Desempenho e características quantitativas dos componentes não carcaça de cordeiros mantidos em confinamento alimentados com inclusão de torta de girassol

Abstract

The objective was to evaluate the performance and yield of non-carcass components of lambs finished in feedlot receiving lambs formulated with sunflower cake inclusion. A total of 28 crossbred Suffolk lambs, not castrated, with an average weight of 21 kg, distributed without design in randomized blocks with four diets and seven replications were used. Soybean diets provided were provided from a basic diet (soybean treatment – T1) where corn and energy control sources come. Other treatments were included in the sunflower cake at levels of 10%(T2), 20%(T3) and 30%(T4) replacing part of the corn and soybean components of the basic diet so that the 4 treatments were isoproteic, with 17% protein. The animals on the diet were in confinement for an average period of 60 to 160 days, in a confinement regime, where the first 30 days were for adaptation. Daily weight gain (BW) variables were: days of confinement, slaughter weight (PA), slaughter weight (GPT), average daily weight (ADW), water per daily weight (DMG), carcass weight ( ) and coldness (PCF), length of the housing (CC) and its internal length (CCI). After beating and bleeding, all non-carcass constituents (heart, lungs+trachea, spleen, hig+vesicle, rinse, diaphragm, penis, testes, rumen + reticulum, omasum + abomasum, small intestine and large intestine, skin, head, limb boundaries and adipose deposits: omentum and renal fat) were separated and separated. By the alterations, it was followed to increase that the BP increased, GPT, increased, increased, increased, increased, increasing, as they increased, increasing, as the diets increased, increasing, as the diets increased. aforementioned diets. In general, the contents of the gastrointestinal tract (GIT) decreased linearly with the use of sunflower cake. Thus, the inclusion of increasing levels of sunflower cake in the diet of lambs influenced performance and affected the development of structures of non-carcass components. The type of diet has an influence on the proportions of the organs responsible for nutrient intake and absorption. The components that add value to production are not contradictory components, in order to promote value and the realization of more value for their use and comprehensive to the necessary use systems and comprehensive to the necessary use systems.
