At the time of the inspection, Pelvin was responsible for 75 sheep and 27 lambs.
"As a result of the lengthy and combined effects of minimal feed and heavy parasite burden the inspection identified 20 emaciated sheep along with six dead in and around the water race. Another sheep was found tangled in fencing wire.
"Thirteen of the twenty sheep required euthanasia to end their suffering. The other seven were able to be managed in order to save their imminent lambs," said MPI national animal welfare and NAIT compliance manager Gray Harrison.
"These animals were Mr Pelvin's responsibility and he failed them.
"Mr Pelvin did not give them the feed and veterinary treatment they needed and as a result they suffered unnecessary pain and distress."
