Effect of urea treated paddy straw supplementation on the performance of crossbred cows
نویسندگان
چکیده
An experiment was conducted on eight crossbred cows of similar age (4-5 yr) and body weight (306.96 ± 12.57 kg) to elucidate the effect of urea treated paddy straw supplementation on their feed intake, milk production and blood biochemical profiles. Crossbred cows were randomly divided into two equal groups and fed a concentrate mixture and paddy straw to meet their nutrient requirement. Group I served as control (without any supplementation), whereas animals in groups II supplemented with ad libitum urea treated paddy straw. This experimental feeding lasted for 60 days, during which daily dry matter intake and milk production was recorded. Milk samples were collected daily to estimate the protein, fat and solid not fat. Blood samples were collected at 30 days of the experimental feeding to study blood biochemical parameters. Results revealed significant (P<0.05) increase in dry matter intake from 5.72 kg to 7.80 kg and milk yield from 3.15 kg to 4.08 kg without affecting the composition of milk in cows. The serum urea did differ significantly (P>0.05) among two treatment groups.
