is an example of the pre-slaughter withdrawal time: |
|
|
|
|
|
|
|
|
|
|
| Use
of a drug with a five-day pre-slaughter time is discontinued at 9 a.m. on
Friday. At 9 a.m. on Saturday, the
treated animals have completed their first withdrawal day. |
|
|
| The
fifth withdrawal day will end at 9 a.m. on Wednesday. |

are two illustrations of how milk discard times should be calculated. One shows the milkings and the other milk
