Current studies on the prion protein (PRNP) gene polymorphism focus primarily on the causative mutations that influence BSE susceptibility in cattle. The specific genetic structure determined by the i...
The objective of the study was to investigate the effects of supplementing different plant oils to the basal diet on milk yield and milk composition in mid-lactating dairy cows. Forty Chinese Holstein...
The objective of this study was to verify the hypothesis postulating the location of QTL linked marker for milk performance traits in the proximal section of chromosome BTA1 by analyzing the microsate...
An experiment was conducted to evaluate the effect of ruminally protected methionine (Mepron? Degussa AG, Germany) in dairy cows. Three weeks before calving 36 cows (Holstein and Czech Fleckvieh breed...
The exclusive pre-selective effect of BLAD carriers reproducing in the exposed Holstein-Friesian cattle population prompted to search for the candidate gene variants of high quality of milk performanc...
Single nucleotide polymorphisms (SNPs), which are present in the encoding part of the genes responsible for important breeding functions, exert an influence on the cattle’s phenotype since their funct...
The undertaken study aimed at determining relations between kappa-casein polymorphism and milk performance traits in population of 304 Holstein-Friesian heifer cows bred in fi ve herds in the Kuyavian...
This work was conducted to study the effect of rumen-protected choline (RPC) addition on milk performance and blood metabolic parameters in transition dairy cows. In Experiment 1, fourteen Chinese Hol...
Reciprocal effects among local breeds and additive and heterosis effects were estimated for total milk production per lactation (TLP), lactation length (LL) and daily milk yield (DMY). Procedures for ...
