I figured I might as well formally express my interest and submit the requested information
Former Occupation: Stud
Former Species: Bull
Former Gender: Male
New Role: Now runs the farm, and keeps the others in line. The former animals obey him out of respect, loyalty, and a bit of fear. The former scientists obey him mainly out of fear, though he has probably broken a few of them sufficiently that they don't mind staying.
Current Species: Bull-Human Hybrid (basically an enormous human with thick skin, a short tail, horns, and massive muscles. Also retained his enormous cock from when he was a bull)
Current Gender: Male
Other notes and Modifications: Bruno is probably one of the most heavily modified of the animals on the farm. The most obvious changes, aside from his new humanoid form, are his utterly absurd physical abilities. He can lift twenty tons, run at up to eighty miles an hour, and seems to have limitless stamina. He was also granted sentience, far more so than his creators intended, as he is now actually more intelligent than the scientists who created him. Bruno does have something of an addiction to sex, leftover impulses from his time as a bull. He is accustomed to being a stud, a bull used primarily for mating with the female cows, and so he has sex on the brain a lot. Fortunately, his position of authority means that obtaining sex is fairly easy, since almost no one has the guts to say no should he request it.
