• Resumen

  • In the humid tropics of Mexico, sheep production is an important economic activity, mainly focused on the sale of barbacoa and barbacoa tacos; however, no primal cuts of lambs are offered. Objective: To assess carcass yield and primal cuts of lambs fed on different diets in Loma Bonita, Oaxaca, Mexico. Design/Methodology/Approach: Five diets were assessed to measure carcass yield and primal lamb cuts: corn stover, corn silage, Chinese hibiscus (locally known as tulipán), cracked corn, and grazing. A completely randomized experimental design was used. The following variables were measured: hot and cold carcass weight, hot and cold carcass yield, neck weight, leg weight, shoulder weight, loin weight, rib weight, rib eye area determination, and fat thickness. Results: Lambs fed on cracked corn achieved a higher carcass yield (44.2%) than the other treatments (P≤0.05), a leg weight of 3.87 kg, and loins 2.57 kg heavier than the other treatments, in average (P≤0.05). Study Limitations/Implications: It was difficult to obtain homogeneous groups of lambs in terms of age and weight. Findings/Conclusions: Lambs fed on cracked corn recorded higher carcass yields and better leg and loin primal cuts than lambs fed on the other diets.
