calf is placed in an individual pen, 5 by I o by 3 feet, where it remains until it is 4 to 6 months old, depending on the size of the calf. Moving the calf and its pen, preferably uphill, once each week, takes the calf away from its contamination before too many of the oöcysts sporulate. The calves are not completely freed of infection, but they swallow enough oöcysts to get slight, nonclinical...

The main goal of current study was to investigate the prevalence of coccidiosis in broiler farms in Hamedan province, western Iran. Chicks and fecal samples were collected in all of the 220 broiler farms in this region. All viscera were examined for gross pathological changes. The mucosa of small intestine and the caeca were examined for the presence and identification of parasitic forms using ...

Bo\^NE COCCIDIOSIS is an infectious disease of cattle, known in its spectacular form as bloody scours or red diarrhea because of the characteristic bloody fecal discharges seen in severe cases. The disease is of economic importance in many parts of the world, including the United States {1, 12, 15).^ To the outright loss from fatal infections, which may take a heavy toll among calves, must be a...

The study objective was to evaluate the most commonly used strategies and practices in coccidiosis control in the Americas. Seventy five interviews with participants from Argentina, Brazil, Canada, Colombia, Mexico and Peru were carried out in the period March-April 2014. Nearly half of all broiler production in the region was represented. In respect to the number of rotations, 84% of the respo...

Coccidiosis is one of the major causes of kid mortality in tropical regions and causes significant loss to farmers by affecting growth and feed efficiency in the growing kid. The strategy to control the coccidiosis is mainly through drug usage and is not efficacious at present. Therefore, an alternative strategy is required to control the disease in goats. Increasing genetic resistance to cocci...

BACKGROUND The present study was intended to determine the prevalence and identification of species involved causing coccidiosis in broilers rearing under traditional farming system in Mirpur, Azad Kashmir, Pakistan. For the current study, a convenient sampling technique was carried out. A total of 7814 broilers (aged 1 to 6 weeks) were submitted to the Disease Diagnostic Laboratory of Livestoc...

A series of experiments were conducted to investigate the effect of starter diet protein levels on the performance of broilers vaccinated with a commercially available live oocyst coccidiosis vaccine before subsequent challenge with a mixed-species Eimeria challenge. Data indicated that an increasing protein concentration in the starter diet improved broiler performance during coccidiosis vacci...

Avian coccidiosis is one of the most important diseases of poultry and it is responsible for a large number of poultry mortalities worldwide. This study was carried out to investigate the occurrence and associated risk factors of avian coccidiosis in Osun State, Nigeria. Fecal samples were collected and examined from 5,544 avian species that were brought for treatment at the state veterinary ho...

Sir,?I read with interest the communication of Capt. Mukherji on ' The incidence of coccidiosis in the Arakans ' in 3'our December 1947 issue. I came across several (about a dozen) instances of isospora infection during routine stool examinations in army laboratories (1943-46). Most of these were ' routines' from the hospital patients (unselected), two detected during ' Food handler's carrier's...

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...
