MAIN FACTORS AFFECTING INFLUENCE ON PRODUCTIVE AND BIOLOGICAL INDICATORS OF EVE FLOCK GEESE
Now the scientific research dealing with live organisms in biology and agriculture has no complex, generalizing character. Researches to definite influence extent of various factors on productive and biological indicators are executed in the conditions of the Kurgan region, on eve flock geese. Fodder factor rendered the highest influence extent on efficiency and reproductive qualities. It settled down in average range (23.67%, at P≤0.01 and 35.42%, at P≤0.001) while influence extent of egg-laying season, breed and age had considerable dispersion from 0.10 to 71.01% (P≤0,001) that indicates instability of influence of these factors. Two factors rendered the highest influence extent on incubatory egg quality: breed and feeding, where influence extent settled down in average range (21.94-49.13% and 21.35-49.90% respectively). Such factors as egg-laying season, geese age and fodder factor influenced as much as possible on the physiological condition of eve flock geese. Conclusions have been drawn on the basis of researches. We defined that the average and high range of influence extent in various groups of indicators is revealed for a fodder factor when studying influence extent of major factors: egg-laying season, breed, age, egg-laying period, feeding - on productive and biological indicators of eve flock geese. Such factor as breed also influenced on incubatory egg quality; egg-laying season and eve flock geese - on physiological state. We consider necessary to exclude such indicators as egg Haw's unit, shell thickness, egg volume and leukocytes quantity from groups of estimated indicators by influence extent of the studied factors because these indicators considerably go beyond averages for the estimated groups of ranges indicators.
