A visitor to Kruger National Park in South Africa has recorded an African buffalo calf repeatedly headbutting its mother in the udder.<br /><br />"This buffalo cow stood patiently, chewing her cud while her large calf butted her udder to make her release milk," said filmer Bob Humphries.<br /><br />"The butting looked painful to me, but the cow did not seem to mind," he added.<br /><br />The clip was filmed back in 2016.
