Protein in aquafeeds:A major cost cftod how to handle it

摘要

Protein is a major cost in aquafeed as aquatic animals have high protein needs compared to terrestrial animals. Furthermore, fishmeal is very often used in fish and shrimp diets. Its price increases faster than other ingredients. Over a 25 years period, fishmeal price increased by 350 percent, while soybean increased only by 150 percent (Source: Indexmundi). In this situation, feed producers need to be careful when using protein sources to fulfil the needs of the animals. Indeed, protein itself doesn't mean a lot, it could have a low digestibility (because of intrinsic composition of an ingredient, or suffer from processing for eg), it could also be unbalanced. This could result in lower growth of the animal. This brief article will help you save some cost on your feed while safeguarding its quality.
