Pink eye pain... Pink eye - or corneal ulceration - causes farmers and stock a lot of grief! While it usually occurs in young stock from November through to March, it's increasingly being seen over the winter months too. Pink eye is mainly caused by the bacteria Moraxella bovis and Moraxella bovoculi, both of which

Lungworm, caused by the round worm Dictyocaulus viviparus, generally occurs in heifers less than 10 months of age. In particular, those heifers with no immunity that are exposed to high numbers of worm larvae when put onto pasture (such as a group of Spring-born calves weaned onto pasture grazed by Autumn calves). Lungworm disease can

Last week was #InternationalMicroorganismDay, so we thought we'd shine the light on some of the microbes that can be the most frustrating: those that cause calf scours! The microbes that cause calf scours (aka calf diarrhoea) can be viruses, bacteria and/or protozoa that damage the lining of the gut. This means that the milk and

Caution: avoiding abamectin toxicity in calves!

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

Calf rumen development – the key ingredients!

By |2019-09-06T12:18:19+11:00July 24th, 2019|Categories: CalfWise|Tags: , , , , |

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

Microbe maths!

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.

Salmonella vaccination – keep it in the family!

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
