The Requirements of Chickens for Nutritional Compounds for Growth, An advanced Nutritional outlook

The science of nutrition includes the provision of balanced nutrients that meet the need of chickens (animal) to grow, maintain and continue production, and for economic reasons, these foodstuffs should be at the lowest prices, so we should provide these materials only with what the nutritional requirements need without a significant increase. However, we must provide some nutrients at higher levels in practical situations, in order to try to meet the shortage of some food components The costs of feeding chickens represent 60-70% of the total expenses in poultry projects, so the nutritionist's goal is to obtain the highest production at the lowest possible costs while making use of feed materials whenever possible. And the nutritionist must form a relationship in which all the nutrients that the bird needs are available, whether for the production of meat, table eggs or hatching eggs. In this review, we will review the basics of feeding poultry birds, the most commonly used feed materials, the nutritional needs of each bird according to its type, age, production status, how to form leeches and models of leeches that can be used, as well as diseases caused by a lack of various nutrients.
