Abstract
1. The paddy straw treated with 4% urea at 50% moisture level, and stored for a period of 4 weeks gave significantly better performance in enhancing its protein percentage and in lowering fibre and total oxalate contents, which, in turn, have increased dry matter and protein degradabilities in the rumen, as well.
2. In in-vitro studies, 4 or 5% urea treated paddy straw, stored for 3 to 4 weeks period at 2 to 4 hours of incubation, appeared to be the best in attaining peak concentrations of total-N, NH3-N and TVFA.
3. The feeding of 4% urea treated paddy straw, stored for 4 weeks, at 50% moisture level, without concentrate mixture, proved to be an improved roughage, having better nutritive value and palatability for the main tenance of buffalo-calves. Moreover, supplementation of concentrate is beneficial in respect of proper growth rate, digestibility co-efficients, feed efficiency ratio and cost of production.
4% urea treated paddy straw at 50% moisture level and stored for 4 weeks, mixed with karanj cake. containing concentrate mixture, exhibited maximam digestibility of nutrients, retention of nitrogen, feed gain ratio and cost, per kg body weight gain, along with highest growth rates in 150 days, without affecting the normal health of the animals in any way.
Thus, it may be concluded that 4% urea treatment of paddy straw at 50% moisture level, when stored for 4 weeks, has pronounced effect, so as to bring about an overall improvement in its nutritive values as well as in the productive performance of animals.
