Guide to Poultry Feed | Ingredients, Nutrients, and Formulation Explained

Poultry feed ingredients are selected based on their nutrient content, absence of anti-nutritional or toxic factors, palatability, and cost. The key nutrients provided by these ingredients include amino acids, vitamins, and minerals. Additionally, energy is a crucial component obtained from starches, lipids, and proteins. 

This article provides an in-depth look at the different types of poultry feed ingredients, their nutritional profiles, and the process of formulating poultry feeds.

What do Chickens Eat?

Chickens require a well-balanced diet to maintain optimal health, which should be rich in protein and lower in carbohydrates. Their diet can be composed of various feed types, but essential ingredients typically include cracked corn, cereals, fats and oils, protein meals, tubers, roots, vitamins, and minerals. To further enhance their nutrition, you can introduce healthy treats, but these should constitute no more than 20% of their total feed intake.

Their nutritional needs may vary with the seasons. During the winter, it's beneficial to provide a high-carbohydrate diet to help them maintain energy levels, as carbohydrates serve as a great energy source. In contrast, during the summer, when feed is more readily available and the chickens are less active, you should focus on providing a feed higher in protein (18% or more). Organic and grower feeds can also be excellent options for meeting their dietary needs throughout the year.

Types of Feed Ingredients

Poultry feed ingredients are broadly classified into cereal grains, protein meals, fats and oils, minerals, vitamins, and miscellaneous raw materials such as roots and tubers. Understanding these categories is essential for formulating a balanced and nutritious diet for poultry.

1. Cereal Grains

Cereal grains are primarily used to meet the energy requirements of poultry. The dominant feed grain is corn, but different grains are used in various regions depending on availability and cost. For instance, corn is the primary energy source in the US, Brazil, and most Asian countries, while wheat is more prevalent in Europe, Canada, Australia, New Zealand, and the Russian Federation. In certain regions, such as parts of the US and China, wheat may replace corn if it is more economically viable.

Cereal grains and their by-products, such as wheat bran and rice bran, are used widely in poultry feed. Cereal by-products are high in fiber, which is less digestible for poultry and provides lower metabolizable energy (ME). Seasonal and storage conditions affect the quality of cereal grains, with poor conditions potentially leading to reduced energy content or contamination with mycotoxins.
