“…It cannot be excluded that plasma important ions such as Na + and K + may directly or indirectly influence Mel production. It is also known that melatonin can exert a feedback regulation on plasma cation levels as was suggested for chickens (Pablos et al ., 1995), or influence electrolyte levels in rat blood (Heidrich et al ., 2000). All these observations together provide a case for further study of a linkage between plasma electrolytes and Mel in fishes.…”

In freshwater (FW) rainbow trout Oncorhynchus mykiss of spontaneously low plasma calcium concentrations ([Ca2+]pl), plasma melatonin at night was significantly lower than that measured in FW fish with the highest [Ca2+]pl. In brackish water adapted rainbow trout with originally high [Ca2+]pl, plasma melatonin concentration at night was elevated. In cannulated flounder Platichthys flesus, night plasma melatonin increases (ΔMel) corresponded to [Ca2+]pl. It is postulated that in physiological steady‐state conditions, melatonin synthesis capacity is coupled to free calcium concentration in plasma of O. mykiss and P. flesus.

“…The elevated plasma Ca and Pi levels are associated with the improved eggshell strength [46]. The serum Ca exhibits a circadian rhythm which varied with the changed light: dark cycle in laying hens [50]. In the present study, the blood samples were obtained at the intermittent points of light-and dark-period, respectively.…”

Background: The absorption and transportation of calcium and phosphorus is mainly relied on their corresponding transporters. Eggshell is mainly formed during dark time in one egg cycle. The aim of this study was to determine the effect of different light regime on eggshell quality and the expression of the relevant calcium and phosphorus transporters in laying hens. Seventy two 56-week-old laying hens were randomly divided into two groups and subjected to the following treatments: 16 h light: 8 h dark (control) and 9 h light: 15 h dark (LDP). The expression of phosphorus transporters type IIb Na/Pi co-transporter NaPi-IIa (NPt2a) and NaPi-IIb (NPt2b), calcium transporter calbindin-D28k (CaBP-D28k), and plasma membrane Ca ATPase 1b (PMCA1b) were measured in small intestine, kidney, and eggshell gland. Results: The results showed that the feed intake (P < 0.001) and egg weight (P = 0.05) was decreased by LDP treatment, while laying rate, egg production, and feed efficiency were not significantly influenced (P > 0.05). Compared to control, eggshell hardness was increased (P < 0.05) by LDP treatment whereas eggshell thickness and eggshell percentage were not significant changed. Eggshell calcium (Ca) and phosphorus (P) contents were elevated in LDP-hens, compared to control birds. Compared to control birds, serum Ca (P < 0.01) and P levels (P = 0.079) at dark time were increased in LDP-hens while and alkaline phosphatase (ALP) activity was lowered (P < 0.05). The protein expression levels of CaBP-D28k and PMCA1b were not influenced in duodenum but were decreased at light time in jejunum of LDP hens. In kidney, the expression of CaBP-D28k, PMCA1b and NPt2a were not changed by LDP treatment. In eggshell gland, however, the expression of CaBP-D28k and osteopontin (OPN) were relative higher in LDP hens compared to control birds, whereas the PMCA1b expression was not altered. Conclusions: The result indicates that the increased circulating Ca and P concentrations in dark time are favorable for the deposition of calcium and phosphorus in eggshell. The result offers an alternative strategy for the laying hen with a worse eggshell problem.

“…However, if the calcium provided is higher in the morning and lower in the evening, these circadian genes become arrhythmic (Lin et al, 2018). In addition, serum calcium levels display a circadian rhythm (Sloan et al, 1974), which can be altered through photoperiod manipulations (Pablos et al, 1995). These findings suggest that varying photoperiods can mechanistically impact the timing of eggshell formation.…”

Circadian biology’s impact on human physical health and its role in disease development and progression is widely recognized. The forefront of circadian rhythm research now focuses on translational applications to clinical medicine, aiming to enhance disease diagnosis, prognosis, and treatment responses. However, the field of circadian medicine has predominantly concentrated on human healthcare, neglecting its potential for transformative applications in veterinary medicine, thereby overlooking opportunities to improve non-human animal health and welfare. This review consists of three main sections. The first section focuses on the translational potential of circadian medicine into current industry practices of agricultural animals, with a particular emphasis on horses, broiler chickens, and laying hens. The second section delves into the potential applications of circadian medicine in small animal veterinary care, primarily focusing on our companion animals, namely dogs and cats. The final section explores emerging frontiers in circadian medicine, encompassing aquaculture, veterinary hospital care, and non-human animal welfare and concludes with the integration of One Health principles. In summary, circadian medicine represents a highly promising field of medicine that holds the potential to significantly enhance the clinical care and overall health of all animals, extending its impact beyond human healthcare.
