Making the most of your RVM Consult

Making the most of your RVM Consult
George Watson, Veterinarian, Anexa Vets Morrinsville

As the 2020-21 season draws to a close for our spring calving herds and our autumn herds are now well into calving it is a good opportunity to refresh our understanding of the requirements and options for maintaining compliance with the use of registered veterinary medicines (RVMS). You will no doubt be aware that each year you participate in a RVM consult with your vet to review past RVM usage on farm and plan requirements for future use. Where you have staff members who are regularly involved in treatment case selection and product decision making it is a good idea to include them in this process – particularly if they are new to your farm for the upcoming season.

The RVM chart is a physical document which is developed through this process and it provides indications for which RVM’s should be used to treat which disease, how long treatment should occur for, dosage and how the treatment should be administered and how long cows are to be withheld from human milk supply or slaughter for human consumption. You are provided with a copy of the chart at the start of the season. However, you and your veterinarian may make changes according to disease conditions or laboratory results that become available during the season. An example could be changing the intramammary drugs that you have listed for mastitis treatment following the results of a Dairy Antibiogram. This chart will be viewed by the personnel carrying out shed inspections and it is essential that treatments are carried out according to the chart’s instructions. Additionally, from 2021 onwards you will be provided with a second chart that relates to combination therapy. For example when intramammary and injectable antibiotics are used together or where anti-inflammatory and antibiotic drugs are used together. These charts will give you guidance on the withholding periods for animals that are treated in this way and assist in meeting milk processor and shed inspection requirements.

The records you make in your dairy diary should also match the RVM chart’s instructions. Other useful places to make records of treatments against animal ID’s are the LIC MINDA (or similar herd recording app) or the electronic formats that milk processing companies provide for such records to be made.

Utilising the RVM consult process and associated resources as outlined in this article is another way Anexa can assist you to improve farm performance whilst remaining compliant with milk processor requirements. Please contact your vet if you would like further assistance.
