Abstract

The effect of genotype and litter size on pre-weaning and post weaning body weight and linear body measurements of rabbits was observed using two breeds of rabbits-Dutch belted (Dutch) (DUT) and New Zealand White (NZW) rabbits. Four genetic groups were generated from the two breeds namely: (DUT X...

AbstractFull Text

Data from 195 domestic rabbit (Oryctolagus cuniculus) individuals obtained from three consecutive mating, each from fifteen does, were used to estimate repeatability for litter body weight at birth, 7, 14, 21 and 42 days respectively. The analysis of variance was obtained in a balanced design with...

Abstract

The objective of this study was to estimate the heritabilities of stillbirth and preweaning mortality in a Zebu herd in the tropics of Mexico. The data collected were for cows calving over a 21 years period (1989-2009). The base population was commercial Zebu cattle. The model included the fixed...
