Show cattle AI is critical if you want to be competitive. Judges tend to reduce scores for mature aged show heifers that are not bred. Since show cattle tend to represent the highest investment, it's common to use AI in an effort to increase the genetics of the calf. AI semen is typically only collected on the best bulls making it the least expensive way to introduce superior traits into a herd. With this in mind, the AI process is important to the average breeder that needs to have successful AI of their heifers.
