Heat stress on the Al Kuwait.
So update 3 is now available from RETWA. The exporters are patting themselves on the back for the low mortality rate and claiming minimal heat stress.
But the Wet Bulb Temperature graph tells a pretty terrible story. By the industry's own admission WBT above 29 is danger zone and this was exceeded for numerous days with no response. In fact on one deck, WBT went up to 32. The company claimed that only 190 sheep were panting but as the temperature peaked at 1am, one wonders whether some of the panting went unobserved...usually only skeletal ship crew up at that time and not vets, stockies or independent observers.
The HOTSTUFF model itself has heat stress threshold at 28.6 for adult Merinos and 26 for Merino lambs coming from this part of Australia at this time of the year. There is no doubt that these sheep suffered....they just didnt die. That does not mean it is acceptable animal welfare.
