China has resumed imports of genetic material for cattle, buying more than 92,500 batches of semen from Australia and Canada worth about $700,000 by the end of August, Reuters reports. Shipments are made according to a new standard that allows the import of material from only 10% of the best bulls in the producing countries. The measure aims to increase the productivity of beef and milk and reduce the cost of importing beef and dairy products, which reaches 30 billion dollars a year.
