Abstract

The experiment was carried out to evaluate the pigeon pea in the feeding of free range pullets. A metabolism assay was carried through using the method of total excreta collection and one of performance. In the metabolism assay 160 pullets from ‘pesadão’ line with 21 days old were used. The birds were distributed at random into two treatments with eight repetitions of ten birds. The treatments consisted of a diet-reference and a diet-test (60% of diet-reference and 40% of ground raw pigeon pea). The values of crude protein, ether extract, crude fiber, dry matter, crude energy and apparent metabolizable energy corrected to nitrogen retention were: 25.03%; 1.13%; 5.95%; 89.83%; 3823Kcal/kg and 1795 Kcal/kg, respectively. In the performance assay 525 pullets from ‘pesadão’ line with 30 days old were used. The birds were distributed into five treatments with five repetitions of 21 birds each one. The treatments consisted of inclusion of ground raw pigeon pea (GRPP) in the diets, which were: 5%, 10%, 15%, and 20%, being the control treatment without inclusion of pigeon pea. The inclusion of 20% of pigeon pea presented the best gain weight (1170.93g) and feed conversion (2.19 g) in period 1 ( 35 to 56 days), being that in the total period the inclusion of 10, 15 and 20% presented the best feed conversions (2.69; 2.73 and 2.68 kg) respectively. However, the feed consumption, yield of carcass, cuts, abdominal fat and pancreas weight were not influenced significantly by the inclusion of the GRPP in the diet. The inclusion of 20% of pigeon pea in the diet improves the weight gain and the feed conversion in the period from 35 to 56 days. However, the inclusion of 10, 15 and 20% improves the feed conversion in the total period; it may be a satisfactory alternative in the creation of free range broiler.
