[QUOTE="kyblockhead, post: 276333, member: 3603"] There are a lot of cooked (low moisture) tubs sold but I guess I can't understand the math. I looked at a Crystalyx Super Mag tub that was 12% protein. I sent a sample off to a lab and the TDN was 56.8%. That tub was sold by my local dealer for $113/250# and didn't include the $8 tub deposit. Most forages around here can carry a pregnant cow pretty well but starts to have problems when they calve and try to get them rebred. That means the cow's requirements goes from about 10 lbs TDN/day to 12-13 lbs TDN/day and protein goes from 2 lbs. to 2.5-3 lbs/day. I don't see how a tub that cows eat 0.5 to 1 lb daily will provide 1/2 lbs protein and 2-3 lbs. of TDN when it is only 12 to 20% protein and 57% TDN. The research I've seen says feeding a protein supplement will improve forage digestibility from 2 to 8% but will increase feed intake by 20 to 40% but protein had to be supplemented in the range of 0.5 lb/head/day for that to be accomplished. Cooked tubs just won't make that happen. Personally, if you have good hay and pasture a cooked tub may fill in temporary nutritional gaps but for most feeding programs they just won't provide enough nutrition. [/QUOTE]
