Circadian blood variations and performance effects
in dairy cows fed during the day or the night

Effects of feeding pattern (day or night meals) on circadian blood changes and milk composition were studied in 4 dairy cows in a double Latin square design. Night meals reduced the speed of feed intake, inducing important endocrine-metabolic changes and reduced differences between fat and protein percentage of 2 consecutive milkings. The results have practical implications at the farm level and for blood analysis interpretation.
