Pig Farmer Math

Back by popular demand It's Farmer Math!!  OK, well it was suggested by The Farmer and my kids that we needed to start this again.  Yesterday,  while feeding cows the boys and I read through the posts and came up with the math questions.  I hope you enjoy them.  I hope you share them with your kids and grandkids.  Yes, farmers have to know a lot of math!  This goes with the reports from when the 4 Flat Aggie's went to 4 different pig farms in 4 different states, Iowa, Indiana, Minnesota and  Kansas.

1. The average litter of piglets is 11.  If a sow gave birth to 15, how many more did she have than the average litter?
2. If Flat Aggie watches 12 sows give birth and each sow has 12 piglets, how many piglets did Flat Aggie see born?
3. A hog barn can hold 1000 pigs.  Flat Aggie visited a farm that had 5 barns.  How many pigs could the farm have in all?
4. A pig weighs 60 pounds when it is moved to the finishing barn and it is there for 120 days.  It weighs 300 pounds when it goes to market at the end of 120 days.  What is the daily rate of gain for that pig? (How many pounds per day did it gain?)

Flat Aggie looked at a sow card and saw the sow had given birth to 14 litters of piglets.  The average litter size was 11.  The average baby piglet weighs 3 pounds.  

5. How many piglets has the sow given birth to?
6. How many pounds of piglets has this sow given birth to?
7. If 98% of the pigs make it to market, how many would that be? (Round to the nearest whole number)
8. If the above 98% weighs 300 pounds each, how many pounds of market pigs did that sow produce?
9. If the average pig carcass weighs 74% of the animal’s live weight, how many pounds of pork are the product of this sow?

1.)    4 piglets  2.)144 piglets  3.) 5000 pigs  4.)2 pounds per day  5.) 154 piglets  6.) 462 pounds  7.)  151 pigs  8.) 45300 pounds  9.) 33522 pounds
