SIR, – Congratulations to Jim Brown on writing an excellent piece of ammunition to get back at these so-called 'experts' who blame our cattle for global warming.

It would be far safer to sleep in a cowshed full of cattle, than trying to sleep alongside an idling engine using up all the available oxygen and gradually filling a garage with deadly fumes.

Yet this is almost what is happening 365 days per year on our crowded roads filled with slow running engines and burning clutches – and often only one person inside the vehicle.

Many years ago, it was said that someone had invented an engine that ran on water. Let us hope that the hydrogen engine will eventually take over, with no 'fuel tax', no fumes and a fill up from the nearest water tap.

It was also interesting to read about that old excellent Charolais bull, Kersknowe Festival. We used to have pedigree A-As but over the years became disappointed with the small size of calves born by MMB and SMMB Angus bulls. Our cows were larger than usual and would suckle an extra calf no bother.

Then, on a visit to Smithfield, I saw a couple of steers by the Charolais bull MMB Argent which really impressed me. I ordered 45 straws of semen which, luckily, got doubled up and we had calves on the ground which were a joy to look at.

Every cross-bred bull calf was kept for breeding and were sold on, with many repeat customers.

Kersknowe Festival followed and the results were again excellent, with several show-winning heifers.

However, where do we go next? We tried Limousin, Simmental and British Blues, but nothing would give us the quality of that first cross.

We are now organic milk producers getting too low a milk price and giving it all and more for the price of organic feed!
