Cowpats could soon be smelling sweeter if a new project takes off.
Scientists are experimenting with putting pleasant-smelling plants and oils into the food that cows eat.
Herbs like thyme and mint will be added to their daily diet, which, among other things, will make cowpats smell a bit nicer.
Improve conditions for cows
It's hoped the plants will be a safe, 'green' alternative to things like antibiotics which cows are given at the moment.
The point of the research is to improve conditions for cows, help the environment and make the rearing of cows for their meat more efficient.
