Uso da vagem da faveira (Parkia platycephala) na inclusão da dieta de aves da raça Canela-Preta

Abstract

The use of regional ingredients as alternative feeds can benefit the farming of native breeds. The objective of this study was to evaluate the of different levels of faveira pod meal (Parkia platycephala) inclusion in the diet of Canela-Preta chickens from 15 to 63 days of age, aiming to determine its impact on zootechnical performance. The experiment, approved by the animal ethics committee under protocol number 025340/2023-15, was conducted at the Nucleus for the Conservation of Native Chickens of the Middle North (NUGAN) at UESPI, using 60 birds with an initial body weight of 78.17 ± 0.17 g, distributed in a completely randomized design with five treatments and four replicates. The diets, based on corn and soybean meal, contained 0%, 3%, 6%, 9%, and 12% inclusion of faveira pod meal. The animals were weighed weekly to evaluate feed intake, weight gain, and feed conversion ratio. The data were subjected to analysis of variance, and the means were compared by Tukey's test at 5% probability. A significant effect (P < 0.05) was observed in weight gain at 56 days, with the 3% level showing the highest average weight (111.5 g). The adjusted regression equation indicated a maximum inclusion point of 2.55% of faveira pod meal. The 12% inclusion resulted in a significant reduction in weight gain. Thus, it is recommended to use up to 3% inclusion of faveira pod meal in the basal diet of Canela-Preta chickens without compromising performance.
