7.5 months or 225 days old
how many wieghts for a gilt to bred?
120- 130 kg.
T or F : the more the heat periods a gilt had before breeding, the more eggs she ovulates & the larger the litter farrowed.
TRUE
Ovulation in the swine increases progressively from one heat period to another until how many heat when the gilt is one year old?
5th heat
Sows & sexually mature gilts normally undergo periodic heat periods which last from?
18-24 days or an average of 21 days
the period of sexual receptivity called the estrus or heat perio last from ?

5 techniques in heat detection
- Back pressure test
- Riding-the-back test
- Semen-on-snout-method
- Teaser boar method
- Examination of external signs of estrus & records
prime objective of feeding:
It’s for the future breeding stocks for the to reach theor production maturity at the right weights & age. so that breeding gilts should kept from getting too fat or too thin.
about 10-14 days before the gilts are served, the feed allowance is increase to 3.0 - 3.5 kgs/day. what term is used for this sudden increase of feed allowance.
FLUSHING
about how many kgs/day should be given in flushing?

QUARANTINE MEASURES:
all this practice would improved the resistance of the animal & coming litter against common disease affecting the farm such as mastitis and diarrhea
- newly arrived gilts and boars should at least be quarantined for 2 weeks
- replacement animals should be acclimatized to normal microflora of the farm
- introduction to the fecal material inside the pen taken from older stocks
- contact w/ other animals (BOAR AND SOW)
- Feeding w/ small amount of chopped placenta, aborted piglets or intestines of piglets which died from diarrhea .
in 14-7 days before breeding once breeding this vaccination should be given.
