ASHOUR, E.A. et al. Impacts of dietary inclusion of dried brewers' grains on growth, carcass traits, meat quality, nutrient digestibility and blood biochemical indices of broilers. S. Afr. j. anim. sci. [online]. 2019, vol.49, n.3, pp.573-584. ISSN 2221-4062.

The current investigation aimed to evaluate the effect of dietary inclusion of dried brewers' grains (DBG) on growth performance, carcass traits, meat quality, nutrient digestibility, blood biochemical constituents and antioxidant indices of broiler chickens. A total of 300 unsexed one-week-old Hubbard chicks were randomly allotted to five treatment groups. The dietary treatments consisted of a basal diet as the control and DBG groups (3%, 6%, 9% and 12%, respectively). The best feed conversion ratio (FCR) was found in the group of birds fed a diet containing 9% DBG, compared the other groups. Dressing and abdominal fat percentages decreased significantly but gradually with the elevated DBG level in the diets from 6% to 12%. The inclusion of DBG in broiler diets resulted in significant positive effects on all of the sensory evaluation indicators except appearance and tenderness. Broilers fed a diet containing 3% DBG had significant higher of digestion coefficients for crude protein than those fed on the other experimental diets. Based on growth performance and health status, 3% or 9% DBG may be the optimum percentages for inclusion in the diets of poultry until six weeks old. In addition, DBG exerted several health benefits in meat, which would be reflected positively on human health.
