Comportamento ingestivo e digestibilidade de dietas para Veado-catingueiro consumindo diferentes volumosos

Abstract

Between July and August of 2005 nine brown brocket deer (Mazama gouazoubira), were housed in individual stalls, and submitted to three treatment containing three repetitions, with the objective of evaluating the consumption and the digestibility of alfalfa (Medicago sativa), mulberry leaves (Morus Alba) and perennial soybean (Neonotonia Wightii), as well as the ingestive behavior of the animals in relation to the diets the one that was submitted, being monitored for 24 hours, in regular intervals of five minutes, being determined the feeding activities, rumination, water consumption, leisure and other activities. There was significant difference (P < 0,05) in the natural matter consumption; however, when an adjustment for dry matter, the difference did not persist. It was observed differentiates (P < 0,05) in the times of ingestion, rumination, leisure and other activities. The animals that consumed mulberry leaves spent more time ingesting, ruminating and in leisure than the animals that consumed the other foods and for that they spent less time with other activities. There was not influence (P > 0,05) of the food type on the tax of mastication of the animals. There was significant difference (P < 0,01) in the coefficients of digestibility of the dry matter and of the fractions of the fiber (P < 0,05). Was ended that the consumption of matter drought did not differ among the treatments, although the animals that consumed mulberry leaves have spent more time in the ingestion and rumination of that food, suggesting possible inherent differences to the cellular wall of this bulky one interfering in these varied. The brown brocket deer used in this study, they were shown relatively efficient in the digestion of the fiber, when this was used as partial ingredient of the diet, and the animals that consumed mulberry leaves and perennial soybean, obtained the largest digestibility coefficients.
