Replacing corn meal by butternut squash flour in broiler chickens nutrition
A total of 144, Cobb Avian 48, genetic line broilers, reared up to 42 days of age were distributed in a split plot experimental design with 4 treatments and 3 replicates, each formed by 12 chickens, 6 of each sex, in order to evaluate the substitution of corn at 0, 50, 75 y 100% by integral pumpkin flour (HIZ), as an alternative energy, protein and natural pigments source in the performance of the birds during the growing and finishing phases. The best results were obtained with the ration 50% replacement, which compared with other rations with inclusions of HIZ, got the highest averages in live weight, carcass weight, feed conversion and efficiency, without significant differences (p<0.05) to control treatment in carcass yield, but high differences in the low abdominal fat content and high grade on skin pigmentation, resulting benefited both aspects with the treatment 50% HIZ included. It valued to according to the regression of the growth curve of the birds that will have been required only 3 to 5 days more of chick placement to reach the commercial weight.
