It was during the already described picnic in the Rift Valley that I first came across the Maasai method of birth control in sheep!
You will recall that when we arrived to the tree we had selected, it was already “booked” by Maasai boy herders and their sheep and goats. We eventually managed to get a tree for our picnic albeit reeking of sheep and goats urine and covered in faecal pellets!
It was during our negotiations with the herders that I noticed that a ram was actively pursuing a ewe that was clearly on heat. After a while the female accepted the male and the ram mounted her. At that time I realized that the latter was wearing a leather apron that -like a reverse chastity belt of medieval times- stayed between its penis and the ewe’s vagina, frustrating the act!
Earlier I have pondered on how the Maasai and other pastoralists synchronised their lambing to happen at the right time when the flocks included males and females grazing together. My conclusion was that it was due to the ewes not going on heat until the right time. To see this rather clever contraceptive method gave me another reason for the animals having their lambs at the right time.
