While vaccinations are particularly topical as conversation fodder this year (will you get the Pfizer or the AZ?) they have played an important part in human and animal disease prevention for over 200 years. So let’s talk about the history of vaccines and how they work... Vaccines through history Bacteria and viruses have been the

Biosecurity: the Big Four

Farm biosecurity has three key aims: Prevent entry of disease, Contain spread if a disease does arrive on farm, and Minimize the impact of disaese if/when it occurs. When purchasing or agisting cattle, there are four key diseases that are important to be aware of: Pestivirus, Salmonella, Strep ag and Mycoplasma. Why? They all have

Winter is coming…calves and the cold

As the cold weather of winter starts to set in - it's a good time to think about how calves can be affected by cooler temperatures. All animals have what is called a “thermoneutral zone” (TNZ). As shown in the picture below, it is the temperature range where animals don't need to expend energy to maintain

Salmonella in Dairy Herds

The Salmonella bacteria is a serious cause of disease in calves and cows. It most often presents as diarrhoea - in an individual animal or as an outbreak, with many animals falling sick. There are thousands of different strains of Salmonella: typhimurium, bovismorbificans, zanzibar, anatum, dublin and newport are the most common strains we’ve cultured

Calf colostral antibodies: how to get from none to lots!

By |2021-05-02T17:13:47+10:00May 2nd, 2021|Categories: CalfWise, General Health|Tags: , , , |

Because of the structure of the bovine placenta, calves are born without any antibodies (aka "immunoglobulins" or "IgG"). Instead a calf relies on drinking colostrum, which contains antibodies that the cow has transferred from her blood stream. Once ingested, these colostral antibodies still have to be absorbed across the calf's intestines into their blood stream.

Forage crop diseases

It's a bumper year for summer forage crops such as turnips, forage rape, millet, and sorghum.  But these tasty feeds are not without their risks. Below are some diseases we can see when animals are grazing crop. Usually only a couple of animals are affected, but occasionally a large number of animals fall sick. Interestingly,

Colostrum: liquid gold?

We don't like to say that something will be a silver bullet for preventing disease, but first-milking colostrum could be considered liquid gold! Colostrum is full of antibodies and white blood cells that help newborn calves fight disease. It’s also got more fat and protein than normal milk to give calves a nutritious first feed

Eye cancer in cattle – early detection and treatment is key!
