Blood Levels of Calcitonin in Bulls of Varying Ages

Blodnivåer av calcitonin hos tjurar av olika åldrar.

Abstract

Blood levels of calcitonin (CT), calcium (Ca), inorg. phosphate (P) and alkaline phosphatase (ALP) in 27 bulls of Swedish Red and White Breed (SRB) and 21 Swedish Friesian Breed (SLB) were studied. There was a significant lowering of Ca, P, ALP and CT with increasing age. The fact that the osteopetrotic syndrome is increasing with age in bulls and that the CT level in blood is decreasing with age does not support the idea that an increased CT discharge could be responsible for the osteopetrotic syndrome in bulls.

Sammanfattning

Nivåerna av calcitonin (CT), kalcium (Ca), oorganiskt fosfor (P) och alkaliskt fosfatas (ALP) i blod undersöktes på 48 semintjurar (27 SRB- och 21 SLB-tjurar). Blodnivåerna av samtliga undersokta parametrar sjönk med stigande ålder. Det faktum, att de osteopetrotiska lidandena ökar med stigande ålder och att CT-nivåerna i blodet sjunker med åldern, stöder inte idén om att en ökad CT-insöndring skulle orsaka osteopetros hos tjurar.
