Abstract
- Feeding represents the core business in fish production, therefore, digestibility was evaluated by a principle of additivity of enzymatic hydrolyzates from animal origin in White Cachama (Piaractus brachypomus) as a nutritional alternative. For this purpose, we used a control diet and three mixtures. In the case of mixtures, 30 % of the control diet was replaced by hydrolyzed chicken, pork and trout viscera respectively; which were supplied to 120 juveniles of white Cachama with an average weight of 145,40 ± 3,17 g, fish were distributed by means of a complete randomized design (DCA) in 12 conical cylinder tanks and were collected for stool by sedimentation to determine the digestibility of nutrients, energy and mineral absorption. Significant differences (p<0,05) were presented for the apparent digestibility of crude protein, crude energy, crude fiber, absorption of ash, calcium, phosphorus and digestible energy according to the type of enzymatic hydrolyzates evaluated and in relation to the control diet. The results showed that the hydrolyzates have a high nutritional value because the digestibility of nutrients and energy were greater than 80 %. Therefore, enzymatic hydrolyzates from animal viscera are a protein and energy alternative in fish feed. [ABSTRACT FROM AUTHOR]
