Bio laser system for milk farms is miniature, reliable, low-cost, electrically safe, low-power and eye -safe one which can be arranged as miniature low-voltage (<2V) elegant devices with both battery and standard electrical network power supply. Economy efficient lithium-ion battery supply sometimes is urgent for farms having high humidity especially in rainy periods and usual working conditions at farms also associated with waste of animals. Laser stimulation of milking efficiency and at the same time preventing the mastitis by mild exposure to laser radiation of certain, optimal wavelengths applied to specific biologically active zones of the udder of cows instead of treating ill cows with toxic antibiotics. The developed devices are proposed to be adapted for use every day continuously as part of standard milking process with automated milking machines.
