The aim of this study was to study the effects of different levels of guar meal (GM) on growth performance of meat ducks, to explore the possibility of GM as an alternative protein resource in meat duck diets. Firstly, the chemical composition, dry matter (DM) digestibility, metabolic energy (ME) were determined. Secondly, a total of four hundred eighty 15-day-old Shuanggui-tou meat ducks were divided into 4 treatments, 1) Control group (0% GM in the diet), 2) 3% GM group (3% GM in the diet), 3) 6% GM group (6% GM in the diet), and 4) 9% GM group (9% GM in the diet).
