Toxicities that cause disease and death of calves are luckily few and far between. When they do occur – sometimes from a simple mistake - it is extremely upsetting for those involved. But if we can use the bad as a timely reminder, we can help ensure it doesn't happen to anyone else. Recently
When a calf is born, it's stomach (the abomasum) is 2–4 litres in size. It secretes enzymes that digest milk, providing the calf with energy and protein for growth. However, over time, we need to turn a calf's stomach into a cow’s stomach: a 150–200 litre rumen where microbial enzymes do the digestion to provide
Bacteria are amazing little critters. They can do so much good, such as fermenting the feedstuffs in cows’ rumens to provide them with the nutrients to live, grow and produce milk. They can also do so much bad, for example E. coli and Salmonella can cause severe diarrhoea and sometimes death in calves.
While we all spend time with family these holidays, we thought we’d talk about our LEAST favourite family – Salmonella. This bacteria is a serious cause of diarrhoea in calves and cows (and lots of other animals for that matter – including us!) How does Salmonella show up? Clinically affected animals present with diarrhoea, depression,
At our recent CalfWise workshop, the topic of colostrum antibodies came up: what they are and why they are important. As it’s time to start planning colostral vaccinations we thought it would be worth revisiting.
What is pinkeye? Pinkeye is the common name for a corneal ulcer in cattle. The main cause of pinkeye is the bacteria Moraxella bovis, which is present in nasal and eye secretions of clinically infected and carrier animals. It can spread between animals via flies or through close contact. Pinkeye typically occurs in young stock
The Vet Group's CalfWise Workshops present the latest, topical information on calf rearing, relevant to our district. Our CalfWise team focuses on practical advice to help you achieve healthier calves. The workshop is run over two days and participants come away with: A thorough understanding of the biology of calf immunity and infection Key points
Disbudding is an important procedure for the wellbeing, health and productivity of your valuable calves. The Vet Group’s disbudding service aims to provide a professional and consistent package that includes sedation, long-acting anti-inflammatory pain relief and local anaesthesia prior to hot iron cautery. Our disbudding team also checks for hernias, removes extra teats and treats
We have recently diagnosed lungworm in a number of youngstock in the district and thought it would be good time to write about this disease. Lungworm, caused by the round worm Dictyocaulus viviparus, can present as coughing, loss of body condition, increased respiratory rate and in worst case death. Outbreaks generally occur in heifers less
Coccidiosis By Dr Zoe Vogels Coccidiosis is a protozoal infection of calves and heifers that can cause diarrhoea (scouring) and poor weight gain. As seen in the diagram below, calves become infected by ingestion of the "egg" or oocyst of coccidia from the pasture. Once infected, the parasite multiplies in the intestine of the calf
