Rendimentos dos não constituintes de carcaça de caprinos e ovinos e custos de produção de pratos regionais

Abstract

The non-constituent components of the carcass are a potential source of additional income for producers in the semi-arid region of Brazil, and may account for a large percentage of the profits in the production system as a result of their commercialization. The objective of this study was to evaluate the relationship between the non-carcass components (NCC), live body weight at slaughter and empty body weight, to characterize the lambs and goats NCC biologically and economically, as well as to evaluate their commercialization in the form of typical dishes. Were used 32 sheep and 32 goats, being 16 males and 16 females of each species, kept up to 70 and 100 days old. The animals were weighed, slaughtered, eviscerated and the carcass, the empty body weight and the weight of the non-carcass constituents were obtained. The NCC were used to assemble Kits for making delicacies according to species and age, forming 3 Kits for each animal species, with two ages. An analysis of the economical viability of the commercialization of the non-carcass components was made. The experimental data were analyzed in a 2×2×2 factorial scheme, in a completely randomized design using Analysis of Variance and the means were compared using the t test (P<0.05). Developments were made in the existing interactions. The non-constituent components of the carcass represent a high yield relative to the carcass of the animal, with differences between species, ages and sex. The NCC external were heavier in sheep (3,084 kg) and in animals with 70 days (15.93%), as were vital organs (2.61% and 2.88%, respectively). There was a difference in total fat, where goats and females presented greater fat, mainly due to the accumulation of renal and pelvic fat. With the sale of animals, the NCC should also be considered, since they generate a minimum return of R$ 15.86 for each slaughtered animal, with the oldest slaughtered animals (100 days) presenting a larger increase in income due to the higher viscera yield. The Kits formed with more items generate greater economic return by the greater use of organs. The use of NCC of goats and sheep is an economically viable alternative, since it incorporates in the income products that represent a good part of the income of the animal.
