China Mengniu Dairy Co Ltd, one of China's leading dairy producers, has upped its corporate social responsibility game by providing free training to ranchers who supply raw milk to the company.

The training program - Ranchers University - started in 2014 and has provided free training in scientific cattle breeding and feeding to roughly 3,500 ranchers, according to the company.

More than 800 cattle ranches have benefited from the technological support from Mengniu which sent 150 professionals from home and abroad to give on-site instruction.
