BACKGROUND There is an ongoing debate on how ECG interpretation should be taught during undergraduate medical training. This study addressed the impact of teaching format, examination consequences and student motivation on skills retention. METHODS A total of 493 fourth-year medical students participated in a six-group, partially randomised trial. Students received three levels of teaching in...

The importance of testing the use natural adaptogenic preparations in local poultry farming breeding broiler chickens is aimed at maximizing productive potential work and increasing survival rate chickens. From first day to age seven weeks, effects succinic citric acid on growth live weight, waste were experimentally tested four groups. results confirmed positive effect these drugs important ec...

We used mark-recapture methods to estimate age-specific apparent survival rates for male Lesser Prairie-Chickens (Tympanuchus pallidicinctus), a gamebird of conservation concern. A total of 311 male prairie-chickens (135 yearlings, 176 adults) were captured and banded during a 5-year study in southwest Kansas. Time-since-marking models were used to estimate apparent survival after first capture...

The article presents the evaluation of curative and preventive efficacy anticoccidial drug “Coccimax” in a joint application feed additive “Mintov”, experimental eimeriosis chickens. Were determined degree infection dynamics changes body weight bird. It was found that use anticoccidium together with “Mintov” helps to reduce infestation chickens (at end experiment, birds control group higher by ...

this study was conducted to assay the use of saturejahortensis l. (savory) essential oil in the drinking water on broiler production and blood glucose, uric acid, creatinin and cholesterol. four hundred and twenty day old broiler chickens (ross 308) was used in a completely randomized design with 6 treatments and 5 replicate. experimental treatments included: 1) control, 2) tween (a solvent for...

Toxoplasma gondii is a protozoan parasite with a broad range of intermediate hosts. Chickens as important food-producing animals can also serve as intermediate hosts. To date, experimental studies on the pathogenicity of T. gondii in broiler chickens were rarely reported. The objective of the present study was to compare the pathogenicity of 5 different T. gondii strains (RH, CN, JS, CAT2, and ...

to survive in natural waters, bacteria must respond to variety of environmental factors. flexibacter survival in the aquatic environment is influenced by number of parameters, such as temperature, heavy metal concentration and oxidation. here we investigate the influence of these factors on the survival of flexibacter chinensis in starvation medium. our data shows that different concentrations ...

A study was carried out to investigate nitrogen metabolism in response to cecal ligation and colostomy in chickens. We used colostomized plus ceca-ligated chickens fed a low protein diet or a low protein diet supplemented with urea. When both types of diets were fed, nitrogen balance and utilization tended to increase by cecal ligation while total nitrogen excretion tended to decrease. Colostom...

Radiotelemetry has provided wildlife biologists with a tool to estimate survival where fates of individuals likely are known. Analyses of known-fate data can yield accurate survival estimates if 5 assumptions are met. Two of these assumptions are rarely tested: that transmitters have no effect on survival of study animals and that right-censoring (i.e., any animal not located is as likely to be...
