DISEASE |
MEASURABLE IMPACT (observed syndrome) |
SOLUTION |
Clostridial Disease |
Losses from weaning to turn of primarily. Breeder mortality. |
Vaccinate calves and cows with Ultravac® 5-in-1 or Ultravac® 7-in-1. |
Botulism |
Losses from weaning to turn off primarily. Breeder mortality. |
Vaccinate weaners with Longrange®. Vaccinate all stock annually thereafter with Ultravac® Botulinum or Longrange®. |
Vibriosis |
Low pregnancy rate in heifers (if control mated). Losses from pregnancy testing to branding. Too many late calves. |
Vaccinate heifers with Vibrovax® prior to mating (if bull control is poor). Vaccinate bulls with Vibrovax® annually. Cull heifers and cows that do not calve in 12-month cycle. |
Trichomoniasis |
Low pregnancy rate in heifers and cows. Losses from pregnancy testing to branding. Too many late calves. |
Cull micky bulls and old unmusterable bulls. Test bulls prior to mating and cull infected bulls. Cull heifers and cows that do not calve in 12-month cycle. |
Pestivirus (BVDV) |
Low pregnancy rate (in control mated heifers). Too many late calves (second calvers and cows). Losses from pregnancy testing to calving. Losses from weaning to turn off and cattle that fail to grow well. Increased scours/coccidiosis and pneumonia in calves, weaners and growing cattle. |
Determine herd status using tests for antibodies. Vaccinate heifers prior to mating with Pestigard®. |
Leptospirosis |
Losses from pregnancy testing to calving. Leptospirosis in workers. |
Vaccinate calves with Ultravac® 7-in-1 or Leptoshield®. Vaccinate cows with Ultravac® 7-in-1 or Leptoshield®. |
3-day Sickness (Bovine Ephemeral Fever) |
Clinical disease and losses in young, growing cattle, replacement heifers and introduced bulls. Low pregnancy rate (if bulls affected). Losses from pregnancy testing to branding in heifer’s calves (if heifers affected). |
Vaccinate bulls with BEF vaccine. Young cattle and introduced bulls are at most risk in Northern Australia. |
Vitamin A Deficiency |
Losses from pregnancy testing to branding. |
Inject cows with good quality Vitamin A preparation at pregnancy testing in years following low wet season rainfall where green feed/schrubs have been unavailable. |
Tick Fever |
Losses from weaning to turnoff. Losses in introduced cows and bulls. |
Vaccinate bulls and weaners with Tick Fever vaccine. Consider vaccinating introduced stock, especially if lower Bos Indicus. |
Coccidiosis |
Scouring, often with persistent straining and blood tinged faeces and occasional nervous signs (receumbency and padding seizures). |
Add an ionophere (e.g. Bovatec) to supplements. |
Dehorning Losses |
Breed polled cattle |
Select true polled bulls using HornPoll generic test. |
