Influência do sexo e do sistema de terminação de cordeiros Texel × Corriedale na qualidade da carcaça e da carne

Neste trabalho o objetivo foi avaliar o efeito do sexo e do sistema de terminacao de cordeiros Texel × Corriedale sobre as caracteristicas subjetivas da carcaca e as medidas instrumentais e quimicas da carne. Foram utilizados 90 animais, 45 deles cordeiros machos nao-castrados e 45 femeas, mantidos em pastagem com a mae ate o desmame (70 dias); e terminados em tres sistemas de producao: apenas pastagem; mantidos na pastagem com a mae e pastagem com suplementacao (casca de soja em nivel correspondente a 1% do peso vivo dos cordeiros). Apos o abate dos animais, as carcacas foram armazenadas em câmara fria (1oC, 24 horas) para medidas de pH, marmoreio, estado de engorduramento, cor e textura. Na sequencia, foi retirado o musculo longissimus dorsi da meia-carcaca, para a analise instrumental e quimica. A analise de variância e o teste de Tukey foram utilizados para comparacao da media a 5% de significância. Nao ocorreu interacao de sexo e sistema de terminacao dos animais nas caracteristicas avaliadas na carcaca. Igualmente, nao ocorreu interacao entre sexo e sistema de terminacao, porem os fatores isolados tiveram efeito significativo na forca de cisalhamento e nos teores de umidade e gordura. A carne dos machos e dos animais terminados mantidos com a mae apresentam maior resistencia a forca de cisalhamento e maior umidade, porem menor teor de gordura.

ECONOMICAL VIABILITY OF A LAMBS FINISHING SYSTEM IN THE CAMPAIGN REGION/RS

The study was conducted between March and June in a particular property of a member of the Association of Sheep Breeders of Dom Pedrito (ACODOPE). Sample consisted of 60 lambs, 50 animals and 10 Corriedale breed Texel, all barrows, milk tooth, with five to seven months old. Was sought throughout the experiment to assess the cost and profitability of a lambs finishing system. The animals were weighed throughout the experiment for the control of weight gain. To achieve the exact results of the production were evaluated and represented all the costs of implementation and operation of confinement as: Fixed Costs, Variable Costs and Cost of acquisition of animals. It was observed that the animals Texel lot remained less time to reach slaughter weight, therefore the cost of producing them was inferior to the other. Still had a loss of R

It was evaluated the influence of rice oil addition on the milk production and chemical composition, of Corriedale multiparous sheep fed commercial diet with and without rice oil addition, containing 4.36% and 6.56% of ether extract, respectively. The mechanical milking was done once a week in the morning. Besides milk production the following components were evaluated: fat, protein, lactose and total solids. The milk production, as well the chemical components as lactose, protein, fat and total solids, were not influenced by diet increase of ether extract through rice oil addition.

Carne bovina: Percepções do consumidor frente ao bem-estar animal–Revisão de literatura

The objective of this work was to evaluate the effect of sex and of three finishing systems on sensory traits of Texel × Corriedale lamb meat an on the consumer acceptance of the meat. It was used 90 animals, 45 non-castrated male lambs and 45 females kept on pasture until weaning (70 days of age) and finished in three production systems: pasture, pasture with mother, and pasture with supplementation (soybean hull corresponding to 1% of life weight of the lambs). After slaughter, carcasses were stored in cold chamber, with forced air at 1oC until reaching 24 hours for removal of longissimus dorsi muscle which had been frozen at -18oC for sensory analysis. Meat sensorial characterization was performed by quantitative descriptive analyses: 22 descriptive terms were developed by a team of selected judges who also created the definition for each term and the reference-samples. Acceptability test was performed by using a nine-point hybrid hedonic scale. Meat of male animals and of animals finished in pasture with the mother was characterized by the flavor and softer residual taste sheep meat and fat, less softness and higher chewiness in comparison to the meat of female and of animals finished in the other systems. Meat of lambs finished in pasture systems and pasture with supplementation were similar regarding to sensory aspects. Meat was equally accepted by the consumers, regardless of sex and finishing system, presenting good acceptability.
