Fermented Green Vegetable Soybean Meal Increases Dressed Carcass Meat and Bone Weight in Black-Boned Chickens (Fah Luang Chicken, Gallus gallus)

Abstract

To use effectively waste green vegetable soyabean (edamame) and to improve the dressed carcass meat in black-boned chickens (Fah Luang chicken, Gallus gallus), fermented edamame meal was fed to black-boned chickens from 4 to 16 weeks of age. At 4 weeks of age, 20 birds (10 male and 10 female birds) were used to measure the initial weights of dressed carcass meat and each bone part. Another 60 birds were divided into 2 groups with 3 replicates of 10 chickens (5 male and 5 female birds) each. The control group received a basal formula diet only and the experimental group was fed 40 g fermented edamame meal per bird for a period of 30 min before being fed the basal formula diet. The weights of whole body, each dressed carcass muscle part and each bone part increased in the chickens fed fermented edamame meal (p<0.05). The feed cost per Kg body weight gain decreased (p<0.05). Income over feed cost per Kg body weight gain, as well as income over feed cost and strain per bird, increased in the fermented edamame meal group (p<0.05). These facts suggest that the feeding of fermented edamame meal to black-boned chicken induces the chicken’s production due to increase of dressed carcass muscle, cheap feed cost (USD/Kg body weight gain) and high income (USD/bird), suggesting the potential for commercialization of waste edamame meal as a feed ingredient for black-boned chickens.
