Along with the raising of China people income and food consumption level, China's milk industry is just presenting the trend of great development.To the end of the year 2003, the amount of livestock on hand of milk cow surpasses 6,000,000, and amount of livestock on hand is still increasing.Milk cow needs about 20 kilograms in ensilage every day, accounts for more than 40% of total food-intake.1 cow head year needed ensilage 5-7 ton, and the quality of ensilage and quantity delivered directly influence the output of milk and other production performance of milk cow.One of key factor of cattle farm success or not is the supply of quality silage, this has become raising dairy cattle person's a common recognition.
Ensiling is the effective means that green forage is stored.China belongs to monsoon climatic region, and just in time be rainy season the period of various places forage grass results processing, and modulation brings very big difficulty to hay, often causes the heavy losses of forage grass.Become hay to compare with the forage grass airing, the forage grass ensiling can be shortened the time of storing from gathering in to significantly, the forage grass loss of avoiding adverse weather to cause, and prolong storage period greatly, the nutritional labeling of green forage is preserved to greatest extent, and can significantly improve milk crop and quality.Ensiling of corn complete stool or corn straw silage are present modal ensilages, it accounts for more than 90% in ensilage, there is the problem of success rate in conventional corn silage, in ensilage, exist because of the lactic acid bacteria number quantity not sufficient, cause acidifying speed to cause the problem of nutritional labeling loss slowly, also have a series of problems such as secondary fermentation open behind the cellar for storing things, they all directly or indirectly influence the quality of ensiling.Improving corn silage all has important meaning to quality and the quantity delivered that improves the whole ensilage of China, and can bring huge economic benefit.Development has extremely important impetus to the milk industry.
Forage grass ensiling technology has 150 years of development history in countries such as America and Europes, and however, the ensiling technology of forage grass still obtains paying attention to, and new technology constantly obtains research and development.Especially in recent years, owing to taked new technology, the quality of ensilage obtains very big improvement, for very big contribution has been made in the dairy development of this country.On the ensiling material, pass through to adopt wilting, half-dried and additives for ensiling technology, on ensiling way, pass through measures such as more advanced machining and storage facilities, improved the ensiling technology, improved processing technology, thereby made the ensiling modulation really become the most effectual way that forage grass processing is stored.The Western European countries raise in the forage grass stock winter, and having more than 60% is that mode with ensiling is stored.High-quality forage grass ensiling relates to the integrated application of multi-subject knowledges such as agrostology, biochemistry, microbiology, materialogy, forage grass processing technology and machine-building.
Though forage grass ensiling technology has certain application in China, far lags behind developed country.Especially exploitation, research and the use at additives for ensiling seems very backward.The additives for ensiling product that Hansen Corp. of U.S. section is produced has carried out on a large scale entering China, and product price is up to 1800 yuan/kilogram, and begins to occupy market.Silage additive is the heat subject of countries in the world research, at present, the additives for ensiling of being researched and developed is also had nothing in common with each other, and such as organic additive, inorganic acid additive and Bacillus acidi lactici additive etc., wherein as the Study on Additive direction prospect is arranged with probio most.The research of China in this field is weak link, ought to accelerate to research and develop speed and strength, shortens the gap with foreign level.China's ensilage accounts for leading with corn silage, the additive that proposes to be used for corn silage helps improving the quality of corn silage, improves the production performance of animal.
