas it is the highest in case of the 1-2-year-old. The highest number of kids (2.5) are produced by the 3-5-year-old, while the 1-2-year-old have the fewest kids. Lactation milk production is the highest in case of the 4-5-year-old animals, the lowest in the 1-2-year-old. The lactation period is the longest in case of the 3-4-year old animals in contrast to the younger. The difference is significant in each experiment.

Assessment of energy generated by biogas production in the educational industrial unit of the University of Szeged, Faculty of Agriculture, with special regard to biomass originating from agriculture and the food industry
137-140Views:103The importance of waste treatment is increasing. Environmental aims are the main driving force. Stricter regulations for landfills lead to the development of alternative treatment methods for waste. For agro-mechanical research, wastes from animal rearing and the food industry, secondary-tertiary biomass, is of deep concern. Available technology is versatile and relatively simple to use as a reliable and effective means of producing a gaseous fuel from various organic waste. The most common application has been the digestion of animal dung, agricultural, and food-industrial waste. This was studied by our department in our pilot farm of our Faculty. The 50-dairy cow, family sized model farm was built in the summer of 1991, as a result of a Dutch – Hungarian cooperation, on the property of the Faculty. The new pig farm, with 30 sows, and the new goat farm, with 100 nannies, was given to the Faculty on 25 April 2001. On the basis of livestock data, the annual dung production and the producible energy were determinate. The energy was calculated by biogas production coefficients in literature.

Strategic Steps in the Sheep and Goat Branches
61-68Views:146The balance of the sheep and goat branches can be summarised as follows:
If the increase in stock size, specific yields, genetic improvement and modernisation are not realised, several thousand shepherds will lose their jobs and possibilities to work, and their families will lose their only source of livelihood.
Several hundred hectares of grassland will become weedy and the costs of crop protection will increase in these regions. Pollen pollution, the number of allergic ailments and medical costs will increase, mentioning only the main disadvantages. Its financial requirement is nearly equal to the one required for development without any essential compensation or production.
In order to develop a competitive branch, a subsidisation of 10-20 billion HUF is needed until the accession of Hungary to the EU, depending on the scale and progressivity of development. The subsidisation and realisation of the strategic steps would result in:
– the establishment of a registered livestock with 1.5 million ewes, which would ensure better market position for the branch in the EU (5%),
– the establishment of a competitive and marketable branch with a production value of 15-25 billion HUF, calculated using the present price level (after accession, the branch would be self-operating and profitable, with the 6-8 billion HUF/year normative subsidisation by the EU),
– the establishment of a genetic potential which would ensure our participation in profitable international breeding animal market, which provides extra profit,
– the establishment of a sheep husbandry with better genetic potential and phenotypic performance, producing a quality of international level,
– the maintenance of the workplace of more than 10.000 people (saving 3-5 billion HUF/year of the budget),
– the maintenance of the condition of growing areas of grasslands with their advantages (crop protection and public health) whose financial effect is considerable. -
A review on the trend of livestock breeds in Laos
227-237Views:421When the livestock sector is considered an essential role in farmers' livelihood, and local breeds are still the critical component of animal breeding in Laos. Thus, there is a need to review the previous, current situation and prospects for Laos' livestock production. It aimed to study the different traits among the existing dominant local and improved livestock breeds (cattle, pig, and goat) and a more in-depth study on the livestock sector's previous evolving and prospects. Our findings revealed that the general trend of livestock population in Laos increased year-by-year for over 45 years, except for 1995 to 2000. It was decreased by almost 22% due to the new national strategy on economic revolution. The first foreign breeds were introduced into Laos, i.e., Large White, Landrace, and Duroc in 1980, Red Sindhi bulls in 1998, the frozen semen of Red Brahman 2003, and Bach Thao goats between 2001 to 2003. Unfortunately, many data are still not precise for introducing other foreign breeds like Boer goats, Thai Grey and Red Brahman. There were many missing data on the improvement of livestock breeds in Laos, including the local and improved breeds' reproductive and productive performance, which needs more study and research. We conclude that the semi-complex farm operation should be applied to improve livestock breeding and their productions in Laos.

Bacteria in the milk of sheep with or without mastitis- mini Review
47-52Views:373From a nutritional point of view, sheep milk is more valuable than cow and goat milk and the interest for sheep milk is increasing in many countries. However, sheep milk is easily contaminated during milking, handling, and transport and it is an ideal medium for bacterial propagation. Consequently, sheep milk spoils quite quickly. The proper, clean handling of milk is not only of sanitarian interest, but it also serves the farmers’ interests, because contaminated milk may not be distributed, and is unsuitable for producing good quality products. Following this technological trend, this review addresses the bacterial composition of sheep milk with and without mastitis. Even though sheep milk contains a lot of bacteria, this review article highlighted total plate count, Enterobacteriaceae, coliform, Staphylococcus aureus, Escherichia coli, Listeria monocytogenes, Campylobacter, Salmonella spp. and Streptococcus spp. Mastitis in sheep is a vital cause of mortality, reduction in milk production and early culling. The reported risk factors for mastitis in sheep were age, a case of mastitis, breed, husbandry systems, and location. The main priority should be implementation of programs to minimize human pathogenic bacteria and mastitis in raw ewe milk.
