The study evaluated the effects of sire breed (SB: Vienna Blue (VB) and Burgundy Fawn (BF)), parity order (P: 1 = nulliparous, 2 = primiparous, ≥3 = multiparous), slaughter season (SS: spring, summer)...
The proportion of variance for service sire was in the range from 2 to 3% (standard error approx. 0.2%) in Czech Large White and 2% (standard error approx. 0.3%) in Czech Landrace for all thr...
Genetic parameters including the proportion of variance for the service sire effect were estimated for number of piglets stillborn (including piglets died until 24 h after birth) and number of pigle...
The Old Kladruber horse is the oldest original Czech horse breed – gene resource, with pedigree records spanning three centuries. Because the population is closed, there is a concern about the loss of...
32 primiparous cows were used. We tested the hypotheses that live weight and milk efficiency were influenced by the system of rearing from the second week of life to weaning, by the sire, and by the s...
The aim of this study was to compare both the performance of litters derived from two sire genetic origins (SGO), Vienna Blue (VB) and Burgundy Fawn (BF), along successive seasons of birth (SB; winter...
A trial was conducted to: i) evaluate the BW growth, energy intakes and energetic efficiency of pigs fed high and low density diets from 27 to 141 kg BW, ii) evaluate sire line and sex differences whe...
The objectives of this study were to estimate genetic parameters and sire breeding values for average daily gain (ADG) and carcass traits using sire-maternal grandsire model with REML approach, sire m...
A total of 1,367 first lactation records of daughters of 81 sires, having 5 or more progeny were used to evaluate sires by 3 different methods viz., least squares (LS), best linear unbiased prediction...
The aim of this study was to investigate genetic development and genotype environment interactions (GEI) in postweaning body weight of fattening bulls at the end of test period (WT-T) under various be...
Reproductive traits of sows are determined chiefly by the genetic background of the dam herself. Whether the breed of the serviced boars also contributes is not yet clear. A total of 8,946 litters of ...
Genetic parameters of live weight at slaughter (LWT), quantity index (QIX), yield grade (YGD), quality grade (QGD), pH of meat, and boiled meat tenderness in terms of mastication (BMAS), shear force (...
The objective of the trial in the test station was to evaluate productive performance with respect to sire-line No. 101, 102, 103 in C-position for LWs × (LW×L) genotype in pigs. The productive perfor...
The present investigation was undertaken to study the effects of non-genetic factors and association among replacement and lifetime production traits. The data on 542 Holstein Friesian cows maintained...
