A microbial-enhanced protein for juvenile Pacific white shrimp showed higher levels of hydrolysable protein and better digestibility than soybean meal.
Gamma irradiation treatment presents a possible processing technique for reducing anti-nutrients and improving the nutritive quality of many feed ingredients.
With the market volatility of fishmeal, as well as rising sustainability concerns, the aquaculture industry is seeking sources of protein, such as animal byproduct concentrates, to substitute for fishmeal.
Key molecules found in animal byproduct hydrolysates show potential for use as functional ingredients in aquaculture feeds. Animal co-product hydrolysates from slaughterhouse waste and rendered animal byproducts present a protein alternative.
In vitro pH-stat determination of digestibility is a promising technique for quick assessment of nutritional value and potential negative effects.
