Automation of artificial lighting design for dairy herd cows

Abstract

The article presents the results of experiments with the use of the developed energy-efficient LED-based lighting device for illuminating the horizontal working surface in livestock houses. The implementation of maintaining the magnitude and mode of illumination was carried out using programmable logic controllers. The results of the effect of the developed LED luminaire on the health and productivity of black-and-white dairy cows are given. The main indicators of the quality of milk in the control and experimental group after 30, 60 and 90 days were determined. It has been established that the use of the visible spectrum of artificial light emission with an adjustable amount of light does not adversely affect the cows’ organism, but rather stimulates its activity, which contributes to more abundant feed consumption and an increase in milk yield, and, accordingly, a reduction in production costs. The maintenance of the magnitude and mode of illumination using programmable logic controllers of the German company Schneider Electric has been implemented.
