British scientists are investigating whether replacing traditional breeds of cow with a “double muscled” breed could be better for the environment.
Cattle farming is a major source of greenhouse gases because the animals need land to graze, and they produce vast volumes of flatulent methane, which is 80 times more potent for global warming than carbon dioxide.
Britain currently has cow herds and breeds specifically for dairy, some only for beef, and some cross-breeds which can be used to produce both meat and milk.
The Department for Environment, Food and Rural Affairs (Defra) has funded a study with more than £10,000 of taxpayers’ money in which scientists at Harper Adams in Shropshire, a specialist agricultural university, will investigate possible ways of reducing emissions.
Possible routes being studied include increasing the use of dual-use cows instead of dairy-only herds and also swapping traditional British breeds for more muscular breeds that produce more meat.
Scientists conducted a modelling study using farm data and previously published information to see if these switches would improve emissions.
Swapping the traditional black and white dairy cows, holsteins, for dual-use cattle was one aspect of the study. The second aspect involved seeing if swapping herefords or angus cows for super-muscular breeds would be beneficial.
The brief from Defra mentioned the possibility of pivoting to European breeds, such as the charolais or Belgian blue, but the scientists focused on the British blue.
The British blue has a gene mutation that allows it to naturally grow 20 per cent more muscle mass compared with other breeds while the animal is fine-boned and docile by nature, which leads to high volumes of meat produced per animal.
“British blue cattle tend to be more efficient with faster growth
rates, higher carcass weights and a lower age at slaughter, which
reduces their carbon footprint compared with the angus breed,” said Prof
