Description

A kind ofly be used for the feedstuff matched of early weaning piglet

Technical field

The present invention relates to a kind of the feedstuff matched of early weaning piglet that be used for, belong to field of feed.

Background technology

In China, compare with traditional weaned piglet age in days, generally claim the wean of 21～35 ages in days to be early weaning, and claim the wean in the past of 21 ages in days to be ultra-early weaning.At present China's large-scale pig farm is generally carried out the wean of 23～28 ages in days, and 21 ages in days wean more rare, and the wean of external 14～21 ages in days is many implemented wean during general 2 ages in week, and the age in days of average wean has the difference in 1～2 week both at home and abroad.

The biggest obstacle of early weaning, especially ultra-early weaning is that the digestive function of piglet is unsound, and is high especially to the requirement of feed.Under the super segregated early weaning condition, the use of the research of piglet nutritional requirements and suitable special feedstuff and daily ration preparation, feed processing etc. provide direct theoretical foundation for effective enforcement of isolating ultra-early weaning, and the application of supporting breeding technology then is the key of isolating the early weaning success.

So the preparation of early-weaned piglets material and application are directly connected to weanling pig growth and the performance of production performance from now on.

Summary of the invention

The purpose of this invention is to provide a kind of 14～21 ages in days wean of realizing, nutrient concentration height, good palatability, easily digest and assimilate be used for the feedstuff matched of early weaning piglet.

A kind of feedstuff matched preparation method who is used for early weaning piglet, its step is as follows:

The first step. the raw material impurity elimination

Various raw materials packed or in bulk through being discharged into discharging pit after the metering, behind drag conveyor, bucket elevator, enter the cylinder receiving sieve respectively, and after dedusting was done odds and ends, it was assorted except that de-iron to enter pipe magnetic separator;

Second step. raw material pulverizing

Various raw materials enter large and small pulverizer respectively and pulverize;

The 3rd step. take by weighing each raw material for standby by weight percentage;

The 4th step. raw material mixes

Each raw material is directly added the horizontal-type biaxial paddle type mixer mix, incorporation time 30～60s, the mixture homogeneity coefficient of variation reaches below 7%;

The 5th step. granulate

Adopt the pellet of 2.5-2.7mm aperture ring die pelleter extrusion to rely on gravity flow to enter in the upright radiator raw material that mixed and cool off the modified time of granulation: 3 minutes, refining temperature: 60-65 ℃, steam pressure: 4Kg, particle diameter length: 3-6mm;

The 6th step. finished product packing

The particle that makes by automatic packing machine finish weigh, pack, package.

The factor of restriction early-weaned piglets post-weaning growth performance has: digestive ferment contains that quantity not sufficient, absorbability reduces, the sour ability of secretion weakens, obtains benefit materials are cut off from breast milk, the antigenicity of feed feed intake deficiency, feedstuff etc.When designing feed formula, must consider these factors, and try every possible means to overcome them for early-weaned piglets.

1. digestive ferment hyposecretion

Newborn piglet innately has digestion breast milk ability, and wherein lactase, lipase and protease level are higher, but the activity of other various enzymes when 3 ages in week no more than 50% of the pig that grows up.Early weaning has a strong impact on the activity of piglet digestive ferment, various pancreatin are active in 1 week of wean significantly reduces, other enzymes 2 weeks after wean the time return to the wean level except that pancreatic lipase, and intestinal enzymes (lactase, invertase, maltose etc.) activity also significantly reduces simultaneously.And therefore the digesting and assimilating the participation that all needs corresponding enzyme and just can carry out of all nutriments in the piglet body must consider in daily ration that interpolation contains the complex enzyme formulation of endogenous enzyme, as protease, lipase, amylase etc., with the deficiency of additional endogenous enzyme.

2. absorbability descends

In lactation, the newborn piglet intestinal villus physically well develops, and can give full play to digestion and absorption function.Wean has brought small intestine form and histology to change, and intestinal villus length is shortened and crypts deepens, and the wean age in days is littler, and the cytothesis rate is low more, and villus length is short more during wean.When preparation early-weaned piglets daily ration, should select the raw material that is easy to digest and assimilate for use, as SDPP, intestine membrane protein, white fish meal, whey powder, lactose, fermented soybean albumen etc.

