Sheep show a marked increase in heart rate when isolated from other sheep. When a sheep was separated from other sheep by a fence, she stayed calm as long as she could see her companions. However, if the fence was...

Reducing the [barren] space allowance from 0.99 to 0.62 sq.m per lamb reduced feed intake and average daily gain. .. There was no effect of pen size on plasma epinephrine, norepinephrine or cortisol concentrations. .. The results show that the...
