Description
The objective of this study was to clarify the effects of nursing frequency on the utilization of an automatic milk replacer feeding system (AMRFS) in Japanese Black calves. We designed two groups, the high nursing frequency group (0.5 l/time) and the low nursing frequency group (1.0 l/time). The frequency of human assistance to calves for visiting AMRFS in the high nursing frequency group using the AMRFS was significantly higher than that of the low nursing frequency group during the first day of using the system (P<0.05). After that, there were no differences between the groups. The frequency of attempts to gain a reward for calves in the high nursing frequency group was significantly higher than that of calves in the low nursing frequency group during the experimental period (P<0.05). The frequency of unrewarded visits to the AMRFS in the high nursing frequency group was significantly higher than that of the low nursing frequency group for the first 3 days and on the seventh day after introduction of calves (P<0.05). However, the likelihood of an unrewarded visit to the AMRFS at 49 days after introduction increased in the low nursing frequency group. The percentage of calves who consumed all of their allotted portion in the high nursing frequency group was significantly higher than that of the low nursing frequency group during the first four days after introduction (P<0.05). The body weight at weaning tended to be higher in the high nursing frequency group than in the low nursing frequency group. These results indicated that high nursing frequency is effective for artificial nursing by the AMRFS according to utilization of the AMRFS and calf growth performance.
