“…O peso/rendimento da carcaça é determinado pela taxa de crescimento, que, por sua vez, varia segundo o grupo genético, o sexo, a idade, a condição fisiológica e a nutrição (PAULA et al, 2017). Para que a produção ovina ocorre de forma mais precoce possível, visando proporcionar ao animal máximo rendimento de carcaça, é importante um manejo alimentar racional, adequado e economicamente viável (ESTEVES et al, 2018;MACIEL et al, 2015).…”

Apesar da comercialização de ovinos se basear na observação do peso dos animais, é necessário o conhecimento da composição percentual dos cortes e de outras partes que compõem o peso dos animais e que caracterizam a qualidade do produto. Os distintos cortes que compõem a carcaça possuem diferentes valores econômicos e sua proporção constitui importante índice para avaliação da qualidade comercial da carcaça. Dessa forma, o rendimento dos diferentes cortes comerciais da carcaça é parâmetro importante para direcionar sistemas de alimentação que venham obter cordeiros jovens em terminação. O confinamento é uma estratégia utilizada pelos pecuaristas, visando o abate de animais precoces, com produção de carcaças de melhor qualidade, permitindo obter um melhor preço pelo produto. Objetivou-se fazer um levantamento das características de carcaça e componentes não carcáceos de ovinos.

“…The increased amount of BGS in the diet reduced true carcass yield. Leg and loin have the highest commercial values and are thus 'prime' or 'first-class' cuts, given the relatively high proportion of muscle and tenderness (Esteves et al, 2018). However, in this experiment relative amounts of the various cuts were unaffected.…”

The aim of the study was to evaluate the carcass characteristics, proximate composition, and sensorial attributes of meat from sheep fed diets in which buffelgrass silage replaced corn silage. Thirty-two intact male crossbred Santa Inês sheep with an average live weight of 20.09 ± 2.0 kg were housed in individual stalls and allotted at random to four treatments in which corn silage was replaced by buffelgrass silage at the levels of 0 (control), 33.3%, 66.6%, and 100%. After an adaption period of 10 days, the sheep were fed for an additional 61 days. Feed was offered ad libitum and corn silage comprised 60% of the diet for the control group. Carcass characteristics, non-carcass components and meat quality were evaluated. Hot carcass yield, cold carcass yield, true carcass yield, trimmings, fat weight, and mesenteric and omental fat weight were highest for the control group (P <0.05). Loin eye area had a quadratic response (P =0.02), with the largest areas being observed in animals fed the diet containing 66.6% buffelgrass silage. Liver weight (P <0.01), luminosity of the meat (P <0.05), and cooking loss (P <0.05) likewise had nonlinear responses to the concentration of buffelgrass silage in the diet. The treatments did not have significant negative influence on the nutritional and organoleptic characteristics of the meat.

“…The head, foot, and skin growth are affected by the animal's age, weight, race, and gender. Esteves et al (2018) working with Santa Ines hair ewes aged 6 to 48 months, observed that younger animals had higher leg yield. As age increases, the commercial cuts number has decreased and the loss of quality characteristics has increased.…”

The objective of this work was to evaluate the yields, morphometric measures, carcass, and non-carcass components, and carcass regional and tissue composition of an indigenous sheep (Pantaneiro) of different physiological stages (gender, age, system production. Thirty sheep, eleven lambs, nine wethers, and ten cull ewes were used. The lambs were finished in feedlots, the wethers were maintained on pastures and supplementation, and the cull ewes were maintained on an extensive pasture system with mineral salt ad libitum. Slaughter ages were defined to simulate the most representative products and farming systems. Animals were slaughtered and classified as non- castrated lambs, wethers, and cull ewes. The criteria to slaughter lambs and wethers were the body condition, which ranged from 2.5 to 3.0. Cull ewes were slaughtered based on negative pregnancy diagnosis, regardless of their body condition, which ranged from 4.0 to 4.5. All animals were slaughtered after 16-hours of fasting (solids). The ewes presented the greatest fat thickness, differing significantly from the lambs. The morphometric measures were higher in ewes and lambs. The muscle to fat ratio of the animal’s cuts from different physiological stages presented no significant differences. The indigenous Pantaneiro sheep have good potential for meat production regardless of their physiological stages. The ewes stood out, presenting carcasses with good performance considering their potential and longer permanence in the herd due to their reproductive function.
