Reproductive efficiency is one of the most important parts of your herd’s success. Ensuring you aren’t feeding animals that are not able to produce is integral to maximizing your farm’s profitability. Making sure each spring that your bulls can get their job done is arguably even more important – finding out the majority of your cows are open in the fall is a costly way to learn you have a sub-fertile or infertile bull. Changes in an animal’s productivity can occur suddenly and at any time, and your bottom line relies on reproductive success, which is why annual testing is essential to maximizing your returns.
