Winter is coming…calves and the cold

By |2021-05-20T07:52:16+10:00May 19th, 2021|Categories: CalfWise|Tags: , , , , |

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!

Summer is not just the time for pinkeye , it’s also the time we see more cancer eye in cattle. These are fast-growing cancers of the eyeball or eyelids. Early detection and treatment of eye cancers a) makes the treatment itself simpler, and b) minimises the risk of the cancer spreading (both locally around the

Know the enemy: Mycoplasma!

By |2020-12-15T20:54:41+11:00December 15th, 2020|Categories: CalfWise, HerdWise, MilkWise|Tags: , , , |

Mycoplasma is a bacterial infection of cows and calves. There are several strains that can cause disease but Mycoplasma bovis is the most common. We have seen more Mycoplasma in the district over the last couple of years, and it is a disease that everyone should be aware of. We see Mycoplasma disease present in

Lungworm alert

By |2020-11-02T15:24:17+11:00November 2nd, 2020|Categories: CalfWise, Farm Services, HeiferWise, HerdWise|Tags: , , , |

We have seen a number of cases of lungworm in young heifers in the district, so thought it would be good to revisit how this nasty parasite works. Lungworm, caused by the round worm Dictyocaulus viviparus, usually occurs in heifers less than 10 months of age. In particular, those heifers with no immunity that are

Fractured legs in heifers? Think copper deficiency!

In the last 12 months we have had a number of farms where maiden heifers - at the point of calving or in the weeks soon after calving - spontaneously fracture the humerus in a front leg. This is distressing for everyone as there is nothing that can be done and the heifers need to

Monday the 3rd of August 2020 In addition to the Level 3 restrictions that were announced for Regional Victoria yesterday, from today (almost) everyone aged 12 and above must wear a face covering when they leave home. When we talk, breath, cough, sneeze, or laugh, the large, wet, heavy respiratory droplets fall relatively quickly. If
