Abstract

Zinc (Zn) malnutrition poses a major threat to broiler farming in terms of poor growth andperformance of chickens. The current study utilized zinc sulfate (ZnSO4) to treat Zn deficiency in Cobb broilers. Four treatments were formed comprising of ten 21-dayold broilers/treatment. The broilers were fed a Zn enriched diet from week 4 to week 6, as per the treatments established with respect to the National Research Council (NRC) recommendation -0, 10, 20 and 40 ppm. The growth parameters of broilers were evaluated on d 21, 28, 35, and 42, while the organ weights of the slaughtered birds were examined on d 42. The weekly growth performance of the broiler chickens in the current study exhibited significantly highest (p<0.05) live-bird weight (LBW), weight gain (WG) and average daily feed intake (ADFI) but significantly lowest (p<0.05) weight gain percentage (WGP) and feed conversion ratio (FCR) in week 6. Furthermore, the average values for the 21-day rearing period indicated that Zn supplementation in poultry feed significantly affected the ADFI of the poultry birds, resulting in the highest valuein the case of T2. However, the total weekly feed intake (TWFI) inversely related to the Zn doses. The increasing Zn doses (40 and 20 ppm) were associated with a significant increasein WG and WGP. Additionally, dietary Zn enrichment resulted in significantly greater feed utilization efficiency for T3 and T2. Overall, T3 revealed the significantly highest (p<0.05) WG, WGP and LBW, along withthe lowest (p<0.05) FCR at the conclusion of the chicken growth period which was an indication of improved growth parameters using Zn. Moreover, organ weights of the broilers exhibited non-significant (p>0.05) differences after Zn addition in the basal feed. Therefore, the present findings suggested that 40 ppm Zn dose resulted in better growth and performance of the broilers which correspondedto the integral role of Zn in the physiological performance of the body.
