First set the dry cow rules for your farm
Every farm can set the rules for selecting cows for SDCT. Cows can get a dry cow tube if 1 or more SCC values are over 200, or 2 or more SCC values are over 150, and so forth. You can also set your preferred dry period for mature cows and first calvers.
- To get your herd’s due to dry list go to Overview on the Home screen, you’ll see Due to dry on the Jobs list.
- To set the targets for your herd, click the settings icon to the right of Due to dry. The screen below will open.
- To use the SDCT logic (which is optional), put a tick in the box below for SDCT.
- The key data for SDCT cow selection is the SCC values in the milk recording results
- HerdApp also uses the cases of mastitis recording since the last calving
Then you can view the list of cows to dry
- When you click on the Due to dry row in the Jobs list, you will see the screen below
- Ok (in green in the SDCT column) means teat sealer only is recommended.
- Drug (in red in the SDCT column) means a dry cow tube is recommended.
- You can view the body condition score (BCS) value when drying off a batch of cows and perhaps give cows with a low BCS a longer dry period.
- Once the cows have been dried off, the drugs and dry off dates can then be recorded in a batch screen for speed of data entry.

- The colour coding explained when showing SCC values on HerdApp…
- Green, Health Cows. the last two tests were below the SCC target value set.
- Blue, Recently Cured, the cow’s last SCC has below target and the previous SCC was above target.
- Orange, Recently Infected, the cow’s last SCC has above target and the previous SCC was below target.
- Red, Persistently Infected, the last two tests were above the SCC target value set.
