Abstract. Feed costs can account for more than half of the total cost of a dairy farm, so selecting cows with more efficient feed consumption can reduce these costs and improve profitability. The Feed Saved Conversion Index (FSAV) measures the genetic ability of animals to save on feed as a result of better feed conversion. The higher the FSAV, the more efficiently the cow converts feed into milk. Research shows that feed savings are achieved by reducing residual feed intake (RFI), where cows with a negative RFI consume less feed than expected. Small breed cattle have been shown to be more efficient at converting feed into milk and body tissue, as measured by the Feed Conversion Index.
Key words: cattle, feed saving, feed conversion, residual feed intake
