Feed conversion efficiency

With feed costs such a large proportion of variable and total costs on a dairy farm, it is important to measure the efficiency with which feed is converted into milk. Feed Conversion Efficiency (FCE) is a key measure of feeding system efficiency on a dairy farm, impacting on feed cost/unit of milk and milk operating profit. FCE is also an important factor impacting on a farm’s greenhouse gas emissions.

FCE should always be used in conjunction with other farm physical performance measures, and financial performance measures such as annual milk operating profit and return on assets. FCE is expressed in terms of the amount of milk produced per kilogram of feed given to your herd.

FCE can be measured for the milking herd on an annual basis, or seasonally within each year.
