不同切碎长度对胡萝卜苗青贮品质的影响

Effects of Different Chopping Length on the Quality of Carrot Silage

试验以收获期的胡萝卜苗为原料,研究不同切碎长度对胡萝卜苗青贮品质的影响。分别设置切碎长度为2、4 cm的两组进行青贮,青贮后进行取样分析,并通过感官评定、p H、氨态氮、干物质、粗蛋白质、中性洗涤纤维、酸性洗涤纤维和粗灰分等指标来评价青贮品质。结果表明,不同切碎长度对胡萝卜苗青贮品质有一定的影响,并且切碎长度较短的胡萝卜苗青贮饲料品质优于切碎长度较长的胡萝卜苗青贮饲料。

To study the effect of different chopping length on the quality of carrot silage,the research used carrots at the harvest time as experimental material. Two groups of carrots were ensiled with different chopping length 2cm and 4 cm,after that,taken sample analysis between the two groups. Evaluated quality of carrot silage by sensory evaluation,p H,ammonia nitrogen contents,dry matter,crude protein,neutral detergent fiber,acid detergent fiber and Ash content. The results showed that different chopping length do have an influence on the quality of carrot silage,as well as the quality of carrot silage with shorter chopping length was better than the other one.
