The present study was designed to compare the effect of coccidiostate drugs and cocccidial vaccines on performance of coccidian-infected broiler chickens. Nine hundred and sixty one-day-old broiler chicks from the Ross strain were randomly divided to eight treatment groups that each group contained 3 replicates. The birds of group 1 as negative control and group 2 as positive control did not re...

coccidiosis is one of the most important disease in poultry. since using of anti-coccidial drugs or vaccination are considered as the most common preventive measures of this disease, an experiment was conducted to compare effectiveness of these methods. nine hundred and sixty day-old male ross broiler chicks were randomly assigned to eight treatments and fed with a corn-soybean meal basal diet ...

background: despite the use of prophylactic chemotherapy and vaccination, coccidiosis is still one of the most devastating diseases in poultry industry. understanding the immune mechanism helps researchers to prevent this parasitic infection more effectively. objectives: the purpose of this study was to evaluate the antibody response in chickens, induced by a live attenuated vaccine (livacox q)...

This experiment was conducted to study the effects of whole yeast (Pichia guilliermondii; CitriStim, ADM, Quincy, IL) cell product supplementation on cecal microflora population and intestinal immune parameters in broilers. In the first experiment, birds were fed 0, 0.1, or 0.2% yeast cell wall product for 42 d. Feeding yeast cell wall products decreased (P = 0.03) the proportion of Escherichia...

In each of two experiments with young, feed-restricted broiler breeder pullets, the effects of differences in dietary protein intake on intestinal development and growth were studied. All pullets were restrict-fed either a 15 or 19% CP diet to see whether differences in dietary protein would influence intestinal growth in the face of controlled exposure to coccidiosis. In each experiment, pulle...

The study was aimed at detecting the effects of Baycox and Chitosan on the development of coccidiosis on a broiler farm. The study involved 80 six-week-old-broiler chickens divided into two equal groups. Each group was divided into four subgroups: control (I); Baycox-treated (II); Chitosan treated (III); and Baycoxand Chitosan-treated (IV). Baycox was applied for 2 d in a concentration of 25 pp...

conclusions the results of this meta-analysis showed that gardasil and cervarix vaccines are highly effective against cervical cancer. according to the point that approximately 50% of cervical cancers and human carcinogenicity are related to hpv-16 infection, the bivalent hpv vaccine might have protective effects against hpv-16 cin2-3 lesion and cervical cancer. results by combining the results...

This experiment studied the effects of whole yeast cell product supplementation on broiler production parameters, fecal coccidial oocyst counts, and local and systemic immune parameters following an experimental coccidial infection. Birds were fed 0, 0.1, or 0.2% whole yeast cell product (CitriStim). At 21 d of age, birds were challenged with live coccidial oocysts. Supplementation with whole y...
