The purpose of this paper is to analysis about Effect and Problem of Dairy Farming under the Mixing-Automatic Feeding System with Silo-crane in managerial. The method of evaluation is questionnaire and investigation. There are 3 type on the Mixing-Automatic Feeding System with Silo-crane. "S1-type" is that Dairy farmer uses only Silo-crane. "S2-type" is that Dairy farmer uses Silo-crane and Mixer. "S3-type" is that Dairy farmer uses Silo-crane, Mixer and Feeder. Especially we call "S3-type(Auto)" that Dairy farmer uses Automatic Feeder which is made of National Grassland Research Institute. Farmer evaluated S3-type best of all the type. Because S3-type Feeder has an effect of labor reduction, increasing milk quantity, and S3-type has the best effect of all the type. A problem of this system is a technical problem, maintenance, economical problem and etc. S3-type(Auto) on Silo-crane make 0 of feeding working hours. This system gives time and mind to spare to dairy farm management. Many farmer who use S1-type prefer S3-type to S2-type although they need the largest cost to introduce S3-type of all the type. Because S3-type brings the most labor reduction and has fewer cost and fewer times to prepare than S2-type. It is advisable that farmer introduces S3-type without going through S2-type.
