Introduction

Animal health includes the use of measures like vaccinations, dosing and dips to safeguard farming enterprises. These precautions amount to less than 7% of the farmer’s total expenditure. To avoid essential preventative treatment and spending is to act unwisely. Animal diseases and parasites are bad news for the economy, to say nothing of human and animal health.

All animal health products should be used strictly according to label instructions. Even then, results may vary according to the disease and the stage of the disease at which treatment is applied. The earlier that treatment is administered (during the course of the disease) the better will be the results.

No vaccine can give 100% protection, but the involvement of a veterinarian plus the correct use of registered products with demonstrated effectiveness and safety could only be to the benefit of animals and producers alike.

Vaccination

Vaccination is a process where you inject a biological product into an animal. It is a process whereby one exposes an animal to a codified or weakened disease-causing organism. The more antibodies the animal has to fight that particular disease, the less likely it is to become infected. In many cases, an animal should be vaccinated yearly to ensure immunity against specific diseases.

The age at which a young animal is first vaccinated plays an important role in its response to vaccination. This is because the young animal is still getting a measure of immunisation from the mother’s early milk or colostrum. This is passive immunity, but it interferes with the vaccine if given too early.

  • Follow the correct route of application.
  • The cold chain must never be broken (transport to and storage of the vaccine on the farm).
  • Handling of vaccine is one of the major problems of vaccination failure. You have to keep your vaccines at a temperature of 4-8ºC, make sure that you have your sterile needles; you have your sterile cylinders, to avoid transmitting diseases from one animal to another.
  • The effectiveness of vaccines depends on the management of the specific farmer, so if a farmer has qualities of being a good manager and using sustained vaccination programmes those vaccines will be effective.

Parasites and resistance

Forty percent of all animal health products sold in SA are parasiticides, ectoparasiticides or dips and pour-on’s for control of ticks and other external parasites, as well as anthelmintics for control of worms. Because they are so important to SA farmers, there is much debate about parasites developing resistance to the chemicals in these products. The truth is that resistance will always be with us. It is nature’s evolutionary response towards evading suppression. To manage resistance:

  • Never introduce new (and resistant) parasites onto your property. Always ensure that introduced animals are parasite-free before being released onto the farm by first quarantining and treating them with at least two different antelmintic groups and with one or more ectoparasitic control products (dips).
  • Always follow the manufacturer’s instructions carefully when treating animals for parasites. Do not use an overstrength product.
  • For the same reasons, never use home-made pour-on products to control ticks. The amount active ingredient needed depends on the formulation used, and there is no information on home-made formulations to make these critical decisions.
  • Know the available remedies, which groups they belong to, and consult a vet, preferably from the supplier, to advise on when to change and what remedy to use next.

 

Disposal of redundant dip mixtures

Plunge dips need to be cleaned after a certain number of dip cycles. The remaining dip mixture is usually a concoction of active ingredients and their metabolites. The best practice to dispose of these dip mixtures is:

  1. Pump it into drums and have it disposed of by certified hazardous waste management service providers. Some of these are EnviroServ, www.enviroserv.co.za; A-Thermal, https://athermal.co.za ; and Rapid Spill Response, https://rapidspillresponse.com.
  2. Dip mixtures can also be pumped into a plastic lined evaporation pond that is fenced off and cover with netting to keep any animals out. Once the liquid has evaporated the sludge must be collected in plastic drums and disposed of by certified hazardous waste management service providers as mentioned above.

Do not attempt to dispose of any redundant dip mixture or dip residues by pumping it into natural water bodies or onto the soil. The results will be disastrous for the environment.

To improve delivery of veterinarian services, Department of Agriculture, Land Reform and Rural Development (DALRRD) has introduced measures like expanding the existing bursary scheme for veterinary studies and introducing a year’s compulsory community service (CCS) for vets after graduating.

Find Directorate documents, contact details and other information at www.dalrrd.gov.za. Of relevance to this chapter are (i) Animal Health (ii) Veterinary Public Health, and (iii) Agriculture Inputs Control.

State Veterinary Services sponsor the testing for certain animal diseases. Please contact your nearest State veterinarian office or Provincial office for advice (find extensive details of chief director, state vets, laboratory services per province on the website). See also:

University of the Free State Department of Zoology & Entomology – www.ufs.ac.za A variety of factors can build ticks’ resistance to chemical treatments: the nature of the substance, the number of applications, the method of application, and the spreading of ticks through animal movement. Farmers who have problems dealing with ticks can send samples to the Pesticide Resistance Testing Facility (PRTF) at the University of the Free State to be tested for resistances.

Training and research

  • If you are a farmer, consider undergoing some form of Primary Animal Health Care (PAHC) training. It will certainly benefit your farming operation.
  • ARC-Onderstepoort Veterinary Research (ARC-OVR) www.arc.agric.za OVR is part of the Livestock and Animal Health Division. Research activities at the OVR focus on the development of vaccines and diagnostic methodologies, applying the latest molecular biological techniques to prevent and control economically important diseases. The Institute promotes animal health and welfare by providing effective and diagnostic service, and vaccines against Foot-and-mouth and tick-borne diseases. The OVR is a collaborating centre for both the OIE (surveillance and control of animal diseases in Africa) and FAO (emergency preparedness for transboundary animal diseases for Africa, Helminth anthelmintic resistance and biological control for Africa, and the FAO Reference Laboratory for Arthropod transmitted viral diseases for Eastern and Southern Africa which includes seven reference laboratories for economically important viral diseases). Short training courses at ARC-OVR include tick identification and zoonotic disease.
  • Companies involved support and do research on various aspects of animal health, both individually, at their own research facilities, and also collectively on aspects of importance to the farming community such as: tick resistance to ectoparasiticides worm resistance to endoparsiticides microbial resistance to antibiotics environmental issues such as dung beetle-and oxpecker compatible remedies.
