20.500.12556/RUL-186092 Vpliv krmljenja rudninskih snovi na pojav poporodne mrzlice pri kravah molznicah diplomsko delo The effect of mineral nutrition on the incidence of hypocalcemia in dairy cows B. Sc. thesis Hipokalcemija je pogosta presnovna bolezen krav molznic v obporodnem obdobju, ki pomembno vpliva na zdravje živali, uspešnost reprodukcije in ekonomiko prireje mleka. Namen naloge je bil predstaviti vzroke nastanka bolezni, dejavnike tveganja ter možnosti preventive in zdravljenja, predvsem z vidika prehrane. Naloga temelji na pregledu domače in tuje znanstvene ter strokovne literature. Ugotovili smo, da klinična hipokalcemija prizadene 5–10 % krav molznic, subklinična oblika pa do 50 % živali. Tveganje za pojav bolezni se povečuje z zaporedno laktacijo, višjo mlečnostjo, prekomerno telesno kondicijo in neustrezno prehrano v času presušitve. Ključno vlogo pri preprečevanju bolezni imajo ustrezna oskrba z rudninskimi snovmi ter pravilno uravnavanje kationsko-anionskega ravnotežja obroka. Raziskave potrjujejo, da uporaba anionskih soli učinkovito zmanjšuje pojav poporodne mrzlice, saj izboljša vzdrževanje homeostaze kalcija. Kot učinkovita preventivna ukrepa sta se izkazala tudi uporaba zeolita A in dodajanje vitamina D, pomembno vlogo pa imajo še peroralni kalcijevi pripravki po telitvi. Hypocalcaemia is a common metabolic disease of dairy cows during the periparturient period, significantly affecting animal health, reproductive performance, and the economics of milk production. The aim of this thesis was to present the causes of the disease, risk factors, and the possibilities for prevention and treatment, especially from nutritional point of view. The thesis is based on a review of domestic and international scientific and professional literature. It was found that clinical hypocalcaemia affects 5– 10% of dairy cows, while the subclinical form affects up to 50% of animals. The risk of disease occurrence increases with increasing parity, higher milk yield, excessive body condition, and inadequate nutrition during the dry period. Adequate mineral supply and proper regulation of the dietary cation–anion balance play a key role in disease prevention. Research confirms that the use of anionic salts effectively reduces the incidence of milk fever by improving the maintenance of calcium homeostasis. The use of zeolite A and vitamin D supplementation have also proven to be effective preventive measures, while oral calcium preparations after calving also play an important role. krave molznice poporodna mrzlica rudninske snovi hipokalcemija homeostaza kalcija diplomska dela dairy cows milk fever minerals hypocalcemia calcium homeostasis true false false K.
