Description
Technical field
The invention of a kind of ramie young stem and leaf coating ensilage and its processing method is related to plant-eating animal high-quality feed raw material
Technical field.
Background technique
Ramie (Boehmeria nivea L.) is the perennial root herbaceous plant of Urticaceae Section of Genus Boehmeria, is excellent
Bast fiber crop, young stem and leaf are good protein feed crops.The nutritive value of ramie young stem and leaf and " gold herbage "-
Clover is close, is good herbage raw material.It is very big that the biological characteristics of ramie have ramie as protein feed exploitation
Advantage.Ramie annidation is strong, and biological yield is big, can also grow well under the weather conditions of high temperature and humidity.At me
State south is not suitable for Planting Medicago sativa due to summer high temperature high humidity, but plantation ramie can obtain very high biological yield.Chinese agriculture
Ramie young stem and leaf hay varieties " Zhongsizhu No.1 " growth that crudefiber crop research institute, the industry academy of sciences selects is vigorous, sends out the root and stem of certain plants and Regenerated energy
Power is strong, and early growth is fast, is suitable for several times a year gathering in, year biological yield it is high.The kind blade is more, and stalk is thin, and leaf-stem ratio is big, makees
More reasonable for the yield component of feed, kind nutritive value is high." gold herbage " --- clover (is shown in Table 1) with northern
It compares, the tender plant siccative of " Zhongsizhu No.1 " children of plant height 65cm harvesting: in terms of nutritional quality, crude protein, crude fat, calcium contain
The indexs such as amount are higher, and coarse-fibred content is lower, and nutritive value is more excellent；In terms of yield, " Zhongsizhu No.1 " year dry
Matter yield is higher than 1.2 tons/mu, is significantly higher than clover；In terms of Production Zones Suitable, the characteristic of high temperature and humidity is not suitable with not with clover
Together, ramie happiness warms, is wet, and the damp and hot weather in south is very suitable to Ramie Growth.Therefore ramie feed is that south China is high-quality
The desirable feedstock of herbage and protein feed.
1 Zhongsizhu No.1 of table is compared with clover conventional ingredient
Ramie make feed feeding beef cattle and milk cow studies have shown that feeding siccative 3-4 kg/day, can substitute 50% a left side
Right fine fodder.In milk cow test, 50% or so fine fodder is substituted with ramie siccative, and does not have shadow to the output of milk and Milk quality
It rings.
The Livestocks such as beef cattle, milk cow, mutton sheep be Modern Animal Husbandry development emphasis, these animals based on grass, not with
People strives grain, is " grain-saving type " industry.And the herbage that south China is planted extensively is based on gramineous crop, good quality and high output adaptability
Strong herbage is seldom, is extremely lacked with high-quality protein herbage especially, is unfavorable for the high-speed and high-efficiency development of south " grain-saving type " animal husbandry.
" Zhongsizhu No.1 " compensates for the deficiency of south China scarcity high yield, high-quality protein herbage as southern characteristic forage crop.It pushes away
Extensive farming plants feeding ramie, is beneficial to south and develops " grain-saving type " animal husbandry, and livestock products yield and quality can be improved.
Ramie makees the maximum advantage of feed and is to reach cost-saving synergistic using its high protein, the characteristic of high yield, promote
The purpose of agricultural industry institutional adjustment.The ramie grass meal content of Hemp Inst., China Academy of Agricultural Sciences's research and development is up to 30% or more
Complete compound granular feed is applied in meat goose, beef cattle breeding respectively, and significantly reduces feed grain dosage, and thinks benefit
Making good use of ramie production Plant protein feed raw material is the basic of its industry development.
Forage crop is harvested, stored and fed in a manner of ensiling, is due to rain heat is with season weather in south
A kind of measure for generally extending herbage supply cycle, improving pasture utilization efficiency.Although ramie tender stem leaf feed protein content is high,
But since its crude fibre, crude ash content are high, energy is lower.Ramie tender stem leaf feed is identical as clover, due to its nutritional ingredient
High protein, high-moisture, low soluble-carbohydrate characteristic, high protein content improves its pH resiliency, in ensilage
Middle pH decrease speed is just slow, and it is relatively low to can lead to acidity, the fermentation of Yi Yinqi butyric acid.Soluble-carbohydrate (WSC) is too low, unfavorable
In sufficient lactic fermentation, pH value reduces theory calls.
Currently, ramie ensilage is modulated, mainly by passing through the by-product after ramie complete stool, cauline leaf or decorticating raw ramie
After sunning, and the higher crop material of other water-soluble carbohydrate contents, such as corn stalk, rice straw, according to a certain percentage
Mixing, is attached to the lactobacillus-fermented on plant residue using nature and is made.Due in ramie raw materials in ramie ensilage
The effect of plant rennet and microbial protease makes it not so that a large amount of true albumen in ramie are broken down into nonprotein nitrogen
Only it is not easy ensiling and energy is lower, and nonprotein nitrogen acts on final synthesis urinary nitrogen through rumen-undegradable and body is discharged
Outside, the serious waste of nitrogen is caused.
In addition, ramie is after sunning, chlorophyll, vitamin, chlorogenic acid, Flavonoid substances etc. are in strong light, high temperature
It is seriously destroyed under effect, the due effect for further increasing animal immunizing power and animal product quality is also by serious
It influences.Therefore, the fresh strain of ramie how is efficiently used, its silage effect is improved, significantly reducing albumen nitrogen loss is to improve ramie blueness
Store the important measures of food utilization efficiency.But have not yet to see relevant report.
