ii) Herd size distribution
• 9% of herds have 750 or more cows
• Herds with between 700 and 749 cows have highest production per cow
A little under fifty percent (5,677) of herds have between 150 and 349 cows (Table 2.4). In 2010/11, 6,201 herds (53%) had 300 or more
cows, 2,828 (24%) had 500 or more cows and 454 (4%) had 1,000 cows or more. Averages of milkfat, protein and milksolids per cow, by
herd size, are also included in Table 2.4. Average milksolids per cow varies between 247 kg (herds with 50-99 cows) and 359 kg (herds with
700-749 cows). A decade ago (2000/01) only 26% of herds had 300 or more cows and 7% had 500 or more cows. Compare this to 2010/11,
when the numbers were 53% and 24% respectively.
