Processing, Nutritional Evaluation And Utlilization Of Rumen Content For Fattening Of Nili-Ravi Male Calves - 2010

The cost of feed, as percentage of total production costs, accounts for about 50-60% of ruminant feeding systems. According to estimates, Pakistan is deficient by 40 and 80 percent in forage and concentrate feeds. For economical production of balanced feed for livestock, poultry, fish and pet animal, non-conventional feed resources need to be explored to find solution to the existing gaps. For this purpose the present study was conducted to determine the nutritional profile, processing and utilization of rumen contents in buffalo feed. The study was conducted in three phases. In phase one, bovine rurnen contents were collected from the slaughter house near Bakar Mandi and were analyzed at Nutrition laboratory. UVAS, Lahore. In phase two, rumen contents were ensued with wheat straw. with and without addition of 6% molasses for a period of 90 days at Ravi Campus, Pattoki. Proportion of'rumen contents and wheat straw were 1:1 on DM basis. Wheat straw was also treated alone by reducing its DM to 44% with water and by addition of 6% molasses. In two types of silages the wheat straw was urea treated @ 4% on DM basis of wheat straw by making 25% solution. The pH of silagesi (containing rumen contents and wheat straw 50:50 on DM basis) of ruinen contents is 4.78 and of silage2 (containing rumen content, wheat straw and molasses. 47:47:6 on DM basis respectively) is 4.70. The pH of silage3 (containing rumen contents and wheat straw (urea treated), 50:46:4 respectively) is 4.92 and pH of silage4 (containing rumen contents and wheat straw (urea treated) and molasses, 47:43:4:6 respectively) is 5.1 Irespectively. The silage containing rumen contents and wheat straw showed a increase in CJ' as compare to simple rumen content and silage which were urea treated have significant (p
