Selection Indices for Genetic Improvement in Malabari Goats

摘要

Data on 845 kiefs from the farmer's flocks of All India Co-ordinated Research Project for Malabari goats jwere analysed for the development of selection indices. Eleven selection indices were constructed by incorporating growth traits (body weight, chest girth, body length and height at withers at below one, three and six months of age in different combinations). These were developed by assigning economic weights to the traits. Index I_(11) involving all the traits was found most appropriate with anaggregate economic generic gain of 6.2974 and an expected genetic gain of 1.490kg for body weight at six months of age followed by I_(10) and I_9.
