I have been asked to attend a meeting on the above subject - basically it means breeding cattle to produce less methane, as it is possibly an inherited trait. A recent published paper did not link it to any particular breed but said that there are likely to be animals in most breeds that produce less methane than others on particular diets. A brief read around the subject suggests it may be linked with feed efficiency. How do cattle breeders feel about possibly changing their current breeding programmes to aim for reducing methane production? (Personally I do not agree with the whole “cattle causing global warming bandwagon” as you might expect but if government officials like the sound of this, we may have to think about it.) Anyone like to comment? Anyone already doing this?
