Synergistic Effects of Zinc-DETA, Zinc-Fulvic Acid, and Soya Lecithin on Growth Performance, Immunity and Antioxidant Status in Broiler Chickens: A Comparative Study

Lavleen Kumar Gupta* and Y Adinarayana Reddy

This study evaluated the comparative effects of different zinc sources and combinations, including Zinc Sulfate (ZnSO4), Zinc-DETA complex, Zinc-Fulvic Acid complex, and their synergistic combination with and without soya lecithin, on the growth performance, immune response, antioxidant status, and zinc retention in broilers. A total of 300 Cobb 430 broiler chicks were divided into five treatment groups: T1 (ZnSO4), T2 (Zn-DETA), T3 (Zn-Fulvic Acid), T4 (Zn-DETA + Zn-Fulvic Acid), and T5 (Zn-DETA + Zn-Fulvic Acid + Soya Lecithin). Over a 42-day trial, Parameters assessed included body weight gain, Feed Conversion Ratio (FCR), Newcastle disease vaccine titer, Superoxide Dismutase (SOD), Catalase (CAT) activity, zinc retention, and mortality were assessed. The combined treatment (T5) showed superior outcomes across all parameters, suggesting that the inclusion of soya lecithin with zinc chelates and fulvic acid significantly enhanced bioavailability and efficacy.
