Feed is the major input cost when it comes to poultry production and can account for up to 70% of total production costs in certain parts of the world. With soybean meal prices at a high level, the cost of including proteins/amino acids in feed ingredients continues to increase. Due to raw material scarcity and high cost, producers have learned to balance costs by using a variety of raw material sources available locally. Animal producers taking advantage of lower-cost alternative protein sources may discover these ingredients are not as readily absorbed or digested, leading to diminished performance compared with corn-soy diets. With dietary proteins not completely utilized by the animal, there is potential to improve amino acid utilization by effectively utilizing the alternative raw materials and supplementing animal diets with proteolytic enzymes.
