Description
Technical field
The feeding that the invention belongs to be used before pannage technical field more particularly to a kind of insemination of sows that can improve Oestrus rate
Feed additives.
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 due to galactosis
It bulges and, when the secretion of milk keeps balance with reabsorbing, 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 folliculus ovarii is tough into ovarian follicle
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), and LH can make follicular development into 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, so as 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
The quality of phase startup, 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, so as to improve the Oestrus rate of sow and ovulation rate, therefore, increases in daily ration
Add fat content that can improve triglyceride and total cholesterol concentration in blood, and E2 is promoted to secrete, be 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 sow pregnancy rate namely
Becoming pregnant for sow has conclusive influence to live pig production, and the pregnancy rate for how further improving sow is significant.
Invention content
It is an object of the present invention to provide the feed addictives used before a kind of insemination of sows that can improve Oestrus rate, directly act on
In sow pituitary, internal reproductive hormone secretion is adjusted, the cyclostage of sow is adjusted, promotees its heat.
