Abstract Bali cattle ( Bos sondaicus ) is an indigenous bovine domesticated in Indonesia and harboring prominent genetic traits for livestock production. Parasite infection, however, may act as a large constraint the husbandry. Bovine coccidiosis well-known major gastrointestinal protozoa which causes significant loss due to intestinal damage drug cost. Coccidia wall derived from thick structur...

The aim of this study was to evaluate the effect high doses calcium bentonite on blood parameters, anticoccidial activity and intestinal histology broiler chickens. Three undred sixty one-day old broilers were distributed into three treatments (T+VE, T-VE, TB )with replicates. Amprolium added feed positive control group, powder nothing T-VE group. Coccidiosis induced day 14, birds kept until 49...

Avian coccidiosis, an intestinal disease caused by protozoan parasites of the genus Eimeria, occurs worldwide. It is considered to be one of the most economically important diseases of domestic poultry. For many years, prophylactic use of anticoccidial feed additives has been the primary means of controlling coccidiosis in the broiler industry and has played a major role in the growth of this i...

Drug resistance is a problem wherever livestock are raised under intensive conditions and drugs are used to combat parasitic infections. This is particularly true for the anticoccidial agents used for the prevention of coccidiosis caused by protozoa of the apicomplexan genus Eimeria in poultry. Resistance has been documented for all the dozen or so drugs approved for use in chickens and varying...

Eimeria intestinalis infects rabbits, causing severe intestinal coccidiosis. Prolonged anticoccidial drug use might lead to coccidia resistance and residues in food. Thus, vaccines are required control rabbit In this study, recombinant E. 14-3-3 GRA10 proteins (rEi-14-3-3 rEi-GRA10) were obtained via prokaryotic expression used as subunit vaccines. Fifty 30-day-old rabbits randomly grouped foll...

In-feed Medication has been used for a long time to prevent coccidiosis, a worldwide protozoal disease in rabbits. Florfenicol (FFC) has been widely used in veterinary clinics for bacterial diseases treatment. Therefore, the use of combinations of coccidiostats with FFC in rabbits is common. In the present study, we aimed to evaluate the effect of three coccidiostats, sulfaquinoxaline (SUL), ro...

The hypothesis tested was that exposure of broiler chickens to an electromagnetic field (EMF) may reduce the signs of coccidiosis infection, based on recent insights into immunology. The experiment had a 2 x 2 factorial design. An uninfected and an infected group did not receive further treatment, whereas the other uninfected and infected groups were subjected to EMF treatment. In the cages of ...

Objective (s): The green synthesis of copper nanoparticles using metabolites of microorganisms has gained much interest in recent years. In this work, it was studied optimization of copper nanoparticles synthesis using E. coli and its antifungal activity.Materials and Methods: The copper nanoparticles were synthesized by Escherichia coli. Effect of copper nitrate concentration and temperature w...
