Herd Expansion Biosecurity Risk Guide
Source of Cattle
- From your own herd; or
- You have inspection of cattle; or
- From a single herd with known history that is practicing biosecurity and disease testing (i.e. NYSCHAP).
- From a single herd, but with no history that is not practicing biosecurity, and there is no inspection of cattle; or
- From Heifer Facility with a known history that is practicing biosecurity (i.e. NYSCHAP).
- Unknown history of assembled cattle; or
- No inspection of cattle; or
- Heifer facility with no history that is not practicing biosecurity, and there is no inspection of cattle
- Vaccinate 4-6 weeks and 2-3 weeks prior to transport;
- Known vaccination history with recent booster; and
- Booster resident herd.
- No vaccination prior to transport; or
- Improper vaccination – timing, handling and/or administration of vaccine; or
- Vaccination given too close to time of transport.
- Known test history of herd of origin; and
- Three bulk tank cultures prior to purchase and culture all new animals at freshening to identify contagious mastitis; and
- Pre-purchase BVD-PI with calf PI check; and
- Known Johne’s test history – no clinical history, a Johne’s disease farm plan in place (i.e. NYSCHAP); and
- Test negative for BLV with management practices in place; and
- Bulk tank testing for Salmonella dublin with individual blood or milk test of purchased animals or four bulk tank tests on a quarterly basis over the past year of herd of origin.
- One bulk tank culture; and
- Pre-purchase screeding on dam, but no test on calf for BVD-PI; and
- Known positive testing history of Johne’s with Johne’s farm plan in place (i.e. NYSCHAP); and
- No BLV testing, management practices in place; and
- Only one bulk tank test for Salmonella dublin.
- No known test history; and
- No bulk tank culture; and
- No pre-purchase BVD-PI testing; and
- No test history of Johne’s Disease, possible clinical history, poor hygiene in maternity pen and calf area; and
- No testing for BLV with no management practices in place; and
- No testing for Salmonella dublin.
- Use own vehicle which is clean and disinfected; or
- Use a common carrier which is clean and disinfected;
- A short transit time;
- Adequate care with longer haul.
- Use own vehicle that is not cleaned or disinfected; or
- Use common carrier that is cleaned, but not disinfected.
- Dirty common carriers; or
- Long transport with inadequate care.
Farm Animal and Post Arrival
- Complete segregation from resident herd;
- Rumen health ration with nutritionist consultation;
- Identify and plan for staff to monitor new additions and resident herd.
- Limited contact with resident herd;
- Segregations of new additions with no monitoring.
- Integration with resident herd;
- Rumen acidosis which predisposes cattle to infectious disease;
- Lack of monitoring for early signs of illness within resident and added cattle.
