ADJUSTING OF POULTRY BODY WHEN APPLYING COMPOUND ADDITIVES AND DIOLINK ANTIBIOTIC

The article explores the adaptation of poultry organism when applying sour-milk feeding additive of vitamin aminoacid complex and dolink antibiotic. The research found out that 4th group of poultry which received vitamin aminoacid complex had the highest body weight whereas 2nd group which received dolink antibiotic had the lowest body weight (10% less). The highest average daily growth was observed in 4th group which received vitamin aminoacid complex (Р<0.05–0.001). On poultry slaughtering the authors didn’t observe any pathological changes of organs. Slaughter yield of semi-eviscerated poultry was similar to 65.1; 65.5; 65.4 and 65.8% in the 1^st, 2^nd, 3^d and 4^th group respectively. The researchers analyzed the excrements of cecum and found out that the number of bifid bacteria in control group was increased from 10⁵ (aged 14 days) to 10⁶ КОЕ/sm³ (aged 42 days). The authors applied dolink antibiotic in the 2^nd control group and found out that the number of these microorganisms was reduced from 10⁶ (aged 14 days) to 10⁴ (aged 21 days); the number was 10⁶ КОЕ/sм³ for the poultry aged 42 days. The authors applied sour-milk feeding additive and found out that the number of bifid bacteria in the 3d control group was reduced from 10⁶ (aged 14 days) to 10⁵ (aged 21 days) that remained until the end of the experiment. The number of bifid bacteria in the 4th control group was reduced from 10⁶ (aged 21 days) to 10⁴ (aged 21 days); the number was 10⁶ КОЕ/sм³ for the poultry aged 42 days. When authors added sour-milk feeding additive or vitamin aminoacid combination, they found out that Bifidobacterium flora was faster developed (Р<0.05–0.001). The researchers analyzed the excrements of small intestine and found out that the number of bifid bacteria was reduced with advancing age: in control group it was reduced from 10⁷ to 10⁵ , in the 2nd and 3d groups it was reduced from 10⁶ to 10⁵ , and in the 4^th group – from 10⁵ to 10⁴ КОЕ/sм³ . The indicators of blood morphological composition and immune system of broilers outlined the positive effect of application of the additives investigated. The application of feeding additives based on probiotics and prebiotics for feeding broilers from their 1^st day and up to slaughter contributes to their productivity, physiological condition and low application of antibiotics or even eliminating of antibiotics
