This study evaluated the effect of feeding juvenile L. vannamei several times a day versus two and four times – manually or with an automatic feeder – with a low-fishmeal diet supplemented with crystalline amino acids.

Prof. Boyd discusses the overall conversion efficiency of plant protein to animal protein (including pasture animals), which been estimated at 8.3 percent globally. The whole animal conversion for feed-based production is around 35 percent for chickens, 20 percent for swine, and 10 percent for beef.
Intelligence
Oysters provide important, natural filtration of water and are an important component of many healthy coastal ecosystems because their active filtering can help improve and maintain water quality. For many coastal communities, oysters are an important food resource and excellent sources of protein and amino acids, zinc, selenium, iron and B-vitamins.
Health & Welfare
Determining dietary requirements for tilapia requires precise formulation. Individual amino acids must be considered to establish well-balanced diets.
Responsibility
Improved feeds and feeding practices increase the proportion of nitrogen recovered in fish and shrimp and lessen the amount of ammonia excreted by the culture animals.
Health & Welfare
Catfish feeds used in trials at LSU were formulated to possess an amino acid balance similar to that of the channel catfish body.
