Genetic Study of Dairy Cattle and Buffalo Bulls Based on Growth, Milk Production and Reproductive Traits
The present investigation aimed to conduct a genetic study of dairy cattle and buffalo bulls based on economic traits and their phenotypic correlation. The means of various economic traits in both the species are presented. Cattle bulls reported a better libido score, Flehmen response, requirement of mounting stimulus and semen volume, conception rate and expected predicted difference for milk ...

متن کاملGenetIc evaluatIon for mIlk productIon traIts In slovakIan lacaune sheep
Selection for breeding animals as parents of next generation, based on genetic analyses of most important traits, became a standard for selection practices in most of the farm animal species in Slovakia. In this respect, about ten years of experience could be traced in Slovakian dairy cattle (Candrák et al., 1997) and pigs (Groeneveld and Peškovičová, 1999 and Peškovičová et. al., 1999). First ...
متن کاملGenetic and Phenotypic Parameters for Milk Production Traits in the First and Second Lactation in Romanian Simmental Dairy Cows
The aim of the present study was to estimate genetic and phenotypic parameters of milk production traits in the first and second lactations of Romanian Simmental dairy cattle. For the estimation of variance, heritability, genetic and phenotypic correlations among milk yield, fat yield, protein yield, and percentages of fat and protein, 3400 first and second lactation records over a period of fi...
متن کاملAssociation between single-nucleotide polymorphisms and milk production traits in buffalo.
The aim of this study was to identify single-nucleotide polymorphisms (SNPs) in buffaloes associated with milk yield and content, in addition to somatic cell scores based on the cross-species transferability of SNPs from cattle to buffalo. A total of 15,745 SNPs were analyzed, of which 1562 showed 1% significance and 4742 with 5% significance, which were associated for all traits studied. After...
