Dio teladi oteljenih na mliječnim farmama ili je neprikladan ili nije potreban za zamjenu muznog stada i kao višak se prodajom izlučuje iz uzgoja. U cilju utvrđivanja modela korištenja muške i križane teladi u mliječnim farmama u sustavu kontrole mliječnosti u Republici Hrvatskoj, anketirano je 1717 upravitelja mliječnih farmi. Najvećim dijelom muška telad prodaje se kao sisajuća ili mlada telad, a samo 26,6 % farmi je telad zadržalo u tovu do kategorije utovljene junadi. Prosječna dob pri prodaji je iznosila 47 dana, a do 30 dana starosti mušku telad je prodalo 56,8 % farmi. Očekivano, holštajn muška telad prodaje se ranije u odnosu na mušku telad drugih mliječnih pasmina. Pasmina ima veliki utjecaj na prodajnu dob i cijenu muške teladi, a simentalska telad je prodavana po najvećoj cijeni i u najstarijoj dobi. Velike farme ranije prodaju mušku telad, a između veličine muznog stada i dobi pri prodaji utvrđena je negativna korelacija (p<0,01). Muška telad prodavana je po prosječnoj cijeni od 332,14 €, a prodajna cijena bila je usko povezana s pasminom i dužinom uzgoja teladi na farmi. Prodajna cijena i razdoblje zadržavanja muške teladi na farmi razlikovala se između regija u kojoj se farme nalaze. Razlike u prosječnoj prodajnoj cijeni prema županijama rezultat su različitih pasminskih struktura i veličina muznih stada na mliječnim farmama. Utvrđeno je da na modele ekonomskog korištenja muške teladi značajan utjecaj imaju pasmina, veličina farme i regija u kojoj se farme nalaze. On dairy farms a certain number of calves are either unsuitable or not needed for the replacement of the milking herd. Therefore, they are removed from breeding being sold as a surplusage. To determine the model of using male and crossbred calves in dairy farms in the milk production control system in the Republic of Croatia, 1,717 managers of dairy farms were surveyed. Most male calves were sold as suckling or young calves, and only 26.6% of the farms kept the calves for fattening up to the category of fattened beef. The average age at sale was 47 days, and 56.8% of farms sold male calves up to 30 days of age. As expected, Holstein male calves were sold earlier than male calves of other dairy breeds. The breed has a significant influence on the age at sale and price of male calves, Simmental calves were sold at the highest age and for higher prices. Large farms sell male calves earlier, and a negative correlation was found between the size of the milking herd and the age at sale (P<0.01). Male calves were sold for an average price of 332.14 €, and the selling price was affected by the breed and the length of period in which the calves were reared on the farm. The selling price and time spent on the farm of male calves differed between the regions in which the farms were located. Differences in the average selling price by county result from different breed structures and different sizes of milking herds. It was found that the economic models of the use of male calves were significantly influenced by the breed, the size of the farm and the region where the farm is located.
