Feed proteins are essential nutrients included in animal rations to support growth, health, and productivity. Plants (e.g., soybean meal, canola) and animal by-products (e.g., fish meal, meat and bone meal) are commonly used protein sources today. However, alternative protein sources such as insects, algae, or microbial proteins have gained popularity in recent years, particularly due to sustainability concerns. All these protein ingredients provide the essential amino acids required for the vital biological functions of livestock, poultry, and aquatic species.
There are many reasons for adding protein to animal feed. The primary reason, as mentioned above, is to provide amino acids, which are the building blocks of body tissues such as muscles, organs, and enzymes. Certain amino acids play a critical role in maintaining a healthy immune system and help animals build resistance to diseases. Additionally, sufficient protein intake increases weight gain, milk yield, egg production, and feed conversion efficiency, and supports fertility and embryonic development. Young and growing animals, as well as lactating or laying animals, require higher protein levels to sustain their growth and production. In ruminants, protein also helps maintain microbial activity in the rumen, which is essential for efficient digestion.
In summary, proteins are vital ingredients of nutrition in animals, just as they are in humans, and contribute to animals’ health, productivity, and sustainable food production.
