Resumo: | This 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. |

Trinta e dois ovinos machos inteiros (20,7 ± 2,63 kg e idade de 8 meses) foram distribuídos em delineamento inteiramente casualizado com 4 intervalos de abastecimento de água via bebedouro (0h00, 24h00, 48h00 e 72h00), com 8 repetições. O aumento do período de restrição hídrica proporcionou redução nos consumos de matéria seca, proteína bruta, fibra em detergente neutro, energia digestível e energia metabilizável (P < 0,05). Os coeficientes de digestibilidade da matéria seca, proteína bruta e fibra em detergente neutro reduziram linearmente (P < 0,05) com o aumento do período de restrição hídrica. A ingestão de água via alimento, a ingestão total de água e a excreção de água pelas fezes apresentaram um aumento linear em resposta ao aumento do intervalo de fornecimento de água (P < 0,05). A ingestão de água via bebedouro, água metabólica, excreção total de água e balanço hídrico apresentaram decréscimo linear, com o aumento do período de restrição hídrica (P < 0,05). O consumo de nitrogênio e o nitrogênio absorvido foram influenciados pela restrição hídrica, apresentando comportamento linear decrescente de acordo com os períodos de abastecimento de água (P < 0,05). O peso final, ganho de peso diário e ganho de peso total, foram influenciados pelos períodos de restrição hídrica, decrescendo linearmente (P < 0.05). A conversão alimentar aumentou com o aumento do período de restrição hídrica (P=0,004). O fornecimento intermitente de água em intervalos de até 72h reduziu a ingestão e a digestibilidade de nutrientes, promovendo diminuição no ganho de peso dos animais estudados.UEL2022-02-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4313210.5433/1679-0359.2022v43n3p1037Semina: Ciências Agrárias; Vol. 43 No. 3 (2022); 1037-1050Semina: Ciências Agrárias; v. 43 n. 3 (2022); 1037-10501679-03591676-546Xreponame:Semina.
