APPLICATION OF PROPOLIS TINCTURE TO PREVENT INFECTIONS OF BROILERS

Abstract

Scientific and industrial experiment was carried out at the poultry farming on Ross308 broilers. The authors explored various schemes of application of propolis tincture for pre venting respiratory infection of poultry of bacterial etiology. The researchers arranged a control group and two experimental groups according to the principle of analogues. The groups were placed in separate isolated poultry houses. Chickens of the control group were fed with antibiotic Tilmipool (0.3 ml/l of water) aged 1-3; 14-16; 25-27 days; their poultry house was sprayed with Ecocide C (0.5%, 1 l/100 m3, exposure 60 min) on 1, 7, 14, 21-22, 28-29, 35-36 days of their life. In the 1st group the antibiotic was applied as it was in the control group; aerosol treatment was conducted with propolis tincture (dilution 1:20, 0.5 l/100 m3, exposure 60 min) during the same age periods. In the 2nd group, propolis tincture (1 ml/l of water) was applied for broilers aged 1-5; 14-18; 25-30 days combined with aerosol treatment of propolis tincture air (dilution 1:20, 0.5 l/ 100 m3, exposure 60 min) for 1, 7, 14, 21-22, 28-29, 35-36 days of their life. The most effective way to prevent respiratory diseases of poultry is seen in application of propolis tincture according to the scheme used in the experiment with the 2nd group. The scheme reduces the number of pathogenic, relatively pathogenic microorganisms in the scrapes from the laryngeal mucous membrane and in the air of the poultry house, activates the immune system and metabolism of poultry, increases livability on 3.0% and live weight on 342.7 g, which eliminates application of antibiotics for preventive measures, providing environmentally safe products of poultry farming.
