Dietary l-arginine supplementation alleviates immunosuppression induced by cyclophosphamide in weaned pigs

A study was conducted to investigate the effects of l -arginine (Arg) on performance and immune function in cyclophosphamide (CY) immunosuppressed weaned pigs. The weaned pigs were allotted randomly into one of three treatments, including: (1) non-challenged control; (2) CY-challenged group; and (3)...
