SubscribeSheep and goats carry the same worms. When grazed together, goats carry heavier worm burdens than do sheep, especially in the absence of browse. Sheep and goats should only be run together, where goats have access to browse, which they prefer. If you do run both goats and sheep in higher rainfall zones, run goats on different areas of the property from sheep. Goats also share common worms with alpacas. Goats can be successfully run with horses and cattle.
NOTE: goats can also be infected by the brown stomach worm (Ostertagia ostertagi) from cattle, unlike the situation with sheep and lambs. Use adult cattle that are resistant to worms. |
Grazing management techniques that reduce the exposure of goats to worms are based on these four steps:
If these practices are not practical then consider feedlotting and ensure that feeders and waterers are designed to avoid faecal contamination.
Whether the paddock is for kidding does or for weaned kids the method of preparation is the same. However, the length of preparation will vary according to the time of the year the paddock first needs to be used typically longer in winter than in summer.
In January choose the paddocks you will use for weaning next spring/summer. From the autumn break minimise contamination with goat worm eggs by either spelling these paddocks, grazing with cattle or horses or grazing with goats or sheep for up to 3 weeks after the protection period of a drench proven effective on your property in a DrenchTest.

On winter weaner paddocks, contamination from worm eggs arises from two key periods. Most contamination occurs in late summer and autumn, however about 40% can come from worm egg deposition during late spring and early summer. Routinely giving a summer drench in November/December greatly reduces the late spring/early summer contamination.
In January the paddock(s) that will be used by weaners after the autumn break should previously only be grazed by goats* or sheep that have received an effective summer drench, or adult cattle (over 12 months old). To minimise contamination with worm eggs, graze only for 30 days after each drench is given. A similar stocking rate to continuous stocking will be achieved by stocking at 2½–3 times your normal stocking rate.
If there is excess feed, the summer drenches can be ‘staggered’ for different mobs so as to provide a longer intensive grazing period, as removing excess feed enhances the kill of worm larvae with summer heat.
Give the weaners an effective drench before they enter the ‘Smart grazed’ paddock after the autumn break: Smart grazing for weaner worm control. Note that the principles of smart grazing were developed for sheep but are likely to apply to goats.
*Where goats are referred to, include sheep and alpacas, as they can carry goat worms. While cattle also carry some goat worms, adult cattle tend to have very low burdens and contribute very little to contamination of pastures with worms affecting goats.
Graze the most susceptible kidding does (maidens, oldest does and earlier kidding does) on the least contaminated paddocks. Use WormTest results from the autumn and winter to estimate likely paddock contamination levels.
