Landwirt überprüft die Daten des Viehs - Stock-Fotografie

A shot of a male farmer with a free-range Aberdeen Angus cow, in a farm yard in Northumberland, North East England. The cattle have been bought from a trusted seller and are double tagged to allow farmers to record the cow's body temperature, health and medication history and the composition of each cow's milk. The tags also let farmers know when a cow has been fed to prevent overfeeding.
