The protein and fiber content of tropical forages does not affect its preference by fattening rabbits

Abstract

The objective of this research was to evaluate the preference for forages commonly used in animal feed in tropical areas of Mexico. Forages of Guasimo (Guazuma ulmifolia), Cocohite (Gliricidia sepium), Swirl grass (Paspalum notatum), Egypt grass (Brachiaria mutica), and Humidicola grass (Brachiaria humidicola) were offered simultaneously to 24 New Zealand rabbits for 14 days. In this investigation it was shown that Gliricidia sepium and Brachiaria mutica were preferred compared to Guazuma ulmifolia, Paspalum notatum and Brachiaria humidicola (P <0.05) The consumption of crude protein, acid detergent fiber, and neutral detergent fiber were higher with Gliricidia sepium and Brachiaria mutica (P <0.05). In conclusion, fattening rabbits preferred Gliricidia septum, and Nutrient content was not related to consumption preference. Forage preference study and its relationship with nutritional content are necessary to include tropical resources in rabbit feeding.
