Elaboración de un ensilaje biológicamente acelerado a partir de vísceras de Tilapia (Oreochromis mossambicus) para alimentación animal.

Abstract

The present investigation was carried out with the objective of elaborating a biologically accelerated silage from viscera of tilapia (Oreochromis mossambicus) for animal feed. Three formulations were produced with 3 replicas of silage with the tilapia visceras in Pscícola Cordero de Fancisco de Orellana, with F1 being the best low-artisan formulation, which consisted of: 600 g of viscera, 100 mL of molasses, 47.5 mL of inoculum, 250 g of wheat bran and 2.5 g of ascorbic acid. F1 contains 19.69% protein and 6.12% fiber which is important for the chicken to lose weight and increase muscle mass; F1 presented 29.98% of fats, this is beneficial to avoid oxidative rancidity, F1 did not present pathogenic microorganisms Salmonella sp in 25g. Subsequently, the silage was elaborated on a semi-industrial scale the quantities used as: viscera of tilapia 48% Kg mixture 8 liters, inoculum 4 liters, wheat bran 20K., ascorbic acid 200 gr. the compact mixture was made the same as a completely hermetic plastic bag was placed and it was in a plastic container of 125 liters, during a period of 50 days, at room temperature of 27.5 C (Francisco de Orellana), and finally, the field test was carried out, the administrative ration for 15 days was 6 kg of the diets 90-10%, obtaining a 56.6% of consumption, and 43.33% of waste; while with the other diet 80-20% concentrate-silage ; a lesser amount of waste was evidenced 26.6%; clear indicative that broiler chickens were more inclined by this diet, accepting 4.4 Kg of dietary supplement, the diets were applied in the sixth and seventh week. It is recommended to carry out tests with the biological silage accelerated in diets for other zootechnical species.
