Philip has 20 cows.
He has 50% more ducks than cows, which means he has 20 * 0.5 = 10 more ducks than cows.
So, Philip has 20 + 10 = 30 ducks.
He also has as many pigs as one-fifth of the total number of ducks and cows.
The total number of ducks and cows is 20 + 30 = 50.
One-fifth of 50 is 50 / 5 = 10.
Therefore, Philip has 10 pigs.
The total number of animals on Philip's farm is 20 + 30 + 10 = 60.
#### 60
The answer is: 60
