Parasites & Vaccinations


Improving Livestock Performance

The benefits of focusing on keeping livestock healthy by actively following a preventative health care programme far outweigh the costs. Parasite Control and a Vaccination programme reduces the incidence of disease that can lead to reduced fertility, slow growth, loss and ultimately increased costs and reduced profitability.


Internal and external parasites can cause poor performance of livestock and can lead to economic loss for the owner. We can advise on the most appropriate parasite control measures for your herd or flock and create a farm specific treatment strategy. For forecasted parasite threats for the local area visit the National Animal Disease Information Service.

In general the main threats are from:

 Nemotodes and Lungworm

With all animal diseases prevention is better than cure and more economic as it reduces the risk of loss and cost of treatment to infected herds and flocks. An effective veterinary herd health plan is essential to maintain health and to prevent costly diseases.

Bovine Virus Diarrhoea (BVD)

It's a legal requirement that all cattle screened for BVD.  BVD is one of the most important diseases of cattle in terms of economic cost and welfare, causing abortion, infertility, failure to thrive and often death. Around 40% of herds in Scotland show signs of exposure. (Scottish Government)

The Scottish Government has committed to supporting an ambitious industry-led scheme to eradicating BVD from Scotland with the BVD Eradication Scheme.


Mandatory Annual Screening

All keepers of breeding cattle herds will be required to screen their herds for BVD by 1 February 2013, and annually thereafter. A range of testing methods is available. Also, where there are calves born in non-breeding herds, they must be tested within 40 days. More information on Mandatory Annual Screening

The Scottish Government quotes the annual benefits after eradication of BVD in your herd are likely to be:

Dairy £15,800
LFA specialist beef £2,400
LFA cattle and sheep £1,800
Lowland cattle and sheep £2,400

(LFA=Less Favoured Areas)

Major financial losses result where infection is introduced into a group of susceptible breeding cattle resulting in poor reproductive performance and the birth of calves with persistent virus infection. While elimination of infection from the herd is optimal, vaccination is highly effective and produces a substantial cost benefits

Leptospirosis is a common infection in dairy and beef herds. Economic losses result from:

  • Infertility
  • Abortion
  • Poor milk yield

Strategic antibiotic treatment combined with vaccination is the preferred course to reduce the risk of infection in cattle herds. An initial course of two injections is required four weeks apart followed by annual boosters. Vaccination should prevent urine shedding following exposure and will protect against milk drop and abortion.

Neonatal scour

Effective vaccines are available against the most important infectious causes of calf diarrhoea but such a prevention strategy will only work if calves receive adequate volumes of good quality colostrum within 12 hours of birth, and in the case of viral causes, continue to receive stored colostrum from vaccinated cows for the first two weeks of life.

Enzootic Abortion of Ewes - Toxoplasma gondii and Campylobacter

Purchase accredited stock and vaccinate them against EAE and Toxoplasmosis 70 per cent of abortion outbreaks in the UK are caused by Toxoplasma gondii and Campylobacter. Vaccination provides excellent immunity and as it provides lifelong immunity it is extremely cost effective. It should be administered at least 3 weeks before the breeding season.


Many infectious causes of abortion can also infect humans (zoonotic infection) An abortion rate in excess of two per cent is suggestive of an infectious cause and veterinary investigation is essential.
