The poultry industry is always looking for ways to improve efficiency and reduce the cost of production. Most of the attention until now has been on broiler breeder nutrition and research to improve productivity in terms of saleable chicks produced, egg fertility, and hatchability with less focus on how maternal nutrition can positively impact offspring broiler performance. In broiler production, the cost of hatching the egg or a day-old chick is very small compared to the cost in kilograms of a live bird (Callini and Sirri, 2007). These low-cost periods provide opportunities to optimize breeder hen nutrition and management to improve its performance and that of its progeny.
Originally published as "Chapter 10: Harnessing epigenetics to improve chick quality with trace mineral zinc" in the book, Breeder Management & Nutrition: Moving the industry forward, Drs. Juxing Chen and Mercedes Vázquez-Añón explain how trace minerals impact maternal feeding/epigenetics to optimize chick development and health.
