The silage making and nutritive variation of Trifolium ambiguum

WEI Chun-qiu,WANG Ming-jiu(Ecology and Environmental Science College,Inner Mongolia Agricultural University,Inner Mongolia Huhhot 010019,China)  
Trifolium ambiguum was used as raw material at nutrition period after maturity.Six treatments were composed of 2 cm,5 cm cutting,whole plant,with and without microorganism starter,with three replicates.These silage materials were bagged,crammed,sealed and ensilaged.The sensory evaluation and determination of nutritional components were carried out after 45 days.The treatment with 2 cm cutting and microorganism starter was better by sensory evaluation,at this time the alcohol flavor was strong,the color was yellow green,the leaves structure was good and the level of rotten was low.Based on nutritional components determination of T.ambiguum,crude protein content of the treatment with 2 cm cutting and microorganism starter was 20.25%,NDF and ADF were lower than the treatment of 2 cm cutting without microorganism starter.In a word,high moisture T.ambiguum silage had excellent effect,and silage quality of adding microorganism starter was better than direct silage.The objective of this study was to discuss the effects of silage methods on silage quality of T.ambiguum and to provide theoretical basis for efficient utilization of the grass.
