Herd Health


Fat tail sheep vasectomy:

This Fat Tail Sheep of The Animal Ambulance came in for a vasectomy - done here by Dr Nicholl Jacobs.  Vasectomys are preformed in production animals where only the spermatic cords are bound and cut to prevent reproducing. 

We place the sheep in a upright position to limit the amount of respiratory stress during surgery.

 This is a minimal invasive procedure done through a tiny hole and is only done under sedation and local anaesthesia.  Animals usually fully recovered within an hour or two.

Sheep skin


Let us take a closer look at those animals that provide us products to keep us warm this upcoming winter.


Sheep are not often affected by skin/fleece problems especially not during the cold winter months. But even the smallest farmer can tell you that when sheep start losing wool, they start losing hair.


All skin conditions in sheep are controlled diseases. That means that if a veterinarian diagnose an infectious (bacterial, viral or mite) cause for the skin condition the local state vet must be notified.


Sheep are sensitive creatures and that is why they play host to a vast array of organisms that want to infect them. These range from the dreaded Sheep scab mite (Psoroptescommunisovis) and Sarcoptic mange mite (Sarcoptesscabiei) to the more commonly found Itch mite (Psorergatesovis), Lice (Damaliniaand Linognathus) and keds (Melophagusovinus). Bacterial infections i.e. fleece rot, sprouting from prolonged wet seasons are often accompanied by flies and could cause a lot of harm.


When sheep are itchy they spend more energy on scratching then what they do eating or reproducing, indirectly affecting the farmers’ production margins. Farmers can incorporate preventative measures like dips (Taktic) during periods of high infestation. However, it is very important to get a veterinarian to inspect your sheep early so that preventative measures like long acting ivermectin injections etc. can be given, rather to wait and have your flock potentially thinned out.


There is a lot to talk about production animals and herd/flock management. If any queries should arise please feel free to contact us for advice and further information.
