Pig raising costs
I too would suggest buying a pig from 4h or FFA program.
A weanling barrow or gilt will run 300 -500 dollars and weigh roughly 50 - 60 pounds. Show weights are typically 240 - 280. The cost to feed out a pig with quality feed is expensive. We feed Purina products and they are expensive , especially the supplements.
The supplements do not spoil the flavor of the meat , they simply add to the shape of your animal as show dates approach. Paylean has never been proven by the FDA or any other respected administration to effect taste. It is simply used near the end of the feeding period to loosen up tight muscled pigs and aids in appetite.
Other supplements , depth charge , heavy weight or fitter are used to shape and enhance pigs frame and build. For instance , if the pig is broad in the shoulders and rump , but has no middle , depth charge will help him expand in the belt and ribs. Heavy weight is simply a weight gaining supplement and fitter is used to hold a pig if it is in danger of exceeding show weight limit. It also , helps to tone a loose pig.
All being said , an animal raised for market show is better that a wild hog fed out. Corn has no real nutritional value other than fattening up a hog , much like a deer.
Pearland High School is having an Ag Expo on the 27th and 28th of this month. I believe there will be close to 100 pigs showing. I invite you to come out and see some awesome pigs and other animals as well. There will be an auction on the 29th. One could purchase a pig ready for slaughter , fed out with the best products available for 300- 500 dollars.
To answer your original question as to price , depends on how and what you feed. I have spent around 1500.00 this feeding period on my daughters barrow. I cannot put a price on the time we have spent together or the discipline she has developed during her participation in FFA.
Priceless in my opinion , she will graduate this year.
