This study describes the instruments used in recording the feeding patterns of 21 pigs of three different breeds fed ad libitum from weaning to adulthood. The feeding behavior of the pigs was characterized by 1) the presence of well individualized meals, and 2) the circadian distribution of food intake: whatever the breed, the animals preferred to eat in the daytime. This diurnal character of food intake was accentuated gradually with age. The frequency of the daily food intake decreased progressively from a mean of 9.5 meals after weaning to usually 3 at adulthood when growth was finished (2 meals in the daytime and 1 at night).
本研究描述了用于记录21头三种不同品种猪从断奶到成年自由采食时采食模式的仪器。猪的采食行为特点为：1）存在个体差异明显的餐次；2）食物摄入量的昼夜分布：无论品种如何，动物都更喜欢在白天进食。随着年龄增长，这种食物摄入的昼夜特征逐渐增强。每日食物摄入频率从断奶后的平均9.5餐逐渐减少，到成年生长结束时通常为3餐（白天2餐，晚上1餐）。
