In recent years, livestock farmers per capita of working time and livestock workers have been increasing by the scale expansion. Under these circumstances, livestock farmers externalizing feed production has also been seen, and feed production contractors have increased nationally. Furthermore, operators with individually managed works at the contractor are present, expect in Hokkaido. In this study, we focused on the feed production contractor A in six contractors in Mamurogawa, Yamagata Prefecture, and clarified the relationship between contractor A and those who individually manage. Contractor A consists of Wagyu breeding farmer M and agricultural corporation G, which mainly produce rice, soybeans, vegetables and "pasture grass." Contractor A has been consigned as "rice straw harvesting." "manure spreading" and "pasture grass harvesting" from farmer M, corporation G and two villages. Among these works, most of the trustee area is that of corporation G. Farmer M and corporation G, are consignors only of pasture grass : pasture grass produced by corporation G, and harvested by contractor A, are sold to public ranches : Akiyama ranches. Moreover, the harvested rice straw is sold to both farmer M and Akiyama ranches. Farmer M expanded the Wagyu breeding scale in one year when contractor A started consignment of rice straw harvesting. In the case of farmer M, rice straw from corporation G accounted 52% of the total amount of roughage it feeds. Also, corporation G gained sales from pasture and rice straw, which accounted for 20% of all its sales. This means that the products are very important income sources for corporation G.
