A guide to Layer Poultry Feed Formula.
For layer feed formula, you need to understand the following important things:
(a) nutrient requirements of the class of poultry (e.g., egg layers, meat chickens or breeders);
(b) feed ingredients in terms of nutrient composition and constraints in terms of nutrition and processing, and
(c) cost and availability of the ingredients.
Most large-scale rooster farmers have their personal nutritionists and feed mills, while small operations generally depend upon representative nutritionists and business feed turbines for their feeds. It is therefore critical that formulations are correct because once feeds are formulated and manufactured, it is frequently too overdue to treatment any mistakes or inaccuracies without incurring widespread expenses.
