BreedingCurrent Lecture- Pigs won’t overeat, eat when they’re hungryo Give carbs & protein and will balance out diet- Pig: swine- Farrowing: giving birth- Gilt: male un-castrated- Boar: male un-castrated- Sow: female after farrowing- Barrow: castrated maleo Remove the effects of testosterone o Testosterone distributes through meat (Boar Taint) - Breed a boar to a sowo 114 days gestation o 3 months, 3 weeks, 3 days- Pubertyo 4-8 months - Breedo Wait for 3rd heat cycle Pig is more mature - Estruso 1-5 days (20-30 hours period heat)- Estrouso 21 daysThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.- Breed in morning & afternoon- Farrowing o 10 pigs per littero Can save 1 pig/littero 1 will come out backwards- Pigs can be aggressive- #1 cause of death in baby pigs: crushing by mother - Clip umbilical 3 inches asap & dip in iodineo Very quick to get up & move- Breach birth (when a pig comes out upside down) get involved with & save- Farrowing crate o Continue sow for limited amount of time (3 weeks)o To prevent crushing o Walk right in/only during birth - Gestation crateo Entire life in solitary confinement o Can fit a lot of pigs in a small spaceo Do not need to give up profit to this level o Strictly for breeding - Breed pigso Do not leave boar w/ pig bc aggression o 110 days bring into farrowing crate o Utter swell, vulva large, wiggle tail do not feel o Prior to giving birth drip milko Less than an hour: from start to finish (including afterbirth) o Fat sow hard time giving birth 1. Clip umbilical to 3 in & dip in iodine2. Put underneath source- migrate back to momo Anterior teats (fronts) more productive  Larger pigs go to themo Smaller pigs got to back teatso Little pigs & heavy pigs have less chance of survival - Piglets do not do well nursed by humans- Larger piglet is put under more stress to come out - 3 pounds ideal weight3 poundsSurvivabilityWeight- Breach birth human present, can save babieso If sow is aggressive-leave alone- Pass 2 afterbirth o 1 horn passed o Give birth againo Pass another - One day of life… get accustomed to mom - Give shot of oxytocin cleans out uterus if needed- Stillborn not uncommon- If she doesn’t pass afterbirth will die quickly3. Next day give iron shot (baby pigs born anemic)o Survive in wild: root around in soil o 1 cc of irono W/o will die b/c they do not get sufficient iron from mom 4. Tail dock (not at Peckham) o Baby pigs interactive, tail biting may lead to secondary infection o Dock at ¾ an inch5. Remove needle teeth (4 sets of them)o Born w/ large pointy teetho In wild: they’re used to indicate to mom to drop milk (oxytocin kicks in)o Can injure sow & other pigletso Domestic pigs teats are sensitiveo Wild teats are desensitized from running through the brusho 3 weeks old, they fall out anyway6. Ear notch (for identification purposes) o They’ll rip out tags o Add up o Max # on left 80o Does not stress out animal to look at its tags- Sows have different tones and she talks to her piglets- Certain breeds are more adapt to mothering than others, you can tell when you have a good mother pig, she will be gentle around her piglets to prevent crushing- Can breed in good mothering skills - Overview of processing the litter…1. Clip umbilical cord (3 in) ASAP and dip in iodine a. This prevents infection 2. Put underneath heat sourceThe next day…3. Give iron shot a. Baby’s are born anemic 4. Tail dock if applicablea. ¾ inch5. Remove 4 sets of needle teeth 6. Ear
