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

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

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

Data on 35 Black Bengal, 75 Jamnapari × Black Bengal and 74 Beetal × Black Bengal kids were analysed. The survival rate from birth to 15 days of age was 77.5, 86.5 and 84.2% in Jamnapari × Black Bengal, Black Bengal and Beetal × Black Bengal goats resp. Females had a significantly higher survival...

Abstract

Data on 3337 piglets were analysed. Body weight at birth averaged 1.24 and 1.20 kg in ♂♂ and ♀♀ resp. At birth, ♂♂ averaged 38 g heavier than ♀♀, and at weaning ♀♀ were 450 g heavier than ♂♂. Year of birth and parity significantly affected body weight at all ages; the effect of season of birth was...

Abstract

3500 records of reproduction in a 7-yr period of Awassi sheep managed semi-intensively at the Kraim Research Centre were analysed. Pregnancy duration averaged 151.7±2.17 days, and was not significantly affected by litter size, although it was slightly longer in ewes carrying single lambs than in...

Abstract

1483 birth and 1209 weaning records of Dorper lambs in a commercial flock were used to investigate the effects of environmental factors on birth and weaning weights and on preweaning growth and survival. Preweaning survival was relatively high (0.91) and largely independent of known sources of...
