The impacts of dietary protein on growth, body proximate composition, feed utilization, amino acid profile, digestive enzyme activity and amino acid metabolizing enzymes in soft‐shelled turtles (Pelodiscus sinensis) (initial weight: 4.02 ± 0.06 g) were measured during an 8‐week feeding trail. Six diets containing 8%, 18%, 28%, 38%, 48% and 60% (control group) fishmeal were formulated, which contained...
The aim of this study was to investigate effects of dietary feed additives on growth and immunological status of Litopenaeus vannamei under cold exposure. Four experimental diets with 0.2% taurine, 0.01% carnitine, 0.1% cholesterol supplementation and control were fed to L. vannamei (IBW 0.86 ± 0.03 g) for 30 days at 30 ± 1°C before water temperature was dropped to 16°C with a rate of −4°C h−1. Growth...
