Why I like to barr them...

so a question for yaw that do barr them for consumption.

at what age would yield the fastest weight increase by feeding 16% protein and adding in 99% veggie fat per 2 lbs of the 16% protein feed?

iv got some "pen raised" feral hogs about 4 or 5 months old right now and are segregated from the litter mates and are about 1.5x bigger than the rest of the shoats.

i put 2 aside, one blonde one for selective breeding to my next blonde sow and the other is just a normal red/brown hog, which will be for slaughter. he has actually put on the most wt. of the 2 and i was gonna barr him, just wanted to wait a bit (8-12 months) before cutting him and then maybe putting him in another pen and just pouring the fat and increasing his protein consumption from the 16% feed to around 40% by adding a portion booster of 24% protein. well i guess it would 40% if my math adds up correct, unless the 24% counteracts the 16%.

can anyone confirm or deny my math of getting 40% out of 16 and 24? and would barring him now yield the faster wt increase, or waiting till he is a yr or so?
