The cattle wormer market has seen many significant changes over
the years, but many farmers still prefer a Bolus to a Pour-On. Before
stock receive their spring turnout treatment, it is worth considering
additional lungworm protection. By stimulating immunity with a vaccine,
a more profitable control programme can be achieved, particularly
for those dairy replacements or where there is a known lungworm
problem on-farm.
Intervet’s lungworm vaccine, Bovilis Huskvac, used pre turnout,
combined with the use of a bolus, such as the company’s Panacur
Bolus, should provide season-long control of the important species
of gutworm and season-long immunity from lungworm, maximising your
profit.
After the initial course of Huskvac, as with most vaccines, a ‘booster’
is required to stimulate the immune system and help provide immunity.
In the case of husk, the same effect as a booster is provided by
allowing the animals to be exposed to lungworm while out grazing.
To achieve this natural exposure, it is important that the chosen
wormer, (Pour-On or Bolus), doesn’t kill lungworm ingested
by the animal. If the chosen wormer kills 100% of the lungworm larvae,
then there is a chance that immunity won’t be maintained and
a heavy challenge later in the year, or next season will result
in an outbreak of husk – even in adult cattle. Advice on the
use of Huskvac and wormers should be sought from the surgery.
