The application of microstorage technique in the Shigatse region,Tibet

The experiment was carried out to investigate the effect of microbial silage bacterium on the nutritional components of three materials, including oat（Avena sativa）, barley straw（Hordeum vulgare var.nudum） and mixture of oat and alfalfa （Medicago sativa）in the Shigatse experiment station. The results of this study showed that the three materials could produce high quality silage, and the microbial silage of the mixture of oat and alfalfa was better than that of oat. The crude protein of barley straw and mixture of oat and alfalfa increased by 41.74% and 39.73% and was 5.12% and 10.68%, respectively. The general energy (GE) and nitrogenfree extract (NFE) of three materials declined due to microbial silage bacterium treatment, in which GE and NFE of barley straw were the lowest and were 2.46% and 15.76%, respectively. This study suggested that the microbial technology solved the problem of forage lacking in spring and winter to improve animal production in the Shigatse regions as a useful scientific and technological.
