SubscribeManaging and spelling pastures at the right times and for the necessary length of time is a proven method to reduce the level of contamination on paddocks.
However, moving goats between pastures each few weeks will do little to reduce the worm-risk, especially in high-risk barber’s pole worm areas.
Grazing management methods are not presented here because few smallholders are in a position to apply these options effectively, however the link is included below for refernce.
More information on grazing management to avoid worms can be found:
Providing a large proportion of the goat’s diet as browse or taller crops, shrubs or trees (where edible parts are above 20 cm height) greatly reduces intake of worm larvae, as the larvae rarely ascend more than 15 cm above the ground.
If this is grazed by the stock, be aware that as it becomes eaten out and the animals start to eat close to the ground or need to eat more low-growing pasture, then they will pick up more worm larvae.
Browse can also be cut and provided in racks for the animals to feed on. The page pasture and browse for worm control in goats has more information.
Feedlotting is a highly effective means of avoiding worms. Goats are separated from pasture that contains the infective stage of worms.
Many goats in small herds or kept in backyards already receive a lot of supplementary feed. When worm control costs are taken into account, going to a zero grazing (feedlot) situation may be cost effective, especially if existing pastures can be converted to growing browse for cutting and feeding.
In situations where paddocks are heavily contaminated with worms on an ongoing basis (and in some cases, drenches are no longer very effective), feedlotting becomes the only viable option to prevent illness and death from worms.
Feedlotting can also reduce the spread of Johne’s disease, which occurs in some dairy goat herds.
It can also protect against dog attacks and paralysis ticks, which are also common problems in goats kept in peri-urban areas.
