Guidelines for Feeding a Heavy Muscled Pig

Starting Plan (First Two Weeks): 

Evaluate Muscle: 

  • If extremely heavy muscled pig, start on 685
  • If typical heavy muscled pig, start on 632

Typical starting ration for an extremely heavy / heavy muscled pig, per feeding: 

  • 1 pound of 632 (or 685 for extreme ones)
  • 1/4 pound of Oat Groats

Evaluate muscle in ten days to two weeks and see if you need to adjust protein down more. Increase feed content by 1/4 of a pound as they eat it all. 


Growing Stage: 

Evaluate muscle throughout the entire period and make sure you don’t need to go down on protein more (686).

We suggest feeding more oat groats to very heavy muscled pigs. Feed a half pound per feeding to typical heavy muscled pigs and one pound per feeding to extremely heavy muscled pigs. 

Typical growing ration for an extremely heavy / heavy muscled pig, per feeding: 

  • 1 1/2 to 2 pounds of 685
  • 1/2 pound of Oat Groats or 698

Evaluate muscle and fat cover once a week through the growing phase to see if you need to adjust protein down more. Remember, along with protein, the amount of feed can also effect muscle and structure (more feed = more muscle).  We suggest to add fat by 120 pounds if needed by starting with 2 ounces of FULL FIGURE

Most pigs that are very heavy muscled also tend to be harder. Replace your Oat Groats with 698 Slop and rely on 698 to help soften their muscle and give them more body. 


Finishing Stage (Last 30-40 Days Prior to the Show):

Most very heavy muscled pigs will stay on 685. If you have managed muscle enough you may be able to add in a small amount of 611 to help with freshness and softness at the end. 

Typical finishing ration for an extremely heavy / heavy muscled pig, per feeding: 

  • 2 pounds of 685 (could replace possibly 1/4 to 1/2 pound with 611 if not too heavy muscled)
  • 1/2 pound of Oat Groats or 698
  • 2 to 4 ounces of FULL FIGURE
