Abstract

本发明公开了一种降低水牛胃肠道甲烷产生的饲料配方。本发明饲料以风干物质为基础，质量百分数配方如下：玉米25.0％～27.0％，豆粕7.5％～11.25％，啤酒渣3.75％～7.5％，青贮玉米25.0％～27.0％，象草22.5％～26.25％，发酵木薯渣2.0％～7.5％，碳酸氢钠1.0％～3.0％。本发明通过粗饲料的科学搭配来降低奶水牛胃肠道甲烷产生。与其它方法不同的是本发明未添加甲烷抑制剂类添加剂，而是通过纯天然饲料配合的途径来降低反刍动物胃肠道甲烷排放量。

Description

一种降低水牛胃肠道甲烷产生的饲料配方
技术领域
本发明属于反刍动物饲料配方，具体是一种降低水牛胃肠道甲烷产生的饲料配方。
背景技术
全球气候升温，2009年12月丹麦哥本哈根会议的召开让人们更加深刻地了解了气候变化现象的严重性，形成了控制温室气体排放的政治共识，也引起科学家们对温室气体之一甲烷排放量的关注，而反刍动物瘤胃发酵所产生的甲烷约占人为甲烷总产量的23％，占全球甲烷总排放量的15％。目前，降低反刍动物胃肠道甲烷排放的营养途径多是通过甲烷抑制剂，这些抑制剂对瘤胃内环境微生物有抑制作用，抑制甲烷菌的同时也抑制了纤维降解菌等对反刍动物消化代谢有益的微生物的生长，因此通过纯天然饲料的途径来降低反刍动物胃肠道甲烷排放量的实际意义更大。
发明内容
本发明的目的是提供一种应用发酵木薯渣和啤酒渣配制一种降低水牛胃肠道甲烷产生量的饲料配方。
本发明解决上述技术问题的技术方案如下。
1.一种降低水牛胃肠道甲烷产生的饲料配方，以风干物质为基础，降低奶水牛胃肠道甲烷产生的饲料的质量百分数配方如下：玉米25.0％～27.0％，豆粕7.5％～11.25％，啤酒渣3.75％～7.5％，青贮玉米25.0％～27.0％，象草22.5％～26.25％，发酵木薯渣2.0％～7.5％，碳酸氢钠1.0％～3.0％。
本发明与其他方法不同的是，应用了广西亚热带作物副产物发酵木薯渣2.0％～7.5％和啤酒渣3.75％～7.5％作为粗料原料来降低水牛胃肠道甲烷的排放量，并且规定了发酵木薯渣和啤酒渣的使用范围。
具体实施方式
下面结合实施例对本发明作进一步的描述。
实施例1
应用本发明配方于体外模拟水牛瘤胃消化代谢
体外模拟水牛瘤胃消化代谢应用瓶子系统，方法采用Mauricio等(1999)的压力读取式体外产气系统(Reading pressure system，RPT)进行体外瘤胃发酵培养，厌氧人工瘤胃缓冲液的配制按Menke和Steingass等(1988)方法配制。底物配方见下表1。
瘤胃液来源于选择三头体重约为400±5kg安装永久性瘤胃瘘管的水牛作为瘤胃液的供体动物。试验牛采用拴系式饲养，每日于8:00和17:00两次饲喂，自由饮水，常规光照、驱虫及管理。
在底物发酵6小时、12小时、24小时抽取10μl气体用手动式进样法用Agilent 7890A型气相色谱仪，色谱柱为HP-INNOWAX(19091N-133)毛细管柱，规格为30m×0.25mm×0.25um。测定气体中甲烷的含量。
