Ok so we sent a highland breeding bull (only 1 cover) to slaughter. He was 2yrs old. when we got the meat back, after having steaks from him it left a kind of "film" in our mouths. That was the first time we've sent one off for highland and being a bull. So we are not sure if the film is the lean highland or that he was a bull. Does anyone know what it is? We sent a Hereford bull off too but I don't remember a film or at least not as noticeable as the highland. Thanks
