Abstract/Summary

Simple Summary: The concept of sustainable diets that are profitable, ethical, socioculturally acceptable, and environmentally beneficial is emerging as one of the key solutions to ensure the efficiency of livestock production systems. In this regard, agro-industrial by-products obtained from fruit processing have emerged as an alternative. Mamey pulp generates residual biomass from which the kernel is the main by-product that, due to its composition, can be used as ruminant feed. This study determined the effects of the inclusion of ground mamey kernel on intake, digestibility, and growth performance in lambs. No effects on nutrient intake or productive performance were observed. However, protein and fiber digestibility were reduced by ground mamey kernel inclusion. These findings suggest that mamey kernels can be included in ruminant diets. Abstract: This study determined the effect of replacing ground corn and soybean meal with ground Pouteria sapota kernel (PSSM) in lamb diets on nutrient intake and digestibility, performance, and carcass traits. Twenty-one male hair sheep lambs with an average body weight of 22 ± 3.5 kg were randomly assigned to three treatment diets containing PSSM at 0, 10, and 20% of the total dry matter (DM) inclusion. The study lasted 60 days, which included 15 days for adaption and 45 days for sample collection. The PSSM inclusion did not affect intake or performance (p > 0.05). However, ether extract (EE) digestibility linearly increased (p < 0.0001), while crude protein (CP) and acid detergent fiber (ADF) linearly decreased. Final body weight, total weight gain, average daily weight gain, feeding efficiency, and carcass traits were not affected by PSSM inclusion. In conclusion, these results suggest that PSSM can replace up to 200 g/kg DM of ground corn and soybean meal without affecting intake or animal performance.
