内容記述(抄録等)
The grazing behaviors of Japanese Black Cattle (Wagyu) which is pastured on woodland were studied between nursing and not nursing under constant observation for 24 hours in June 3 to 6, 1964.
The results obtained are summarized as follows :
1. Grazing time on woodland per head for 24 hours was from 611 to 615 minutes and there was no great difference between nursing group and not nursing one.
2. Ruminating time on woodland for 24 hours was 396 minutes on the average per head in nursing group, 366 minutes in not nursing one respectively. The percentage of ruminating time at night was longer than that in day time in both groups.
3. Resting time on woodland for 24 hours was 322 minutes on the average per head in nursing group, 386 minutes in not nursing one respectively. The ration of resting time at night was longer than that in day time in nursing group, while it was longer at day time than that in night time in not nursing one.
4. The total time spent in migrating and loafing on woodland tor 24 hours was 112 minutes on the average per head in nursing group, 74 minutes in not nursing one respectively, and the difference in both groups was due to the amount of loafing time.
5. The frequency of defecation and urination per head for 24 hours in nursing group was greater than that in not nursing one, and the frequency of drinking per head per day was from 2.3 times in both groups.
6. The distance walked by cattle on woodland per head for 24 hours was averaged 5.3 km in nursing group and 4.2 km in not noursing one.
7. The topographical distribution of several behaviors on woodland was the greatest in open slope and was the smallest in valley in both groups.
