For every 2 cows, there is 1 bull. Therefore, there are 4 bulls on the farm (since 8 cows ÷ 2 cows/bull = 4 bulls).
Since there are 8 calves for every 1 bull, there are 32 calves on the farm (since 4 bulls × 8 calves/bull = 32 calves).
The entire farm has 8 cows + 4 bulls + 32 calves = 44 animals.
So the percentage of calves in the entire farm is (32 calves ÷ 44 animals) × 100% = 72.73%.
Therefore, 72.73% of calves compose the entire farm.
