چکیده
This study aimed to assess the growth performance and nutritional status of sheep under intermittent water supply by means performance, intake, apparent digestibility nutrients, balance nitrogen. Thirty-two intact male (20.7 ± 2.63 kg, 8 months age) were distributed in a completely randomized design with 4 intervals via drinking trough (0h00, 24h00, 48h00, 72h00), replicates. The extension restriction period caused reduction intake dry matter, crude protein, neutral detergent fiber, digestible energy, metabolizable energy (P < 0.05). coefficients fiber showed linear decrease increasing periods Water food, total excretion feces increase response an interval drinking, metabolic water, presented decrease, Nitrogen absorbed nitrogen influenced restriction, presenting decreasing trend according Final weight, daily weight gain, showing Feed conversion increased as (P=0.004). Intermittent at up 72h00 reduced nutrient digestibility, resulting gain studied animals.
