Whether it is a feed additive, a management practice, an equipment purchase or a whole myriad of inputs for your dairy, you are faced with choices. But which of the choices is the best investment? How do you know?
It is jokingly said that if you feed multiple products that all promise to improve milk production by 5 pounds, your cows should average 150 pounds of milk per day. Of course, we know this isn’t true, but how can we make decisions that offer us the best chance of financial return? How do you know if two products used together are additive in their response or if each negates the effect of the other?
