Effect of using green beans processing by-products with and without enzyme supplementation on broilers performance and blood parameters

Abstract The present study was performed to evaluate the possible inclusion of the by-products of green beans (GB) into the diet of broiler chickens. A total number of 288 one day old male Ross broiler chicks were randomly distributed into eight experimental groups. The chicks in the first group were fed a basal diet only and this was the negative control group. The second group served as positive control and the chicks were fed on a basal diet supplemented with a commercial enzyme (Benzyme-A). The six remaining groups were fed diets containing GB at three inclusion levels 8%, 16% and 24% in partial replacement of yellow corn. For each inclusion level one group was fed a diet free of enzyme and the other was fed a diet supplemented with enzyme. The results showed that including GB in broilers diet up to 16% did not significantly affect the chickens’ performance. The recorded blood parameters of the chickens were found to be in normal ranges. The results also revealed that enzyme supplementation enhanced the performance of the chickens. The use of GB in the broilers diet was found to be beneficial from the economic point of view by reducing the total cost of the diet and thus increasing the profit.
