Q

This process has typically induced anywhere from 20-40% of females within a 10-20 day period

A

Induction

22
Q

It is common to begin induction using what?

A

Once daily fenceline
Once daily physical exposure to a mature boar

23
Q

Induction start at what days of age ?

A

160-180 days of age

24
Q

Exposure of boar to gilts allow for how many minutes?

A

30 minutes each day

25
Q

In higher level of boar exposure Boar is moved into a gilt pen for many minutes?

A

15-30 minutes

26
Q

This kind of boar are allowed to move freely through the pen

A

Vasectomized boar

27
Q

This boar must be controlled to prevent breeding of estrus gilt.

A

Intact boar

28
Q

Is beneficial as it allows for more chances to identify fertile and non-fertile females

A

Early puberty induction

29
Q

Will be marked and perhaps allowed to cycle at least once more before breeding

A

Fertile females

30
Q

will be identified as early as possible to minimize any further feed costs and loss of market value from

A

non-fertile gilts

31
Q

Estrous cycle of sow

A

18-24 days or an average of 21 days

32
Q

Called the estrus or heat period lasts from 2 to 5 days

A

Period of sexual receptivity

33
Q

Sign of period of sexual receptivity

A

Swelling and reddening of vulva
Thick mucus discharge from the vulva
Mountain other animals or willingness to be mounted by others regardless of sex. Also assumes characteristics mating position when touched on the back by a boar or caretaker
Restlessness or grunting
Reduce appetite
Attempting to urine with very little urine at all
Difficult to be moved or transfer in the presence of boar
React to boars mating sound

34
Q

Approach the animal from behind and apply pressure on her sides with both hands.

A

Back pressure test

35
Q

Ride on or press the back or loin of the female.

A

Teaser boar method

38
Q

Behavior or sexually receptive sow in teaser boar method

Cocked ears
Willingly submit caprices of the male

39
Q

Techniques in heat detection

A

Back pressure test
Riding the back test
Semen on snout method
Teaser boar method
Examination of external signs of estrus and records

40
Q

The prime objective in feeding the future breeding stocks

A

For them to reach their reproductive maturity at right weight and age

41
Q

Should be kept from getting too fat

A

Breeding gilts

42
Q

About 10-14 days before the gilts are serve, the feed allowance is increased to how many kgs?

A

3.0-3.5 kgs/day

43
Q

This aims to increased ovulation

A

Flushing

44
Q

Quarantine measures

A

All arriving or newly purchased replacement gilts or boar should observe animals for any disease or untoward reaction for at least 2 weeks
Replacement animals should be introduced and acclimatized to the normal microflora of the farm

45
Q

Replacement animals should be introduced and acclimatized to the normal microflora of the farm by?

A

*Introduction of the fecal material inside the pen taken from older stocks
*Contact with older animals like board and sow
*Feeding with small amount of chopped placenta, aborted piglets or intestines or intestines of piglets which died from diarrhea
*All this practice would improved the resistance of the animal and coming litter against common disease affecting the farm such as mastitis or diarrhea
