Abstract: | This study was conducted to assess effects of the benefit microorganisms and enzymes supplementation in diets. A total of 150 Guinea fowls at 5-week old was placed in a completely randomized design with 5 nutritional treatments and 3 replicates, including ten birds per experimental unit. The treatments were supplement levels of 0 (no supplement),0.2% and 0.4% benefit microorganism and 0.4 and 0.8%vitamin-enzyme (VE)to concentrate-basal diets corresponding to the S0, SP0.2, SP0.4, VE0.4 and VE0.8 treatments. The results indicate that the treatments supplemented SP and VE improved final live weight and daily weight gain (p<0.05) and the birds in the PS0.2 treatment had the highest daily weight gain (17.3 g/day), final live weight (1543 g/bird) and better feed conversion ratio (p<0.05). Similarly, the carcass, breast and thigh weights were significantly higher for the SP0.2treatment (p<0.05). The supplement of SP and VE products significantly decreased density of E. coli and C. perfringens in the chicken excreta (p<0.05). It was concluded that the Guinea fowls supplemented SP and VE in concentrate basal diets improved growth rate, carcass performance as well as had better intestinal health and the treatment offered at 0.2% SP gave the highest results. |
