Evaluación de una dieta biológicamente activada en la alimentación de conejos

Abstract

In the Animal Biotechnological and Microbiological Laboratory of the Faculty of Cattle Sciences and in the Minor Species Program in the Training Center of Guaslan of MAGAP, three levels of microbial preparation (100 ml.kgˉ¹, 200 ml.kgˉ¹ y 300 ml.kgˉ¹) were evaluated considering a witness in day-by-day concentrated diet for new Zealander rabbits at 10 times of repetition per treatment, distributed by a design of blocks at random with a bi-factorial combinatory setting. The best productive indicators are reached with 200 ml.kgˉ¹ of microbial preparation (T2), with final weight of 3379,60g; consume of food of 7467,43 g MS and alimentary conversion of 3,98; analysis of interaction showed that microbial preparation gives better results in females because they reached a final weight of 3494 g , weight gaining of 2155,40 g and alimentary conversion of 3,74 besides, the presence of Escherichia coli was eliminated in applying this microbial preparation benefiting animal health. It was also demonstrated the implantation of microbial lactic acid in the small intestine as well as the microbial preparation levels are increased getting a final worth of 4224000 UFC.mlˉ¹ with 300 ml.kgˉ¹ food level. According to the economics analysis a profitability of 35% in female and 33% in male was obtained, so it is recommended use 200 ml.kgˉ¹of microbial preparation in the day-by- day concentrated diets for rabbits
