Abstract

The aim of this study was to determine the effects of guar germ supplemented with compound enzymes on nutrient, amino acid and energy utilization rates of Linwu ducks. Twenty-four healthy adult male Linwu ducks with body weight of about 2.0 kg were randomly divided into 3 groups with 8 replicates in each group and 1 duck in each replicate. Metabolic tests were carried out by hunger strike-gavage method. Ducks in group 1 and 2 were fed 60 g/d diet by gavage, diet of the group 2 was added with 250 mg/kg compound enzymes, and ducks in group 3 were fed 60 g/d diet with no nitrogen by gavage. The apparent utilization rate, true utilization rate, apparent metabolic energy (AME) and true metabolic energy (TME) of dry matter (DM), crude protein (CP), ether extract (EE), crude fiber (CF) and 17 kinds of amino acids of guar germ supplemented with compound enzymes for Linwu ducks were determined. The results showed that the true utilization rates of DM, CP, EE and CF of guar germ were 67.07%, 67.57%, 65.52%, 82.88% and 77.39%, respectively. The AME and TME were 11.34 and 13.31 MJ/kg, respectively. The true utilization rates of 17 kinds of amino acids were 67.72% to 93.70%. Adding with compound enzymes, the true utilization rates of DM, CP, EE, CF and energy increased by 5.23%, 8.02%, 5.80%, 3.66% and 3.31%, respectively (P > 0.05). AME and TME increased by 3.97% and 3.27%, respectively (P > 0.05). The true utilization rates of 17 kinds of amino acids increased by 1.73% to 11.62%, and the true utilization rates of serine, glycine, leucine, tyrosine and phenylalanine were significantly increased (P < 0.05). The results indicate that guar germ supplemented with compound enzymes containing protease and non-starch polysaccharide enzyme can improve utilization rates of nutrient, acid contents and energy of Linwu ducks.
