[QUOTE="zendog, post: 527780, member: 6830"] I am missing something here. If every dairy cow calves once a year, and have of the calves are female, and all females are replacement, that would mean that 1/2 of all dairy cows are replaced every year and the the average age of a dairy cow is 1 year??? Aren't dairy cows productive for 6 or 8 years? If all the female calves were kept, that would mean the dairy heard would double about every three years. I would also have thought that only the female calves of the most productive milkers would go into replacement. The goal for me is to get a small beef cow. The goal for the dairy farmer is to get a freshened milk cow, a low birth weight calve with fewer birthing problems, and easier sale at higher price for the born calf. [/QUOTE]
