“…The carcass yields obtained in the present study were smaller than 56.50% and 49.79% obtained for the carcass biological and hot carcass yields, respectively, by Zundt et al (2006) with Santa Ines lambs slaughtered with final body weight of 30.0 kg.…”

-The objective of this study was to evaluate the performance, qualitative, morphometric and quantitative carcass traits of Santa Inês lambs of different frame sizes finished in a feedlot. Twenty 120-day-old intact lambs with a 25.0±3.1 kg average body weight at the beginning of the experiment were used. Lambs received a diet containing 17% crude protein and 2.70 Mcal/kg dry matter. Frame size influenced performance and tissue composition in the carcasses of the lambs. Lambs with large frame sizes showed better carcass conformation compared with those of medium-sized frames. Frame size was found to have a significant effect on rump perimeter. Large-framed lambs showed higher compactness on the carcass index and carcass dressing area compared with medium-framed lambs. The cuts of large-framed lambs weighed more than those of mediumframed lambs. However, no significant differences were found in dressing.

“…Este índice é uma medida indireta da conformação, utilizado para avaliar a produção de músculo de animais com peso vivo semelhante (30) . O valor médio de ICC no presente estudo foi de 0,28, valor superior ao encontrado por Zundt et al (31) utilizando a mesma raça (0,24). Esta diferença provavelmente é resultado dos diferentes pesos de abate entre ambos estudos, em que os autores abateram os animais com média de 29,4 kg, ao passo que neste estudo o peso médio de abate foi de 38,58 kg.…”

Características De Carcaça E Qualidade Da Carne De Cordeiros Alimentados Com Diferentes Teores De Torta De Soja Em Substituição Ao Farelo De Soja

ResumoObjetivou-se avaliar a substituição do farelo de soja pela torta de soja sobre as características de carcaça e qualidade da carne de cordeiros Santa Inês. Foram utilizados 29 machos inteiros, com 23,63 ± 2,44 kg de peso vivo, 80 dias de idade, distribuídos de maneira inteiramente casualizada, submetidos a cinco dietas, sendo que as dietas variaram nos teores de substituição do farelo de soja pela torta de soja de 0, 25, 50, 75 e 100%. Para cada teor de substituição foram utilizados seis animais, mas no teor de 25%, cinco animais. Foram realizadas avaliações das carcaças e retirou-se o Longissimus dorsi para análises da qualidade da carne. As características da carcaça não foram afetadas pelos diferentes teores de torta de soja. Observou-se efeito quadrático para a força de cisalhamento e efeito linear decrescente para a intensidade de odor, mas não foram observadas diferenças nos demais parâmetros. A substituição do farelo de soja pela torta de soja pode ser realizada sem prejuízo à maioria das características da carcaça e de carne e altos teores de torta de soja na dieta podem resultar em benefícios às qualidades sensoriais da carne de cordeiros recebendo dietas concentradas. Palavras-chave: análise sensorial; biodiesel; força de cisalhamento; morfometria; Santa Inês. AbstractThe objective of this study was to evaluate the replacement of soybean meal by soybean cake on carcass characteristics and meat quality of Santa Ines lambs. Twenty-nine intact males were used, weighing 23.63 ± 2.44 kg, at 80 days of age, distributed randomly, submitted to five diets, with the diets differing in the levels of substitution of soybean meal by soybean cake (0, 25, 50, 75 and 100%). Each diet was provided to six animals, except the 25% diet, in which five animals were used. Carcass characteristics were evaluated, and the Longissimus dorsi was removed for meat quality analysis. The different levels of soybean cake did not affect carcass characteristics. Regarding the characteristics of meat, there was a quadratic effect for the shear force and negative linear effect on flavor intensity, but no significant differences on the other parameters were observed. Replacement of soybean meal for soybean cake can be made without affecting most of the carcass and meat characteristics, and

“…The selection for individuals with higher ADG at younger ages could substantially contribute to high production rates. According to Zundt et al (2006) knowledge of the age in which the highest growth rate occurs enables the definition of the most appropriate age for slaughter, thus avoiding high fat deposition in carcass. Landim et al (2007), evaluating the slaughter weight of Santa Ines sheep raised under semiintensive breeding system found ideal slaughter weight of 27.2 kg.…”

-The objective of this study was to characterize body biometrics of Santa Ines sheep during growth. Data from 4,038 animals, males and females, with ages from four to 36 months, from different herds participating in the National Agricultural Fair in Bahia from 2003 to 2008 were used. The characteristics evaluated were: body weight, average daily gain, body length, thoracic circumference, anterior height and posterior height. The mean values found were compared by the Student-NewmanKeuls test. All characteristics studied showed gradual change with aging, and it is worth-noting that age had positive effect on body weight, body length, thoracic circumference, anterior height and posterior height and negative effect on average daily gain.Average daily gain was reduced by 68.5% from four to 36 months of age, while the mean improvements observed in both sexes in this age range, for body weight, body length, thoracic circumference, anterior height and posterior height were 137.8%, 23.5%, 43.2%, 19.3% and 19.6%, respectively. However, the increments for body weight, body length and thoracic circumference were higher until 12 months of age, when an increase of 72.7%, 14.6% and 24.8% in their respective characteristics was verified. For anterior height and posterior height, the greatest increase occurred up to eight months of age with improvement of 8.4% for both measures. Santa Ines sheep have different growth rates for body measurements; whereas growth in posterior height stabilizes earlier, the thoracic circumference, along with body weight, remains growing for longer time.
