Improvement of Cottonseed Meal Protein with Supplemental Lysine in Feeds for Channel Catfish

摘要: Two studies were conducted to evaluate cottonseed meal (CSM) with and without supplemental lysine as a substitute for soybean (SBM) in catfish feeds. One study was aquaria under controlled environmental conditions fingerling channel catfish, the other fish raised 6-m3 net pens suspended 1.6-ha earthen pond. In each study, solvent extracted CSM substituted SBM on nitrogen basis. Supplemental added feeds which replaced 50 100% of because they estimated be deficient available lysine. aquarium 0, 25, 50, CSM. The same used pen except that 25% substitution not used. Fish fed 4% body weight divided into two equal daily feedings, those station once daily. Data presented herein demonstrate can effectively utiliz...
