Abstract

Proljevi uzrokovani goveđim koronavirusom i rotavirusom u teladi spadaju u gospodarski
najznačajniji zdravstveni problem na farmama mliječnih i mesnih pasmina goveda.
Gospodarski gubitci posljedica su uginuća teladi, a doprinosi im trošak liječenja, dodatan rad
oko bolesne teladi, smanjen prirast i veći utrošak hrane na takvo tele. Telad koja se izliječi od
bolesti uzrokovane proljevom, zaostaje u rastu i razvoju, zahtjeva više ljudskog rada te se na
kraju na takvoj teladi gubi profit. Starost teleta je bitna kod pojavnosti proljeva, novorođena
telad je najosjetljivija u prvih mjesec dana života, a sa starošću se rizik od obolijevanja
smanjuje. Infekcije su najčešće mješovite i uzrokuje ih skupina više uzročnika kao što su virusi,
bakterije i protozoi, te mogu nastati kao posljedica lošeg menadžmenta na farmama gdje
pripadaju pogreške u hranjenju, loša higijena, ne provođenje preventivnih mjera te drugih
okolišnih čimbenika. Za prevenciju bolesti najbitnije je pridržavati se primarnih i sekundarnih
biosigurnosnih mjera te redovno provoditi imunizaciju krava te tako putem kolostruma pasivno
imunizirati telad. Zoonotski potencijal je prisutan kod oba virusa zbog mogućnosti mutacije i
međuvrsnog prijenosa.

Abstract (english)

Diarrhea caused by bovine coronavirus and rotavirus in calves is one of the most
economically significant health problems on dairy and meat cattle farms. Economic losses are
the result of the death of calves, and are contributed by the cost of treatment, additional work
around a sick calf, reduced growth and higher consumption of feed for such a calf. Calves that
are cured of the disease caused by diarrhea lag behind in growth and development, require more
human labor, and in the end profit is lost on such calves. The age of the calf is important in the
occurrence of diarrhea, newborn calves are most sensitive in the first month of life, and with
age the risk of the disease decreases. Infections are most often mixed and are caused by a group
of multiple agents such as viruses, bacteria and protozoa, and can arise as a result of poor
management on farms, including mistakes in feeding, poor hygiene, failure to implement
preventive measures and other environmental factors. For disease prevention, the most
important thing is to adhere to primary and secondary biosecurity measures and to regularly
immunize cows and passively immunize calves through colostrum. Zoonotic potential is
present in both viruses due to the possibility of mutation and interspecies transmission.
