- Abstract
The rabbit breeding is a strategic activity in terms of economic and environmental sustainability. In the current nutritional precision, maximizing the utilization of nutrients is optimized by using additives such as exogenous enzymes. This study evaluated the effect of the use of phytase on growth performance and digestibility in growing rabbits. A total of 40 animals of New Zealand White, assigned to five 2 treatments, with a reference diet and four experimental diets with the addition of 500, 1000, 1500 and 2000 FTU phytase per kilogram of feed. The animals were distributed in a completely randomized design with five treatments and eight repetitions. To study the performance were evaluated: weight at 55 days, weight at 75 days, feed intake, daily weight gain and feed conversion. For the digestibility study, we determined the digestibility of dry matter, mineral matter, organic matter, crude protein, energy and phosphorus. There were no significant differences (P <0.05) for most performance parameters evaluated, improvement was observed only in the feed considering the whole experimental period, where there was an improvement from the inclusion of the enzyme. On the digestibility of nutrients, none of the nutrients was influenced by the addition of different levels of phytase (P> 0.05). Other confirmatory studies should be developed.
