Resumo: The aim of this study was to evaluate performance and economic viability of producing sheep fed different levels of roughage, concentrate, and water. Forty Santa Inês crossbred sheep with an average initial weight of 18.85 ± 2.80 kg and an average age of 5.0 ± 2.0 months were distributed in a completely randomized design with a 2 × 2 factorial arrangement composed of two proportions of roughage and concentrate (30:70 and 70:30) and two levels of water supply (ad libitum, and 50% restriction), with 10 replicates. Water restriction had a negative effect (P0.05) feed conversion or feed conversion. Total weight gain, average daily gain, feed conversion, and feed efficiency were influenced by the proportions of roughage and concentrate. In conclusion, the diet with 70% roughage, associated with a water restriction of 50%, reduced the uptake of energy and protein, compromising the animal performance. The combination of the diet plus concentrate and water restricted to 50% of the free consumption provides a better cost-benefit ratio.

Utilizaram-se 40 ovinos mestiços de Santa Inês, não castrados, com peso inicial de 18,85 ± 2,80 kg e idade média de 5,0 ± 2,0 meses, distribuídos em um delineamento inteiramente casualizado, em um esquema fatorial 2 x 2, composto por duas proporções volumoso e concentrado: 30:70 e 70:30 e duas ofertas de água (água à vontade e restrito em 50%) com 10 repetições. A restrição de água causou efeito negativo (P0,05) da restrição de água na conversão e eficiência alimentar. O ganho de peso total, ganho médio diário, conversão e eficiência alimentar foram influenciados pelas proporções de volumoso e concentrado. Concluiu-se que a dieta com 70% de volumoso e associada a uma restrição hídrica de 50%, reduz o aporte de energia e proteína, desfavorecendo o desempenho animal. A combinação da dieta com mais concentrado e restrição hídrica de 50% do consumo permite melhor relação custo benefício.UEL2016-06-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2174310.5433/1679-0359.2016v37n3p1595Semina: Ciências Agrárias; Vol. 37 No. 3 (2016); 1595-1606Semina: Ciências Agrárias; v. 37 n. 3 (2016); 1595-16061679-03591676-546Xreponame:Semina.
