Efficacy of vaccination and probiotic application against eimeriosis of chicken
Abstract
In this paper, the productive indicators of broiler chickens are given after a double vaccination with the feed method with a mixture of attenuated strains L-2-15 E. acervulina at a dose of 3000 oocysts / head, L-3-2 E. maxima at a dose of 500 oocysts/head and L-1-23 E. tenella at a dose of 1,000 oocysts/head with concurrent administration of a preparation based on yeast Saccharomyces cerevisiae type boulardii (I-1079) not less than 2 x 109 CFU/g. Chicken broilers were divided into groups: immune group, immune group with probiotic, control group of infection, control group of infection with probiotic, control native group and control native group with probiotic, 9 heads each. Twenty one days after the start of vaccination, the bird of immune groups and control groups was infected with a mixture field cultures of E. acervulina at a dose of 1,91 million oocysts/ head, E.maxima at a dose of 0,01 million oocysts/ head and E. tenella at a dose of 0,29 million oocysts/ head, isolated from the Russian poultry industry. The bird was observed for ten days after infection, taking into account the productive parameters of broiler chickens and the percentage of survival by groups. Statistically significant differences were obtained in the mean daily growth in the live weight of broiler chickens in control groups and control groups with a probiotic. Decrease in the average daily gain of live weight was observed in the groups of control infected and control infected with probiotic after infection with a mixture of field cultures of Eimeria. The survival rate in the control group is 88,9 %. In the immune group and the immune group with probiotic, broiler chickens were not observed to die.
