Utilización de zingiber officinale (Jengibre) como promotor de crecimiento en la alimentación de conejos de raza neozelandéz en la etapa de crecimiento- engorde

Abstract

In the Minor Species Program, Of the Facultad de Ciencias Pecuarias at the ESPOCH, the use of three levels of ginger (700, 800, 900 mg) was evaluated, in feeding of New Zealand rabbits, during the growth and fattening stage for checking with a control treatment. It was used 40 rabbits 20 females and 20 males with an initial weight of 1.18 kg. A completely random design was applied with a combinatorial arrangement of two factors, where factor A was the levels of ginger, and factor B the sex of animals. The results registered highly significance differences (P< 0.01), by effect of the treatment for the weight, forage consumption, weight, forage consumption, concentrate consumption, total food consumption, weight to the carcass and performance to the carcass variables, there were no significant differences (P> 0.001). Regarding the sex factor, the variables that presented significant differences (P< 0.05), they were the weight to the carcass and performance to the carcass, with, males being more predominate that the female. The best cost benefit indicator was obtained in treatments with 800 and 900 mg of ginger, a profitability of 1.13 for both treatment was obtained. Since the ginger´s effect at the level of the digestive system of rabbits acts at the level of intestinal microvilli. Finally, it is recommended to add in the feeding of rabbits, during the stage of growth and fettering, 900 mg of ginger for each kilogram of concentrate, since in this investigation it was presented better values in the variables studied.
