Lambing Frequency in the Ile de France, Suffolk and Babolna TETRA Stocks of Babolna c.o., Szendrő
29-32Views:685Lambing frequency of three different genotypes was evaluated in the breeding stock of Babolna c.o. Szendrő. Ile de France, Suffolk and Babolna TETRA breeding ewes gave the data for the further evaluation. The main aim of this research was to find out if there is any significant effect of selected parameters (registration class, lambing season, lambing type and the years) on the lambing frequency, the period between consecutive lambings. Production parameters of 9,471 Ile de France, 1,244 Suffolk and 7,618 Babolna TETRA ewes were collected and processed. The analysis covered the period between the years 1989-1999. It was concluded that not all of the evaluated parameters had a significant effect on lambing frequency. Not all of the genotypes showed significant differences, according to the examined parameters.

Study of the rams’ jumping order
59-62Views:596The bevahiour of Babolna Tetra, Ile de France and Suffolk rams was studied at semen collection by artificial vagina. The sequence of rams coming out of the group to the place of semen collection and the number of jumpings needed to ejaculation were observed. It was investigated if there were changes in these characters at different occasions, and did they show connection to the body condition. The number of jumpings before ejaculation was different in the different breeds. Semen was taken at the first jump from 63% of the Suffolk, 56% of the Babolna Tetra and 55% of the Ile de France rams. There was no early ejaculation at the Ile de France, but it was common among the Suffolk rams. The greatest changes in the jumping order between different semen collections were observed in the Babolna Tetra breed. There was a medium correlation in the Suffolk breed between the jumping order and body condition in the autumn and spring, which was tight and significant in winter.

Effect of genotype on the hematological parameter of TETRA-SL and Hungarian Partridge coloured chickens at young age
99-104Views:604Indigenous chickens are well known for their dual-purpose function and palatable meat. However, the information on their hematology parameters is lacking and hence hampering the poultry industry production of local breeds. The main objective of this study was to examine the hematological parameters of Hungarian Partridge Coloured hen (HPC) and TETRA-SL (TSL) genotype and determine the hematological reference interval values. This trial was part of the larger experiment where a total of 200 chicks (HPC + TSL) were reared. For this trial the blood samples were obtained from brachial wing veins of 8 chicks of each genotype for blood hematological analysis. The results indicated that some of the hematological parameters such as red blood cells-RBC, white blood cells-WBC, hemoglobin-Hb, hematocrit-Ht, platelets-Plt, lymphocytes-LYM, and granulocytes-GRAN were significantly affected by the genotypes (p < 0.05). The genotype did not affect the mean corpuscular volume-MCV, mean corpuscular hemoglobin-MCH, mean corpuscular hemoglobin concentration-MCHC, and GRAN (p > 0.05). The hematological reference interval values were slightly higher in the TSL genotype compared to HPC chicks. It is concluded that genotype has a significant effect on the hematological parameters. The results from this trial will be help and design the baseline reference values for the HPC genotype which will be useful in assessing the health status of these indigenous chickens.
