Evaluación de diferentes niveles de harina de cabezas de camarón en la alimentación de conejos neozelandés en las etapas de crecimiento - engorde

Abstract

The use of different shrimp head meal levels (4, 8, y 12 %) was evaluated in the New Zealand rabbits on Research Unit on Minor Species in the of Animal Sciences Faculty, to be compared with a control treatment, 64 animals of 60 days of age were used, and a completely randomized desing (DCA) was applied, in combinatorial arrangement with two factors. The best results regarding the final weight variable, weight gain and feed conversion the best values were reported with the use of 12 %, while for the variable performance to the carcass, the best values were obtained with the use of 4, 8 and 12 %. When analyzing the sex factor of the animal no statistical differences were found, except in the variable weight to the carcass reporting the best value in females when using 12 % in relation to males. The highest profitability of 20 % was obtained with the inclusion of 12 % shrimp head meal, reaching a profit/cost of the 1.20. The use of shrimp head meal positively influenced the productive behavior of rabbits. Therefore, the use of 12 % of shrimp head meal is recommended because the best production parameters, lower cost of production and better benefit/cost of feeding rabbits were recorded in the growth-fattening stages.
