Effect of light on dairy cattle in farm conditions – a review

Abstract

Abstract Cattle are among the animals with diurnal activity, which is due to the specific animal– environment relationship and the natural role wild cattle play in the ecosystem. As humans began domesticating, breeding these animals, they became an integral part of this relationship. This review article addresses the most important current issues: 1) a characterisation of contemporary knowledge on the biological determinants of the vision abilities of dairy cattle, 2) a discussion of the relationship between these abilities and animal health and performance, and 3) a characterisation of the light–animal relationship under husbandry conditions. The intricate link between the anatomical and physiological aspects of visual function in cattle and their circadian rhythms was emphasised. This connection directly influences cattle growth and development, as well as the health and performance of dairy cows during the long/short day photoperiods. The article also considers the possibility of managing dairy cows’ photoperiod and light quality to enhance their performance and overall well-being.
