Abstract
1.Since greater emphasis is being given to rear the goats under stall feeding system and to improve their productivity by cross breeding and optimum feeding, an investigation was carried out to evaluate the significance of major nutrients like energy and protein in various proportions on different aspects of goat production. The cost of feed being the major input item in any animal production, is required to be minimized by efficient utilization of the nutrients in the animal body as well as incorporation of cheaper unconventional ingredients in the feed. From the present studies broadly based on above aims and objectives, following conclusions were drawn. 1. The growth rate of the cross-bred kids could be improved by increasing the energy levels in the ration to some extent. The levels of protein in the ration could be reduced by 20 % without having significant adverse effects on the body weight gain provided the energy levels are adequate.
2. The reduction of both protein as well as energy in the ration of growing cross-bred kids had very drastic effects on the body weight gain.
3. The variations in the levels of energy and protein in the ration does not affect the amount of the daily feed intake, The digestibility coefficients of feed dry matter as well as the nutrients like crude protein, crude fibre, ether extract, nitrogen-free-extract, total carbohydrates, organic matter and gross energy have been lowered with the reduction in energy content of the ration.
