The aim of the study was to characterize nucleotide sequence polymorphisms in the bovine PTPRQ gene, to search for their possible effect on the expression of myogenic factor 6 (MYF6; MRF4) and myogeni...
Adipose tissue in the loin muscle area of beef cattle as a marbling factor is directly associated with beef quality. To elucidate whether properties of proteins involved in depot specific adipose tiss...
The objective of this study was to evaluate the usefulness of young bulls’ conformation scores in a national type evaluation system. For this purpose the genetic correlations between conformation tr...
Heat shock protein 70 (HSP70) is considered as a gene which affects semen quality traits. The present study attempted to investigate the relationship between the HSP70 expression level and motility of...
Objectives of the study were to examine alternative measures of growth potential of bulls in testing stations, determine whether genetic parameter estimates of such traits changed over time, and exami...
Older animals were generally fatter and their carcasses contained lower proportions of high-priced meat (P < 0.01) and bones (P < 0.05). Bulls exhibited lower contents of dry matter (P < 0...
However, the HOS-2 and HOS-3 values in FT semen had high correlations with NRR (r = 0.65, r = 0.66, P < 0.001 at batch level and r = 0.63, r = 0.71, P < 0.01 at bull level), which was comparable t...
The analysis comprised purebred Charolais bull calves (CH) and crossbred bull calves born from Hereford (CH × HE) and Simmental (CH × SI) cows. Body weights and daily gains were measured in subsequent...
The effects of breed and diet containing different types of silages on meat quality parameters and fatty acid profile of m. longissimus lumborum (MLL) were evaluated in a total of 30 Czech Fleckvieh (...
The effects of breed and diet containing different types of silages on meat quality parameters and fatty acid profile of m. longissimus lumborum (MLL) were evaluated in a total of 30 Czech Fleckvieh (...
The aim of the study was to evaluate the growth rate and selected carcass and meat quality parameters in bulls fed a high-grain diet and to compare the results with those obtained in bulls fed a diet ...
The live weights of 8 243 performance-tested bulls from 100 to 400 days of age were analysed using random regression (RR) and single-trait animal models. Evaluations were done for live weight at 400 d...
A total of thirty-four Czech Fleckvieh (CF), Charolais (CH) and Charolais × Czech Fleckvieh (CH × CF) bulls with an average weight of 284 kg were included in the experiment and fed ad libitum two mixe...
6 508 bulls of dual-purpose cattle at performance-test stations were weighed at intervals of 30 days from birth to 420 days. After all editing a total of 74 558 weight records were available. Live wei...
Breed effects on live weight gain, slaughter characteristics and carcass composition were compared in Aberdeen Angus, Charolais, Hereford and Simmental bulls. The experiment extended over 2 years and ...
