MANAGEMENT OF M.BOVIS AT CRV:
CRV Ambreed has a strong strategic focus on biosecurity, built up over many years, and as the second largest producer of AI semen in New Zealand we are confident our biosecurity protocols and procedures will effectively mitigate the known risks associated with the current M.Bovis outbreak.
In order to ensure our bulls and staff visiting farms maintain appropriate biosecurity standards, we have highlighted below key components that relate to the management of M.Bovis at CRV Ambreed.
International disease testing standards are followed:
1. CRV follows the international disease testing standards set by the O.I.E (World Animal Health Organisation) for animals entering an export approved location.
2. All CRV imported semen meets the import health standards and requirements set by the Ministry of Primary Industries (MPI).
3. All CRV semen is frozen and treated with antibiotics as recommended internationally for controlling M.Bovis.
CRV facility management:
1. CRV’s facilities are under the direct supervision of two veterinarians trained in the management of biosecurity standards and animal health.
2. CRV’s facilities operate under isolation quarantine zones that include double fenced boundaries with a 5 metre separation from any neighbouring property.
3. All animals being brought onto a CRV facility go through strict quarantine protocols which include extensive disease testing.
4. Facilities are audited on a Bi-Annual basis by MPI against EU Directives and NZ Legislation and Codes of Practice.
On farm biosecurity:
1. CRV has undertaken to formulate on farm biosecurity practices to ensure the risk of disease transfer from farm to farm is appropriately managed and includes hygiene practices such as disinfection and clothing/equipment removal for tasks such as herd testing and insemination.
2. CRV staff have been trained and supplied with the necessary equipment to treat every farm in the same manner with regard to cleanliness and hygiene practices.
3. We will ask if there are any known infectious diseases on the property that we need to be aware of, prior to arriving on your farm.
4. CRV will continue to work with MPI and adopt manage any necessary changes with regards to on farm biosecurity.
All bulls located at the CRV Bellevue production and logistics facility have been tested for Mycoplasma Bovis with a ‘not detected’ result.
This includes our 2018 progeny test team bull intake which have arrived on the location since January 2018
For each 2018 progeny test bull we required a signed farmer and veterinary declaration outlining the bull is not originating from a location that has been under any MPI Notice or Restriction for M.Bovis.
We have used a preputial swab on all bulls and in addition a deep naso-phyangeal swab on any bulls coming from outside CRV. These samples have been submitted for a PCR test.
We will be working with all appropriate industry personnel including MPI to determine if there are going to be any proposed changes to the requirements of operating an MPI approved semen collection centre.
All testing we have completed to date has been 100% voluntary and we will if necessary maintain that philosophy
With the current tests available it is not possible to guarantee that bulls/semen do not contain M.Bovis bacteria.
Whilst the test cannot be relied upon 100%, testing in conjunction with our biosecurity and processing protocols, ensures we are effectively mitigate the known risks of exposure to M. Bovis
MPI is in the lead providing direction to any regulatory requirements which CRV will comply with.
CRV are part of an MPI approved Semen Reference group (representing AB companies)
Semen has been identified as being a possible low risk pathway of the introduction of the disease into NZ
CRV adheres to the current import legislation whereby antibiotics are added to the semen. In addition, we are working with all imported suppliers to test, at source, the bulls used to supply semen to New Zealand.
The Technical Advisory Group of MPI have published the outcomes of their findings which is available on the MPI website – https://www.mpi.govt.nz
We are undertaking PCR testing of semen from newly imported bulls.
MPI have advised that spread of the disease from farm to farm has only been through the movement of cattle so far, and spread between cows in close contact.
This is the main reason why AI remains a low-risk option for cattle breeding in comparison to natural mating bulls
Yes – however any farm under any form of MPI notification (NOD/RPN) /restriction must receive approval from their case manager before engaging with the delivery of all CRV Ambreed services.
It is the responsibility of the farmer to inform CRV if they are under any Official notice from MPI – MPI can not share any farmer information with the general public because of the Privacy Act in place in NZ.
AI is a very important tool for preventing the spread of disease on farm, it is much safer than using service bulls, so to get the majority of cows mated to AI will help reduce the risk of spreading the disease.
AI Technicians will have additional hygiene processes to follow to ensure they arrive and leave every farm completely clean.
It is important to follow industry updates and CRV will not speculate on individual positions being taken by commercial entities or individual personnel.
We recommend farmers refer to MPI, DairyNZ and Federated Farmers for official updates on the current disease outbreak.
