How do you induce estrus in pigs?
Induction is a procedure used to advance estrus. Physical exposure using an intact or vasectomized boar provides the full range of stimuli. Hormonal injection in prepubertal gilts and sows with a combination also induces rapid follicle growth and estrus in 4 to 5 days.
What are the 4 types of swine operations?
Types of Swine Operations
- breeding and gestation.
- farrowing and Weaning.

What is artificial insemination in pigs?
Artificial insemination is the insertion and delivery of semen into the reproductive canal of a female pig (gilt or sow).
How do you make a pig go into labor?
To induce sows and gilts to farrow, inject them with a half-dose (1ml in the case of Lutaylse) 24-30 hours BEFORE you would like them to begin farrowing. Follow-up with another half-dose 6 hours after the first shot. You can expect about 96% of the sows injected with this protocol to farrow the next day.
What are the 5 primary types of swine operations?
Production of hogs has consisted of five different phases: farrow-to-wean, feeder pig or nursery, finishing, breeding stock, and farrow-to-finish.
What are the 4 stages of swine production?
The phases of pork production that take place on the farm to produce hogs ready for market are called: breeding-gestation, farrowing, nursery and grow-finish.
How are pigs artificially inseminated?
The general steps of AI are as follows:
- Detect standing heat as previously described.
- Clean the exterior of the vulva.
- Lubricate AI rod tip.
- Spread the vulva open with one hand and insert the AI rod into spread vulva at an upward angel.
When should you induce swine?
New recommendations suggest that sows should not be induced earlier than 2 days before expected farrowing to limit the percentage of immature pigs being born. The date of farrowing is determined from the first breeding day recorded as day 1.
How long can pigs be in labor?
The Birth Process. Duration of labor ranges from 30 minutes to more than 5 hours. Pigs may be born either-head first or rear feet first; either is normal. Fetal membranes or afterbirth may be expelled several times during delivery, but afterbirth generally occurs in a larger amount near the end of farrowing.

What is induced breeding of fish?
The artificial process by means of which the extract of the pituitary is introduced inside the body of both the matured male and female fishes, then the carps after being excited lay eggs in the pond water and subsequently fertilization takes place and the process is called induced breeding of fishes.
What is the difference between induced breeding and mixture breeding?
Whereas, in the induced breeding there is no possibility of mixture and as a result the pure form of fish seeds are obtained. ii) Desired species of carps can be cultured through the induced breeding.
What are the best management practices for reproducing pigs?
Allowing interaction between a boar and sow for estrus detection is still considered a best management practice among pig producers. Temperature, ventilation, aggression, body condition, and nutrition management are all very important aspects to proper care of the reproductive herd.
