[QUOTE="Son of Butch, post: 1493579, member: 14585"] No, as I did not see the study report, but read article reporting study which used NDSU newsletter as source. The author of article gave stats from study, but lack of detail left me as a reader with questions and assumptions. Rather than reading between the lines... I prefer to consider it as analyzing the data given. The heavier cows calves weighed 104 lbs more per calf (639 vs 535) indicating they produced more milk per hd. 47 1100# cows on same quality/tonnage pasture weaned 25,145 lbs vs 39 1400# cows weaning 24,921 lbs 25,145 - 24,921 = 224 lbs divided by 270 days = 0.83 total per day difference for the entire group .83 divided by average group size of 43 = 0.02 lbs per day which is a difference of only 1/50th of a pound/calf/day Which would indicate it took 47 lighter cows to produce the same amount of milk as the 39 heavier cows. Yes? No? Does that help? [/QUOTE]
