In this experiment, the piglets weaned at 7 days of age were used, and the aim was to determine the effect which hydrolyzed wheat gluten (HWG) replacing different doses of whey protein concentrate (WPC) in artificial milks on growth performance, nutrient metabolism, immune function and antioxidant capacity of piglets. Forty-five healthy crossbred (Duroc×Landrace×Yorkshire) piglets at 7 days of age were randomly allotted into four treatments, including control group (n=15), 33%HWG group (n=10), 66%HWG group (n=10), and 100%HWG group (n=10), which were fed the artificial milks that HWG replaced 0%, 33%, 66% and 100% WPC for 13 days, respectively. The results showed that HWG replacing WPC in artificial milks could affect growth performance, nitrogen metabolism, lipid metabolism, kidney function, immune function and antioxidant capacity in piglets. Compared with the piglets of control group, HWG replacing 66% and 100% WPC significantly reduced average daily feed intake and average daily gain (P<0.05), significantly enhanced feed to gain ratio and diarrhea index (P<0.05), significantly decreased serum creatinine (P<0.05), and significantly increased serum malondialdehyde concentrations (P<0.05) in piglets. In addition, serum immunoglobulin A and M levels were significantly reduced (P<0.05) when 66% of WPC was replaced by HWG, and serum high density lipoprotein cholesterol levels were significantly increased (P<0.05) when 100% of WPC was replaced by HWG. Compared with the piglets of control group, serum urea and high density lipoprotein cholesterol levels were significantly higher in the piglets fed the artificial milk that HWG replaced 33% WPC (P<0.05). In summary, HWG replacing different doses of WPC in artificial milks might be not conducive to growth performance, nutrient metabolism, immune function and antioxidant capacity in the early-weaned piglets, but when HWG replacing 33% WPC in artificial milks had not significantly negative effect on piglets.
