Itwas evaluated qualitative characteristics of confined hair sheep submitted to diets with two energy levels. Eighteen lambs from each genotype were used: Morada Nova, Santa Inez and Dorpper x Santa Inez crossbreds. The rations with the lowest and the highest energy level were made up with 2.5 and 2.94 Mcal EM/kg DM, respectively. It was evaluated conformation and finishing carcass, in addition to leg tissue composition. The score for conformation was significantly higher for animals kept in diet with the highest energy level and for Dorpper x Santa Inês crossbreds. Animals from Santa Inez and from Dorpper x Santa Inez breeds showed score for meat color close to red class, while Morada Nova genotype was close to slightly dark red. The muscle:bone ratio for... |

The objective of this study was to investigate the influence of genotype and the energy concentration in the diet on the sensorial and chemical quality of lamb meat. It was evaluated samples from 18 Morada Nova animals, 18 Santa Inez animals, and 18 Santa Inez x Dorper crossbred animals, totalizing 54 animals. The animals were kept with two diets, with energy concentrations of 10.46 and 12.56 MJ ME/kg, respectively, and slaughtered at 30 kg average weight. It was determined contents of protein, moisture, fat and ash, as well as cooking loss, water-holding capacity, shear force, and sensorial attributes of flavour, firmness and juiciness of the meat. Genotype influenced the chemical composition of lamb meat because animals of Morada Nova breed presented the... |

Este trabalho foi realizado com os objetivos de avaliar os efeitos da alimentação e do genótipo sobre as características quantitativas de carcaça de cordeiros terminados em confinamento e estimar sua margem bruta. Foram utilizados 18 cordeiros de cada genótipo: Morada Nova, Santa Inês e mestiços Dorper × Santa Inês. As rações foram constituídas de 2,5 Mcal EM/kg MS e 2,94 Mcal EM/kg MS. Utilizou-se um delineamento inteiramente casualizado, em esquema fatorial 3 × 2. As dietas influenciaram o ganho de peso diário, o peso de corpo vazio, o escore corporal, a eficiência alimentar e o tempo de confinamento, enquanto o genótipo promoveu diferenças em todas as variáveis estudadas. A densidade calórica das dietas influenciou os rendimentos biológicos, de carcaça... |

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 desired average live weight of 30 kg, when they were slaughtered. Total lipids, cholesterol, phospholipids and fatty acids profile of the Longissimus muscle were assessed. Diet and genotype did not influence the total lipids, cholesterol and phospholipids contents. The diet with the highest energy... |
