Different Dietary Levels of Protein to Lipid Ratio Affected Digestive Efficiency, Skeletal Growth, and Muscle Protein in Rainbow Trout Families
Torrissen, Krisna Rungruangsak; Stien, Lars Helge; Daae, Britt S.; Vågseth, Tone; Thorsheim, Grethe B.; Tobin, Declan; Ritola, Ossi (Journal article; Peer reviewed, 2009)Normal Protein (NP) and High Protein (HP) diets were provided to rainbow trout families from juvenile to maturity. Muscle protein concentration increased during growth and the protein to lipid (P/L) ratio was doubled at ... -
