Abstract

This study evaluated the effects of incorporating different levels of corn dried distiller grains with solubles (DDGS) with or without NSPase enzyme supplementation in broiler diets on growth performance, carcass traits, digestibility, and economic efficiency. A total of 240 one-day-old (Avian 48) broiler chicks were randomly divided into eight groups, each containing 30 chicks (3 replicates of 10 chicks). Experimental diets were iso-caloric and iso-nitrogenous and included 0%, 5%, 10%, and 20% DDGS, with or without NSPase enzyme. The inclusion of Smart NSPase® enzyme significantly enhanced body weight (BW) and feed conversion ratio (FCR) (p ≤ 0.05), particularly at moderate DDGS levels. Group G2 (0% DDGS + enzymes) achieved the highest BW, followed by G4 (5% DDGS + enzymes) and G6 (10% DDGS + enzymes). High DDGS levels (20%) without enzymes negatively impacted growth. Up to 5 and 10% DDGS inclusion without enzymes showed comparable performance to the control, but enzyme supplementation further optimized growth and nutrient utilization. Carcass traits, including yield and dressing percentages, showed no significant differences (p ≤ 0.05) among most groups, although high DDGS levels without enzymes reduced breast meat weight. Economic feed efficiency (EFE) was highest in diets with 5% DDGS + enzymes among DDGS-fed groups. The study concluded that among DDGS-fed groups, the 5% DDGS with enzyme supplementation showed the best economic returns, achieving (137.72%) relative to the control. Incorporating up to 5 and 10% DDGS with enzyme supplementation is a sustainable alternative to traditional broiler diets, enhancing growth, nutrient absorption, and economic returns.
