Efecto de la achira (Canna edulis) sobre el consumo voluntario y la digestibilidad aparente de nutrientes en cuyes (Cavia porcellus) en la etapa de engorde

Abstract

The objective of this inquiry was to evaluate the effect of ingestion of the diets based on achira flour on the productive behavior, voluntary consumption and apparent digestibility of nutrients the guinea pig. This research was carried out in the Faculty of Agricultural Sciences - UTA. Twenty-eight male guinea pigs, of 8 weeks old were used, randomly distributed in four experimental diets: T1 with 0% of achira flour, T2 with 8% of achira flour, T3 with 16% of achira flour, T4 with 24% of Achira flour. Voluntary intake of nutrients from diets was evaluated; weight gain; Feed conversion and apparent nutrient digestibility. Voluntary intake of nutrients showed no difference between treatments for the following nutrients: dry matter (P = 0.0570) with 62.670 g / day in T2 being the highest value among treatments; Organic matter (P = 0.0377) for T2 with 64.933 g / day; Neutral detergent fiber (P = 0.0214) for T2 with 24,440 g / day and acid detergent fiber (P = 0.0346) for T2 11.6583 g / day. While for crude protein showed differences (P = <.0001) between treatments being the highest consumption for T2 (17.4567 g / day). Weight gain and feed conversion were better in T2 treatment with 12,607 g / day and 5.04. In the apparent digestibility, there was no difference between treatments for the following nutrients: dry matter (P = 0.7145) with 73.650 g / day in the T1 being its highest value between treatments; Organic matter (P = 0.8032) for T1 with 71.023g / day; Neutral detergent fiber (P = 0.4125) for T1 with 49.100 g / day and acid detergent fiber (P = 0.3217) for T1 39,057 g / day. While for protein (P = 0.9625) the highest consumption is for T2 with 70,295 g / day.
