In a controlled trial, cattle showed varying live weight gains, with certain cattle initially appearing as the superior choice for breeding based on their substantial weight increases. However, an intriguing pattern emerged upon reviewing the Pasture Feed Intake data.

Despite being previously overlooked due to lower overall weight gain, specific cattle displayed remarkable feed efficiency— that is, they consumed significantly less pasture for each kilogram of weight gain. In contrast, some of those with high weight gain had a disproportionate intake, necessitating much more pasture for the same weight increase. This feed efficiency metric is crucial for sustainable farming: efficient cattle require less feed, allow for higher stocking rates and enable better pasture management. Additionally, they produce less methane, a win for both productivity and sustainability.

The power of this study lies in the genetic aspect of feed efficiency. Selecting more efficient animals for breeding promises not just immediate gains in resource management and sustainability, but it also secures a lineage of cattle that will continue to thrive efficiently, providing future benefits. This case study advocates for a data-informed approach to breeding, ensuring productivity and environmental stewardship go hand in hand.
