SUMMARY In short-term studies, organic sources of supplemental zinc in broiler breeder hen diets have produced inconsistent results regarding reproductive performance and immune status. Furthermore, there are limited data addressing the long-term effects of dietary zinc source on broiler breeder hen performance. This study examined reproductive and immune responses of caged broiler breeder hens provided diets supplemented with 160 ppm zinc from either ZnSO4 (control), AvailaZn zinc-amino acid complex (ZnAA), or a mixture of ZnAA and ZnSO4 (80 ppm zinc from each) from hatching to 65 wk of age. Egg specific gravity, settable egg production, and estimated chick production were optimized when hens were provided diets that were supplemented with zinc from a mixture of ZnAA and ZnSO4. Immune response to phytohemagglutinin-P and antibody titers to Newcastle disease virus were increased with birds given diets supplemented with 160 ppm zinc from ZnAA. Generally, supplementing diets with a combination of ZnAA and ZnSO4 resulted in superior reproductive performance of caged broiler breeder hens, while supplementing with ZnAA enhanced immune status of hens.

• Influence of Some Dietary Organic Mineral Supplementations on Broiler Performance (2009, unknown): “Hudson et al. (2004) indicated that broiler breeder hens provided diets supplemented with zinc from ZnAA might have increased thymulin activity; therefore, enhancing immune responses through increased maturation of T lymphocytes and activation of B lymphocytes by T-helper cells.”
• Zinc in Broiler Feeding and Nutrition (2008, background): “Hudson et al. (2004b) indicated that the specific gravity of egg, setting egg production, and chick production per hen were significantly increased when broiler breeder hens were provided with zinc from a mixture of ZnAA and ZnSO4.”
