“…Low breast and rib points yield of 13.20; 12.19; 11.82% for control group and groups with 15% glycerin and 30% glycerin observed in this study was similar to that achieved by Siqueira & Fernandes (1999), who obtained 12.3% in Corriedale lambs and crossbred (Ile de France × Corriedale) lambs.…”

“…Loin yield averages were similar to those observed by Siqueira & Fernandes (1999), 10.2% in weaned finishing feedlot Corriedale lambs and crossbred (Ile de France × Corriedale) lambs. Loin weight was, on average, superior to that obtained by Garcia et al (2003), which was 0.78 kg.…”

“…Neck yield obtained by Zundt et al (2006), in Santa Inês lambs was 6.07%, a value inferior to the means obtained in this study (6.38 to 8.33%), yet similar to the percentage (8%) found by Siqueira & Fernandes (1999). Lage et al (2009) found no effect on weight when studying confined Santa Inês lambs, as they reported weights of 0.69; 0.76; 0.62; 0.74 and 0.58 when 0; 3; 6; 9 and 12% of crude glycerin was added to the diet, respectively.…”

-This study was carried out to evaluate the influence of diets supplemented with glycerin as an alternative ingredient to corn on the performance and carcass characteristics of Santa Inês confined lambs. The study involved 27 lambs aged 90 days, having an average initial weight of 26.33 ± 0.15 kg. Lambs were randomly distributed into a control group and groups with diets containing 15 and 30% glycerin in the total feed. Diet was formulated with 40% roughage and 60% concentrate.The experimental design was completely randomized, and the production performance and carcass characteristics were analyzed by analysis of variance, and the subjective carcass characteristics, by general linear models. The daily average gain was 0.21, 0.24 and 0.23 kg/day; feeding conversion was 6.39, 5.73 and 5.92 kg of diet/kg BW for control animals, and those fed with 15 or 30% glycerin, respectively, without treatment differences. Lambs were slaughtered, weighing 34 to 36 kg, and average weight of the cold carcass and commercial carcass yield were evaluated. The results were, respectively, 15.97 kg and 49.18%, for control, 15.96 kg and 48.31% for animals fed with 15% glycerin, and 15.79 kg and 47.87% for those treated with 30% glycerin, with no treatment effects. Meat tenderness and cooking loss averages were not affected by diets, with 5.07 kg and 40.45%, 5.10 kg and 40.81%, and 5.27 kg and 39.04%, respectively, for control, and those fed with 15 or 30% glycerin. Therefore, it is possible to conclude that up to 30% of medium purity glycerin in the dry matter of the diet can be used to replace corn, without any negative effect on lamb performance or carcass characteristics.

“…De acordo com Bonifacino et al (1979) e Lloyd et al (1983), a perda ao resfriamento varia de 3 a 4% entre animais puros e mestiços. Todavia, Siqueira & Fernandes (1999) constataram que, tanto os pesos médios da carcaça quente e fria quanto as perdas por resfriamento, foram similares entre cordeiros puros (3,54%) e mestiços (2,83%), o que também foi observado nesta pesquisa com caprinos.…”

Características de carcaça de caprinos de cinco grupos raciais criados em confinamento

et al. 2011

RESUMO -Este trabalho foi realizado com o objetivo de avaliar a influência do grupo racial e da condição sexual nas características da carcaça de caprinos jovens criados em confinamento. Foram utilizados 91 animais, 52 machos e 39 fêmeas, pertencentes a cinco grupos raciais: Alpino, ½Boer + ½Alpino, ½Anglo Nubiano + ½Alpino, ¾Boer + ¼Alpino, e ½Anglo Nubiano + ¼Boer + ¼Alpino. Foi tomado o peso ao jejum, no dia do abate, após 24 horas de jejum de sólidos. Foram tomadas medidas biométricas e de carcaça, objetiva e subjetivamente. O grupo racial influenciou a altura de cernelha, o comprimento interno e externo da carcaça e o comprimento de perna, que foram maiores nos animais Alpinos, bem como a largura do peito, o escore corporal, os índices de compacidade da carcaça e da perna e a cobertura de gordura da carcaça, que foram melhores nos animais com grau de sangue Boer. Animais machos tiveram maior altura de cernelha, medidas da estérnebra com ultrassom, comprimento interno da carcaça, comprimento de perna, profundidade dos tecidos na altura da 3 a e 4 a estérnebras tomadas na carcaça. Nas demais características corporais avaliadas, não foram encontradas diferenças entre grupos raciais e sexo dos animais. O cruzamento do grupo Boer com Alpino reduz o comprimento das carcaças e aumenta a cobertura de gordura e a quantidade de tecidos depositados, mas não influencia o desempenho do animal.Palavras chave: cabritos, conformação, grupo genético, raça, rendimento Carcass traits of characteristics of kid goats from five breed groups raised in a feedlot systemABSTRACT -This study was carried out with the objective of evaluating the influence of breed groups and sexual conditional on carcass traits of young goats raised in feedlot. It was used 91 animals, 52 males and 39 females, belonging to five breed groups: Alpine, ½Boer + ½Alpine, ½Nubian + ½Alpine, ¾Boer + ¼Alpine and ½ Anglo-Nubian + ¼Boer + ¼Alpine. On the slaughter day, the shrunk weight was measured after 24 hours of solid fasting. Biometric and carcass measures were objectively and subjectively taken. Racial group influenced withers, internal and external carcass length, and leg length, which were greater for Alpine animals, as well as chest width, body condition score, carcass and leg compactness index and fat thickness on carcass, which were better in animals with Boer blood degree. Male animals showed greater withers, measures of sternebrae by ultrasound, internal carcass length, leg length, tissue depth height between 3 rd and 4 th sternebrae measured on carcass. On the other body evaluated characteristics, it was not found any differences among breed groups and sex of the animals. Crossing Boer with Alpine reduces carcass length, and increases fat thickness and deposited tissue, however, it does not change animal performance.

“…SOUSA (1993) afirmou que a perna apresenta a maior contribuição na carcaça de um ovino, devido principalmente, ao rendimento superior da porção comestível, onde estão as maiores massas musculares, constituindo o corte mais nobre na espécie.

Dressing of cuts and non-carcass components of lambs fed diets containing different sources of vegetal oil RESUMO Objetivou-se avaliar os rendimentos dos cortes e dos não-componentes das carcaças de cordeiros Santa Inês puros e ½ Dorset ½ Santa Inês, alimentados com dietas con INTRODUÇÃOA importância dos não-componentes da carcaça não está vinculada apenas à possibilidade de aumentar o retorno econômico no momento da comercialização dos produtos ovinos, mas, também, no alimento ou matérias-primas que se perdem e que poderiam colaborar na melhoria do nível nutricional de populações menos favorecidas. Para FRAYSSE & DARRE (1990), estes são constituídos pelo conjunto de subprodutos, que são obtidos após o abate e que não fazem parte da carne. Esse formado pelo sistema
