| Summary: | The purpose of the research is to study economic damage caused by spontaneous eimeriosis in young turkeys.Materials and methods. On a turkey farm in the Moscow Region that had an adverse situation on eimeriosis in young turkeys, the infection spread among birds of different age groups, environmental contamination with eimeria oocysts, and species identification of eimeria oocysts parasitizing young turkeys were studied. The main types of economic damage were determined from spontaneous eimeriosis in young turkeys on this farm with setting necessary coefficients. Turkeys were considered to have died from eimeriosis when their carcasses had changes in the intestines typical to eimeriosis, and the number of oocysts in 1 g of intestinal contents was more than 20 thousand specimens. The damage from decreased productivity was determined based on the results of weighing spontaneously infected young turkeys versus the control birds free from the infection.Results and discussion. Based on the obtained data, the infection rates of eimeriosis among young female turkeys were determined to be 0.33, and 0.265 among males. The mortality rate among affected females was 0.2, and 0.18 among males. The damage from eimeriosis was RUB 728.8 per 1 dead bird in females, and RUB 1,399 in males. The damage from decreased productivity was RUB 161.3 per 1 bird in female turkeys infected with eimeriosis, and RUB 181.4 in males. |
