Footage of mud-caked sheep struggling to walk under the weight has been published by an animal welfare lobby group, and will be investigated.
Video footage was shot in Southland last weekend at a property Save Animals From Exploitation (SAFE) claims has had ongoing issues with winter grazing.
Photographs taken early last month at the same property show sheep standing in thick mud.
MPI animal welfare and NAIT compliance regional manager Murray Pridham said while the MPI had not been notified of the video or received a complaint from SAFE, it would contact the organisation for more information and the location of the farm so an inspection could be conducted to establish any welfare issues.
“MPI inspectors have been supporting efforts to educate farmers about their responsibilities during winter-grazing season,” Pridham said.
