—Channel catfish Ictalurus punctatus do not feed well at low temperatures. It is generally thought that a diet containing fish meal enhances feed palatability at low temperatures since fish meal is highly palatable to fish. There is a lack of information on the effects of fish meal levels on the growth performance of channel catfish reared at low temperatures. Therefore, a study was conducted i...

Lemna protein concentrate (LPC; 68.0% CP) is produced by extracting protein from de-oiled and dehydrated biomaterials from plants of the Lemnaceae family and may be used as a protein source for animals. There are, however, no published data on the nutritional value of LPC fed to pigs. Three experiments were, therefore, conducted to determine the concentration of ME, the standardized total tract...

To reduce the pressure on aquatic resources due to use of fishmeal in fish feed, mastery and alternative sources all stages development are essential. Five diets including 4 experimental one control diet were considered. Experimental post-larvae developed from unconventional ingredients which was completely replaced by a mixture brewer’s yeast, chicken viscera maggots. These foods tested Claria...

Three basal diets containing 0%, 27.5% and 55.0% solvent-extracted cottonseed meal (CSM) as replacements of 0%, 50% and 100% of solvent-extracted soybean meal (SBM) on an equal nitrogen basis were each supplemented with three levels of iron (40, 336 and 671 mg/kg) from ferrous sulfate heptahydrate (3 3 factorial experiment). Each diet was fed to juvenile channel catfish in triplicate aquaria tw...

The effect of dietary inclusion a mixture microalgae meal (Schizochytrium limacinum and Nannochloropsis oceanica) (1:1 ratio) on growth performance, gene expression, histology muscle fatty acid composition rainbow trout (Oncorhynchus mykiss) reared in saltwater was investigated. Three experimental extruded diets containing 0%, 9% 17% were evaluated triplicate groups during 10-week bioassay. res...

The effect of dietary partial replacement of fish meal (FM) with soybean protein (SP) alone or in combination with lysine (Lys) and methionine (Met) supplementation were tested in a 60-day feeding trial for silvery-black porgy (Sparidentex hasta) juveniles. Seven isoproteic (ca. 50% crude protein) and isoenergetic (ca. 22.4 MJ kg-1) diets were formulated in which 45% (SP45), 60% (SP60) and 75% ...
