1997
Harada, H. (Aichi-ken. Agricultural Research Center, Nagakute (Japan))
This survey was conducted twice (in 1992 and in the period from 1996 to 1997) to determine yearly changes of freestall housing and facilities on 38 dairy farms in Aichi Prefecture. The purpose was to determine the realities of freestall housing, pick up on the problems, suggest resolutions and extend modern dairy management. Housing structure, costs, the number of dairy cow, farm hands, and the structure of stall beds were surveyed. The results were as follows: 1) Dairy farms with freestall housing increased about by 3.8 farms each year and the scale of housing and milking parlors also increased in size. The average area of housing built after 1992 was 1,540 square meters and the average number of dairy cows per farm was about 100. The number of cow per farm will increase 23% in two years. The average employee per farm was about three, but, their numbers also will increase soon. Most farms used herringbone milking parlor (78%). 2) The structure of stall beds has changed to be more suitable and comfortable for the cows. However crowding of cows in their housing has increased year by year. 3) Half of the farm used sawdust as beddings, but some farms began to use dried manure or mattresses. 4) Most farms loaded manure with shovel-loaders or parnscrapers, and it was then heaped and fermented in a shed. Some farms dried manure in a greenhouse. 5) The average expenditure for housing and parlor per stall was about one million yen. Most farmers are deeply concerned about how to provide dairy housing or milking parlors, handle manure, and hire employees at low cost. If these problems could be solved, the scale of farms will grow bigger and bigger
