grandiflora supplementation increased milk yield by 270 ml / day due to additional protein in the diet of
milch cows.

Introduction
The paddy straw is one of the important crop residue for feeding of dairy cattle in Tamil Nadu. The paddy
straw contains high indigestible fibre due to increased lignification of cellulose. The low nutritive value of
paddy straw reduces digestibility, intake, rumen fermentation and production. This compels the improvement
of the nutritive value of paddy straw through various processing methods for the efficient utilization.
Processing of paddy straw was made in the past to improve the quality through chemical treatment by sodium
hydroxide and anhydrous ammonia treatment, which resulted in improving the digestibility and protein but its
use, remained limited due to a high cost and environmental pollution. Alternatively the fertilizer grade urea
has been used for improving the poor quality paddy straw. The enriched paddy straw was improved the milk
production in dairy cattle (Paudel et al., 2015). Hence the present experiment was carried out to study the
effect of supplementing urea enriched paddy straw on milk production of dairy cattle under field condition.

Materials and methods

Twelve Jersey cross bred dairy cattle with uniform size body weight were selected and divided into two
groups with six animals each and they were fed with urea treated and untreated paddy straw for a period of 60
days under field condition. The dairy cattle were fed with measured quantity of paddy straw, green fodder and
concentrate mixture separately and left over were recorded to study the dry matter intake (DMI) per animal
per day. They were allowed to drink free access of water and reared under standard manage mental practices.
The dung samples were collected during the last week of trial for digestibility study. All data were statistically
analyzed.
Results and discussion

There was no significant difference in DMI and DDMI between urea treated and untreated paddy straw
supplemented dairy cattle. The milk yield was significantly (p<0.01) increased by 5.2 % in urea treated
paddy straw than untreated paddy straw. The fat percentage of milk in urea treated paddy straw was also
significantly (p<0.01) increased by 4.02 % than untreated paddy straw. The SNF percentage was not altered
