Zimbabwe's poultry producers criticised the government over the H5N8 avian influenza outbreak, detected in May 2017, which has cut table egg supply and raised prices. The producers asked for the 40% duty on imported hatching eggs to be waived and for policies to compensate affected farmers.
Lower domestic poultry output reduces local feed demand, which is bearish for regional grain and meal. The duty dispute affects import costs for hatching eggs, but the price effect on global commodities is small.
After 175 past bearish disease events, Corn moved a median +0.0% over 5 sessions (51% higher; middle half -1.7% to +1.5%), and +0.6% over 20.
