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