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, […]

The objective of this study was to evaluate the effects of the genotypes and body condition on the carcass dressing of lambs finished in feedlot. Twenty-four Santa Inês and 24 ½ Dorper × ½ Santa Inês crossbred lambs averaging 19.8 kg of weight and 103 days old were used in the trial. The adaptation period to the facilities and diet was of 14 days. The animals received complete ration with 30% of maniçoba hay (Manihot pseudoglaziovii) and 70% of concentrate. […]

This work was carried out with the objective to evaluate the effects of different levels (0.0 20.0, 30.0 and 40.0%) of whole cottonseed (Gossypium hirsutum L.) of the diet (% DM) on carcass characteristics, cut yields and carcass muscularity of feedlot Santa Inez sheep. Twenty-four sheep with average initial and final body weight of 19.0 and 32,2kg, respectively, and allotted to a completely randomized design, with four diets and six replications. No effect was observed for the inclusion of whole […]

This work aimed at to characterize the effects of the dependent aspects of the genetics of the calves marketed in the state of Rio Grande do Sul, as form of verifying the influence of these in the sale price. They were collected at 13 municipal auction of calves in the State, referring data to the predominant genetic group, size and musculature of the animals of 739 lots of animals corresponding to 11,986 heads. They were evaluate for the price obtained […]

Eighteen lambs averaging initial body weight (BW) of 15 kg were allotted to six groups of three animals (one lamb per diet) and were fed diets with following forage:concentrate ratios (F:C): 1) 40F:60C; 2) 55F:45C; or 3) 70F:30C. Lambs of each group were slaughtered when the animal fed the diet with the highest concentrate level reached 25 kg of BW. Animals were slaughtered after 16 h of fasting (feed and water). After obtaining the slaughter body weight (SBW), animals were […]

The experiment was carried out at Sheep Production Department, Universidade de Marília-SP, to evaluate the effect of energy levels (2.6, 2.8 and 3.0 Mcal ME/kg DM) on objective measures of carcasses and loin, cuts weight and yield and tissue composition and muscularity of carcasses of lambs under creep feeding. Isoprotein rations (18.50 %CP) were fed ad libitum, twice a day. Lambs stayed with their dams until slaughter weight ( 31 kg). After, lambs were fasted, when slaughter live weight was […]
