Resumo: The objective of this experiment was to evaluate the effect of 2 feeding systems and 5 breeding groups on the growth performance, biometric features, and stomach morphology of feedlot goat kids. The experiment utilized gender as a randomized blocking factor in a 5 × 2 factorial scheme. The study goats were from the Alpine, Anglo-Nubian, 1/2 Boer x Alpine, 3/4 Boer x Alpine, and 7/8 Boer x Alpine breeds. Half of the goats were fed an experimental diet, whereas the other half were given the same diet supplemented with 1.5 L milk daily. The kids were slaughtered after they attained 30 kg body weight. The 1/2 Boer x Alpine goats showed superior growth performance because they exhibiting considerable heterosis. These animals are especially easy to use given that there is no need to maintain cross-bred females (½ Boer x Alpine e ¾ Boer x Alpine) in the flock. Using milk in the feed the animals does not adversely affect growth performance or biometric features. Moreover, it helps to reduce the total weight of the stomach and leads to a 51.39% savings on feed. Dietary supplementation of milk in goat feed is recommended so long as there is excess milk available on the property.

Foi utilizado o delineamento em blocos (gênero) casualizados em esquema fatorial 5 x 2, sendo os grupos raciais: Alpino (A), Anglo-Nubiano (AN), 1/2 Boer x 1/2 Alpino (1/2BA), 3/4 Boer x Alpino (3/4BA) e 7/8 Boer x Alpino (7/8BA), submetidos a dois sistemas alimentares: 1,5 L de leite/animal/dia mais dieta experimental ou apenas dieta experimental sem fornecimento de leite. Os cabritos foram abatidos após atingirem 30 kg de peso corporal. Os animais 1/2BA foram os que apresentaram melhor desempenho, devido à manutenção de maior heterose nesse cruzamento e que implica em facilidade de manejo por não haver necessidade de manter fêmeas cruzadas 1/2 Boer x Alpine e 3/4 Boer x Alpine no rebanho. A utilização de leite na alimentação dos animais não traz prejuízos ao desempenho e medidas biométricas, e ajuda a reduzir o peso total do estômago, propiciando economia de 51,39 % no consumo da dieta, podendo ser recomendado caso haja leite excedente na propriedade.UEL2016-08-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa de campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2129910.5433/1679-0359.2016v37n4p2111Semina: Ciências Agrárias; Vol. 37 No. 4 (2016); 2111-2122Semina: Ciências Agrárias; v. 37 n. 4 (2016); 2111-21221679-03591676-546Xreponame:Semina.
