To assess the influence of genotype and diets with different energy levels on the lipid profile of sheep meat, 54 lambs were used (18 animals from each genotype: Morada Nova, Santa Inez and ½Dorper + ½Santa Inez crossbred), distributed in a completely randomized experimental design in a 3 × 2 factorial arragement (three genotypes and two diets). The animals were submitted to two diets, 2.5 Mcal ME/kg DM and 3.0 Mcal ME/kg DM, receiving feed and water to reach the […]

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 performance and nutrient digestibilities of feedlot Santa Inez sheep. Twenty-four sheep with average initial and final body weight of 19.0 and 32.2 kg, respectively, and allotted to a completely randomized design, with four diets and six replications. The dry matter intake in kg/day, %BW and g/kg0.75 was not […]

The objective of this study was to investigate the effects of sex and genotype (breed) on the composition and fatty acid profile of the semimembranosus (SM) muscle of feedlot sheep. Four Santa Inês (SI) males, four SI females, and four ½ Santa Inês x ½ Dorper (SI-D) males were used in this trial. Neither breed nor sex significantly affected the chemical composition of meat. However, the meat contents of phosphorus and calcium were both significantly changed by breed and sex. […]
