More than 20,000 sheep were lost in the recent snow blizzard, and it may be next month before all the dead animals are found and counted.
Many farmers faced serious dangers as they tried to reach their animals
The news emerged at a meeting of the agriculture committee at Stormont.
It is estimated that almost 800 farms were affected by the severe snow storm.
With snow still lying in some high parts of Northern Ireland, dead animals are still being recovered, but the committee heard that one sheep was found alive 25 days after the blizzard.
An official from the Department of Agriculture told the committee that as of 14: BST on Tuesday, the number of dead animals collected was:
20,179 sheep (including 15,195 lambs)
603 cattle
Comment: It's actually a sun halo; a sun dog is something like this.
So sun halos around the sun are appearing in Cuba now? Well that rules out the earlier 'explanation' that they were the result of ice crystals forming in cold environments such as the Arctic Circle.
In fact, they have appeared in the UK and Russia recently.
This is more evidence that the upper layers of Earth's atmosphere have rapidly cooled in recent years.
