When is a boar ready for breeding?

Factors Affecting Sexual Maturity

period intervening between two (2) successive heat periods in the absence of pregnancy.

Estrus cycle ranges from?

Also known as heat period

Estrus period last?

Time during which the sow will accept the boar (sexual receptivity)

Estrus or?

Produces GnRH

GnRH

LH

CL

FSH

Phases of Estrus cycle

building-up phase. -the ovarian follicle (under the influence of FSH and LH) enlarges and begins to secrete estrogens.

reddening of vulva and mucus discharge

sexual receptivity

mark the end of estrus (if pregnant)- CL is actively producing progesterone (if NOT pregnant)-uterus produce prostaglandin, procedes to diestrus

CL recedes and new follicle developed -short period of inactivity

long period of inactivity

It should be done on a routine basis. For best results, this activity should be done twice each day preferably early in the morning and late in the afternoon.

It is the method by which a pig raiser determines whether a sow will accept service by the boar.

Techniques of Heat Detection

This method is done by applying pressure on her sides with both hands. If she is receptive, she will just stand firm and rigid, ready to be served.

This is done by riding on or pressing the back or loin of the sow. Just like in the first method, the sow will stand firmly and remain rigid, ready to be served if it is sexually receptive.

With this technique old semen sample is squeezed from a squirt bottle on the snout of the sow.

A vasectomized boar is the best animal to use in this method. The boar is allowed to mount the sow.

Mating System

the secretion of milk from specialized glands (mammary glands) to provide nourishment to offspring. Last about 4-6 weeks (28-42 days), Involves production of hormones Prolactin (Milk Production) and Oxytocin (Milk Let-down)

Lactation last about?

Prolactin

Oxytocin

the time interval from weaning to service This is the time when the sow is unproductive.

Ideal dry period

Gestation period of swine

Factors to Consider in the Construction of Swine Housing

Below are the various swine housing system that you may adopt depending on the choice of your production operation.

In this system, the sows are removed when the piglets reach weaning age. The pigs remain in the same building from farrowing until they reach the desired weight for slaughtering.

The sows and piglets remain in the farrowing house until the piglets are weaned. The weanlings are transferred to a growing-finishing house.

The sows and piglets remain in the farrowing house until weaning. The weanlings are moved to a nursery house and finally to a growing-finishing unit where they stay until they are ready for slaughter.

The sows and piglets remain in the farrowing house until weaning. After weaning, piglets are moved to a nursery house, then to a growing house and finally to a finishing house until they are ready for slaughter.

It is also called the feeding/lying box/stall. . Stalls and tethers are normally cleaner when the rear half of the floor area is slatted.

A housing system where a number of animals are grouped and kept in one pen. Group housing is done base on the classes of the pigs (sows, gilts, growers, finishers.)
