A piglet usually feeds from its mother until it is four to six weeks old and weighs about 25 pounds. Then it begins to eat feed grain and is known as a feeder pig. It takes about six months for a pig to reach market weight of 250 pounds.
People also ask, how much weight do you lose when you butcher a pig?
On average about 57% of a hog make it from the pen to the pan. A 250 lb. hog will yield approximately 144 lbs of retail cuts. Around 28% of a hog's live weight is inedible product re- moved during the slaughter and dressing procedure bringing our 250 lb.
How many times can a pig get pregnant in a year?
Pregnancy lasts for 3 months 3 weeks and 3 days. A well fed sow will produce at least 10 piglets (litter) from each pregnancy and may have 2 litters each year. After studying this unit you should be able to: 1 Care for the pregnant sow.
Pigs in winter do not need any type of supplemental heat down to at least 20 degrees below 0 Fahrenheit, which is how cold it has been here. We've actually looked into their three-sided shelter and seen steam rising off their bodies on cold days.
The pigs were processed at home, so there was no cost for slaughter or butchering, but slaughter generally costs about $60 plus another $100 for butchering. Finished hanging weight was approximately 150 pounds per pig, which means about $2.50 per pound hanging weight.
A 40 pound pig, around 8 weeks of age, should be getting 1 – 1 1/2 pounds of 17-18% protein in a pelleted starter grower feed, per day. At around 75 pounds, 12 weeks of age, up the feed to 2 1/2 – 3 pounds of 15% protein feed mix. At 125 pounds, or 16 weeks, up the feed to 4 – 5 pounds of the same feed per day.
Gimme Shelter. Pigs require very little space. While textbooks say pigs can get by with a minimum of 20 square feet per pig in an outdoor area, they need more room to roam. Plan for a minimum of 50 square feet per pig, preferably a little more.
-A pig will eat an average of 6 to 8 pounds of feed per day. In our case the feed is an unmedicated mixed ration of corn and soybeans. -After four to six weeks of feeding from its mother, an average pig will eat roughly between 700 and 900 pounds of food (depending on many factors) until finish weight.
A sow stays pregnant an average of 114 days, although it's not uncommon for pigs to lose their babies before they are born, or have one or more stillborn piglets. She might not look pregnant until about three weeks before she delivers, but that doesn't mean there's a problem with the piglets.
Unlike laying hens (kept for egg production) which live for about a year, broilers only live for several weeks before they are slaughtered. In the EU, the slaughter age ranges from 21 to 170 days (typically around 5 to 7 weeks)6.
If you want to pasture pigs you first need to realize how much space you need per pig. In “The Homestead Hog” it states that 25-35 pigs per acre is a good rule of thumb. I use the lower figure of 25 per acre just to be safe and give them a lot of room to root. This means that you can put 8-9 pigs on a ¼ acre.
Feed is your biggest cost. Our pigs have tended to have a feed conversion ration of between 2.5 and 3. That means it takes us 2.5-3 pounds of feed to grow one pound of pig. This year (2014) we're buying our feed for $15 a 50 pound bag.
Store also carries charcoal and lighter fluid, roasting pans and several flavors of sauces. Price of whole pigs varies by size: 20 to 30 pounds, $3.29 per pound; 60 to 70 pounds, $2.19 per pound; 80 pounds and up, $1.99 per pound.
Most pig farmers buy “weaners,” piglets about two or three months old that are no longer reliant on their mother's milk; they then raise the pigs to slaughter weight (typically about 250 pounds), which on factory-style farms is attained by the time they're 6 months old.
The highest quality beef comes from animals that are under 36 months of age. Old cows produce highly acceptable beef if properly fattened and processed. Depending on the calf and the feeding regime, calves are best slaughtered between three and 16 weeks of age.
At the time of the sale, market swine will weigh between 200 and 280 pounds with an average weight of 265 pounds. Market pigs sell for between $2.00 and $4.00 a pound with an average price of $3.50 per pound.
Mating the Sow. Obviously enough, the first step toward rearing healthy piglets is making sure the intended mother is mated! A gilt (a young female hog) should reach sexual maturity at five or six months of age, and be receptive for two or three days of each subsequent 21 day cycle.
- Berkshire. The third-most recorded breed of swine in the United States, Berkshires are known for fast and efficient growth, reproductive efficiency, cleanness and meat flavor and value.
- Chester White.
- Poland China.
The gestation (pregnancy) period of the female pig is 114 days. She will be ready to be bred another time around 5-7 days after her pigs are weaned (removed from nursing). Thus if you wean the litter of pigs at 21 days of age she will come into estrus (heat) around 26-28 days after farrowing (giving birth).
A female pig can become pregnant at around 8-18 months of age. She will then go into heat every 21 days. Male pigs become sexually active at 8-10 months of age. A litter of piglets typically contains between 6 and 12 piglets.
Most piglets are delivered every 15-20 minutes, but can occur faster or slower. If the interval between piglets is longer than 30-45 minutes, then the sow or gilt needs to be evaluated to see if she is having difficulty having her piglets.
Sows are first mated when they are 6-8 months old. Around 80-90% of sows in the UK are serviced by artificial insemination (AI). Pregnancy lasts 4 months and a sow will give birth (farrow) to 5-25 piglets in a litter (averaging 10-12).
The average interval between birth of pigs is approximately 15 minutes but can vary from simultaneous to several hours in individual cases. Use of oxytocin to speed up rate of delivery is helpful if correctly done and if farrowing is proceeding slowly but otherwise normally.
