This was very interesting, not for the research value, but for the fact that they couldn't complete the research because by 8 months their herd was so unhealthy they were dying.
Adding in the comments and treatments for "numerous eye infections and fungal issues" "and as they got sick they were treated as vet directed" I'd wager there was a huge issue going on there.
I'd also be curious to know what "other animals" were kept in the lab - they claimed to keep the temp at 68 for the comfort of the other animals, was that the ultimate downfall, or they really did screw up the diet that bad?
Intriguing!
