This week, selective breeding appears to be invading my life. On Thursday, I received a catalog from Heifer International, a charity that does great work giving animals to the international poor to improve their diet and economic circumstances. Part of the program is that the gift of a goat/cow/sheep will create a self-replicating cycle of improvement as the animals give birth and the new animals are given or sold to other poor families. So imagine my surprise when Heifer asked me to send them $120 so they could send two female goats to a family in need.
This reminded me of a scene from The King and I, the Rogers and Hammerstein musical. The King of Siam decides to send a pair of male elephants to America to help President Lincoln win the Civil War. When Anna, a British schoolteacher, suggests that perhaps two male elephants would not provide Lincoln an army of elephants, the king agrees and decides to send two female elephants.
In the modern world, these are amusing errors. However, they represent a belief that modern people should understand the basics of breeding. Looking at our recent readings, I was surprised how suddenly modern-style selective breeding made an appearance. Walter of Henley, for example, barely gives any advice on how animals should be bred. Although he acknowledges pigs and sheep should be “sorted”, he gives no advice on how to pick out the better stock or how they could be induced to breed and produce better offspring 1. This is in context of relatively extensive discussions on the proper feeding, housing, and weaning of animals (particularly cattle). This distinction is particularly pronounced in the case of cattle, where Walter makes no mention of good breeding. Furthermore, he seems to be sure that oxen and horses must be bought, rather than taken from one’s own flock 2. Given his apparently large stock of cattle, why would Walter buy oxen unless he didn’t believe high quality oxen and horses could be created by selective breeding?
