Circadian rhythms and diurnal patterns in the feed intake behaviour of growing-finishing pigs

Abstract: The feeding behaviour of growing-finishing pigs is an important indicator of performance, health and welfare, but this use is limited by its large, poorly-understood variation. We explored the variation in basal feed intake of individual pigs by detecting circadian rhythms, extracting features of diurnal patterns and assessing consistency over time, from day-to-day and across age. Hourly feed intake data of individual pigs (n = 110) was obtained during one growing-finishing phase, using electronic feeding stat… Show more

“…An FI circadian rhythm has been described for growing–finishing pigs together with an age dependence. Although social rank and individual pig preferences or personalities should be considered, pigs show a fasting period at night but progress from consistent feeding throughout the day to two characteristic ingestion peaks (close to dawn and dusk, at lower ambient temperature) [ 31 ].…”
