Description
Technical field
The invention belongs to the feeding methods before pig cultural technique field more particularly to a kind of insemination of sows.
Background technology
With continuously improving for pig cultural technique, pig-breeding structure is just towards scale, intensive, specialized cultivation
Pattern is fast-developing.Wherein, litter size is to weigh the important indicator of sow reproductive performance, improves sow the first-born litter size, helps
In the lifelong breeding achievement for improving sow.
The breeding of sow, the target with inter-species kind are bred in due course with the sow of body condition with herd boar with meeting with health
To improve pregnancy rate, the daily management for sow of weaning should focus on heat stimulation.After wean, breast can be swollen because of galactosis
It bulges and, when the secretion of milk is with holding balance is reabsorbed, suckling process will taper off.After wean 2-3 days, breast is swollen
Swollen reduction, celluar tissue start to decompose, while FSH (follicular stimulating hormone) stimulates Oocyte Development at ovarian follicle, and folliculus ovarii is tough
Band will quickly increase and start to secrete estrogen, prepare to receive fertilized eggs for uterus, and stimulate performance symptom of estrus,
Estrogen can promote the secretion of LH (lutropin), LH follicular development can be made at ovum, and accelerate to ovulate.This stage is boar
The important stage of management, effective breeding just determine farrowing as a result, wean influences farrowing index to breeding interval, also influence
Litter size.The management of gestation and nursery phase has a major impact wean to the interval of breeding of sow.
Pig farm sow is when being bred at present, since the heat situation of wean sow is poor or breeding means are unreasonable
And other reasons so that first breeding or unsuccessful for the breeding again of Suprapubic arch sling, long-term nonpregnant sow proportion
Greatly, added cost is fed, there are larger economic losses, and additionally, due to that cannot breed in time, the farrowing rate on pig farm can be by very
Big to influence, economic benefit is difficult to improve, to be unfavorable for the development on pig farm.
It is presently used for before breeding in the daily ration of sow nurturing period, energy level and source can significantly affect the first feelings of sow
Phase starts, the quality of Oestrus rate and egg mother cell.It has been investigated that high-energy level remarkably promotes Insulin, IGF- in blood
The secretion of 1 and Leptin increases the secretion frequency of LH, therefore the Oestrus rate and ovulation rate to improve sow increase in daily ration
Add fat content that can improve triglyceride and total cholesterol concentration in blood, and E2 is promoted to secrete, is conducive to sow puberty
Start；And increase content of starch, as energy level improves, large follicle number increases, and IGF-1, E2 concentration increase in liquor folliculi, then
Be conducive to the maturation of egg mother cell.
Therefore, for the sow before breeding, a kind of feeding that can greatly transfer oestrus of sow stimulation and breed of exploitation in due course
Material, feed addictive or feeding method, successfully breed to primiparity and Suprapubic arch sling, improve the pregnancy rate of sow, namely
Becoming pregnant for sow has conclusive influence, the pregnancy rate for how further increasing sow significant live pig production.
Invention content
It is an object of the present invention to provide the feeding methods before a kind of insemination of sows, by feeding special feed, directly act on
In sow pituitary, internal reproductive hormone secretion is adjusted, to adjust the cyclostage of dam disorder, makes its normal heat.
The invention is realized by the following technical scheme：
A kind of feeding method before insemination of sows, carries out in accordance with the following steps：
1) 4-7 days before breeding：Groupuscule stable breeding feeds Early placental phase material, and 2.5% is added according to weight in Early placental phase material
The feed addictive used before insemination of sows, daily every scale of feeding 1.6-1.8kg, feeding 3 times daily, 10:00-11:00 raises
Feed day total feed amount 1/2,17:00-18:The 1/3,21 of 00 feeding day total feed amount:00-22:00 feeding day total feed amount
1/6；
2) 0-4 days before breeding：Groupuscule stable breeding feeds Early placental phase material, and 3.0% is added according to weight in Early placental phase material
Standby feed addictive, daily every scale of feeding 1.8-2.0kg, feeding 3 times daily, 10:00-11:00 feeding day total feed amount
1/2,17:00-18:The 1/3,21 of 00 feeding day total feed amount:00-22:The 1/6 of 00 feeding day total feed amount；
The feed addictive used before the insemination of sows, is prepared by the following preparation method：
(1) feedstock processing：By fresh prematurity Siraitia grosvenorii, the Siraitia grosvenorii fallen, the villus on removal Siraitia grosvenorii surface；
(2) Subcritical Water Extraction：The raw material that upper step is obtained, is smashed, and the deionized water of the weight such as addition carries out subcritical
