Description
Technical field
The present invention relates to a kind of fermentation material, more particularly to a kind of sweet tea napier grass fermentation material for improving farrowing sow production performance
And preparation method and application.
Background technology
Sow production performance is always one of bottleneck for restricting the fast development of China's pig breeding industry, and height directly affects me
The production efficiency and economic value of state's pig breeding industry.China is pork consumption big country, and data shows that China's pork consumption in 2017 is total
54,870,000 tons are measured, the live pig amount of delivering for sale 688,610,000, sow breeding stock 36,120,000, sow annual offer piglet number is 19.0
Head or so.Domestic and international sow production performance has very big difference, is shown according to related data in 2017, America and Europe, Denmark etc.
The sow annual of developed country provides piglet number and has reached 30 or so, and domestic and international sow annual provides the gap of piglet number
It is 10.0 or so.
So it is the key that shorten domestic and international technical merit to improve sow production performance, and influence sow production performance
Factor is more, such as the selection of management level, germline, daily ration level, health degree, and wherein daily ration level is most important factor
One of, and farrowing sow takes limit to raise mostly, therefore in limited feed intake how by the improvement of daily ration level with accurately grind
Hair is of great significance to improving sow production performance.Fiber is important component in sow diets, is mainly used in conventional feed
Wheat bran, apple pomace, Alfalfa, napier grass etc. improve the quality of fibre fractionation, but actual effect is also undesirable.
Wheat bran is wheat processing byproduct, is the conventional fibre component that usage amount is 18%-25% in China's sow material, because of valency
Lattice are cheap, yield is high, fiber content is high, can increase complete diet pellet volume, increase sow, and reasons such as rich sense of satisfying are widely used, but
It easily grows microorganism, causes mycotoxin largely exceeded, sow feeding is containing a large amount of because free moisture content is high, freshness is low
After the wheat bran feed of mycotoxin, intoxicating phenomenon is generated, it is long, dead such as constipation, litter size decline, false heat, stages of labor occur
Phenomena such as tire increases seriously affects sow production performance.
Apple pomace is residue of the apple after crushing squeeze juice extracting, rich in soluble sugar, vitamin, minerals and fiber
Etc. abundant nutritions substance, but apple pomace is limited by price factor used in livestock, and mostly putrid and deteriorated apple is squeezed
It forms, yield and purchasing channel are also unstable, therefore inconvenient stablize uses in pannage.
Alfalfa is one of longest high quality forage of world's cultivation history, rich in battalion such as albumen, fiber and trace elements
It forms point, but clover grass product is seriously insufficient at present, the annual total demand in China is at 30,000,000 tons or more, but yield only has
It 4000000 tons or so, is only capable of meeting larger and higher intensive degree cattle farm demand, other use demands can not obtain
Meet, cause the Alfalfa product cost used in sow feed higher, and rise year by year, directly affect pig breeding industry to lucerne
The demand of Mu grass, so can not largely be used in farrowing sow feed.
Napier grass is originated in from Africa, is one of perennial high yield and high quality herbage cultivated extensively, because its is adaptable, yield
It is high, be not likely to produce the reasons such as mycotoxin, insect pest ability be strong and start to be widely used, but it mainly feeds mode by fresh,
Need frequently to harvest, and due on blade flagellum it is more, when harvesting, easily cuts hand, can lead to whole body itch, and there is addition
The problems such as higher, feeding effect is general is measured, so not received generally by market also.
Chinese patent application No. is 201710939290. X discloses " a kind of processing method of ensilage ", passes through
The ensiling raw material that the rosette state of witloof to bolting initial stage and the jointing stage of hybridization napier grass are formed, is dehydrated after cutting segment
