“…It is crucial to note that continuous working lighting does not increase milk production, and it leads to high costs (ASAE, 2005). There is no advantage to extensive artificial lighting given its price, cow welfare implications, and the preservation of the natural diurnal variation in milk fat composition (Asher et al, 2022).…”

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.

Bioactive Peptides in Dairy Milk: Highlighting the Role of Melatonin

Melatonin, an endogenous indolamine derived from tryptophan, is primarily synthesized by the pineal gland in mammals and regulated by a complex neural system. Its release follows a circadian rhythm, which is crucial for regulating physiological processes in response to light–dark cycles in both humans and animals. In this review, we report that the presence of this hormone in bovine milk, with significant differences in concentration between daytime and nighttime milking, has increased interest in milk as a natural source of bioactive molecules. Melatonin lowers cortisol levels at night, reduces body temperature and blood pressure, coinciding with decreased alertness and performance, acts as an antioxidant and anti-inflammatory agent, modulates the immune system, offers neuroprotective benefits, and supports gastrointestinal health by scavenging free radicals and reducing oxidative stress in dairy cows. Many factors influence the release of melatonin, such as the intensity of artificial lighting during nighttime milking, the frequency of milkings, milk yield, and genetic differences between animals. Nocturnal milking under low-intensity light boosts melatonin, potentially reducing oxidative damage and mastitis risk. Additionally, ultra-high temperature (UHT) treatment does not significantly affect the melatonin content in milk. However, further research on its stability during milk processing and storage is crucial for ensuring product efficacy. In some countries, nighttime milk with naturally elevated melatonin content is already commercialized as a natural aid for sleep. Thus, naturally melatonin-rich milk may be a promising alternative to synthetic supplements for promoting better sleep and overall well-being.
