Apparent digestibility of feedstuffs by the marine shrimp Penaeus vannamei Boone
The high AAAD for Chitin suggested that the low APD was due to the low digestibility of the amine fraction of the chitin structure and not a low protein digestibility, while alanine had the lowest apparent digestibility value.
Dietary phosphorus requirement of channel catfish.
Data indicates that 0.33% apparent available dietary phosphorus is adequate for maximum growth and bone mineralization in fingerling channel catfish, and it is suggested that a value of 0.4% apparent Available phosphorus be used in formulating catfish feeds.
Effects of Dietary Cottonseed Meal and Gossypol on Growth of Young Channel Catfish
Abstract Ten isonitrogenous and isocaloric diets containing different percentages by weight of cottonseed ineal or gossypol acetate were fed to age-0 channel catfish Ictalurus punctatus for 8 weeks.
The feeding value of soybeans fed to rats, chickens, catfish and dairy cattle is not altered by genetic incorporation of glyphosate tolerance.
These studies support detailed compositional analysis of the GTS seeds, which showed no meaningful differences between the parental and GTS lines in the concentrations of important nutrients and antinutrients.
Comparison of the Channel Catfish, Ictalurus punctatus (NWAC103 Strain) and the Channel × Blue Catfish, I. punctatus × I.furcatus, F1 Hybrid for Growth, Feed Efficiency, Processing Yield, and Body
It is suggested that the CB hybrid possesses superior production traits compared with the NWAC103 channel catfish, however, problems of producing a large number of hybrid fingerlings in a cost-effective manner remain to be resolved before the hybrid catfish can be commercially farmed.
Leucine, isoleucine, valine and histidine requirements of fingerling channel catfish.
Quantitation of serum free amino acid levels revealed a marked increase in valine and isoleucine in leucine-deficient fish, indicating an apparent interaction among these amino acids in the catfish comparable to that previously observed in other species.
Use of Microbial Phytase in Channel Catfish Ictalurus punctatus Diets to Improve Utilization of Phytate Phosphorus
Results from this study demonstrate that microbial phytase is effective in improving bioavailability of phytate phosphorus to channel catfish, which may eventually lead to a reduction in the amount of supplemental phosphorus added to commercial channel cat fish feeds.
Improvement of Cottonseed Meal Protein with Supplemental Lysine in Feeds for Channel Catfish
Two studies were conducted to evaluate cottonseed meal (CSM) with and without supplemental lysine as a substitute for soybean meal (SBM) in catfish feeds, demonstrating that channel catfish can effectively utiliz...
