METHOD FOR STIMULATION OF MAMMARY GLAND IN FIRST-CALF HEIFERS AT MACHINE MILKING AND DEVICE FOR METHOD EMBODIMENT

摘要

FIELD: agriculture, animal science, veterinary medicine. SUBSTANCE: one should affect teat's bottom with electric high-frequency unidirectional impulses at 10-200 Hz alternative frequency, 0-100 W amplitude modulated by low- frequency envelope at 0.01-2 Hz frequency. Device to implement the method has a pressure generator, generator of rectangular impulses, former of bell-shaped envelope, amplitude modulator, amplifier of rectangular impulses connected to an electrode upon a teat cup at teat rubber and designed as a disk with a hole of current-conducting rubber. Pressure generator is situated upon internal surface of teat chamber. High-frequency generator is switched for an output of the former of bell-shaped envelope and for an input of amplitude modulator. EFFECT: higher efficiency of stimulation. 2 cl, 2 dwg, 1 tbl
