Seven cows on a Southland dairy farm have been euthanised after being found stuck in the mud with insufficient water.
Ministry of Primary Industries animal welfare officers recently visited the farm in Riverton, near Invercargill, following a complaint.
They found about 2000 cattle surrounded by mud, with insufficient water.
Five dairy heifers had to be euthanised by animal welfare inspectors on advice from private veterinarians, two other heifers were euthanised by the farm manager.
MPI director of compliance and response Glen Burrell said the farmer had been directed under the Animal Welfare Act to relocate the remaining cattle and was given further direction on how to reduce the impact of mud on cattle.
A veterinarian assessment of all cattle was being carried out.
"We'd remind all farmers that a well-planned winter grazing system supports good animal health and welfare. It ensures animals have sufficient and appropriate feed, access to plenty of clean water, and the ability to move freely to and from their feed and water.
"While most farmers work hard to do the right thing and have improved their winter grazing practices over recent years, this is an important reminder to plan ahead," Burrell said.
MPI's investigation was ongoing and it would consider further action in due course.
