AB  - On large farms of dairy cattle HF breed, very rarely achieved fertility in a herd of over 80% of cows, per year. On farms in Serbia are very few dairy farms are able to achieve fertility of over 75-77% in one year. This is related to herd of cows sterility, which is caused by multiple factors such as nutrition diet, posture, height of lactation, an organization monitoring the animals on the farm insemination procedure, training of veterinary and other staff as well as the interest of workers, motivation of workers to produce milk at the farm. In this study, with the native sperm of two bulls from the Center for reproduction, PKB Corporation, Belgrade in the fall of 2010 was insemeinated a number of cows (568) and examined the fertility of cows on two dairy farms with the use of lists to track production and reproductive status of cows on farms PKB Corporation.
AB  - Na velikim farmama mlečnih krava HF rase, veoma retko se postiže plodnost u stadu od preko 80%, na godišnjem nivou. Na farmama u Srbiji retko koja farma mlečnih krava može da postigne plodnost 75-77% u toku jedne godine. To je povezano sa stadnim sterilitetom, koji je uzrokovan od većeg broja činilaca, kao što su: ishrana, držanje, visina laktacije, organizacija praćenja grla na farmi, postupak osemenjavanja, obučenost veterinarskog i drugog osoblja, kao i zainteresovanosti radnika, tj. motivacije radnika za proizvodnju mleka na farmi. U ovom radu korišćenjem nativne sperme dva bika iz Centra za stočarstvo PKB Korporacije, u jesenjem periodu 2010 godine, osemenili smo veći broj krava (568) i ispitali plodnost na dve farme, uz primenu lista za praćenje proizvodno-reproduktivnog statusa krava na farmama PKB Korporacije.
