Abstract
It is important to understand the scientific basis of raising goats to improve production and productivity of goats. This is a review article to document available literature on the effects of non-genetic factors on productive and reproductive traits of indigenous goats in Nepal. The review included journal articles, published reports, technical bulletins, conference proceedings, post-graduate and doctoral dissertations. The study revealed that altitude, season of conception, season of kidding, number of kid at birth, parity, size of doe are the major factors affecting productive and reproductive traits of indigenous goats of Nepal. These factors should be carefully considered to promote the indigenous goat production in commercial scale farming.
Highlights
Livestock is an integral part of crop-livestock mixed farming systems in rural area where, goat (Capra hircus) occupies an important consideration
3.1 Reproductive traits The reproductive trait is fitness trait concerned with reproduction and viability
Some of the important factors affecting the reproductive traits are the breed of goat, the location of rearing, the season of conception, the season of kidding, dam's birth type, the age of kidding and health care and nutrition
Summary
Livestock is an integral part of crop-livestock mixed farming systems in rural area where, goat (Capra hircus) occupies an important consideration. It has been reported that about 86% of meat demand of goat is fulfilled by domestic production [1] Though it seems to be a growing business, there has not been major uptake of commercial goat farming in Nepal. Kolachhapati et al [4], reported that the productive traits: birth weight, weaning, and post-weaning weight and reproductive traits: age of the first conception, first kidding, gestation length and kidding interval vary greatly due to the non-genetic or environmental factors. Such factors include the season of kidding, dam’s parity, sex of kid, birth type, and altitude. This review paper describes such non-genetic (environmental) factors which affect the productive and reproductive traits of the indigenous goat of Nepal
