Efecto de la utilización de industores de crecimiento en el manejo de conejos neozalandés

Abstract

In the neighborhood of Rosario in the Chambo Cantón, located eight kilometers from the city of Riobamba, Chimborazo Province, an evaluation was carried out to test growth inducers (Zeramec and Boldemec) against a control (lvermectina) in the management of New Zealand rabbits. The sample consisted of 48 rabbits, 24 females and 24 males with an approximate age of 60 days and an average weight of 805 g, distributed under a completely randomized design (CRD), in combinatorial array of two factors, where A was growth inducers and B sex. Eight repetitions were carried out. Experimental results that were obtained were subjected to analysis of variance, mean separation and Tukey test at 0,05 and 0,01 of significance, the best production results were obtained with Zeramec (TI), reaching a final weight (3,68 kg); weight gain (2,87 kg) with efficient feed conversion points of 3,97; 1,85 kg carcass weight, carcass yield of 52,26% and the lowest cost/kg weight gain (2,38 USD). In regards to the factor of sex, females they outnumbered males in final weight (3,41 kg) weight gain (2,60 kg) carcass weight (1,78), carcass yield (51,95%) and lower conversions and cost/kg of weight gain of 4,35 points and 2,61 USD respectively. The highest profitability was determined with the application of Zeramec with females making a profit/cost ratio of 1,31.
