[QUOTE="MikeC, post: 153600, member: 1604"] Your scenario is not considered "Feed Conversion". The maintenance requirements of larger cows is higher than smaller cows but unless they weigh twice as much as yours it shouldn't be 50%. Example: 1-A 1000 lb nursing cow needs 20.2 lbs of Dry Matter and 2 lbs of protein per day. 2-A 1200 lb nursing cow needs 23 lbs. of Dry Matter and 2.1 lbs of protein per day. That's a difference of; Approx 13% MORE Dry Matter Approx 5% MORE Protein If the hay costs are .03 cents per lb.($30.00 for 1000 lb roll) and the larger cow eats 13% more hay than your cow (30 lbs. per day) it would mean the larger cow eats 4.5 lbs per day more hay. 4.5 lbs X .03 cents =.135 cents per day X 205 = $27.68 more for the 205 day calf period. If he raises 50 more lbs. of calf than you he is coming out well ahead of you if calves are bringing $1.00 per lb. In fact $22.32 more per calf. This proposition might not fit your case exactly, but there is a place for larger framed cows in the right environment. [/QUOTE]
