Sim­ple steps min­imise herd in­fec­tion

Matamata Chronicle - - Rural Delivery -

One of the high­est-risk pe­ri­ods for herd in­fec­tion is at the end of the sea­son. It is a cru­cial time to set the farm up for the fol­low­ing sea­son. Dry cow ther­apy can re­ally make a dif­fer­ence.

You can min­imise the risk of in­tro­duc­ing in­fec­tion or run­ning into trou­ble with residues by:

Al­low plenty of time to treat your cat­tle and en­sure you have all the steps in place to cre­ate an in­fec­tion-free herd.

Treat your cows in man­age­able mobs.

Pro­vide ad­e­quate train­ing. A suc­cess­ful treat­ment pro­ce­dure and su­per­vi­sion are es­sen­tial.

Use dry cow ther­apy only at the cows’ last milk­ing. This is ex­tremely im­por­tant. To avoid con­tam­i­na­tion of milk bring cows back into the shed af­ter milk­ing to ap­ply dry cow ther­apy.

Watch for quar­ters that have al­ready dried off. Do not treat these as there is an in­creased risk of residue vi­o­la­tion.

Keep a log. Record cow num­ber, treat­ment and date for ev­ery cow.

Clear mark­ing can help you out. Mark your cows clearly so that a cow won’t be ac­ci­den­tally milked if it jumps the fence or the wrong mob is brought in.

Move your cows into clean pad­docks af­ter dry­ing off. Avoid ef­flu­ent or re­cently grazed pad­docks. Don’t bring your cows any­where near your shed for at least seven days af­ter dry­ing off.
