I have a York barrow that shows in 30 days. He currently weighs 260. Max weight is 290. What suggestions do you have for holding and keep fresh?

Sorry just saw this. Powerfill.

Total daily feed; divide into 2 equal neals:
Powerfill 3 lb
Depth Charge. 8 oz

Pig should it is gain 1 lb per day.

Or, if the pig has some extra fat:
Total daily feed; divide into 2 equal meals:
Fitter 35. 3 lb
Depth Charge. 8 oz

Pig should gain 0.3 lb per day. After 10-14 days add Heavy Weight at 6 oz per day.

The pig should gain about 0.9 to 1 lb per day.
