摘要
试验旨在研究不同植物对体外瘤胃总产气量(GP)和甲烷(CH4)产量的影响.试验以11种植物的枝叶为材料,进行体外发酵培养,测定体外发酵24h后的GP和CH4产量.结果表明:在4种灌木、半灌木牧草中,紫丁香的GP最高;在多年生牧草中,紫花苜蓿、黄花苜蓿、百脉根、野大豆GP显著高于野豌豆、沙打旺和野艾蒿(P＜0.05);紫丁香和冷蒿的CH4产量低于达乌里胡枝子和百里香.紫丁香和野豌豆能够减少CH4产量,提高微生物蛋白(MCP)含量.紫丁香、黄花苜蓿和野豌豆的总皂苷、生物碱含量与GP呈正相关,与CH4呈负相关.研究表明,紫丁香、野豌豆和黄花苜蓿可以作为优质的饲料添加剂,调控反刍家畜瘤胃产气特征.
Abstract
The purpose of the experiment was to study the effects of different plants on rumen total gas production(GP)and methane(CH4)production in vitro.In this experiment,the branches and leaves of 11 plants were used as materials for in vitro fermentation,and the yields of GP and CH4 were measured after 24 hours of fermentation in vitro.The results showed that the GP of Syringa oblata was the highest among the four shrubs and subshrubs.Among the perennial forages,the GP of Medicago sativa,Mcdicago falcata,Lotus corniculatus,and Glycine soja was significantly higher than that of Vicia sepium,Astragalus adsurgens,and Artemisia lavandulaefolia(P＜0.05).The CH4 yield of Syringa oblata and Artemisia frigida was lower than that of Lespedeza davurica and Thymus mongolicus.Syringa oblata and Vicia sepium could reduce CH4 yield and increase microbial protein(MCP)content.The contents of total saponins and alkaloids in Syringa oblata,Mcdicago falcata,and Vicia sepium were positively correlated with GP and negatively correlated with CH4.The study indicates that Syringa oblata,Vicia sepium and Mcdicago falcata can be used as high-quality feed additives to regulate rumen gas production characteristics of ruminants.
