The production period is a continuation of the preparation period. Once production period starts, the design of the feeding programme should be based on the nutrient demand (mg / bird / day; kcal / bird / day) to meet the requirements for maintenance, growth, and reproduction. The nutritional recommendations included in this guide are aimed at obtaining the highest percentage of hatchable eggs with a weight between 58–62 g, as referenced in production standards. Again, the uniformity of the flock will play a fundamental role. Environmental conditions, stocking density, health status etc, may require you to modify the nutritional profile. Since production is affected by energy, protein/amino acid levels, and body weight, it is recommended to regularly monitor parent stock weight, along with parameters such as feed and water intake, egg weight, and egg number during the laying period. The effects of poor preparation later in life cannot be corrected through management and nutrition.
