VITAMINS and MINERALS in POULTRY, Prof. Dr. Ergin Öztürk, Editör, İksad Yayınevi, Ankara, ss.131-168, 2024
This document examines the vitamin and mineral requirements of breeding laying hens, focusing on their influence on reproduction, health, and offspring performance. It provides a detailed analysis of key vitamins (A, D, E, and C) and minerals such as calcium, phosphorus, selenium, and zinc, highlighting their roles in poultry nutrition. Vitamin A supports reproductive health, egg production, and immune function but requires careful dosing to avoid toxicity. Vitamin D is essential for eggshell quality and calcium absorption, impacting bone health and laying efficiency. Vitamin E enhances immune responses, reduces oxidative stress, and improves fertility and sperm quality, while vitamin C helps mitigate environmental stress but is not always essential due to poultry’s ability to synthesize it. Minerals play a critical role in various physiological processes. Calcium and phosphorus are vital for bone health and eggshell strength, requiring precise Ca/P ratios for metabolic balance. Selenium boosts antioxidant defenses, reproductive health, and offspring growth, with organic forms showing superior effectiveness. Zinc is essential for eggshell development and immune response, with organic sources offering better bioavailability. The document emphasizes the need for tailored diets incorporating bioavailable and organic nutrients to optimize health and productivity. It underlines the importance of modern supplementation strategies that consider environmental stressors, genetic advancements, and production demands in meeting the nutritional needs of breeding laying hens.
