Joe Sheehy: 40% AI-bred heifers offers massive potential

ICBF data shows a significant increase in AI dairy breeding over the past five or six years.

Up until then, there were only 16 AI-bred dairy heifers per 100 cows each year.

For the past few years, many of the top farmers have been setting a target of 40 AI-bred heifers per 100 cows, to allow for expansion, culling and the sale of surplus stock.
