[QUOTE="plumber_greg, post: 798588, member: 9115"] I usually keep 10 or 12 replacements each year. So, about 10%. One of my criteria for selectment is that they are born on the first heat cycle. What I have noticed is the fertility of the herd increasing. If a cow is open she sells. It seems that if a cow makes it to a 4 year old she'll last out. Last winter in 34 days of calving, if I remember right, I had all but 11 calves on the ground. One argument for keeping replacements. gs [/QUOTE]
