AbstractFull Text

The objective of this study was to evaluate the effect of non-genetic factors on the characteristics of pre-weaning growth in sheep under tropical conditions. The sex of the lamb, the type of birth (single, multiple) and parity number on the birth weight, weaning weight and preweaning daily gain of ...

Abstract

Preweaning growth traits and neonatal weakness (NW) were studied in Red (RB, n=82) and Grey Brahman (GB, n=37) calves. At birth, males calves were heavier than females (31.6±0.9 vs. 28.5±0.8 kg; P<0.002), calves experiencing NW were lighter (29.0±1.1 vs. 31.2±0.6 kg; P<0.06) than normals, and ...

Abstract

Non-genetic sources of variation were investigated for preweaning performance of Creole goats of Guadeloupe using 6375 individual records collected from 1980 to 1994. The analysed sources of variation were litter size, sex, lactation number, year and season of kiddings. Age at first kidding...

Abstract

For 15 515 Nelore and Charolais × Nelore calves in 2 herds in Brazil, birth weight averaged 32.02 and 30.12 kg respectively, and for 14 481 calves of the 2 types, body weight at weaning averaged 207.32 and 192.75 kg respectively and daily preweaning gain 650 and 604 g. All traits were significantly ...

Abstract

Data on 3032 Large White piglets born in Brazil in 1984-87 were analysed. Piglet mortality to 21 days of age ranged from 7.1% to 99.7% for males and from 6.6 to 100% for females, and it was significantly higher for piglets with a low birth weight (<1.1 kg for females and <1.4 kg for males)...

Abstract

The influence of colour of kid, sex, type of birth (single or twin), body weight at birth (BW), and after the 1st (FW) and 2nd (SW) months, and preweaning daily gain (ADG) were used to estimate h2s, and genetic and phenotypic correlations in a flock of Angora goats at Dohok, Iraq. Single-born kids...

Abstract

For 484 Polwarth ewes, lambing in 1979-92, gestation length averaged 148.5 days. Of lambs born, 258 were male and 226 female, and 102 lambings resulted in the birth of twins. The birth weight of 492 lambs averaged 2.74 kg and was significantly affected by sex of lamb, litter size, parity and year...

Abstract

From birth to weaning, 114 calves from primiparous Nelore × Devon cows were grazed on native pasture at a stocking rate of 0.7, 0.8 or 0.9 cow equivalents (400 kg body weight) per hectare. Calf birth weight averaged 29 kg, and was significantly affected by the sex of calf × age of dam interaction,...
