Características de carcaças de frangos de corte alimentados com resíduo do maracujá

Abstract

Brazilian poultry production reached a significant spot on the world stage, the country was considered the second largest producer of chicken meat in the year 2016. However, even though it is seen as an activity that has grown in the country, the high cost of initial investment, especially for the acquisition of inputs, has made researchers look for alternatives that become viable for production, which guarantees satisfactory levels of bird performance and that make the activity profitable. Thus, the objective of this study was to evaluate the inclusion of passion fruit seed in the feeding of broilers from 1 to 42 days of age on carcass yield, noble cuts and edible viscera. A total of 200 one-day-old male broilers from the Cobb commercial line were used in a completely randomized experimental design with five treatments of inclusion of the passion fruit residue, four replicates and ten chickens per experimental unit. The experiment was conducted at the Experimental Aviary of the Agricultural Sciences Center of the Federal University of Alagoas (UFAL), located in the city of Rio Largo, under the approval of the Ethics Committee on the Use of Animals– CEUA/UFAL (Parecer n° 60/2017). At 42 days of age, the birds were fasted for six hours, weighed and identified. They were then harrowed, slaughtered and eviscerated for analysis of the carcass, noble cuts and edible viscera. The evaluated parameters were: absolute (g) and relative weights (%) of carcass, noble cuts and edible viscera. According to the results, the passion fruit residue can be included in up to 16% in the diet of broilers up to 42 days, without compromising the carcass yield, noble cuts and edible viscera.
