Resumo

ABSTRACT: Grape pomace is a by-product that can be ensiled and added to animal feed for a sustainable animal production. This study evaluated the effects of grape pomace silage (GPS) on the intake, performance, and carcass and meat quality of feedlot lambs. Twenty-four male lambs (21.5 ± 3.0 kg initial body weight) were distributed into pairs to four diets levels 0, 10, 20, and 30 % of GPS. The addition of grape pomace silage influenced only ether extract (EE) intake linearly without hindering consumption. The diet did not affect performance and meat quality attributes and carcass parameters, with average daily gain (ADG) of 0.235 kg d−1, feed conversion 4.299, carcass conformation 2.7, compactness index 0.25 kg cm−1, fat thickness 1.51 mm, loin eye area 13.9 cm2, pH 5.79, natural matter moisture 74.05 g 100 g−1, and crude protein (CP) 19.94 g per 100 g−1 of dry matter (DM). Grape pomace as could be used as silage in lamb diets with up to 30 % GPS, as the chemical composition of this by-product and the results indicate that GPS did not compromise performance, carcass traits, and meat quality.
