Swine Management
2
Characteristics of swine
  • Pigs are Homeotherms
  • Maintain a constant body temperature
  • Pigs are Monogastrics
  • Pigs have very few sweat glands

3
Housing
  • Types of houses
  • Outside pen
  • A- frame houses
  • Open front buildings
  • Environmentally regulated buildings

Reproduction
  • Natural
  • AI
  • Heat period averages 2 days and occurs every
    20-21 days
  • Can synchronize gilts by putting them together
    and in a pen next to a boar
  • Lock up when in heat (Lordosis)

7
Reproduction
8
Reproduction
  • Boar penis is corkscrewed
  • AI rod has to be corkscrewed as well
  • Boar semen cannot be frozen
  • Shipped fresh overnight
  • 2 doses of semen are administered
  • 24 hours after 1st incidence of standing heat
  • 12 hours later
  • Done because pigs are superovulaters

9
Farrowing
  • Farrowing the act of parturition
  • Gestation period- 114 days (3X3X3)
  • Put into farrowing crates few days before
    expected parturition
  • Sows can have any number of babies
  • Wean at 21 days
  • Pigs are very susceptible to disease
  • Many farms are total confinment

10
Farrowing Crates
  • Used to protect the baby pigs from being crushed
    by the sow
  • Sow is confined in the middle so that she cant
    turn around
  • Equipped with feeder and watering device
  • Space on both sides of the sow for babies
  • Use a heat lamp to keep babies warm

Navel Cord Care
  • After birth excess navel cord is removed
  • Leave about 1 inch
  • Treat navel cord with iodine
  • Why?
  • Prevent infection

14
Clipping needle teeth
  • Born with only eight teeth
  • Fairly long and sharp
  • Can irritate the sow while nursing
  • Can remove these teeth to make more comfortable
    for the sow
  • We dont clip

16
Tail Docking
  • Pigs are normally in a confined space
  • Chew on others tail
  • Done out of boredom
  • To prevent tail biting and the possibility of
    infection, tails are docked
  • Dock were tail can barely touch the pigs back

18
Injections
  • 3 types of injections
  • Subcutaneous
  • Intramuscular
  • Intravenous
  • Two sites to give an injection
  • Neck
  • Ham

22
Injections
  • Iron is administered about 24 hours after birth
  • 1 cc of iron
  • Since pigs are in a create and dont have access
    to soil, iron- deficiency anemia can occur
  • Some people give a small dose of antibiotic
  • Give the sow penicillin

23
Ear Notching
  • Most used identification method for baby pigs
  • Removing a portion of the ear
  • The notches grow as the pig grows
  • Permanent identification
  • Litter and Pig
  • Litter - the pigs right ear
  • Pig - the pigs left eat

24
Ear Notching
  • Litter
  • Number of litter for the whole farm
  • Not for individual sow
  • Pig
  • Individual number for the baby pig
  • Has nothing to do with the rest of the farm

Castration
  • Removal of the testicles
  • Pigs are castrated if meant for slaughter
  • Meat from boars may have an odor when cooking
  • Takes testosterone out of the system, which makes
    meat tough

29
Castration
  • Best time for castration is between 1 and 14 days
  • Pigs are easier to restrain
  • Bleed less from the surgery
  • One person holds the pig by the back legs and the
    other person does the castrating
  • Make small incisions
  • Make sure to use some type of antiseptic spray

Parasites
  • Coccidia
  • Affects nursing pigs between days 5 and 15
  • Develop a yellowish, very fluid diarrhea
  • Infected pigs do not respond well to antibiotic
    treatment
  • Mortality rates will be moderate to high

35
Parasites
  • Worms
  • Roundworms
  • Nodular worms
  • Whipworms
  • Threadworms
  • Stomach worms
  • Lungworms
  • Kidney worms
  • Doesnt occur much in baby pigs

36
Weaning
  • Baby pigs are weaned at 21 days
  • Put in a nursery for a few weeks
  • Until pigs are 40 45 lbs
  • Moved to other pens for growing and finishing
