Popis: | This study evaluated the substitution of fish meal with tilapia protein hydrolyzate (TPH) in diets for Silver catfish (Rhamdia quelen) by verifying the effects on growth, body composition, blood and biochemical parameters, and biomarkers of oxidative stress. Five isoproteic and isoenergetic diets (37% crude protein, 3,800 kcal/kg) were produced with different substitution levels of TPH (0%, 5%, 10%, 15% and 20%) for fishmeal. The hydrolyzate was obtained by enzymatic hydrolysis from carcasses of Nile tilapia (Oreochromis niloticus), which were exposed to swine pepsin enzyme at 36°C for four hours. The experimental design was completely randomised with five treatments and four replications. The inclusion of 20% TPH in diets for silver catfish increased the growth of Silver catfish juveniles. At levels above 5%, there was an increase in body protein deposition and the efficiency of oxidative metabolism. |
