Abstract
The present invention relates to a kind of pregnant sow anti-heat stress feed additive, it is made of Chinese herb feed additive, sodium acid carbonate, citric acid, lysine, aminobutyric acid, fructooligosaccharide and wheat bran.The feed addictive of the present invention effectively alleviates the constipation problem of pregnant sow heat stress and pregnant sow, it is possible to increase the feed intake of sow, prevents heat stress from causing embryonic death, improves litter size.
Description
Technical field
The present invention relates to animal feed additive field, and in particular to a kind of pregnant sow is added with anti-heat stress feed
Agent.
Background technology
The sow gestation phase terminates since ovum fertilization to childbirth, 114 days average（111-117 days）.The growth hair of fetus
Educate and fully rely on parent, the feeding management of pregnant sow is directly related to the growth and development of embryo, litter size, birth weight, piglet
Survival rate, daily gain, milking capacity and the rutting in next cycle.Good feeding management is carried out to gestational period sow, can
Make sow in gestation weight gain, ensure that embryo growth and development is good, reduce the death of embryo to greatest extent, produce
The piglet that head number is more, birth weight is big, vitality is strong, the body condition of sow postpartum unsoundness and good milk performance, so as to carry
High pig production is horizontal.Pig belongs to homeothermal animal, and sweat gland is undeveloped, and internal thermal energy distributes relatively slowly, radiates when the heat production of pig is more than,
Body temperature raises, and physiological responses to heat stress easily occurs.Research shows, before and after insemination of sows 1-3 weeks it is especially sensitive to high temperature, before and after breeding
With 1-3 weeks after the breeding interior sow by heat stress, its conception rate substantially reduced, and the absorption of embryo's early stage and death occurred, because
And litter size substantially reduces, latter half of gestation is the fetal weight increased critical period, and high temperature can influence the normal development of fetus, pregnant
Sow later stage of being pregnent is subjected to heat stress, has certain influence to the passive immunity of fetus to sow.In addition, summer high temperature causes sow hot
Stress while also result in sow water and salt metabolic disturbance, gastrointestinal peristalsis slows down, so as to cause prevention of sow constipation, sow band is given in constipation
The harm come is mainly manifested in：Farrowing increased periods are even had difficult labour, and sow is influenced by heat stress, internal hypersecretion
Adrenaline, causes uterine vascular to shrink, so that the oxytocins for reaching uterine smooth muscle is reduced, what uterus muscle cannot be enough
Oxygen, causes uterotonic frequency and intensity to reduce, causes delivery time to extend.Produce weak stillborn foetus number increase, the strong son of sow production
Number declines, and son's rate living reduces；Postpartum appetite reduces, dysgalactia, and milk production is reduced etc..
At present the control measure of pregnant sow heat stress is included taking measures of heat control, nice and cool ring is provided to sow
Border, increases the fat content in feed, vitamin C, vitamin E, sodium bicarbonate, trace element chromium and electrolyte is added in feed
Deng however, existing measure is all part and alleviates, without relatively good effect.There is an urgent need to develop a kind of pregnant sow
Anti-heat stress feed additive, technical support is provided to alleviate pregnant sow heat stress, makes the production level on pig farm in sweltering heat
It is not subject to serious influence under environment, obtains maximum value.
The content of the invention
The problems such as heat stress present in the cultivation of existing pregnant sow and constipation, the present invention is intended to provide a kind of gestation
Female anti heat stress fodder additive for pig.
To solve above technical problem, the present invention uses following technological means：
A kind of pregnant sow anti-heat stress feed additive, is made of the raw material of following parts by weight：Chinese herb feed additive
45-55 parts, 2-9 parts of sodium acid carbonate, 3-6 parts of citric acid, 3-5 parts of lysine, 4-8 parts of g- aminobutyric acids, 7-11 parts of fructooligosaccharide and
20-25 parts of wheat bran is made；
The raw material proportioning of the Chinese herb feed additive is as follows：6-10 parts of wrinkled giant hyssop, 3-6 parts of Poria cocos, ophiopogon 3-6 part, hawthorn 5-9
Part, 3-6 parts of cassia seed, 2-5 parts of reed root, 3-7 parts of dried peppermint leaf, 4-6 parts of felwort, 4-7 parts of luffa pericarp, 2-4 parts of wilsonii, Lonicera and Forsythia
4-8 parts, 3-5 parts of radix glycyrrhizae.
Preferably, the feed addictive is made of the raw material of following parts by weight：50 parts of Chinese herb feed additive, sodium acid carbonate
22 parts of 5 parts, 4 parts of citric acid, 4 parts of lysine, 6 parts of g- aminobutyric acids, 9 parts of fructooligosaccharide and wheat bran are made；
The raw material proportioning of the Chinese herb feed additive is as follows：8 parts of wrinkled giant hyssop, 5 parts of Poria cocos, 4 parts of ophiopogon, 6 parts of hawthorn, cassia seed
4 parts, 3 parts of reed root, 5 parts of dried peppermint leaf, 5 parts of felwort, 6 parts of luffa pericarp, 3 parts of wilsonii, 4 parts of Lonicera and Forsythia, 3 parts of radix glycyrrhizae.
The preparation method of heretofore described pregnant sow anti-heat stress feed additive includes the following steps：
（1）Chinese medicine material is weighed, is mixed, heats and carries after the water immersion half an hour for adding 4-10 times of Chinese medicine material gross weight
Take, extraction time for 2-4 it is small when, filtering adds the water heating extracting of 4-10 times of Chinese medicine material gross weight in filter residue, during extraction
Between for 2-4 it is small when, filtering, merges filtrate twice；
（2）Gained filtrate obtains Chinese herb feed additive pulvis through being concentrated under reduced pressure, drying, crushing；
（3）By proportioning by step（2）Obtained pulvis and sodium acid carbonate, citric acid, lysine, g- aminobutyric acids, Portugal
Grape sugar and wheat bran mixing, stir evenly, 40 mesh sieves are crossed after crushing, obtain the pregnant sow and are added with anti-heat stress feed
Agent.
Pregnant sow of the present invention by the use of anti-heat stress feed additive can as pregnant sow premix into
/ mono-, it can also be directly appended in pregnant sow mixed feed, the pregnant sow is with anti-heat stress feed additive pregnant
The additive amount being pregnent in sow mixed feed is 0.1-0.3% by weight percentage（Mass percentage）.
Advantages of the present invention：
1. coordinated using Chinese medicine material and sodium acid carbonate, citric acid, lysine, g- aminobutyric acids, fructooligosaccharide and wheat bran
Use, effectively alleviate heat stress of the pregnant sow under hot environment, improve the anti-heat stress ability of sow, also,
Chinese medicine material used belongs to pure natural raw material, quality-high and inexpensive, noresidue.
2. the anti-heat stress feed additive for adding 0.1-0.3% by weight percentage in mixed feed can
