Something that is often over looked. We dose our sheep with a vitamin supplement called All Vit T during lambing time, pre-tupping and in the winter depending on weather/condition of grazing/sheep. We also does all lambs and sheep before they leave us for new homes. And we have mineralised salt block licks especially for sheep available in the barn. Not all grass/ground contains all the vitamins/minerals required by sheep, especially in persistent wet weather when they are washed from the ground. If sheep are kept on a very small area they probably won’t be able to get everything they need. If your sheep are not breeding then they have much more chance of getting enough of these things to sustain them. If needed you can buy specific vitamin/mineral mollassed feed buckets or salt based blocks specifically for sheep. But be careful with the feed buckets as sheep tend to gouge out, rather than lick, the hard mollassy mineral buckets and damage their teeth, the salt based licks are much better. It is very important that you don’t give them anything intended just for horses or goats or anything else that contains higher amounts of copper which is toxic to sheep in a high enough dose.
