Room 3 - Sheep, Camelid and Goat

Session Program

Due to their evolution, goats metabolize veterinary medicines more efficiently than sheep.  This means that they must be given at higher doses or more frequently, than the sheep label instructions i.e. “off-label”.  Hence a veterinary prescription or Veterinary Advice Note must be written when treating goats.  There are resources that can help especially for worm drenches, but sometimes research data is lacking.  Veterinarians must then use their professional judgement to balance the goat’s metabolic efficiency for clearing veterinary medicines, with the increased dose rate or interval, against the need to have meat with-holding periods below the level of reporting for chemicals not found in products registered for goats.  Treating goats that are producing milk for human consumption is especially difficult, as many veterinary medicines have “DO NOT USE in sheep producing milk for human consumption” statements on their label.  A veterinary prescription cannot override a DO NOT USE statement.  Residues have been detected in export goat meat as part of the National Residue Survey, so setting adequate with-holding periods in prescriptions is essential. 

Internal parasites remain the most costly disease to the sheep industry of Australia and thus to serve your sheep clients well, requires a good understanding of this issue.

Integral to parasite management is the worm egg count (WEC) which enables us to get a picture of the parasite burden in the animal and to what contamination is being put onto the pasture. All non-strategic drenches should be preceded by a WEC. A drench resistance test is the most valuable way we have of determining what drenches we should be using.

Looking at the whole farm approach requires us to follow the principles of integrated parasite management (IPM). This requires us not only to look at what drench to use and when, but also to consider the whole farm, the management of the animals and pastures including the seasons and genetics.

This presentation will examine

1.       Drenches what works for that farm and how to choose which to use.
2.       The timing of drenches, 
3.       The importance of grazing management, 
4.       The role of nutrition, 
5.       Flock and weaner management
6.       Genetics selecting for resistance and/or resilience in the flock. 
7.       Monitoring and testing
8.       Other potential tools

Parasite control does not happen in isolation, so all decisions have to be made along with a good understanding of their effects on the whole farm management. 

Dermatological conditions are common in alpacas in Australia. Alpacas typically present with combinations of the following: pruritus and self-trauma, erythema, alopecia, pustules, papules, hyperkeratosis, and/or lichenification of the face and ears, ventrum, feet and inguinal and axillary areas. Diagnotic tools include skin scrapings, skin smears, skin biopsies and culture and sensitivity. Causes of skin disease include ectoparasites (e.g. sarcoptic and chorioptic mange, lice), bacterial (e.g. Staphlococcus intermedius, Dermatophilus congolensis, Corynebacterium pseudotuberculosis, Mycobacterium ulcerans, Burkholderia pseudomallei), viral (e.g. parapox) and fungal (e.g. Trichophyton spp.) infections, neoplasia, insect worry and atopy. Treatment options include miticides, insecticides, antibiotics, antihistamines, shampoos, immunotherapy and/or oclacitinib. Zinc-reponsive dermatosis is a questionable condition. Corticosteroids should not be administered to pregnant camelids by any route. Note that no drugs are registered for use in camelids in Australia.
