They are also able to discriminate between familiar individuals, and among humans. Cattle can tell the difference between familiar and unfamiliar animals of the same species (conspecifics). Studies show they behave less aggressively toward familiar individuals when they are forming a new group.  Calves can also discriminate between humans based on previous experience, as shown by approaching those who handled them positively and avoiding those who handled them aversively.  Although cattle can discriminate between humans by their faces alone, they also use other cues such as the color of clothes when these are available. 
Super Cow on Steroids? The Barry Bonds of Bulls? The gigantic super cows are massive and full of muscle like advanced body builders.
You’ve heard the expression, everything is bigger in Texas, well that isn’t true in the small country of Belgium. These Super Cows or better known as The Belgian Blue Bulls are genetically mated cows that scientist farmers have been working on for years. Using natural selection, they are able to artificially inseminate cows with scientifically selected sperm from the strongest bulls.
No steroids here. Each generation of new cows become bigger and stronger with double muscle mass for leaner and better beef.
I put some links to other videos and some other articles I’ve read on these super cows if you want to check ’em out. How much healthier is this super cow meat vs regular cows and does it actually taste better? I would think it would make a REALLY TOUGH STEAK... no phun intended.
