EFEITO DO PLANO NUTRICIONAL SOBRE AS MEDIDAS BIOMÉTRICAS DE CORDEIRAS DURANTE A FASE DE CRESCIMENTO

Abstract

The aim of this study was to evaluate the influence and relationship of two growth rates with body development lambs, by monitoring the body measurements. We evaluated 20 Bergamasca lambs kept confined and offered a diet formulated to obtain an average daily gain weight (ADG) of 180 grams (treatment Low) and 300 grams (treatment High). Every 14 days, the animals were weighed, given the body condition score (BCS), height, chest girth, neck and shin. To evaluate the data we used analysis of variance and correlation with Spearman significant difference when P<0.05. Lambs of treatment High showed the highest ADG, BCS and biometric measurements, in addition, in both treatments, the biometric pattern correlated positively with each other and the body weight. Therefore, food differentiation had a direct effect on the development of growing lambs.
