Beef Central today reports that Phoenix has had its ability to export to China suspended on the basis of 2 shipments with grain fed Bos taurus cattle having mortalities exceeding 1%. The journeys were in May (from Freo) and July (from Portland....ie Bos taurus from a cold southern mid-winter climate). Oh yeah and they were over 600kg. Contributor to both high mortality voyages (1.45 and 1.5% respectively)....heat stress.
Well....what a surprise!! Every bit of science we have about heat stress thresholds in Bos taurus cattle indicates that they have the potential for heat stress crossing the Equator...fatten them up, ensure they are over 600kg...and then send them from Portland....mid winter....after a voyage from Freo in May has already failed???
The Dept is currently asking for submissions on Heat Stress Risk Assessment in sheep to the Middle East.....perhaps they should do the obvious thing and reassess their totally flawed HSRA for cattle (to any location) also.
