摘要:
Amylose plays important role in body health. It is controversial whether changing dietary amylose/amylopectin ratio (DAR) will improve meat quality in growing-finishing pigs. A total of 48 Duroc×Landrace×Large White castrated male pigs (initial body weight 49.8±2.8kg) were randomly allotted to two treatments, and fed ad libitum either with a low DAR diet (LR, amylose/amylopectin: 12/88) or a high DAR diet (HR, amylose/amylopectin: 30/70) for 68days. Feed intake was recorded every day, body weight was weighed at 46th and 68th day to calculate...
