This article is fantastic. I wonder what on earth was in the grass in New Zealand?
According to this article the grass was so potent in 1892 that the wethers on one farm started giving milk. Wethers are castrated male sheep, not really much need for milk there.
Another farm had to stop breeding as ‘their progeny were so precocious under the influence of the abundant feed’ that maiden ewes and wethers also gave milk years earlier.
If this amazing grass caused sterile males and unmated females for give milk, what do you think could have happened to the sheep that were supposed to give milk! Yikes!
