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...
