Nutritional supplementation with non-conventional food resources and its effect on the productive parameters in rabbits

Résumé 0

The effect of diets with nonconventional forage resources, balu (Erythrina edulis) and giant taro (Alocasia macrorrhiza) was evaluated, on production parameters of New Zealand white rabbits (Oryctolagus cuniculus) under family farming production, in Silvania (Cundinamarca, Colombia). 36 weaned rabbits of 35 days old were used. They were distributed in 4 treatments (substitution of commercial pellets by giant taro leaves flour 25% (Giant taro), balu 25% (Balu); their mixture, giant taro 12.5% and balu 12.5% (GB), and a control with commercial pellets) with three repetitions each. Variables evaluated: initial weight at 35 days old, daily weight gain, consumption, feed conversion and final weight at 85 days old, carcass yield, haunch, loin and meat. Data was analyzed by Tukey multiple comparison test at 5% significance level, variance homogeneity and error independence verified by means of Shapiro-Wilks, Levene and Durbin-Watson tests, respectively by R program. No significant differences were found in the final weight, on weeks 5 and 6, which registered significant differences (p
