The objective of the study was to identify an association between the genotypes of BoLA-DRB3.2 loci (*16/- and *23/-) and occurrence of sub-clinical mastitis or latent mammary gland infections caused by different bacterial species in dairy cows. Blood was withdrawn from of 275 cows from two Polish dairy herds, and animals were genotyped for BoLA-DRB3.2*16 and BoLA-DRB3.2*23 using MPTPCR technique...
The aim of the current study was to examine the relation between the polymorphism of RBP4 (Retinol- -binding protein 4) genes and reproductive traits. The experimental material consisted of 367 sows of commercial line 990. The following traits were included in the study: total number born, number born alive, number of piglets at 21 days of age, number of weaned piglets, litter weight at 21 days of...
Genes of retinol-binding protein 4 (RBP4), epidermal growth factor (EGF) and prostaglandin-endoperoxide synthase 2 (PTGS2) were examined as candidate genes for reproductive traits in sows. The material included a total of 300 sows of the Polish Landrace (n=86), Polish Large White (n=64)and commercial Line 990 (n=150). Included in the study was the total number of piglets born (TNB),number of piglets...
In 53 F1 sows (Zlotnicka Spotted boars × Polish Large White sows) the insulin-like growth factor 1 (IGF1) and estrogen receptor (ESR) genes were assessed as candidate genes for total number of piglets born (TNB), number of piglets born alive (NBA), litter weight at birth (LWB), litter weight at weaning (LWW), number of piglets weaned (NPW), average piglet weight at weaning (AWW) and gestation length...
