productivity of dairy and beef cattle resulting in substantial economic
losses. Current preventive and treatment strategies rel...
The study encompassed collecting of honey samples from diverse honey producers from the territory of Vojvodina Province and the analysis thereof for the presence of antibiotic and sulfonamide residues. Having in mind the actual clinical information and epizootical situation, it is most likely that antibiotics are still in use in apiaries. In this r...
Introduction. Artificial insemination of sows with cooled semen has become a
routine practice in the swine industry and has almost completely ruled out
natural mating. The storage time of the cooled semen and preservation of its
qualitative parameters are of the upmost importance and depend partly on the
semen extender used. The aim of this study w...
