Utilização da torta de palmiste na alimentação de frango de crescimento lento

Abstract

The higher costs on poultry are with food. The resulting by-product palm kerael cake of almond oil extraction (Elaeis guineensis) emerges as a viable altemative both from the nutritional standpoint as economical. Objective to evaluate the effect of the inclusion of Palm pie in chicken feed of slow growth in the growth phase and final, on the growth performance, carcass yield and serum biochemical profile: glucose, total triglycerides and total cholesterol. 264 birds was used with 29 days of age, initial average weight 773 grams, male, lineage Label Rouge, distributed in completely randomized design with four treatments and six replications of 11 birds. The treatments consisted in inclusion 0, 10, 15 and 20% of palm kemel cake for growth phase (29 to 63 days) and 0, 15, 20 and 25% of palm kemel cake to final round (64 to 83 days). For evaluation of blood components glucose, triglycerides and total cholesterol totais were collected blood from the ulnar vein of the wing of the bird to 35, 50, 65 and 80 days of age. We evaluated the average weight, average weight gain, feed intake, feed conversion and viability in cumulative periods (29 to 63 days) and (64 to 83 days) and the income of casting and parts (chest, back, thigh, wing, drumstick, head neck and feet) and of the organs (heart, gizzard, liver and abdominal fat) to 84 days of age. The data were subjected to analysis of variance and the significant treatments (P < 0.05) suffered polynomial linear regression, in addition to carrying out the comparisons between the basal diet and treatments, and the Pearson correlation coefficient between variables of performance. There was no effect of palm kemel cake on the relative weight of gizzard showing positive behavior (P <0,05). For glucose and triglycerides totais there was significant difference (P <0,05), but total cholesterol leveis did not show this difference in phases studied. It is concluded that the palm kemel cake could be used at leveis of 20% and 25% in feed for growth and end of broilers, respectively. The research found that the parameters of growth performance and carcass yield were not affected, and the serum biochemical profile does not exceed leveis of references for healthy birds.
