| 摘要: |
| [目的]考察不同添加剂对甘蔗梢叶青贮营养价值的影响,为甘蔗梢叶高饲料化利用提供参考依据。[方法]采用单因素实验法考察尿素、糖蜜、乳酸菌液的添加和三者混合添加对甘蔗梢叶青贮营养价值的影响。[结果]不同的添加剂均能改善甘蔗梢叶青贮的营养品质。当尿素添加量为0.5%(W/W)时最佳,粗蛋白和粗脂肪含量分别提高34.68%和61.27%,半纤维素和中性洗涤纤维(NDF)分别降低10.67%和6.23%,差异极显著(P<0.01);当糖蜜添加量为15%(W/W)时最佳,粗蛋白和粗脂肪含量分别提高20.42%和36.42%,纤维素、NDF和酸性洗涤纤维(ADF)分别降低54.04%,28.30%和45.72%,差异极显著(P<0.01);单独添加乳酸菌对青贮影响不明显,差异不显著(P>0.05);同时添加0.5%(W/W)尿素、15%(W/W)糖蜜和5%(W/W)乳酸菌液青贮效果最佳,粗蛋白和粗脂肪含量分别提高85.92%和69.36%,纤维素、NDF和ADF分别降低38.94%,17.92和33.44%,差异极显著(P<0.01)。[结论]在甘蔗梢叶青贮时,同时添加尿素、糖蜜和乳酸菌,能有效降低其粗纤维含量,提高消化利用率。 |

| Abstract: |
| [Objective] This paper investigated the effects of different additives on the nutritional value of sugarcane tip silage in order to lay a solid foundation for efficient use of sugarcane tip silage.[Methods] The adding amount of urea, molasses, Lactobacillus and their mix on the nutritional value of sugarcane tip silage were examined by means of single factor experiment.[Results] Different additives can improve the nutritional value of sugarcane tip silage.When the best addition amount of urea was 0.5% (W/W), the contents of crude protein (CP)and crude fat (CF)were significantly increased by 34.68%and 61.27%, whereas the contents of hemicellulose (HC)and NDF were significantly decreased by 10.67% and 6.23% (P <0.01);When the best addition amount of molasses was 15% (W/W), the contents of CP and ether extract (EE) were significantly increased by 20.42% and 36.42%, whereas the contents of CP, NDF and ADF were significantly decreasedby 54.04%, 28.30% and 45.72%, respectively (P <0.01).When Lactobacillus was added only, the impact was not obvious (P >0.05);when 0.5% (W/W)urea, 15% (W/W)molasses and 5% (W/W)Lactobacillus were added together, the silage effect was the best, in which the contents of CP and EE were significantly increased by 85.92% and 69.36%, whereas the contents of CP, NDF and ADF were significantly decreased by 38.94%, 17.92% and 33.44%, respectively (P <0.01).[Conclusion] Adding urea, molasses and Lactobacillusin sugarcane tip silage can availably reduce the content of crude fiber and improve digestibility of sugarcane tip. |
