U.S. cottonseed oil supplies for 1969/70 are estimated at about 1.9 billion pounds, a fifth more than last season. The increase is due mostly to the 1968/69 accumulation of CCC stocks. Domestic use of cottonseed oil declined steadily from 1.7 billion pounds in 1965/66 to a near-record low of 1.0 billion last season, with a sharp drop in its usage as a cooking and salad oil. Soybean oil has largely captured these markets; it is both substitutable and lower priced.
