KiWi Cross

Frank Buckley's Moorepark 5 strain trial:
Five 100 cow herds of different breed types were compared, the Kiwi cross herd showed €17k higher profit than the pure HF herd, allowing for zero bull calf prices and low cull cow prices.
The Norwegian Red X herd showed €10k more profit than the HF.
Frank calculates that cross-breeding is worth an additional €200 EBI points per cow and Cross-bred cows last one lactation longer than HF cows.

Frank's conclusion:
The results indicate that with a fixed land base and across 3 milk price scenarios Jersey and Norwegian Red cross-bred dairy cows can offer immediate substantial improvements to farm profit.
This is particularly true with the KiWi cross due to a combination of improved fertility/survival and improved milk receipts.
In the analyses presented KiWi cross cows increased farm profit by €16,023, €14,089 and €17,796 compared to Holstein-Friesian cows at base prices of 27 c/l, 20 c/l and 33 c/l, respectively.
In addition, the results highlight that losses resulting from reduced cull cow and male calf value are clearly overshadowed by the overall performance of the KiWi cross.

Jersey Efficiency

Frank Buckley's 2009 Moorepark trial comparing bite rate and feed intake differences between Jerseys with HF showed that Jerseys are 32% more efficient than HF at converting grass into kgs Fat/Pr.
