Association between growth and reproduction traits of sangamneri goat under field conditions

Abstract

At the AICRP on Goat Improvement (Sangamneri field unit), Mahatma Phule Krishi Vidyapeeth, Rahuri, Maharashtra, India, the data on 492 Sangamneri kids born between 2006 and 2014was collected for growth and reproductive traits and adjusted for significant non-genetic factors. The adjusted data was used to estimate the genetic and phenotypic correlations among the growth and reproduction traits. The genetic and phenotypic correlations among 1 month body weight (W1), 3 months body weight (W3), 6 months body weight (W6), 9 months body weight (W9), 12 months body weight (W12), age at maturity (AM), age at first kidding (AFK), prolificacy (PROL.), first service period (FSP) and first kidding interval (FKI) were estimated for Sangamneri goat. The positive and significant association amongst growth traits and negative and significant association amongst growth and reproduction traits indicate that the early stage body weights especially body weight at weaning stage can be considered for selection of animals to enhance the growth and reproduction traits.
