I love the sound of cows grazing... However, if that big-ol-boy was in my yard, I'd pay attention.
Can't see if there's anything swingin' 'tween his legs, but there's been several folks killed by bulls around here over the years. A friend was beaten up real bad by a "little" Jersey bull 20 years ago.
To put you at ease: he doesn't get there, and neither do the ladies, but the calves sometimes manage to slip through the hawthorn hedges (something they do only once...). I can deal with them, but the day anything bigger shows up, I'll call the neighbor to come and recover his property...
That animal doesn't have the body form of a steer, to me anyway.
It's a local race, the Belgian Blue. Partial quote from Wikipedia: The Belgian Blue is a breed of beef cattle from Belgium. Alternative names for this breed include Belgian Blue-White; Belgian White and Blue Pied; Belgian White Blue; Blue; and Blue Belgian. The Belgian Blue's extremely lean, hyper-sculpted, ultra-muscular physique is termed "double-muscling". The double-muscling phenotype is a heritable condition resulting in an increased number of muscle fibers (hyperplasia), instead of the (normal) enlargement of individual muscle fibers (hypertrophy). This particular trait is shared with another breed of cattle known as Piedmontese.
Both of these breeds have an increased ability to convert feed into lean muscle, which causes these particular breeds' meat to have a reduced fat content and reduced tenderness. The Belgian Blue is named after their typically blue-grey mottled hair colour; however, its actual colour can vary from white to black.
