Lambs in many mid-season vaccinated flocks are reaching a stage where naturally derived immunity is wearing off (protection lasts from six to 12 weeks). There are numerous products on the market and a choice should be made on which vaccine best suits your flock with products varying in the range of cover they provide for clostridia and pasteurella. A full course of two shots administered four to six weeks apart is recommended to provide lambs with maximum protection.
Protective equipment
Most flocks will be implementing some form of blowfly protection from using pour-ons to dipping.
Safety precautions should come to the fore. A good face mask and filters will cost from €30 to €50 and is good value. Where masks are already present remember to check the appropriate filters are in place and still in date. It is also worth investing in gloves, goggles and protective clothing.
How much are you paying to treat and prevent blowfly strike?
