Abstract
Negativni energetski balans i ketoza predstavljaju veliki problem na farmama. Učestalost ovih poremećaja se povećava sa velikom mliječnosti mliječnih krava, te se problem još produbljuje neadekvatnom hranidbom ili nepovoljnim vanjskim čimbenicima. U radu se pokazalo da se pojavnost ketoze na pet naših farmi kreće od 4 do 26 % što predstavlja veliku varijabilnost. Problem predstavljaju postotci ketoze koji se kreću iznad 10 % te se posebno kod ovih farmi treba posvetiti pozornost pripremi krava na laktaciju. Pravu uzročno posljedičnu vezu treba tražiti u hranidbi krava na ovim farmama i to posebno u kasnom graviditetu, suhostaju i pri početku laktacije. Veliki nedostatka energije u prijelaznom razdoblju praćen sa slabijim apetitom krava nakon teljenja, te velikom proizvodnjom mlijeka izaziva hipoglikemiju, lipomobilizaciju masti iz tjelesnih rezervi, te dovodi do naglog opadanja tjelesne mase. Uz veliku lipomobilizaciju i manjak energije stvaraju se odlični preduvjeti za nastanak ketoze. Ovaj oblik ketoze nema simptome te ga je vrlo teško dijagnosticirati
Abstract (english)
Negative energetic balance and the ketosis represent a big problem on the farms. The frequency of these disorders is increasing with big milk production of dairy cows and the problem is deepened with inadequate feeding or unfortunate external factors. This thesis has shown that the presence of ketosis in five of our farms goes from 4 to 26% which shows big variability. The problem is the percentage of ketosis that goes from 10% and a special attention should be payed to these farms during the milking process. The true causality should be searched in feeding of the cows on these farms and especially in late gravidity, dry period and in the beginning of the lactation. The big shortage of energy during the transitional period followed by weak appetite of cows after calving and the big milk production causes hypoglycemia, lipomobilisation of the fats form body reserves and leads to a sudden decrease in weight. The big lipomobilisation and the lack of energy are great for emergence of ketosis. The real problem is subclinical ketosis which is in this paper pointed out as an important problem in cattle breeding. This type of ketosis, which has no symptoms is very hard to diagnose.
