Coccidiosis in poultry
Coccidiosis is a protozoal disease causing diarrhea, ,weight loss and decreased production in poultry. It can be fatal. Prevention is key and is achieved with use of anticoccidials or vaccination. Diagnosis is by fecal flotation to detect oocysts, often in combination with characteristic necropsy findings. Coccidiosis is caused by protozoa of the phylum Apicomplexa, family Eimeriidae. Most species affecting poultry belong to the genus Eimeria and infect various intestinal sites. The disease course is rapid (4–7 days) and is characterized by parasite replication in host cells with extensive damage to intestinal mucosa. Coccidia in poultry are generally host-specific, and the different species infect specific portions of the intestine. However, in game birds, including quail, the coccidia may infect the entire intestinal tract. In poultry, game birds reared in captivity, and wild birds, coccidiosis occurs worldwide.
A key factor in the biological performance and efficiency of food producing animals is the health of the gastrointestinal (GI) tract. A healthy GI tract ensures optimal digestion and absorption of nutrients. Within the poultry industry there are many initiatives aiming to understand gut health and how it can be influenced to improve efficiency and reduce disease. These initiatives have shown that there is a need for further characterisation of...

Magni-Phi (Phibro Animal Health) is a triterpenoid saponin feed additive that has been shown to exert anticoccidial effects in broilers. A series of four floor pen studies was carried out to evaluate the efficacy and performance responses of Magni-Phi (MP) when used in combination with a standard coccidiosis vaccination program. Trials 1 and 2 were designed to assess the effects of MP (0 and 250 ppm) in birds receiving CocciVac at hatching. Trial 3 was designed to determine the ideal...

INTRODUCTION
Commercial poultry farming is expanding day by day and contributing in the provision of affordable and high quality proteins (Ahmad et al., 2010; Ghafoor et al., 2010). However, this sector is still confronted with many enteric diseases like coccidiosis which are hindering its progress (Saima et al., 2010; Hafez, 2011).

It's not mother's milk, but egg yolk may be the closest remedy for boosting the immune system of newly hatched chickens against infectious diseases such as coccidiosis.
A major disease of chickens, coccidiosis is caused by intestinal parasites—single-celled protozoans in the genus Eimeria. Disease-affected birds are unable to absorb feed or gain weight, costing the poultry industry more than $600 million annually in the United States and $3...

Introduction Coccidiosis is a realistic problem and one of the most important diseases of poultry worldwide. It is caused by a protozoan parasite known as Eimeria that invade the cells of the poultry intestine. Species of coccidia which commonly affect poultry are Eimeria tenella, E. acervulina, E. necatrix, E. maxima and...

Abstract Background : Avian coccidiosis is a major parasitic disease of poultry, causing severe economical loss to poultry production by affecting growth and feed efficiency of infected birds. Current control strategies using mainly drugs and more recently vaccination are showing drawbacks and alternative strategies are needed. Using genetic resistance that would limit the negative and very costly...

Anticoccidial efficacy of ‘Coxynil” a herbal feed additive was tested against Einieria tenella in broilers, vs. a vs. Salinomycin. Body weight of birds challenged with E. tenella in Coxynil treated groups was higher as compared to Coxynil untreated & Salinomycin treated groups.. Oocyst out put, lesion score, HI titres against New Castle disease virus and T Cells were significantly higher in Coxynil supplemented groups. Examination of ceaca of the birds, revealed that the...

Coccidia are single-celled intestinal parasites that currently represent one of the greatest challenges to the broiler industry. To keep the level of infection low, farmers commonly add coccidia-inhibiting chemicals (coccidiostats) to broiler feed. While this does not kill the parasites, it greatly reduces the incidence of overt sickness and death from infection. While clinical coccidiosis is therefore not a problem, veterinary authorities have never been able to gauge the extent of subclinical...

Each year, U.S. poultry producers raise about 7 billion broilers. They use a combination of antibiotics and vaccines to protect these birds from infectious diseases. Antibiotics are critical to ongoing efforts to fight off diseases and infections; they have been able to kill or stop growth of many different kinds of protozoa and parasites as well as bacteria. One major disease of chickens—coccidiosis—is named after intestinal parasites collectively referred to as coccidia, which are...

In a recent survey, it was estimated that the cost of subclinical necrotic enteritis was as high as $0.05 per bird (Van der Sluis, 2000). Using these estimates and 1999 estimates on world broiler meat production, the cost of necrotic enteritis to the poultry industry globally is nearly $2 billion (Anonymous, 2000). Both clinical and subclinical necrotic enteritis is common in all poultry growing areas of the world (Van der Sluis, 2000). The disease was first described by Parish (1961) and...
