MD_DA751 DA MD DA751 Casein - National MADISON, WI. May 04, 2017 (REPORT 18) CASEIN - NATIONAL Rennet casein prices very slightly firmed. Acid casein prices are stable. Skim pricing is weighing on rennet casein, notwithstanding the significant increase in GDT Event 187 rennet casein pricing of 22.6% for the June contract. Some manufacturers note that the volumes involved with the last GDT event were relatively small, minor vis-…-vis the broader market, so not representative of overall market activity. Another factor in the GDT event, unlike the broader market, was strong participation by Asian buyers with motivation to buy this week. Acid casein markets continue to be significantly focused on contract fulfillment. SPOT SALES AND UP TO 3 MONTH CONTRACTS. PRICES ARE F.O.B., U.S. WAREHOUSE FOR EDIBLE NONRESTRICTED AND VARY ACCORDING TO MESH SIZE AND QUALITY. RENNET: 2.8000 - 3.0500 ACID: 3.5000 - 3.6500 1100CT eric.graf@ams.usda.gov USDA/AMS/Dairy Market News, Madison, Wisconsin Dairy Market News website: http://www.ams.usda.gov/market-news/dairy Dairy Market News database portal: http://www.marketnews.usda.gov/mnp/da-home
