Abstract

The trial will be performed at the Sheep Production Laboratory from the Department of Animal Science of FCAV, UNESP, Câmpus of Jaboticabal, SP. Forty Ile de France newly weaned lambs will be housed in feedlot at body weight of 15kg and will receive the following diets: D1: forage + concentrate, D2: forage + concentrate + 20% of peanut meal, dry matter (DM) basis, D3: forage + concentrate + 25% of glycerin, dry matter (DM) basis and D4: forage + concentrate with 10% of peanut meal and 12,5% of crude glycerin, dry matter (DM) basis. The forage will be corn silage with a 40:60 forage: concentrate ratio. The aim will be to evaluate the performance (dry matter intake, body weight gain and feed to gain ratio), the digestibility of nutrients (DM, OM, CP, EE, NDF, ADF, TCHO, NFC and CE), the nitrogen balance, the quantitative characteristics of the carcass (hot and cold carcass yields, biological yield and weight loss in cooling), the meat qualitative characteristics (pH, temperature, color, water holding capacity, water loss during thawing, weight loss in cooking, shear strength, sarcomere length, number of substances reactive to the acid 2-thiobarbituric and sensory analyses), the centesimal composition (humidity, protein, fat and mineral matter), the profile of fatty acids, the level of cholesterol of the meat and meat indexes (desaturase, elongase, atherogenecity and thrombogenecity) from the Longissimus lumborum muscle, and an economic analysis of the experimental diets related to gains in carcass. The Semimembranosus muscles will be removed of the carcass after 24 hours of cooling, and will or will be not submitted to maturation, and evaluations of the weight loss in cooking, shear strength and microbiological analyses will be done. A completely randomized design will be used, with two treatments and 10 replicates (maturation) and four treatments and eight replicates (to the other analyses). Means will be compared (Tukey test, 5% significance level), and the analyses of variance according to SAS procedures (2003). (AU)
