“In my opinion, the introduction of Equilume’s blue wavelength lighting to breeding mares constitutes the biggest technological step forward for equine reproduction since the ultrasound machine became widely used for scanning in the 1980s.
I first started using the Equilume masks in New Zealand when they came out in 2014, which suited the farming system there. For UK breeding farm practice, I find the Equilume Stable Light system to be superior. The benefits are comprehensive: the circadian effect on dry mares seems more profound than when using fluorescent lights, in that medical intervention is needed less frequently to stimulate cyclicity; birthweights are higher, particularly in early season mares; those mares that consistently go longer in gestating are (as a group, on average) shortened up.
The difference in electricity consumption alone justifies their purchase from economic and environmental perspectives. Beyond all these considerations, I think the evidence that microbial decay is caused by blue light wavelengths is interesting. I have noticed fewer neonatal infection issues since their introduction, particularly diarrhoea, presumably due to the lower microbial load in the stable environment.
Really, from every perspective as a vet and a breeder, these lights tick the box.”
