Consulting Officer survey data from 198 owner/operator dairy farms for
the 1991/92 season was analyzed. Trends in income, farm costs and
profitability at changing levels of milkfat production/ha were examined.
Increases in milkfat production/ha were associated with increases in stocking
rate (Rū=0.29) also tended to increase but at a slower rate. An increase in
milkfat production/ha was generally associated with an increase in EFA/ha
(Rū=0.58). On individual farms at similar levels of EFS/ha there was
considerable variation in milkfat production/ha. Implications for future
research are discussed.
