For suckler cow units, the first hurdle in the back end of the year is weaning the calves with as little weaning check as possible. Calves which become very stressed at weaning can experience a growth check, which not only has a negative impact on meat quality as gristle will be laid down, but they could see a setback worth 10-20kg liveweight.

There are several ways to reduce weaning stress, including:

Vaccinate before weaning

When you wean calves in a stressful environment, they tend not to eat as much as they should for a few days. If they don’t eat, they don’t take in enough energy and protein which are both needed to let the immune system fight any challenge.

Getting calves vaccinated for respiratory diseases before housing and before weaning is a great way to reduce the number of sick and poor performing animals post-weaning. The protocol for vaccinating should always be talked through with the farm vet and be specific to your farm and risk factors. Consider this year if you could do your vaccinations earlier than usual, to give your calves a head start.

Don’t abrupt wean

Taking all animals inside and separating the cows from the calves straight away is not advised as this places more stress on the calf, increasing likelihood of a knock to performance. Other options include two stage weaning, where a nose ring is fitted to prevent calves from suckling their mothers, meaning milk is removed, but they still have the company of their dam. Physical separation then happens after 4-7 days. Alternatively, fence-line weaning can be a good option. This is where cows and calves are on opposite sides of a fence. They can still hear, see and smell each other, reducing the amount of pacing, calling and stress.

Limit mixing groups

It’s inevitable that groups of calves will have to be mixed at housing. But limiting the number of times this happens will help calves settle quicker. Harbro trial work showed that mixing groups of cattle together disturbed their hierarchy so much, it took them around 12 days to get back to gaining the same weight each day as before the mixing.

Creep feed

To minimise weaning stress, consider feeding creep for 3-4 weeks before weaning. By 200 days old, calves will be taking the majority of their feed from grazing and creep, rather than milk. At this stage, feeding the calf directly is more efficient than feeding the cow to produce milk.

Not only does creep feed reduce the stress at weaning by providing a consistent feed source and familiarity to the calves, it can also be packed full of goodies to help support the immune system, helping reduce the risk of respiratory issues.

New for this season, the Grampian Menthol Beef powdered mineral is packed full of antioxidants to help support the immune system, as well as menthol which helps keep airways clear and open. This mineral can be incorporated into a total mixed ration (TMR), home-mixed blends or top-dressed onto silage.

What is an antioxidant and what do they do?

Antioxidants circulate the body, to reduce oxidation which causes damage to cells. Antioxidants help maintain integrity of body cells, to keep animals fit, healthy and ready to perform.

• Oxidation is the process which turns a cut apple brown.
• We’re told to eat 5 fruit & veg a day to fill us full of antioxidants from a range of sources, to optimise absorption and reduce our risk of disease
