裹包层数对甜高粱青贮饲料品质的影响

Effects of Wrapping Layers on the Quality of Baled Sweet Sorghum Silage

为研究裹包层数对甜高粱(Sorghum saccharatum Moench)青贮饲料青贮品质的影响。分别采用4层、6层、8层及12层裹包处理含水率为65%~70%的甜高粱,评价贮藏期干物质含量、粗蛋白、粗脂肪、NDF、ADF、半纤维素以及感官品质的变化。结果表明:6层裹包层数基本能实现甜高粱青贮饲料长期良好的贮藏。

The effects of different wrapping layers（4,6,8and 12）on the quality of baled sweet sorghum silage were studied.In the experiment,we used sweet sorghum（moisture content 65%~70%）as experimental material and evaluated the changes of dry matter,crude protein,ether extract,NDF,ADF,hemicellulose and sensory quality in baled sweet sorghum silage.The results showed that 6layers of wrapping guaranteed the quality of sweet sorghum silage in a good level.
