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
The Vet Group's CalfWise Workshops present the latest, topical information on calf rearing, relevant to our district.

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
With the new season’s calves starting to make an appearance we thought it would be timely to revisit the physiology of the calving process and the common reasons why interventions may be required. As with any medical emergency, the success of calving first aid is highly dependent on the prompt and effective action. There are
A dairy cow’s stomach is made up of four parts and relies heavily on fermentation for the digestive process (rumination). The four stomach parts are reticulum, rumen, omasum and abomasum (see figure 3 below). The reticulum and the rumen is where fermentation occur, the omasum absorbs water and minerals from the rumen, and the abomasum
Zoe Vogels What happens when something stresses a calf? At a physiological level, it sets off a chain of chemical reactions in response to the stressful event. The calf’s brain tells the adrenal glands to make the hormone cortisol. Cortisol increases the blood pressure, makes the heart beat more strongly, diverts blood to the
Dr Tom Walsh Calving has become a year round activity in our region which means it is more important than ever to make it a routine process rather than a stressful one. Having a good transition plan will go a long way to ensuring that the calving period will fit in with the work flow
Calves are born with no natural protection from disease and it can take 3 to 4 weeks for them to develop their own antibodies. One of the best ways to protect your calves during this time, is to give them colostrum ─ the first milk produced by the cow or heifer after she has calved.
