The effect on long-chain fatty acids in lucerne silage with jujube powder and Lactobacillus plantarum

摘要

The major nutrients of lucerne silage arc well documented. However; forages are also an important dietary source of a-linolenic acid (C18:3n-3) and linolcicacid (C18:2n-6) that are biohydrogenated in the rumen, originating a complex pattern of C18 fatty acids (Jenkins et al. 2008). Studies have reported slight effects on the fatty acid (FA) composition of grass silages by the use of additives like formalin, formic acid, or enzymes (Alves et al. 2011) However, there are no studies on the addition of jujube powder in lucerne silage, which has a high sugar content. The effect of Lactobacillus plantarum (LA) on the silage fermentation quality has been frequently observed. Few studies have focussed on long-chain fatty acids in lucerne silage with jujubepowder and Lactobacillus plantarum.The objective of this study was to evaluate the effect of the addition of jujube powder and the Lactobacillus plantarum on the long-chain fatty acids (mainly C16-C18) in lucerne silage.
