Two commercial Iorry consignments of 500 sheep were followed from the
United Kingdom to their destinations in southern France, one journey o
f 800 miles taking 18 hours and the other of 950 miles taking 24 hours
. Measurements were made of liveweight and skinfold thickness, and blo
od samples mere taken from 100 sheep in each consignment, two days bef
ore departure and again immediately after the journeys. The results fr
om each consignment were similar. High levels of plasma beta-hydroxybu
tyrate, free fatty acids and urea, both before and after the journeys,
indicated that the animals mere in a catabolic stale. Before the jour
ney this was probably as a result of their marketing through livestock
auctions. After the journey the animals showed evidence of dehydratio
n, indicated by increased levels of plasma total protein and albumin,
and increases in plasma osmolality and skinfold thickness. The behavio
ur of the sheep after the journeys indicated that they were all alert
and physically fit; they showed great interest in any food that was av
ailable and were only secondarily interested in drinking, and then res
ting.
