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.
A mature bull can weigh anywhere from under 2000 lbs to over 3300 lbs. The current average is around 2700 lbs. But, it all depends on each individual bull, and his breeding. Mature bulls can weigh up to 2000-2800 lbs for the more average type breeds including Angus, Holstein, Brahman, Galloways, Charolais, and many others.
