iii) Breed averages
• Holstein-Friesian and Crossbreed cows show highest milksolids (kg) production
Herd test statistics by breed (Table 4.6) include cows herd tested four or more times during the season.
On average, Holstein-Friesian/Jersey crossbreed cows produced a higher volume of milk and more milkfat than other breeds, while
Holstein-Friesian cows produced more protein. Jerseys have the highest milkfat and protein percentages. In the Holstein-Friesian breed,
five-year-old cows produced more milksolids than any other age group. Five-year-olds also dominated production for Jerseys and Ayrshires,
while six-year-olds had the highest production for Holstein-Friesian/Jersey crossbreeds.
A crossbreed is defined as having at most 13/16 of any one breed. For example, a Holstein-Friesian/Jersey crossbreed may be 13/16
Holstein-Friesian, 2/16 Jersey and 1/16 Ayrshire.
