When should ewes be vaccinated?
The annual booster for ewes should be given 2 to 6 weeks pre-lambing. This not only protects the ewe during lambing, it also provides immunity to her lamb from antibodies in the ewe’s colostrum. This lasts 6 to 8 weeks, usually tapering off to coincide with the lamb’s first vaccination at marking.
What happens if you don’t vaccinate sheep?
Without an annual booster dose the animal will be at risk of disease as the antibody levels will fall below the protective level. This is the level of immunity required by the animal to provide protection against infection or disease.
How often should sheep be wormed?
once a year
Ewes should only be wormed once a year at lambing time; this will reduce the number of eggs on the pasture so that there are less for lambs to pick up. Lambs have little resistance to worms in their first grazing season but this develops with time.

A typical sign of a worm problem is unthrifty sheep. An unthrifty sheep is one that is not eating properly, is losing condition, tends to lag behind the mob when moved and, in severe cases, is clearly weak. A worm problem often (but not always) results in sheep scouring and becoming daggy.

How often do sheep need to be wormed?
every three to four weeks
Normally sheep should be treated every three to four weeks. Keep in mind that worms may develop resistance to a drug if exposed frequently. Lower stocking rates will reduce the intensity of the deworming program. Fewer sheep result in fewer shed worm eggs within a given area, and thereby reducing parasite loads.
