In order to collect semen from the bull for artificial insemination the workers made the bull mount a cow kept only for this purpose, and at the moment of penetration the penis was skillfully diverted to the side and the semen collected in a bottle. The cow's back was totally deformed after countless mounts by bulls, I don't know for how many years and how many times per day. The pig used for radioactive experimentation had his semen collected. To arouse the pig, a sow wasn't necessary, a skin covered chairback was sufficient. A technician wearing a rubber glove masturbated the pig and collected the semen.
People are thoughtless or feel themselves immune.
I saw a young vigorous bull going to his execution like a human. After the bull fell silent the butcher ordered him to move. After a while he stood up and went silently, not resisting, to the slaughter. A few days later I had a dream which I reproduced in the woodcut seen above. In a seafood store I saw a small lobster, the last unconsumed, left in the crushed ice.
