Why is feed efficiency a key trait in dairy cattle evaluation?

Feed efficiency is a key trait in dairy cattle evaluation primarily because it directly correlates with milk production levels. Cattle that convert feed into milk more effectively will produce higher volumes of milk, which directly benefits the dairy farm’s productivity and profitability. Feed is typically one of the largest expenses in dairy operations, so maximizing the amount of milk produced per unit of feed helps to improve economic returns.

When evaluating dairy cattle, a focus on feed efficiency allows producers to identify animals that can maintain or even increase milk yield while utilizing feed resources more efficiently. By selecting for improved feed efficiency, farmers can optimize their herd’s performance, leading to increased profitability over time.

The other options may relate to various aspects of dairy farming but are not as directly linked to the primary goal of maximizing milk output from feed consumption. While herd health, cost of feed, and reproductive success are all important factors in managing a dairy operation, they do not inherently measure the direct correlation of feed conversion to milk production.
