Description
Grazing has traditionally been recognized as one of the most important labor-saving means in which herbage can be utilized more economically. However, in Japan, the practice of grazing is declining due to improved farm management - more animals per farm, greater harvest yield per area and higher production performance. Grazing animals tend to be healthier and more productive than animals kept in confinement. In addition, feed cost of raising dairy heifers on high pasture system is reduced by more than 50 % relative to the conventional (dry lot) system and to 65 % when the cost oflabor and facilities are considered (Miller and Amos, 1986). This experiment was conducted to compare the effect of grazing system with dry log system on nutritional intake and growth rate of dairy heifers.
