Abstract

One of the problems in industrial poultry farming is to provide high resistance to disease. Today in Ukraine widely used vaccination of poultry against a major viral diseases - infectious Infestiosus bursae disease of chickens. In this connection the application of probiotic remedies to enhance immunological reactivity in poultry is actual.

The aim of the research was to clarify the influence of the drug BPS- 44 and different amounts of yeast Saccharomyces cerevisiae on the strain of post-vaccination immunity against Infestiosus bursae disease in broiler chickens. The experiments were performed on broiler-308 inthe farm "Fedyuk M" Zolochiv district, Lviv region. Keeping of chickens were cage with free access to food and water. Technological parameters of broiler (temperature and light conditions) were in compliance with ONTP 2005. The experiment was carried out on 4 groups of broiler chickens,100 ineach scheme: control group fed a standard diet (SD) under the existing rules, recommended for cross ROSS - 308; 1 research group in addition to the SD received probiotic BPS-44 (registration certificate number 2154-04-0254-06 from 24.11.2006 g.), Made on the basis of the production strain of bacteria Bacillus subtilis ssp. subtilis 44-p, a dose of0.21 g/ kg treatment group 2 - 1% yeast Saccharomyces cerevisiae; 3 research group chickens - 2% yeast Saccharomyces cerevisiae (Table 1). The 15-day age chickens administrated vaccine against the disease.

For the immunological studies in chickens took blood at different ages: 11-, 27-, 34- and 41-day age. Definition of specific antibodies was performed by ELISA using test systems company Biochek.

The stimulating effect of the drug BPS-44 and Saccharomyces cerevisiae yeast in the composition of feed for broiler chickens on the strength of post-vaccination immunity against Infestiosus bursae disease has been established. This use of Saccharomyces cerevisiae yeast feed consisting largely influence the induction of specific immunity to the virus of Infestiosus bursae disease than drug BPS-44.
