Abstract

Analysis of 2732 reproduction records in a baluchi flock in Yazd province revealed 60% apparent fertility (EP/EJ) and 40% weaning rate (LW/EJ). There was no incidence of twinning. Records of 1018 lambs on birth weight, weaning weight, average daily gain to weaning and KLEIBER RATIO were analysed by least square method for environmental effects, HERITABILITY estimates and phenotypic and GENETIC CORRELATIONs. The effect of year and age of dam were significant on all traits (p<0.01) with the exception of the dam age on birth weight. Lambs born from 5 years old ewes had the highest weaning weight (27.20 kg), average daily gain to weaning (214.24 g), and KLEIBER RATIO (17.85 g/kg).Baluchi male lambs had significantly (p<0.01) higher birth and weaning weight, average daily gain to weaning, and rate of KLEIBER RATIOn than female lambs.Heritability for birth weight, weaning weight, average daily gain to weaning, and KLEIBER RATIO were estimated 0.08 (0.06), 0.15 (0.07), 0.15 (0.07) and 0.08 (0.06) respectively. Phenotypic and GENETIC CORRELATIONs between birth weight and average daily gain to weaning, birth weight and weaning weight, birth weight and kleieber ratio, average daily gain to weaning and weaning weight, average daily gain to weaning and KLEIBER RATIO and weaning weight and KLEIBER RATIO were 0.06 and 0.11 (0.42), 0.16 and 0.18 (0.24), 0.13 and 0.14 (0.57), 0.99 and 0.99 (0.002), 0.91 and 1.00).0.88 and 0.10 (0.79) respectively.
