Balanço hídrico em Ovinos Santa Inês submetidos a dietas com diferentes proporções de feno com Capim Buffel (Cenchrus ciliaris l.) e Jurema Preta (Mimosa tenuiflora wild).

Abstract

Water balance in sheep Santa Ines submitted to with diets of different proportions of hays buffel grass (cenchrus ciliaris l.)and black jurema (mimosa tenuiflora wild). This study aimed to evaluate the water balance of Santa Inês sheep fed different proportions of hay Buffel grass and Jurema Preta. We used 12 Santa Ines sheep, kept in individual metabolic cages for 14 days for adaptation and 5 days of experiment. The experimental diet was provided twice a day, at 8:00 h and 16:00 h, which was composed of 40% concentrate and 60% forage base of buffel grass hay and / or jurema preta. Was recorded daily weights of food and water offered and leftovers in order to calculate the intake of water. Buckets were used to collect feces and urine, for further evaluation of dry matter. The results of water intake by Santa Ines sheep, there was a quadratic effect (P <0.05) replacing buffel grass hay by the jurema preta for all variables. There was no effect (P> 0.05) substitution of hay in any variable referring water excretion. The amount of water absorbed in grams presented quadratically as was the replacement of hay buffel jurema preta the hay. In terms of water retention there was no effect of treatments.
