Title

Effect of different levels of corn gluten feed on performance, nutrient digestibility and carcass characteristics of Afshari breeding fattening lambs

Pages

Abstract

 Background and objectives: Considering that about 70 to 75 percent (in developed countries about 50-60 percent) of the total production costs related to livestock feed. One of the economic methods of production is to use the by-products from agricultural and industrial activities; one of the industrial wastes is Corn gluten feed that can be used in the feeding of dairy cattle, sheep. For this purpose, a comparison have been made regarding of Performance, Carcass traits and digestibility in fattened lambs. The aim of this study was to investigate the replacement of soybean meal with Corn gluten feed in the diet of fattening lambs on Performance, Carcass traits and digestibility. Materials and methods: This experiment was conducted in a completely randomized design with four treatment containing 0, 33, 66 and 100 percent Corn gluten feed was substituted with soybean meal on fattened lambs. Six lambs were given to each treatment with the age of about three months. They were kept individually in separate cages for 16 days of adaptation period and 84 days fattening period. The protein and energy content of diets were equal. Three animals from each treatment were randomly slaughtered and the carcass weight and their components measured. The protein and energy content of diets were equal. Dry matter, ash, crude fiber, and crude fat were determined according to AOAC (2000), crude protein was determined by kjeldahl method (AOAC, 2000), NDF, ADF and by Van Soest (1991). The apparent coefficients of nutrient digestibility were determined using a metabolic cage and all collected feces. Results: The highest daily Feed intake was for lambs fed 100% corn gluten and the lowest daily feed for lambs fed 66% corn gluten (P < 0. 05). Treatments containing 66% Corn gluten feed had the highest body weight (P < 0. 05). In most periods, 66% of Corn gluten feed showed the highest weight gain (P < 0. 05). Feed conversion ratio of lambs receiving 66% Corn gluten feed improved in most periods (P < 0. 05). The digestibility of dry matter, organic matter and protein in 66% substituted treatment were higher and significantly different from other treatments (P <0. 05). Digestibility of cell wall without hemicellulose (ADF), cell wall (NDF), nonfibrous carbohydrate (NFC) and crude fat digestibility (EE) were not significantly different (P > 0. 05). There were significant differences among treatments for all carcass composition (P < 0. 05). The 66% corn gluten level treatment showed the best Carcass traits compared to the other treatments. Dry matter, organic matter, crude protein, ash, crude fat, crude fiber, cell wall without hemicellulose and cell wall were 87. 96, 82. 67, 21. 66, 6. 33, 3. 5, 9. 4, 37. 55, and 12. 70. Conclusion: According to the results mentioned and low-cost of this product compared to soybean meal, up to 66% replacement of soybean meal without adverse effect on Performance is recommended.
