Spring pastures

Spring Pastures: What to consider before letting your animals out to pasture With lambing season upon us, there are many things to consider when grazing animals. Many cattle herds and sheep flocks are housed indoors over the winter months for various reasons. I’m sure they wouldn’t be too fond of the recent snow flurries that we’ve had! Indoor housing during the winter months provides protection from the elements and cold conditions, as well as conservation of energy that would have…

Paratuberculosis (Johne’s disease) in Cattle What is Johne’s disease? Johne’s disease is an infectious disease in cattle and other ruminants which is caused by Mycobacterium avium subspecies paratuberculosis, commonly known as MAP. It is closely related to the organism that causes tuberculosis and can survive on pasture for many months. The infection is contagious within the herd and young animals are more susceptible to the disease than adults. This disease damages the intestines and results in persistent diarrhoea, weight loss…

Anthelmintics: when should I use a wormer?

Anthelmintics: when should I use a wormer? What are Anthelmintics? Anthelmintics or wormers are widely used across the globe, and a lot of the time can be misused causing resistance issues. Anthelmintics are drugs used to treat infection with nematodes (roundworms like Ascaradia galli in chickens), cestodes (tapeworms like Moniezia expansa in sheep) and trematodes (flukes like Calicophoron daubneyi in livestock). How do I know which wormer to use? Firstly, how do you know your animals need to be wormed? Have you noticed symptoms or seen…

Quality monitoring of Liver fluke metacercariae

Quality monitoring of Liver fluke metacercariae At our laboratory part of the work we do is to maintain several colonies of snails, these are the intermediate host in the life cycle of the liver fluke Fasciola hepatica. The metacercariae we produce are supplied to Universities and Pharmaceutical Companies and used in research to gain a better understanding of the parasite, its control and the growing problem of its resistance to anthelmintic treatments. To ensure the metacercariae we supply to our customers…

Risk of lungworm in unvaccinated calves and cattle

Risk of lungworm in unvaccinated calves and cattle What is Lungworm? Lungworm is a nematode that can affect many species of animals including sheep, cattle, deer, goats and horses. Each species typically has associated species of lungworm that it is susceptible to. The bovine lungworm called (Dictyocaulus viviparus) is the most common cause of lungworm in cattle. Depending on species, lungworms reside in the bronchi and bronchioles of the lungs (and sometimes heart) where they lay eggs. These eggs are…

UK Parasite Watch July Edition: Parasitic Gastroenteritis (PGE)

UK Parasite Watch July Edition: Parasitic Gastroenteritis (PGE) What is PGE? Sheep Parasitic Gastroenteritis or PGE is one of the biggest challenges to the welfare and economic value of keeping sheep, being the most commonly diagnosed cause of mortality in young lambs in England and Wales. As the infective period progresses eggs will be shed onto pastures by infected animals. High pasture burdens may lead to disease and reduction in welfare and profit. What causes PGE? The causative agents of…

The shifting nature of veterinary pharmaceutical R&D delivery…a new niche opportunity

The shifting nature of veterinary pharmaceutical R&D delivery…a new niche opportunity Increasingly, large pharmaceutical companies are evolving their business strategies and are incorporating outsourcing of R&D as a norm. Traditionally, large pharma companies would operate in house R&D activities. Nowadays, a multifaceted approach exists for delivering new technologies incorporating in house R&D activities; use of contract research organisations (CROs); and utilising venture capital funded start-up companies. Why are veterinary pharmaceutical companies moving to favour outsourcing of R&D? Companies are moving…
