Large ruminants such as cattle continue to play an important role in the livestock production system in India. Indian cattle breeds are of smaller mature body size, grow at slower rate and produce a low quantity of milk as compared to the breeds found in temperate countries. However, the breeds are hardy, and well adapted to heat stress and poor quality diets, a situation which is characteristic of tropical countries. The nutrient needs of these animals probably differ from those prescribed in the feeding standards of temperate countries (NRC, 1989; AFRC, 1990) because of differences in genetic makeup, mature body size and growth rate, quality of feeds, climatic conditions and differences in efficiency of nutrient utilization. Very few studies have been conducted so far to measure nutritional requirements of tropical breeds, which is perhaps the most important consideration to obtain the best efficiency in any type of production system. Knowing the properties of the feed is equally important. Singh et al. (2003) reported that elevating feeding plane by 20% above NRC (1989) feeding standards during 60 d prepartum to 120 d postpartum period improved productive and reproductive performance of high yielding Indian cows. in this situation it is very important to have such type of fodder which enhance the milk production of cow. soya been is one of them. in india soya been is grown widely in northern and central part. soya been is a reach source of protein and fat content. it is mainly use for oil extraction. after oil extraction its by product can be use to feed the animal which can supplement the nutrient requirement of cattle. energy requirment in cattle
The most important item in an animal’s diet and overall feeding standards is based on energy needs. Meeting the energy requirements of an animal can be a major cost in feeding. Animals
