The Dairy Podcast Show Dr. Kent Weigel: Dairy Efficiency Through Genetics | Ep. 16
Genetics can be a powerful tool for improving the efficiency of dairy herds, so it is vital that we keep up with the latest advances in genetic trait selection. With that in mind, there are two questions that are key. Firstly, what exactly are the right traits that improve efficiency? And secondly, what has been done so far, and what are the next steps in our selection programs? In this episode, Dr. Kent Weigel discusses what traits we can use to improve efficiency, how we can measure them, and how we are currently dealing with the evaluation of more complex traits – like resilience. Additionally, we talk about the future of our dairy students. How are researchers dealing with the fact that there are less kids who are interested in animal science? How do we keep our dairy scientists engaged in dairy fields?
“We started taking a look at my arrival in this field, as a scientist. It coincided with a time when people said 'let's not just make more milk, let's try to improve the fitness and functionality of the cow through genetic selection.'” – Dr. Kent Weigel
