The article describes the research results on the complex enzyme and antibacterial drugs use in feed for the Hubbard cross broiler chickens. A studies review is presented, which showed that ergotropic preparations complex use when growing broiler chickens is poultry increasing the meat productivity effective method, as per basic zootechnical indicators. As a studying result an ergotropics complex combined use effectiveness in growing poultry, a significant decrease in a highly toxic elements number concentration in the broiler chickens carcasses and organs has been established, which is very important today. The preparation complex influence on the Hubbard cross broiler chickens meat chemical composition, physicochemical and tasting parameters was traced. Our research has proved the ergotropic drugs use effectiveness in broiler chickens, which is one of the increasing poultry meat productivity effective methods and the quality products necessary to provide the population needs with high nutritional and biological products values.
The article gives a comparative efficiency evaluation of anticoccidials of different pharmacological groups at experimental infection of chickens with field coccidia isolate selected from the production sites of the poultry complex of the Belgorod region. The selected mixture of field strains of coccidia is partially resistant to eimicide, maksiban, esdot, decox (anticoccidial index is from 150.0 to 156.3). High sensitivity was noted to robenz, avatek and tsigro (anticoccidial index is from 160.4 to 177.1), in the absence of birds’ death in all groups that receive preparations. The use of preparations against the background of chickens’ infection reduced the loss of body weight gain. In groups receiving eimicide, maksiban and esdot it reduced by 2.3 and 4%, respectively; in groups receiving decox, robenz, avatec and zigro it reduced by 5.7.11 and 15%. It should be taken into account that the partial resistance of coccidia to the preparations mentioned above can be increased and transmitted genetically. Therefore, there is a need for constant monitoring and rotation of preparations at this poultry complex.
This study presents research on ways and means of adapting international students to higher education in a Russian university. These international students are mostly from CIS countries (former Soviet republics). As a background, the article outlines the role and place of the Russian language in these countries. It goes on to describe how Samara (a large industrial city with 1,200,000 population, formerly Kuibyshev, in the valley of the Volga river) and its environment are presented to newcomers from Kazakhstan, Uzbekistan, Tajikistan, Turkmenistan, Kirgizstan and Armenia and analyzes the respondents’ answers to the questions in an online anonymous questionnaire that shows the degree of adaptation of foreign students to education in the Samara State University of Social Sciences and Education (SSUSSE). The paper gives an overview of the activities held at SSUSSE aimed at international students’ efficient integration into Russian everyday life and culture. The paper ends with some conclusions.
The sensitivity of the organism of broiler chickens artificially infested with a mixture of three types of eimeria to anti-eimeria drugs used in the Belgorod region was determined. For the experiment, synthetic coccidiostatics (decoquinate, maduramycin, nicarbazine, robenidin), ionophore antibiotics (lasalocid, monensin, narazine) and a complex phytobiotic “AdiCox AR” were taken. The smallest loss of live body weight of chickens was observed when feeding them in the diet of lasalocid, then decoquinate. Feeding the specialized feed additive “AdiCox AR” ensured the preservation of gains in live weight of chickens by 19.0% less than the most effective ionophore antibiotic lasalocid in our experiments. Then, in descending order, followed: narazine 10%, monensin 20%, nicarbazine 25%, maduramycin 1%, robenidin 6.6%. In connection with the obtained results, we consider it expedient to use lasalocid 15% at a dose of 500 g / t feed, decoquinate 6% at a dose of 500 g / t feed and AdiCox AR at a dose of 300 g / tons of feed. The use of narazine 10%, monensin 20%, nicarbazine 25%, maduramycin 1% should be carried out under constant monitoring of the sensitivity of the pathogen to the listed drugs. We consider the use of robinidin 6.6% inappropriate.
