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.
Meat and bone meal (MBM) is a valuable source of protein, calcium and available phosphorus for broiler diets (Anwar et al., 2016). The use of MBM in broiler diets at levels above 50 g/kg minimizes the need for inclusion of inorganic P, thus reducing feed cost. Potential indigestibility of protein in MBM (Kim et al., 2012) may act as a predisposing factor for necrotic enteritis (NE). Increased production of nitrogenous bacterial metabolites including amines and ammonia in the hindgut may...

The use of Bacillus species as probiotic supplements is expanding rapidly and demonstrates immune stimulation, antimicrobial activities, enzyme production and competitive exclusion as the most prevalent modes of action. The objective of this study was to investigate the dosage influence on performance parameters of the novel probiotic strain CHCC15076 in birds recovering from necrotic enteritis (NE) caused by Clostridium perfringens. The experiment consisted of 1920 day of hatch Cobb...

1. Introduction Avian coccidiosis, caused by Eimeria spp., is one of the vulnerable enteric diseases and is endemic in vast areas of the tropical and subtropical regions [1]. It reduces growth performance affecting chicken meat production and accounts for about 30% of the total expenses on medications and other pharmacological products used to control poultry diseases [2]. Out of seven recognized species, E. acervulina, E. necatrix , and E. tenella cause...

1. Introduction Coccidiosis is a parasitic disease caused by an apicomplexan parasite of the genus Eimeria, which infects different parts of the intestinal tract depending on the species of Eimeria [1]. Eimeria spp. invade intestinal cells and cause physical damage to the intestinal epithelium, producing hemorrhagic diarrhea and disrupting the normal functioning of the intestinal tract [2]. This leads to impaired nutrient absorption and compromised gut health [3]. On the other hand,...
