Abstract
The invention discloses a feed additive for improving intestinal functions of piglets and an application of the feed additive. The feed additive is formed by combining and processing two or more of copper chitosan, zinc chitosan, ferrous chitosan and selenium chitosan according to a certain proportion; two or more inorganic microelements in the four combined substances do not need to be added into feed for the piglets; and 0.05%-2% of the feed additive provided by the invention is added to the piglet feed, so that the diarrhea rate of the piglets is remarkably reduced, the daily gain of the piglets is improved, the feed to gain ratio is reduced, and the disease resistance of the piglets is enhanced. The feed additive provided by the invention can be used for directly replacing common inorganic microelement additives, so that the problem of environment pollution caused by application of high copper and high zinc is avoided. Through a plurality of feeding experiments and laboratory detection, the feed additive has a remarkable effect, and is safe and non-toxic; and moreover, feeding animal products meet the requirements on national food sanitation.
Description
Technical field
The present invention relates to a kind of feed addictive and application thereof that improves intestines function of piglings.
Background technology
It is the key link of Swine Production that weanling pig produces.Since when wean be subjected to psychology, environment and nutrition stress impact, piglet usually shows that appetite is poor, the disorders of digestion, diarrhoea, growthing lag and efficiency of feed utilization are low etc. so-called " weaning syndrome of piglets ".Wean is easily destroyed the intestinal villi of piglet by bacterium and diet, thereby impact is to the abilities of digestive and absorption of nutriment.Behind the weaned piglet, change suddenly the picked-up solid feed into by picked-up liquid milk.When daily ration contained a large amount of grass family cereal, under the abrasive action of plant dry matter, intestinal villus very quick-wearing shortened, and fuzzy surface becomes flat ligule by high density finger-like, and crypts is deepened.This variation will continue 7 ~ 14 d, thereby reduce the absorption area of small intestine to nutrient, have a strong impact on secretion and the absorbability of its digestion process.Weanling pig is because gastrointestinal development is incomplete, and the digestive ferment hyposecretion adds the reasons such as immune system imperfection, premunition be poor, indigestion easily occurs and feed is produced irritated phenomenon, thereby cause diarrhoea, has a strong impact on the growth of piglet.
The correlative study of alleviating ablactation stress, raising intestines function of piglings is one of study hotspot of the worker that raises pigs at present.For example, in the weanling pig feed often with zinc oxide, copper sulphate form add high dose zinc (2000～2500mg/kg), copper (200～250mg/kg), have the effects such as the piglet of raising daily gain, feed intake, reduction diarrhea rate.But the use of high doses of copper zinc has brought many problems, as causes the wasting of resources, environmental pollution, copper poisoning, the absorption of disturbing other mineral elements, pig staple length skin dark etc.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this invention is to provide a kind of feed addictive that improves intestines function of piglings.
It comprises in chitosan copper, chitosan-zn, chitosan ferrous, the chitosan selenium two or more, and compatibility processes in proportion.
Each material proportioning can be following a kind of technical scheme in the feed addictive of raising intestines function of piglings:
(1) chitosan copper: the chitosan-zn ratio is 1: 0.5～1 (respectively in copper, zinc);
(2) chitosan copper: chitosan ferrous ratio is 1: 0.5～1 (respectively in copper, iron);
(3) chitosan selenium: the chitosan copper ratio is 1: 1000～1500 (respectively in selenium, copper);
(4) chitosan-zn: chitosan ferrous ratio is 1: 0.5～1 (respectively in zinc, iron);
(5) chitosan selenium: the chitosan-zn ratio is 1: 1000～1500 (respectively in selenium, zinc);
(6) chitosan selenium: chitosan ferrous ratio is 1: 1000～1500 (respectively in selenium, iron);
(7) chitosan copper: chitosan-zn: chitosan ferrous ratio is 1: 0.5～1: 0.5～1 (respectively in copper, zinc, iron);
(8) chitosan selenium: chitosan copper: the chitosan-zn ratio is 1: 1000～1500: 1000～1500 (respectively in selenium, copper, zinc);
(9) chitosan selenium: chitosan copper: chitosan ferrous ratio is 1: 1000～1500: 1000～1500 (respectively in selenium, copper, iron);
(10) chitosan selenium: chitosan copper: chitosan-zn: chitosan ferrous ratio is 1: 1000～1500: 1000～1500: 1000～1500 (respectively in selenium, copper, zinc, iron).
A kind of application of feed addictive of described raising intestines function of piglings, described feed addictive is made dry powder-shaped, add in mixed feed, concentrate feed, the premix, mix, the mass percentage content that described feed addictive addition accounts for mixed feed is 0.05%～2%.
Beneficial effect of the present invention:
Set about from the alimentary canal physilogical characteristics of piglet, utilize the physicochemical property of shitosan, multiple material with raising function of intestinal canal and body's immunity is carried out reasonable compatibility, thereby successfully developed a kind of feed addictive that improves intestines function of piglings.Use the feed addictive of raising intestines function of piglings of the present invention, can significantly improve the average daily gain of weanling pig, reduce the material anharmonic ratio, significantly reduce diarrhea of weaned piglets.Can significantly improve rear 14 days duodenum contents of wean, the total protease of pancreas, amylase, tryptic activity, significantly improve two all intestinal villus height after the wean, reduce the crypts degree of depth.Can obviously improve the secretion of casing slime sIgA, reduce the apoptosis of small intestine cells, thereby improve function of intestinal canal, improve it to the absorption of nutriment, promote growth, have significant economic benefit and ecological benefits, have a extensive future.
In pig starter feed, add the feed addictive of 0.05%～2% raising intestines function of piglings of the present invention, can significantly reduce the diarrhea rate of piglet, improve daily gain, reduce the material anharmonic ratio, strengthen piglet disease-resistant power.The feed addictive of raising intestines function of piglings of the present invention can directly substitute inorganic microelement additive commonly used, avoids the problem of environmental pollution that brings in response to high-copper, Gao Xin etc.Through repeatedly feeding experiment and laboratory detection, this additive effect is remarkable, safety non-toxic, and the animal product of feeding meets the state food hygienic requirements.
