摘要
应用体外产气法测定阴离子盐对人工瘤胃体外发酵产气量、pH值、干物质消失率及NH3-N浓度的影响。试验分为3个组,对照组和2个试验组饲粮干物质中自制阴离子盐分别占0%、1.87%、3%。结果显示,阴离子盐对人工瘤胃的最大产气量没有影响,但显著降低了产气速率(P<0.05);与对照组相比,2个试验组干物质消失率有所降低,但差异不显著(P>0.05)。发酵24h后,试验组pH值比对照组有所提高,但差异不显著(P>0.05);试验1组NH3-N浓度显著高于试验2组(P<0.05),但对照组和试验组间差异不显著(P>0.05)。
The objective of this study was to investigate the effect of anionic salts on rumen fermentation in vitro.Diets were assigned three groups(control,0% anionic salts;treatment 1,1.87% anionic salts;treatment 2,3% anionic salts contained in dietary DM).After gas production(GP) was recorded,the content was determined for the pH value,the degradability of DM and concentration of N-NH3.Results of this study showed that GP was not affected by the anionic salts.Rate of GP decreased significantly for the two treatme...
