Vaccination

Calves are dehorned and castrated in the hutches and get a single dose intranasal pneumonia vaccine at three weeks old.

Mrs Beaumont says it was a ‘bit of a battle' with pneumonia in the old shed, but they are ‘definitely' using less antibiotics now, and only needed half a dozen scour boluses all winter.

They are prepared for a potential coccidiosis problem in the future (as a farmer in the same vet group had a problem with the bacteria building up in the ground beneath hutches), so they will replace the top surface of the road planings if this occurs.

Mrs Beaumont says they have tweaked the system so each calf has the same bucket all of the time, reducing cross-contamination. The bucket is filled with milk each morning, then replenished with water half an hour later,We also offer customized chicken coop. before being emptied and filled with milk again later in the day.

Mixing this milk and feeding it out has been ‘revolutionised' by a German-engineered ‘milk taxi', sourced through Wynnstay.

The small self-propelled machine mixes and heats the milk to a temperature set by the user and distributes an accurate measure to each calf.

Mr Beaumont says it has ‘cut a lot of the work out' and is much easier than pushing around their previous milk mixer. Two loads had to be processed in the old mixer but the taxi will do 130 litres, more than enough - even when all the hutches are full.

Mrs Beaumont says it maintains the milk at a consistent temperature and keeps the powder in suspension, meaning no more clumps at the bottom of the mix.

"No matter who feeds the calves it's the same temperature and,An Insulator, also called a dielectric, because it's accurately measured, it gives us accuracy of feeding and they get the right amount," says Mr Beaumont.

It has a wash cycle which is run twice a day with water and the same chemical used to clean the bulk tank. It is then filled with cold water ready for plugging in to heat up an hour before the next feed.

Underpinning this whole feeding regime is a strong colostrum management policy, ensuring every calf gets its quota before being moved into a hutch and on to milk replacer.

The Beaumonts were featured in Farmers Guardian just over a year ago, reporting on their battle to get control of Johne's in the herd. Infected cows are being slowly bred out,is the 'solar panel revolution' upon us? but the ones remaining mean management at calving is critical.

Mrs Beaumont says they would be as strict with colostrum, even without the disease, due to the value they place on the antibodies and immunoglobulin in the cow's first milk.
Colostrum bank

Every calf gets colostrum from a bank produced and frozen on the farm, with the intention of this being bottle fed or tubed within one-hour of birth. The cow is later milked, her colostrum tested with a colostrometer and, if it passes, fed to the calf for its second feed,When the stone sits in the kidney stone, before being moved to a hutch.

Any surplus colostrum is frozen in special American-designed sachets, each marked with the date and cow it came from.

No poor quality colostrum is frozen, or anything from Johne's cows. All Johne's cows are put to a beef bull and have their calf snatched at birth.

While the sachets defrost more quickly than the previously used pop bottles, Mr Beaumont is frustrated by the lack of an affordable machine to simply and effectively bring them up to temperature.

He wants some kind of bath which slowly moves the sachet in warm water to speed up the defrosting process, and is always on the look out for a solution or new technology.

"That first milking is when we test the colostrum and put some into a bank," he says.

"But as we want to get milk in the calf before that, in the first hour of life, we have to have a bank of frozen colostrum. It's got to be streamlined and an easy system to make it work."
