Abstract

This review of literature was conducted to update individual estimates of genetic parameters for preweaning growth traits of cattle and to report the overall means, ranges and marginal means of estimates of the genetic parameters by breed of cattle and statistical model in order to investigate the...

Abstract

The objectives of this study were to assess the risk associated with proportion Brahman inheritance, cow age, dystocia, and birth date weather conditions on calf vigor at birth (n=3,253) and preweaning mortality (n=3,631), and to estimate heritabilities for these traits. Calves that had poor vigor...

Abstract

Variance components were estimated using data from Brahman (4497 calves from 266 sires and 1311 dams) cattle at ANSA Genetics, Philippines. The traits were birth weight (BW), preweaning average daily gain (PRADG), preweaning gain (PRGAIN), and adjusted 210-day weaning weight (ADWW). The phenotypic...

Abstract

The genetic parameters in growth traits in beef cattle and milk yield and fat percentage in dairy cattle were estimated utilizing the farming system research and extension approach to collect pedigree and management information. The results of the long-term study showed higher additive individual...

Abstract

Data on 439 Brahman and grade Brahman (≥7/8 Brahman) calves were analysed. Grade Brahman calves weighed more (P<0.01) at birth and gained more (P<0.01) to weaning than Brahman calves, although there were no differences between the 2 types in size of the navel flap (sheath). Males exceeded...

Abstract

First-cross calves of Simmental, Friesian and Brahman sires were compared with purebred calves of Hereford sires over a 5-yr period at Grafton. There was a total of 775 calves, sired by 205 bulls, with complete records of performance from conception to weaning. Analyses were conducted to determine...

Abstract

Data on 502 purebred Brahmans and crosses of Brahman and Charolais with indigenous zebus were analysed. For Brahman, 1/2 Brahman, 3/4 Brahman, 7/8 Brahman, 15/16 Brahman, 31/32 Brahman, 1/2 Charolais and 3/4 Charolais calves, birth weight averaged 29.7, 36.3, 30.4, 31.6, 30.4, 29.3, 32.9 and 35.0...
