BUGARIN-PRADO, Job et al. Effect of supplementation with avocado meal on lamb diets on growth and carcass performance. Abanico vet [online]. 2021, vol.11, e121.  Epub 04-Abr-2022. ISSN 2448-6132.  https://doi.org/10.21929/abavet2021.32.

To evaluate the inclusion of avocado meal (AM) in diets for sheep (0, 2.5, 5 and 10%) with a forage:concentrate 40:60 ratio, on productive behavior and carcass characteristics. Ninety-six Pelibuey- Dorper male lambs with an average initial weight of 32.83 ±0.707 kg, 8 animals per treatment, in a 4x3 four diets and factorial arrangement with feeding periods of 28, 56 and 84 days were used. Final weight and slaughter weight increased (p <0.05) with 10% inclusion compared to the control. In daily weight gain, feed intake, carcass weight and intramuscular fat, values were equal (p >0.05) with the inclusion of 10% AM and 0% AM. Feed conversion, DM, CP, energy and carcass performance efficiencies did not improved with AM. The longer the intake time (56 and 84 days), the higher the daily weight gain, feed intake, feed efficiency of DM, CP and energy (p < 0.05), and the lower the feed conversion rate, with no differences for final weight and carcass performance (p < 0.05). Daily gain and carcass weight indicate a slight positive trend due to the inclusion of 10% AM at 84 days. Inclusion does not affect the productive behavior of growth in sheep. Keywords: avocado meal, growth performance, carcass, sheep.
