The objective of this study was to evaluate the effect of addition of different levels of cottonseed (0, 14.35, 27.51 and 34.09 kg/100 kg) in the diet of Nellore steers on the meat characteristics. Thirty-six steers (average initial body weight of 333.50 and average age of 20 months) were kept in feedlot stalls for 94 days, each stall with three animals. The experiment was a completely randomized design with four treatments and nine replications. The values of protein, fixed mineral […]

The objective of this work was to evaluate sensory atributes (tenderness, odor, flavor, juiciness and color) and physical attributes (shearing force, cooking losses and the color parameters of L*, a*, b*) in addition to content of iron in the meat of Santa Inês (SI), Dorper × Santa Inês (DP × SI) and Without Definite Breed Pattern (WDB) lambs, finished in feedlots, in function of two roughage:concentrate (50:50 and 20:80) relationships in the diet. It was used 54 whole lambs (18 […]

The objective of this work was to evaluate the influence of using silk flower hay replacing corn and soybean meal on physical-chemical and sensorial traits of lamb meat. It was used 32 intact Morada Nova male lambs (12.7 ± 2 kg initial body weigth) on feedlot system, distributed in a completely randomized design with four levels (0, 15, 30 and 45% on dry matter basis). The use of silk flower hay in the diet influenced quality of meat and carcass, […]
