The present work was performed to study the effect of vaccination with Cocci Vac B on cellular and humoral immunity of chickens. The study comprised 70 chicks hatched from hens none vaccinated against coccidiosis. The chicks were subdivided into 4 groups. The 1st group comprised 25 chicks, kept as apparently healthy control, the 2nd group consists of 10 chicks, infected with 10000 mixed sporula...

The medicinal plants and herbs have been used for many years in the treatment of various diseases in animals and human beings. Now-a-days, utilization of these medicinal plants is increasing. These are used in animal feed as the growth promoters. Due to prohibition of most of the antimicrobial growth promoters in animal feed because of their residual effects, plant extracts are becoming more po...

Large-scale screening has led to the identification of several experimental compounds that have very potent intrinsic activity against coccidia, but the lack of translation to in vivo efficacy has been a major hurdle in developing such leads into effective new drugs. We developed methods to explore the impact of oral availability and appropriate distribution in tissue, both of which are potenti...

Anticoccidial effects of green tea (GT)-based diets were evaluated in chickens following oral infection with Eimeria maxima an ubiquitous intestinal parasite of poultry that impairs the growth and feed efficiency of infected birds. Five-week-old chickens were assigned to four groups (GT 0.5%, GT 2.0%, untreated/infected and non-infected control) and each group consisted of 15 chickens. Chickens...

post inoculation. Across all isolates there was a linear improvement in performance and decrease in coccidiosis lesions. Within all categories there were not significant differences between the NMI and N125 except for E. acervulina lesion scores (NMI 0.0 and N125 0.4). All other treatments and categories were significantly different. Feed conversions were NMU 1.447, NMI 2.594, N36 1.956, N72 1....

In the course of our studies concerning the derivatization of the polyether ionophore nigericin1'2) we observed a dependence of the antibacterial activity on the counter ion at C-l,3) which prompted us to investigate if related effects can also be found for other polyethers and indications. Salinomycin (1), for example is another important polyether4'5) which is produced in combination with rel...

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...
