SUMMARY:

This study evaluated the effect of replacing corn entirely with extra-fat whole corn germ (GIEM) associated or not with forage palm on feed intake, performance, nitrogen balance and blood metabolites of sheep. Forty Santa Inês sheep, males, four months old and with an average initial body weight of 22.17 ± 1.71 kg, were used, distributed in a completely randomized design, in four treatments: ground corn (GC); ground corn + Mexican elephant ear forage palm (Opuntia stricta [Haw]. Haw) (CG+FC); extra-fat whole corn germ (FFCG) and extra-fat whole corn germ + Mexican elephant ear forage palm (Opuntia stricta [Haw]. Haw) (FFCG+FC). The effect of treatments was analyzed by means of orthogonal contrasts. The diet with germ and without forage cactus decreased (P<0.05) dry matter intake, digestibility and nitrogen intake, resulting in lower performance and increased (P<0.05) cholesterol levels. The inclusion of forage cactus provided higher (P<0.05) nutrient intake and digestibility. The inclusion of cactus provided higher hot carcass yields, cold carcass yields and carcass measurements (P<0.05). The diet with germ and without cactus provided lower performance and carcass characteristics and improved the fatty acid profile (P<0.05). The replacement of corn by germ is recommended when associated with forage cactus, since such association has a beneficial effect on nutrient intake, performance, nitrogen balance and blood metabolites, providing better productive responses.
