Performance of Hereford and two-breed rotational crosses of Hereford with Angus and Simmental cattle: I. Calf production through weaning.
Cow size, reproductive traits and calf performance through weaning were evaluated in a range environment for Simmental (S) x Hereford (H) and Angus (A) x H crosses in two-breed rotations and straightbred H. Data were grouped into seven dam breed categories: straightbred Hereford (H), crossbred F1 S x H cows (SH), S x H cows of low percentage H (SHS), S x H cows of high percentage H (HSH), F1 A ...
متن کاملPerformance to Weaning of Three-Breed Cross Calves Sired by Charolais and Limousin Bulls
Various two-breed cross cow groups were mated to Charolais and Limousin bulls to produce a total of574 three-breed cross calves over a two-year period. Average birth weights were 81.2 Ib and 76.2 Ib for calves produced from Charolais and Limousin sires, respectively. Calving assistance was required for 12.4 percent ofCharolais-sired calves and 4.0 percent of the Limousin-sired calves. Charolais...
متن کاملFattening performance of crossbred (Polish Holstein-Friesian × Hereford, Limousin or Charolais) bulls and steers offered high- wilted grass silage-based rations
7 CHILEAN JOURNAL OF AGRICULTURAL RESEARCH 76(1) JANUARY-MARCH 2016 3 ULY-SEPTEMBER In Poland beef cattle are usually fed high-wilted grass silage offered ad libitum and supplemented with concentrate, whereas ‘Limousin’, ‘Charolais’ and ‘Hereford’ bulls are the most frequently crossed with dairy cows to produce beef hybrids. The aim of this study was to determine the fattening performance of hy...
متن کاملComparision of Genetic Parameters for Calving Difficulty in Angus, Charolais, Hereford and Limousin
Data on Angus (ANG), Charolais (CHR), Hereford (HER) and Limousin (LIM) cattle were used to estimate genetic parameters for calving difficulty (CD) and to quantify genetic relationships among CD, birth weight (BWT) and gestation length (GL). Bayesian analysis was carried out using Gibbs sampling to obtain means of marginal posterior distributions. Estimated heritabilities for direct genetic eff...
متن کاملMilk production of crossbred daughters of high- and low-milk EPD Angus and Hereford bulls.
Milk yield from 273 Angus- and Hereford-sired cows and preweaning performance of their calves were used to determine how accurately milk EPD of Angus and Hereford sires predicted milk production of crossbred daughters and subsequent calf performance. Mean milk EPD (kg) for high Angus (HA), low Angus (LA), high Hereford (HH), and low Hereford (LH) bulls (n = 41) selected as sires were +8.7, -6.2...
