At first the suckling behavior at 30 days after birth was observed for 24 hours (Table 1). The foals sucked the breasts of their mares night and day relatively regularly. The suckling behavior at 5, 10, 30, 60 and 90 days after birth were then observed for 12 hours. The mean suckling frequency was 2.3 times/hr (Table 2) and the mean suckling time was 57.6 seconds/hr (Table 4). The suckling time did not vary with age (Table 3). The suckling frequency was slightly reduced from 5 days (3.6 times/hr) until 30 days (2.3 times/hr) but did not change thereafter (Table 2)., Article, 信州大学農学部紀要 23(2): 57-64(1986)}, pages = {57--64}, title = {木曾馬の吸乳行動について}, volume = {23}, year = {1986} }
