Material type: BookPublisher: 2011Subject(s): Department of Animal NutritionDDC classification: 1341,T Dissertation note: At present, 121.1 million heads of animals in Pakistan annually require about 10.9 and 90.36 tons of crude protein (CP) and total digestible nutrients (TDN), respectively. However the respective availability of these two nutrients is 6.7 and 69.0 million tons and thus, CP and TDN are 38.10 and 24.02% deficient per annum. 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 for fattening of male Lohi lambs. The study was conducted in three phases. In phase one, bovine rumen contents were collected from the slaughter house near Bakar Mandi and were analyzed at Nutrition laboratory, UVAS, Lahore in triplicates before ensiling. In phase two, ensiling of wheat straw (Urea treated @4% of DM of wheat straw and also another ensiling without urea treatment) along with rumen contents will be done with or without 7% addition of molasses for minimum 60 days at Ravi Campus, Pattoki. pH of silages1,2,3&4 after 60 days was 4.78,4.70,4.92 and 5.11 respectively. The silage containing rumen contents and wheat straw showed a increase in C.P as compare to simple rumen contents and silages which were urea treated have significant (p<0.05) increase in C.P. In phase three, a metabolic trial was conducted at Ravi Campus Pattoki, in which 25 male Lohi lambs were fed the diets having total mixed ration (100%TMR) (Tc), 70%TMR with 30% silage1 (T1), 70% TMR plus 30% silage2 (T2), 70%TMR with 30% silage3 (T3), and70% TMR plus 30% silage4 (T4). The data thus obtained was statistically analyzed using one way analysis of variance (ANOVA) technique. The significant differences between means were tested by Duncan's Multiple Range test. DM intake was significantly (P<0.05) higher in control group than other groups offered silages containing rumen contents. There was non significant difference (P>.05) in DM intake between T1.T2 & T3. T4 was non significant to all other treatments. Statistical results showed non significant difference (P>.05) in total weight gain among all the treatments however maximum weight gain was observed in control treatment. Feed efficiency was also non significant (P>.05) among all the treatments. So we can use processed rumen contents as cheap protein source in small Ruminant feed. There were no harmful effects on health of lambs during whole trial. So we can replace 30% of conventional TMR with Rumen Contents safely.Item type | Current location | Collection | Call number | Status | Date due | Barcode | Item holds |
