Abstract

Apparent digestibility coefficients (ADCs) of crude protein (CP), lipid, phosphorus, essential amino acids (EAA), non-essential amino acids (NEAA) and fatty acids were determined for white shrimp (Litopenaeus vannamei). One type of traditional Chinese medicine (TCM) comprising a mixture of equal proportions of six herbs and plant materials was used at 0, 0.5, 1.0, 2.0, 4.0 and 8.0 g kg−1 in the six experimental diets. ADCs were determined using 0.01% Y2O3 as an indicator. A total of 450 shrimp (initial mean body weight 8.6±0.5 g) were randomly stocked into 18 500 l outdoor concrete tanks. Feces were collected from three replicate groups of shrimp.ADCs of six diets were: CP, 88.39–91.30%; lipid, 61.63–74.36%; phosphorus, 45.38–47.29%; EAA, 90.37–93.28%; NEAA, 89.73–92.10%; saturated fatty acids (SFA), 54.35–66.03%; monounsaturated fatty acids (MUFA), 61.36–77.56%; and polyunsaturated fatty acids (PUFA)+highly unsaturated fatty acids (HUFA), 61.33–85.20%. ADCs of CP decreased as TCM increased. However, ADCs of lipid and phosphorus increased as TCM increased except for the diet containing TCM 8.0 g kg−1. AA and fatty acids availability values for test diets followed a similar trend to values of CP and lipid.
