A recent study conducted by Islamic Azad University in Shahrekord, Iran, explored the effects of different zinc sources on the performance, egg quality, and immune system of laying hens at the end of the production period. The experiment involved 520 hens and measured parameters such as body weight, egg weight, and immune response. The study found that zinc supplementation at appropriate levels improved body weight, egg quality, and immune parameters, enhancing the overall performance of the hens. The research concluded that zinc supplementation improves bioavailability, enriches eggs, and mitigates age-related declines in productivity. [Extracted from the article] |
