Optimum Conditions Screening Research On Natural Grass Boundles Silage

In this paper,China and The Inner Mongolia is rich in Natural grassland as background,However,recent year low supplies of Forage feed after crazing ban and indoor feeding,Modulation losses of hay,silage technology lags behind,the development rate of stock raising has been slow down recent years.The contradictions between grassland and livestock became more severe,income of farmers and herdsmen on stock raising reduced quickly.In order to solve the problem, studied on the key technical conditions of natural grass boundles silage and the quality of natural grass boundles silage in different storage periodand the Second fermente changes trend of natural grass boundles silage under water treatment after being opened"two years at Xilinguole.The research results showed that:①Ensilage the natural grass boundles when its moisture content was from 65%～70%,density was in the range of 350～400 kg/m~3,the silage grass not only has better sensory quality,better fermentation,higher silage success ratio and better stability,but also can preserve the nutritional ingredients effectively and make the silage grass has higher feeding value.②The additive can effectively improved the natural grass silage quality and stability.The digestible nutrient content was relatively high when the fungi amount was 0.50g/kg.③Cut the natural grass into pieces for silage,the grass sensory quality, fermentation quality,nutrition components and stability haven't change significantly. The best use of time for natural grass silage material was between 35-120 days after ensilaged.④It could effectively preserve the nutritional content,such as crude protein, crude fat and carotene by ensilaging natural grass.This mothod also decreased the fibers content,the digestive nutritional materials were also increased.
