Q

–About 10-14 days before the gilts are served, the feed allowance is increased to 3.0-3.5 kgs/day. The aim is to increase ovulation. This means however that the heat cycle of the gilt (1st& 2nd) should be properly observed & recorded such that on the 3rd heat flushing can be implemented

A

Gestation period ( pregnancy period)

47
Q

Gestation period is the long period with breeding & ending with farrowing it. Lasts _____

A

114 days or 3 months, 3 weeks & 3days.

49
Q

Advantages of early pregnancy detection;

50
Q

PREPARATIONS FOR FARROWING

A

For the sow to be relaxed & to adjust to the new environment, move her from the gestating pen to the farrowing pen one week before farrowing

51
Q

Preparing the sow.

A

Thoroughly scrub with soap & water the region of the sides, udder & under surface of the body to remove adhering parasites that may cause diarrhea.

52
Q

SIGNS OF FARROWING
Nest making, nudging of hurdles, walls & flooring, biting of hurdles & guard rails
‘dog sitting’ position
Distension & enlargement of udder of the sow
Enlargement & swelling of the vulva
Small round size of sow is manure & frequent urination
Milk letdown – the sow is to farrow in 24 hours
Mucous discharge with meconium
Signs of labor
