Description
Technical field
The present invention relates to a kind of piglet premixed feed improved technologies, belong to IPC classification A23K and are specially adapted for animal
Feed for nursing and its production method technical field, especially son~composite premixed feed for pig and preparation method thereof.
Background technique
Piglet is the stage more fragile in pig growth course, therefore the key that their raising is just raised at pig full period
Link.Piglet digestive system not yet reaches maturity, digestive ferment and gastric acid hyposecretion, immunity are low and stress be big, at this time young
Pig feed formula is just particularly important.It can be divided in the raising to early-weaned piglets are as follows: Initial Stage of Weaning and 5~25kg stage
(or being further divided into 5~10kg, 10~25kg) segmentation raising, the producer should respectively raise the physiology in stage and nutrition for piglet and need
Feature is asked to provide the feed different with reasonable preparation.With the development of pig breeding industry, the Weaning Age of piglet constantly shifts to an earlier date, and often can
The generation for leading to piglet " early weaning syndrome " shows as the situations such as diarrhea, efficiency of feed utilization reduction, the disorders of digestion.
Some research thinks that the main mechanism of diarrhea is that permeability increases, excessive secretion and permeability increase, stomach and intestine function
Disorder is often peripheral issue.Under any circumstance, diarrhea can all develop into nutrient malabsorption or indigestion.It reduces
The incidence of grice diarrhoea first has to physilogical characteristics and growth rhythm in conjunction with piglet, scientific matching.
The main reason for some research is thought, " early weaning syndrome " occurs is: mucous membrane of small intestine is as digestion and absorption
The main place of nutriment, under the great variety that weaning stress period occurs in form, structure and function, villi height
Drop, Crypt depth increase, and duodinum digestive enzyme activity is insufficient, the inferior problems of pigling immunity.
There are also researchs to think, after weaned piglet, becomes the biggish solid feed of particle from breast milk.Main component is jade
The vegetable raw materials such as rice, dregs of beans, to digest the lactase of breast milk lactose gradually to digestible starch in enteron aisle before and after weaned piglet
Based on maltose and sucrose enzymic transformation.The anti-nutritional factors of protein especially β-companion's globulin in dregs of beans etc., is not easy
It is absorbed, easily causes the trophism diarrhea of piglet.

Rush down (Poulsen, 1995；Cromwell, 2002；Xu etc., 2011；Heo etc., 2013).
In order to solve early weaning syndrome, animal producer can largely add antibiotic in the feed for piglet, to mention
The disease resistance of high suckling piglet reduces harmful microorganism growth, but the main reason for cause early weaning piglet syndrome in fact
Not in harmful microorganism, digestion and absorption function is affected, the presence of anti-nutritional factors and immunity degradation are main causes,
In feed on the one hand long-term use antibiotic can not inhibit trophism diarrhea, and antibiotic can destroy alimentary canal microenvironment
Balance is easy to cause autogenous infection.Drug resistance brought by the abuse of another aspect antibiotic, to human health and environment band
Carry out adverse effect.The high-energy feeding generallyd use to improve piglet speed of growth, also brings such as indigestion, generation
The problems such as thanking dysfunction, trophism diarrhea.Antibiotic and pharmacology heavy metal although preferable clinical effectiveness, but cub is easily
To drug generate rely on and drug resistance, if in addition such drug long-time service can generate toxicity, side effect accumulation, cause heavy metal
Pollution, seriously affects the normal development of young age piglet.
Improved technology is more, for example, to make weanling pig adapt to feeding feed as early as possible, what reduction was generated by wean is answered
Swash, usually 7~10d starts supplementary feeding creep feed after piglet birth.The quality of creep feed should be close with breast milk, raw material with dairy products or
Based on milk replacer, since palatability is good, easy to digest, piglet feed intake can be increased, improve weanling weight.
Piglet breeding feed in the prior art is popular breeding feed, and prescription is fairly simple, cultivates specific aim
It is not strong, it cannot be according to effectively being selected during cultivation, the trophism of breeding feed is not comprehensive enough rationally.Early-weaned piglets

It is reported in weaning pigs for the first time from Danish scientist Poulsen 1989 and adds 3000mg/kg zinc oxide drop
Grice diarrhoea rate after low wean, pig breeding industry begins to prevent and treat diarrhea of weaned piglets using high zinc dietary, and achieves certain effect
Fruit, however high zinc dietary influences the absorption of other microelements, easily there is the pale colour of skin, staple length, poor in piglet after continuous use 2 weeks
It is phenomena such as blood, most of to be excreted with excrement and pollute environment since the bioavailability of zinc oxide is lower.It is reported that feeding
After Pharmacological Level of Zinc (3000mg/kg) by digesting and assimilating in vivo, zinc is up to 16832.26mg/kg, high dose in the excrement of excretion
Zinc can contaminated soil and underground water, influence human lives, health, safety, interfere the sustainable development of animal husbandry.
The preparation of pig starter feed notes also:
1. low-protein diet can reduce the generation of grice diarrhoea.
2. high-energy ration can be prepared by the fat (vegetative grease) of addition 3%~5%.To improve daily ration palatability,
Improving piglet weight gain and efficiency of feed utilization etc. has better effects.
There is reinforcing to make the pepsin of 2 weeks piglets after wean 3. adding organic acid and calcium formate etc acid supplement in daily ration
With.Additive amount of the acid supplement in daily ration is generally within 0.3%~0.5%.
4. the complex enzyme formulation containing protease, amylase, pectase, cellulase can strengthen piglet for piglet diet
The activity of stomach and intestine enzyme facilitates digestion complicated protein and carbohydrate.It additionally needs to supplement suitable iron, zinc, copper etc.
Minerals and crude fibre.
In conclusion present invention research is thought, no matter grice diarrhoea caused by which kind of factor, be because of this kind or a variety of
Factor causes intestine of young pigs to damage through a variety of ways, including increases intestine of young pigs permeability and permeability, so that piglet intestines
Road excessive secretion, nutrition digestion function reduction, immunity reduce, and eventually lead to diarrhea.Therefore, no matter with which kind of means, which kind of
