WEIGHT AVERAGE DAILY GAINS AND BIOMETRIC MEASURES IN KIDS AS AFFECTED BY GENOTYPE, SLAUGHTER WEIGHT AND SEX

Abstract

The objective of this study was to evaluate the effect of genotype Alpine, ½ Boer + ½ Alpine (½ BA), ½ Anglo Nubiano + ½ Alpine (½ ANA), ¾ Boer + ¼ Alpine (¾ BA), ¼ Boer + ¼ Alpine + ½ Anglo Nubiano (Tricross), gender and slaughter weight (25, 30 and 35 kg) on the performance and biometric measures of kids from dairy goat herds reared on intensive feeding systems. The evaluated traits were: weight at birth, 28 and 60 days old and age at 25, 30 and 35 kg. Biometrics measures: score, body length, previous and posterior height, leg perimeter, rump and chest width. Boer and Anglo Nubiano crossbred with Alpine improved corporal score and weight at 28 and 60 days old. Males reached slaughter weight at 30 and 35 kg more precociously than females. Crossbreed Boer and Anglo Nubiano reached earlier 25, 30 and 35 kg than Alpine. The greater was the slaughter weight the higher was corporal score and biometric measures.
