while supplementation of urea enriched paddy straw. The cost of feed per animal per day was not differed
among treatment groups and however the cost of feed per kg milk production (Rs.) was significantly (p<0.01)
decreased by 6.43 % in urea treated paddy straw than untreated paddy straw. Similar to the present study,
Paudel et al. (2015) observed that the feeding of urea treated paddy straw in dairy cattle increased the milk
production.

Introduction
Most of the dairy cattle in Tamil Nadu are usually fed with paddy straw characterized by high indigestible
fibre due to increased lignifications of cellulose. The paddy straw is also deficient in fermentable energy,
protein and the digestible crude protein content of paddy straw is zero. The low nutritive value of paddy straw
coupled with low digestibility can impairs the intake, ruminal functions and thus animal productivity. This
situation strongly demands the improvement of the nutritive value of paddy straw through various treatments
