There is no solution.
If only odd numbers can be killed on each of five days, only an
odd number can be killed in total. 20 is even, so there is no
solution.
Expert:  RoberttheRocket replied 11 years ago.

This might sound a little silly, but it is a riddle, so I'd say do it like this:

Monday kill 5, Tuesday kill 3, Wednesday kill 1, Thursday kill 5, Friday kill 5, Friday Night kill 1. So you kill an odd number of cows during the five days in the daytime, and kill an odd number at night.
