Gazzavi L. Influence of geligeometeofactors and gumylyd on productivity and growth rhythm of goose different breeds.

On the base of complex hygiene, morphological and technological researches the influence of paratypic factors (such as air exchange, low temperatures, lightness, aero ionization and in-plant noises) on efficiency, immunodefence, humoral and cellular indexes of the natural resistance of the organisms of modern species of chickens and layer hens was studied. It saw found out that the extension of the air exchange provides optimal indoor microclimate, stimulates egg efficiency of layer hens, its organisms natural resistance and integrity. There was made sanitary hygienic estimation of breeding of the pullets which were bred in optimal temperature conditions and these which were bred in the housing without heating. The influence of the low temperatures (8-10 0С, 4-5 0С and 1,5-2 0С) on the laying ability, respiratory metabolism, bacterial and lysozyme activity in blood serum, protein and protein fractions content in blood was shown. The usage of negative air ions decreases the content of micro flora in poultry housing, stimulates growth of chickens and activates chicken's immunodefence. The light intensity of 60-40 lux for 1-7 day old chickens and light intensity of 10 lux for 34-40 day old chicken is the optimal light condition. Such light conditions provide the most intensive growth of poultry and higher immunodefence than the one that which is shown under existing conditions. It is reasonable to breed chickens on wire flooring, as such method helps to decrease the content of micro flora in the air, strengthen immunodefence, increase the poultry body weight and increase average daily population.
