Re:
where are you getting your numbers?
I don’t mean to give you a history lesson and I don’t have much time, so I will try to keep it short.
The 60 lbs per day intake per cow, both dairy and beef, was generated from around the great depression to the early 80s and it became the industry standard.
It was developed for our dumb and uneducated farmers, and I say that with all love and compation, who were the product of our lost generation.
It is/was a nationwide utopian number to cover all possible hardships while raising a cow for a period of one year including, but not limited to, drought and/or harsh winters.
It was developed to give our dumb and uneducated farmers, again with love and compassion, a starting point to know how much pasture and/or feed stock they would need to raise on their farm to feed a cow for one year.
Those who raised more feed stock then they needed either increased their herds or sold their surplus and the term cash crop was born which opened up a whole new industry called row cropping.
The 60 lbs per day is not cast in concrete and should be adjusted for the many variables, such as geographical location and management practices.
i.e.: If your management decision is not to hold food stock for a drought or hash winter because you are not in a drought or winter area, then the 60lbs per day should be lowered.
Re:
I have never heard of 60lbs for maintenance.
I’m not surprised as it has pretty well been cast aside to % of body weight.
Re:
I ran 12 mature cows in a dry lot last winter and put out one round bale, 1100lbs, every third day (30.5lbs per hd per day)
But you did not have them on dry hay alone for the entire year did you?
Did you give them any supplemental feedstock beyond the hay, such as pasture and or salt/minerals etc during the entire proceeding year so they could store fat and vitamins/minerals for the winter while only on hay?
If so, isn’t that all part of their total yearly intake?
Doesn’t grass have a higher moisture content and nutritional value then hay and therefore have a higher weight?
I am not being critical of the study, I am just pointing out it’s flaws as do all studies.
I believe the study has value but it also has flaws and those flaws need to be discussed and understood to determine its true value.
Thanks for your post and interest
