Description

Results of investigations conducted from 1971 to 1973 have shown that the cattle in the mountainous regions of Czechoslovakia graze mainly from between 4.00 and 5.00 to between 9.00 and 10.00 a.m. and from between 5.00 and 8.00 to 9.00 p.m. On intensive pastures the dairy cows gave 25. 95 % of their time to grazing in the same place and 5.5 % to grazing in walk­ing. For this the young cattle needed 24.32 and 12.19 %, respectively. On extensive pastures the respective values were 16.1 and 15. 5 % for dairy cows and 19.56 and 23.74 % for young cattle. The longer periods of grazing on extensive pastures diminished the times of rest of the animals. This resulted in reduced animal ef­ficiency. Per 100 ha of extensive pasture the dairy cows produced 230.12 kg milk and the young cattle 20.49 kg live weight less than on the intensive pastures.
