Key Points

  • To assess the effects of different diets including maize silage and xerophytic plant hays on lamb feed intake, digestibility, and economic viability.
  • Evaluated lambs fed with various diets including maize silage and xerophytic plant hays.
  • Measured intake, digestibility, and slaughter weights over the trial period.
  • Conducted an economic analysis to assess profitability of each diet.
  • Lambs fed on maize silage combined with Gliricidia had higher slaughter weights (31.39 kg) than those on other diets.
  • All diets produced positive profits, with Gliricidia being the most profitable option.
  • Meat color improved with the inclusion of legumes, enhancing overall meat quality.

Abstract

), resulting in greater slaughter weights (31.39 and 29.74 kg). Carcass yield was not affected by the inclusion of xerophytic plant hays. Gliricidia maintained carcass performance similar to SM, whereas SMP and SML resulted in lower carcass weights and commercial cuts. Meat color improved with the inclusion of legumes (SMG and SML). The economic analysis indicated that SM was the most profitable diet, although all diets showed positive profit. Gliricidia is a viable alternative for semiarid production systems, contributing to feed diversification and reducing dependence on maize silage.
