The dataset created for the Feeding the Genes project was used to estimate the extent of phenotypic responses in yield from daughters of Holstein sires that differed by +50 units in Australian Profit Ranking (APR). A subset of 77,144 cows born from 2005 to 2009 was used to compare sire selection patterns in herds with different feeding management systems. APRs varied widely between sires (-303 to +430) with 20% of cows being daughters of sires with negative APRs. The average APR of the sires of the enrolled cows was only 68 with an average annual increase of 10.1 APR units. The highest APR average (77) and annual rate of APR increase (13 APR units/ year) were in the herds with the greatest reliance on pasture and feeding <1,000kg grain supplement in the bail (Low Bail), whereas the lowest equivalent figures (APR average of 48 and 7.8 units/ year) were in herds feeding total mixed rations (TMR). These results indicate that low APR sires had been widely used in the enrolled herds irrespective of feeding management system with major differences in sire selection patterns associated with the different feeding systems.
