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

A total of 4627 records on preweaning growth traits, birth weight (BW), weaning weight (WW) and preweaning daily gain (ADG) of Hanwoo's born form 1970 to 2005 were collected from Hanwoo Experiment Station, National Livestock Research Institute. Variance components and heritabilities of BW, WW and...

Abstract

The Hissardale breed of sheep consists of 7/8 Merino and 1/8 Bikaneri and managed at the Livestock Experiment Station, Jahangirabad, district Khanewal (Pakistan) was used in the present study. Data on 5260 birth records of 1179 Hissardale sheep during 1978-95 were analysed using Harvey's mixed...

Abstract

The objective of this study was to estimate (co)variance components and genetic parameters such as heritabilities and correlations and genetic and phenotypic trends for birth weight (PN), weaning weight (PD) and 205-day adjusted liveweight gain (GNDA) in Devon cattle in Brazil. A total of 23 369...

Abstract

The genetic association between individual birth weight and litter birth weight (LBW) was analysed on records of 14 950 crossbred pigs born between 1988 and 1994 at the pig breeding farm of the University of Kiel, Germany. Phenotypically, preweaning mortality of pigs decreased with an increase in...

Abstract

Data collected at the Korean Native cattle Improvement Centre and at national and provincial testing stations were analysed using derivative-free Restricted Maximum Likelihood and BLUP animal model estimations. The direct and maternal h2s were 0.24 and 0.15 respectively for birth weight, and 0.51...

Abstract

Data on 842 Guzerá calves, sired by 22 bulls and born in Brazil in 1979-84, were analysed. Birth weight, body weight at 8 months (weaning), daily gain to weaning, body weight at 12 months and daily gain to 12 months averaged 28.07, 152.33, 0.51, 186.85 and 0.43 kg respectively, the average annual...

Abstract

Body weight at weaning of 1002 Ayrshire × Boran crossbred calves averaged 138 kg. The weaning weight of calves born in Aug.-Oct. and Nov.-Feb. was 20.2 and 1.0 kg respectively higher than average, and that of calves born in Mar.-May and June-July was 19.9 and 2.5 kg below the average weight. The...

Abstract

Data on 3438 Pelibuey lambs were analysed, using 2 models including environmental or genetic factors. Birth weight, weaning weight and preweaning daily gain were significantly affected by year of birth, type of birth (single or twin) and flock using both models, and by sex of lamb and month of...

Abstract

Data on 2550 Nellore calves, born in 4 herds in Brazil in 1975-1980, were analysed. Based on paternal half-sib correlations, the h2s of birth weight, weaning weight (corrected to 205 days), preweaning daily gain and the relationship of weaning weight with the herd average were 0.28±0.06, 0.28±0.06, ...
