METHOD FOR STIMULATING EGG-LAYING CAPACITY AND INCREASING FEED ASSIMILABILITY OF EGG BIRDS Russian patent published in 2001 - IPC

FIELD: commercial poultry farming. SUBSTANCE: method involves providing cyclic action upon birds in feeding and rest zones during daytime and night-to-day transition time, i. e. from dark time to light time and vice versa. During day time, birds are exposed to radiation in orange part of visible-light spectrum. Birds are stimulated for feed consumption before feeding phases by delivering acoustic tone messages combined with simulated dawns and twilights in the process of transition from dark to light time and vice versa by changing daylight factor in orange part of visible-light spectrum. Bird is stimulated for egg-laying by providing combined delivery of acoustic tone messages simulating egg laying calls and additional action upon birds of illumination in blue part of visible-light spectrum. During night time of day in dark period, air in poultry house is aeroionized by negative ions. Combined process mode of stimulating and synchronizing biological rhythms of feeding activity creates improved conditions for useful feed consumption. EFFECT: increased egg laying capacity and reduced power and material consumption. 2 cl, 1 dwg, 1 tbl
