Back in the day, about 1990, I worked for a company that sold Champion Breed Bull seman. While I know how they collected the sample, don't ask me to tell you.
Anyway, in the sales brochure, they showed the national champion bull from 1980. It was all big and fat and rolly polly. With the trend to lower fat diets, they started breeding more muscular cows. The national champion bull for 1990 was all muscular and ripped. Think the difference between Arnold when he was Mr. Universe and when we was the Ex-Governor.
The problem with Beef, one that this cow overcomes, is how much we have to feed it to get meat. It takes about 15 pounds of feed to make 1 pound of beef, 6 pounds of feed for 1 pound of pork and 5 pounds of feed for 1 pound of chicken, the Department of Agriculture estimates. I think the Belgian Blue can grow a pound with much less feed than a cow. Probably down around the rate of pigs. That alone makes it worth the effort.
We should breed more of them to save the environment!
So how did they collect those seman samples?