3. gastric acid secretion deficiency

The gastric acid secretion deficiency is another defective of early-weaned piglets.Hydrochloric acid in gastric juice participates in the activation of propepsin.The optimal pH of performance pepsin activity is respectively 2.0 and 3.5.The gastric acid secretion deficiency will directly cause stomach inner pH value to raise, and causes pepsin activity to descend, and protein digestibility reduces.On the other hand, hydrochloric acid in gastric juice can also suppress to enter GI bacterium from the upper end alimentary canal, and the gastric acid secretion deficiency will cause the variation of enteric microorganism flora, cause the disorders of digestion, and piglet easily has loose bowels.Should additionally replenish acidulant in the weanling pig daily ration in early days, or add some special raw materials such as whey powder or lactose, these raw materials produce Bacillus acidi lactici by the fermentation of internal microorganism, thereby reduce the pH value in the body.

4. immunity degradation

Breast milk, particularly colostrum are the primary sources of preceding required immunocyte of specific immunity of weaned piglet and immunoglobulin (Ig), and newborn piglet does not have immunocompetence, and be main by absorbing immunoglobulin (Ig) from first Ruzhong.Along with the passing of time lactation, immunoglobulin content sharply descends in the breast milk, and the immunocompetence of piglet self could slowly be grown when 3 ages in week.The piglet of 10～18 ages in days wean is in its floor level of immunity in life just, and piglet is to the resistance extreme difference of cause of disease at this moment.Therefore, the early-weaned piglets material should be able to improve the immune level of piglet.And contain 15～20% immunoglobulin (Ig) in the SDPP, and can intactly absorb a part wherein after piglet searches for food, thereby improve resistance disease, particularly this effect is particularly outstanding in poor environment.The extra immunoglobulin class material that replenishes also can strengthen little pig immunity, strengthens premunition and reduce affect.This is for improving piglet survival ratio and improving piglet health status, and meaning is very great.

5. the breast milk physiological activator disappears.Studies show that recently the most direct influence of weanling pig immunity function is exactly that the immunologic active material disappearance of newborn source has promptly lost passive immunity; On the other hand, contain some in the breast milk and promote intestine of young pigs to grow and influence active material such as EGF, insulin and insulin-like growth factor, polyamines and the glutamine etc. of nutrient digestion and absorption, these active materials disappear will directly influence the growth performance of weanling pig.Therefore, in the daily ration of weanling pig, replenish the villus length that paddy ammonia phenol amine can increase weanling pig, reduce the crypts degree of depth, thus slow down early weaning stress influence.

6. the intestines and stomach fungus strain changes

The newborn piglet enteric microorganism is mainly from the microorganism in sow vagina, ight soil and the environment.Suckling pig is a dominant microflora with the Bacillus acidi lactici, and pH keeps reduced levels.Therefore seldom find enterotoxigenic escherichia coli in the piglet ight soil before the wean, and enterotoxigenic escherichia coli and non-enterotoxigenic escherichia coli exist in a large number in the ight soil of wean back, even become dominant bacteria, thereby cause diarrhea of weaned piglets.Replenish some probiotics in early days in the weanling pig daily ration, purpose is to form good microbiota in alimentary canal, makes animal in shape.The mechanism of action of probiotic is the growth and breeding that promotes beneficial bacterium, reaches the purpose that suppresses harmful bacterium by the growth and breeding that promotes beneficial bacterium simultaneously.

7. feed intake deficiency

Feed intake plays a significant role on piglet growth performance.The feed intake deficiency is the principal element of restriction piglet growth performance performance.Enough feed intakes can reduce the infringement of enteron aisle morphosis and immunity function inhibition.So the preparation of early-weaned piglets daily ration has quite high requirement to palatability.And add flavouring agent, sweetener can effectively improve the feed intake of piglet.The composition that early-weaned piglets is had a liking for most is a sucrose, adds sucrose in early days in the weanling pig daily ration and can satisfy simple carbohydrate needs, can improve the feed intake of early-weaned piglets as sweetener again.

Advantage of the present invention is:

1. the aromatic uniqueness of taste induces piglet to open food ahead of time, promotes stomach and intestine physiogeny;

2. good palatability, feed intake is big, at utmost slows down ablactation stress, and is not weightless after the wean, keeps efficiently growth;

3.14 the wean of～21 ages in days prevents that effectively piglet from catching, and improves a pig general level of the health;

4. the average daily gain of weaning back ten days obviously is better than like product, and the back ten days average daily gains that wean are in 280-350 gram/sky, and product of the same type is in 220-250 gram/sky on the market.
