Authors present a practical review of modern formulation options including crystalline amino acids in fulfilling nutritional requirements in aquafeeds.
Este estudio de piedra caliza agrícola de cinco diferentes canteras estadounidenses determinó que las muestras tenían composiciones químicas comparables, pero solubilidades algo diferentes en agua. Este procedimiento podría ser útil para lograr mejores resultados cuando estos productos se usan en
This study of agricultural limestone from five different U.S. quarries determined that the samples had comparable chemical compositions but somewhat different solubilities in water. This procedure might be helpful in achieving better results when these products are used in the
In a 10-week study of nursery-reared Pacific white shrimp performance, the inclusion of Spirulina meal allowed reduction of fishmeal up to 25 percent with no detrimental effect on shrimp growth performance.
A study evaluated Pacific white shrimp given plant protein-based diets with varied lipid content and soybean meal:soy protein concentrate ratios.
Due to its high protein and highly unsaturated fatty acids content, krill meal can be an effective ingredient in aquafeed.
The required level of fishmeal in white shrimp diets can be reduced to 5 percent through substitution as long as fish oil content is kept at 2 percent.
Authors examined whether beta-glucans extracted from bakers yeast could improve the survival and growth of Pacific white shrimp challenged with infectious myonecrosis virus.
A recent study in Brazil tested the efficacy of nine commercial feed attractants for Litopenaeus vannamei. Condensed fish-soluble protein, an amino acid complex with digested bivalve mollusk, and whole squid protein hydrolysate stimulated the highest feeding responses.
A study in Brazil indicated that mutton snappers, a high-value species that readily accepts artificial food, can grow well on diets containing high-quality plant proteins such as soy protein concentrate.
