[QUOTE="BC, post: 725565, member: 67"] You really need to get your hay analyzed. 8 bags of cubes for the week = 400 lbs. Divide that by 7 days and you get a tad over 57 lbs. With 60 cows that is just under 1 lb per day of cubes. I assume you are feeding 20% range cubes. That 1 lb of cubes is supplying an additional .2 lbs of protein to the cow. Without a forage test, we don't know how much you need to be feeding. An 1100 lb cow in early lactation with average milk production needs 16.8 lbs of TDN and 2.9 lbs of protein. If the lactating cow is eating low quality forage (<52% TDN, 7% CP) she should be eating 2.2% of her body weight in hay (24.2 lbs) that supplies 12.6 lbs of TDN and 1.69 lbs of crude protein. Your low quality hay is shortchanging the cow by 4.2 lbs of TDN and 1.2 lbs of protein a day. If your cows are bigger then this amount will be even more, if they are smaller it will be less. This next summer, try to raise or buy some higher quality hay. It may cost more to raise or buy, but will be cheaper in the long run to feed. [/QUOTE]
