Resumo: Com o objetivo de identificar e caracterizar a composição das proteínas miofibrilares (miosina, actina e ?-actina) do músculo Longíssimos dorsi refrigerados e sem refrigeração de cordeiros submetidos à diferentes níveis de proteína bruta na ração (12, 15, 18 e 21%), foi conduzido um trabalho com 24 amostras do referido músculo que foram ainda divididas em duas partes, assim de cada amostra utilizouse um pedaço que foi resfriado por 24 horas e outro por 7 dias da carne de Ovinos submetidos a diferentes níveis de proteína na dieta. Não foram encontradas diferenças significativas quanto ao conteúdo das maiores proteínas do tecido muscular de ovinos, relacionados ao nível de proteína da ração
nem quanto aos tempos de resfriamento.

Abstract: With the aim of identifying and characterizing the composition of the Myofibrillar proteins (myosin, actin and ? ? actin) of refrigerated and no refrigerated muscle Longissimus dorsi of lambs submitted to different levels of raw protein in the ration (12, 15, 18 and 21%), this work was ran with 24 samples of the referred muscle were removed and these were still divided in two parts, so, it was used a piece from each sample which was freezed for 24 hours and another one for seven days from the ovine meat submitted to different level of protein in the diets. No significative difference about the content of the biggest proteins of the ovine muscle tissue related to the level of ration protein nor to the refrigeration
time were found.

The dynamic model presented in the current paper estimates heat production and heat flow between growing and mature cattle (Bos indicus and Bos taurus) and the surrounding environment. Heat production was calculated using the NRC (2000) and heat flows between the animal and the environment were based largely on existing models and physical principles. Heat flows among the body core, the skin, the coat and the environment were calculated. Heat flows from and to the environment included solar radiation, long wave radiation, convection and evaporative heat loss. Physiological responses of cattle (sweating, panting and vasodilation) were modelled through mechanistic equations. The model required weather (radiation, temperature, wind and vapour pressure), animal (body-core weight and genotype-specific parameters) and dietary inputs (dry matter intake rates and diet composition) and estimated heat balance and the physiological responses of the animal to within-day weather variation. The current paper has focused on heat stress, although the model was designed to run under both hot and cold climatic conditions. The model developed in the current paper provides researchers and livestock producers with the ability to predict heat stress and to evaluate mitigating procedures. |
