Human induced translocation and introduction of species have reshaped parasite fauna on a global scale. The introduction of the large American liver fluke Fascioloides magna from North America to Europe is an example of an invasive alien parasite causing significant ecological and economic damage. Recent genetic studies have shown that F. magna was...
Native goat breeds in Serbia has been recognized as an important element of regional agrobiodiversity and play an important role in the safeguarding of cultural and traditional heritage. The aim of this study was to identify the main welfare issues likely to be encountered in extensive goat farming systems with an emphasis on parasitological infect...
Recently, in many parts of the world, greater importance has been given to lamb meat as well as to the intensive production of lamb and sheep, due to demand for this type of meat at affordable prices. In Serbia, similar to most European countries, the structure of total sheep meat production comprises about 70% lamb meat and 30% sheep meat. This st...

A 40-day experiment was carried out on 6885 broilers of ROSS 308 provenience. The broilers were reared on bedding material which consisted of cellulose pellets, wood chips, peat moss, and pH...
Small Ruminant Lentivirus causes a chronic lifelong, multisystemic diseases in sheep and goats with or without clinical manifestation. Maedi-visna virus (MVV) and Caprine arthritis encephalitis virus (CAEV) are often considered together as small ruminants lentivirus (SRLV) due to their phylogenetic correlation and the interspecies transmission betw...
The importance of harmless removal of animal wastes increases with the intensification of animal breeding and with development of meat processing plants. It is irreplaceable, preventive veterinary and sanitary measure used in control of livestock diseases and zoonosis. Nowadays, it has a big role in environment protection.

The presence of hydrometra was analyzed on five dairy goat farms (one Saanen and four Alpine) in a period of one to three years, from 2013 to 2016. Total of 3,355 goats were scanned by ultrasound for pregnancy diagnosis after breeding season or out-of-season upon hormonal synchronization. Overall incidence of hydrometra was 1.37%. One farm of Saane...
Ovine brucellosis can cause epididymitis and reduce fertility in rams and therefore is an important disease in sheep and rams from economic point of view. Sometimes it causes abortions and increased perinatal mortality in sheep as well, but it primarily affects male animals. Brucella ovis was first identified in northern region of Serbia, in 2008-2...
Introduction:
Hormonal and metabolic changes, as well as energy imbalance, can affect health, production and reproductive performance of dairy cows. In the present study, we evaluated phagocytosis and respiratory burst neutrophil activity during the transition period and early lactation and compared it with biochemical and hematological parameters...

Bovine herpesvirus 1 (BHV-1) is one of the most siginificant causes of infections of the respiratory tract of cattle and immunoprophylaxis has a key role in curbing this infection. The intensity of the immune response against BHV-1 following immunization using inactivated commercial vaccines varies depending on the type of vaccine, but it is genera...
Various biotic and abiotic factors are present in ecosystem and they influence the processes of living organisms. Some agents that come into natural waterways are genotoxic. They affect genome and during mitosis and meiosis, and cause numerical and structural changes in karyotype. A research on the degree of genotoxicity on water was carried out on...

Blood was sampled from the cows immediately after parturition, and from the calves before feeding on colostrum. The examined cows and their calves originated from 5...
Some Staphylococcus aureus strains, identified as causative agents of mastitis in cattle, exhibit the ability of producing a viscous extracellular polysaccharide layer (slime), which is nowadays considered to be a virulence factor, as it promotes bacterial adhesion onto the mammary epithelial cells and protects bacteria from opsonization and phagoc...
Bovine tuberculosis caused by Mycobacterium bovis is a chronicle, infective disease associated with formation of specific inflammatory granulomas. Infection usually remains subclinical for a long period, but even when the clinical are present, they are not pathognomic. Bovine tuberculosis can spread to humans through inhalation of infectious drople...
Respiratory diseases of cattle are considered to be the most frequent causes of health problems in now days cattle industry. Among all respiratory diseases the Bovine Respiratory Disease Complex – BRDC is the most significant. BRDC is manifested with severe inflammation of respiratory tract and lungs. The disease is caused by viruses, bacteria and...
Bovine viral diarrhoea (BVD) is a worldwide viral cattle disease. Percentage of seropositive animals, especially in the countries with intensive cattle breeding ranges from 60-90%.

Since the largest number of cattle in Southern Baåka and Srem district are raised in small herds (what may considerably influence...
On large farms in our country silage presents an important part in dairy cows ration. During the process of fermentation, different kinds and amounts of alcohol, first of all ethyl alcohol, emerge in silage. Besides this, in rumen of cows fed with easily digested carbohydrates, a small quantity of ethanol can be detected. The aim of this paper was...
Antibiotic residues in milk are of great concern to dairy farmers, milk processors, regulatory agencies, and consumers. The
aim of this study was to compare the screening tests for residue detection in milk with the purpose of choosing the most sensitive
test that could prove residue quantities at maximum residue limits (MRL). The Penzyme S, Delvo-...
The abortions in sheep are important at various aspects, i.e. economical, animal healthcare or zoonotic. Abortions in sheep may occur sporadically or as enzootic outbreaks. The causative agent of the abortion is investigated if more than 2% of abortions in pregnant animals are registered within the herd. The amount of suspect material to be deliver...
