In Spain, young bulls are slaughtered about 14 months. After slaughter, the carcasses remain in the slaughterhouse for less than 7 d. The present work collects this information and makes an attempt to analyse the response of the meat during the first 7 d of maturation to the oxidation of the fatty acids. Natural antioxidants in beef ensure fatty acid stability during first 7 d postmortem. Beef from pasture-fed meat includes a higher natural antioxidant content than grain-fed meat.

The research was carried out on cows fed with a conventional or green fodder diet in order to determine the physicochemical characteristics and mineral content in milk. The data show similar results except for the fat content, which is higher in milk coming from cows fed with hydroponic barley. Minerals were in the range reported elsewhere. The hydroponic fodder system seems to be an ideal solution in places where it is not possible to grow fresh fodder or where pasture grazing is nonexistent.

A study was conducted on the effect of separated manure as bedding material on milk quality as manifested in the somatic cell count. Cows were maintained in a loose barn in cubicles bedded with fresh separated cattle manure (SCM) with 40 % solids content. Analyses were conducted on 242 primiparous Black-and-White PHF cows in the course of a 305-day lactation. Conducted analyses showed that SCM as bedding in cow cubicles had no effect on somatic cell counts in milk of primiparous cows.
