Effect of Wheat Straw and Different Additives on Silage Quality and In vitro Dry Matter Digestibility of Wet Orange Pulp

摘要

This study was carried out to investigate effect of no additives (control) or 10% wheat straw, 10% wheat straw+0.5% urea, 10% wheat straw+5% molasses, 10% wheat straw+5% wheat grain, 10% wheat straw+0.5% urea+5% molasses and 10% wheat straw+0.5% urea+5% wheat grain (weight basis) on silage quality and in vitro dry matter digestibility of wet orange pulp. Contents of dry matter, crude protein, ADF, NDF, pH values In vitro dry matter digestibilities and fleig points of wet orange pulp were in range of 14.62-22.26, 7.62-14.17, 30.97-41.46, 51.02-56.22, 3.60-4.13, 51.58-80.62 and 81.85-101.73%, respectively (p<0.05). As a result, wet orange pulp can be ensiled well with or without additives, but addition 10% of wheat straw would be benificial to eliminate negative effects related with the high moisture content of wet orange puple.
