mikei, hogs as well as other animals will tend to eat about 3% of their body weight per day as adults, and more like 5% as juveniles. If a 200 lb hog is given free reign in a field of grain, he can eat several pounds in a night by himself. That is on top of any other damage being done elsewhere, rooting, etc. At last count, Pig_Popper and I have taken 33 hogs from this property since early April, usually going once a week. Now, we can't see a lot of the hogs when we are hunting because they are hidden by the oats, so we have mostly taken larger hogs. I am going to be conservative and say the average size is 150 lbs. We have had a lot around 200 and one that was 270 and one that was 300 lbs. We have had some smalls as well, but you get the idea. In short, we have killed nearly 2.5 tons of hogs. Those 33 would be eating roughly 149 lbs of food per day (assuming all were adults, conservative estimate) and much of that would be coming from this field. So they could be eating literally hundreds of pounds of grain per week from this field.
