Morphometric and Histopathological Evaluation of a Probiotic and its Synergism with Vaccination against Coccidiosis in Broilers
A probiotic containing Bacillus mesentericus, Clostridium butyricum, and Streptococcus faecalis [AVITEAM] was evaluated in damage control and synergism with vaccination against coccidial infection in broilers, using morphometric measurements and histopathological observations. It was mixed in feeds and vaccination was done by inoculating birds with an attenuated live vaccine containing Eimeria ...
متن کاملConcurrent aflatoxicosis and caecal coccidiosis in broilers
A farm of two broiler flocks fed from one day old to 56 days of age a diet naturally contaminated with high level of Aflatoxin (AF), were suffered from caecal coccidiosis at 35 days of age Aflatoxin levels in feed commodities and mixed feed were determined using ELISA test. Results of ELISA showed that the average level of corn, soybean and mixed feeds contamination with aflatoxin were 1915, pp...
متن کاملEffect of Zinc on Humoral and Cell-Mediated Immunity of Broilers Vaccinated Against Coccidiosis
BACKGROUND The aim of the present study was the comparison of humoral and cell-mediated immunity in broilers fed with different levels of zinc during a coccidiosis challenge. METHODS One hundred and forty-four one-day-old broiler chicks were used with three dietary zinc (40, 120 and 200 mg/kg). At 14 d of age, all birds were inoculated orally with 5×10(3) sporulated oocysts of E. Tenella. At ...
متن کاملControl of Coccidiosis in Calves by Vaccination
The immunizing effect of inactivated sporulated oocyst and inactivated sonicated vaccines against bovine coccidiosis was observed in calves. Indirect haemagglutination (IHA) test was developed for detecting antibodies to coccidian. Serum antibody levels in calves were measured against soluble oocyst (sporulated) antigen. IHA antibody titer was significantly higher (P<0.05) in calves vaccinated ...
متن کاملVaccination of chickens against coccidiosis ameliorates drug resistance in commercial poultry production
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...
