Évaluation des apports nutritionnels et énergétiques des fourrages verts dans l’alimentation des aulacodes (Thryonomys swinderianus) en Côte d’Ivoire
Abstract
This research aims to evaluate the physicochemical and energetic quantity of succulent and sweet taste forage grasses, Panicum maximum and Pennisetum purpureum (Poaceae) incorporated in the feed of grasscutters growing (GG), fattening (FG) and maintenance (MG). This study is set to determine the chemical and energetic composition of three levels of green fodder (50, 75 and 85%) incorporated into the diets of grasscutters and compare it to nutrient intake and energy consumption of feed resources used normally in the ration by farmers. The three experimental diets were: 75% fodder and 25% of food complement (diet T25); 50% of fodder and 50% of food complement (diet T50); 85% of fodder and 15% of food complement (diet T15). The results showed that the green fodder used contains important sources of proteins, lipids, carbohydrates and minerals. Dry matter content of Panicum maximum (13.4 to 22.9%) and Pennisetum purpureum (10.9 to 18.6%) provide energy needs as calories needed of grasscutters. Food ingredients consisting of minerals and organic matter provide the energy potential in the form of calories for maintenance and production feed needs of grasscutters. A positive and highly significant effect (p<0.01) of the T15 was observed. These results suggest that the nutritional and energy values consumed can be used for grasscutters growing (GG), fattening (GF) and maintenance (GM).The intake of energy and functional foods into a controlled diet stimulates the appetite of farmed animals. Panicum maximum and Pennisetum purpureum grasses that were used as a substitute for the main staple feed, and which are highly sought after in the natural environment by grasscutters, are recommended for grasscutter raising. Green forages with succulent sweet-tasting stems, incorporated into food rations as 15% of food supplements, are more stable and perform better in food rations for grasscutters. Active nutrients are balanced, varied, moderate and necessary for the proper functioning of the organism of grasscutters.
