we did pretty well in angola.  tse tse fly was nearly erradicated in the fucking 1950s. we had more cattle than we could imagine from our starting point in portugal (unironical, those who had 10 cows, went to africa and got 1.000 cows). lobito and luanda ports were among the busiest in the southern hemisphere. south africa also is (was?) awesome in horses and cattle commerce. cape and durban had huge ports.
