Twenty four 7-day-old crossbred goslings (Chuan white×Tai lake) were divided randomly into control and treatment groups. Enzyme preparation was added in the diet of treatment group at dosage of 1 g/kg. The blood samples were collected from 60 day-old goslings via the wing vein. During the fifty-three days experiment, body weights were adopted measured each week, related hormone contents and biochemical parameters in plasma were determined. The results were as following:(1) Compared with control, body weight of treatment group were significantly higher (P<0.05) since 3-week-old goslings. The weight gains were significant higher (P<0.05) in 4~7 week-old goslings too, feed intake were increased and the “feed: body weight gain” was decreased; (2) Compared with control, growth hormone (GH) and insulin-like growth factor-I (IGF-I) levels were dramatically enhanced by 36.62 % (P<0.01) and 66.55 % (P<0.01) respectively, while the level of β-endorphin (β-END) decreased by 51.66 % (P<0.01); (3) Thyroid-stimulating hormone (TSH) and 3,3\
