This reaction is partly caused by the release of histamine from certain cells in the body. Xyzal is an antihistamine, which means it blocks histamine from binding to histamine receptors and causing allergy symptoms. Because histamine is responsible for many of the symptoms of allergies, blocking it can be helpful.
The Chianina is both the tallest and the heaviest breed of cattle. Mature bulls stand up to 1.8 m (5 ft 11 in), and castrated oxen may reach 2 m (6 ft 7 in). It is not unusual for bulls to exceed 1,600 kg (3,500 lb) in weight. Males standing over 1.51 m (4 ft 11 in) at 12 months are considered top-grade.
The Simmental, one of the more docile and easy to manage breeds, is known for a long straight topline with deeply muscled back and loin. Medium to large cattle with strong bones, bulls typically weigh 2200 to 2800 pounds at maturity and cows 1200 to 1600 pounds. The females have a productive lifetime of ten to twelve years and high milk production. Simmental are spotted, occasionally with just a few white markings.
