Milk producers attached to cooperative societies supplying milk to Jaipur Dairy have threatened to stop their deliveries unless the public sector dairy reverses its decision to drastically reduce the payments by "arbitrarily' changing the solid non-fat (SNF) norms. The Rajasthan Dugdha Utpadak Sangh said here that Jaipur Dairy was paying an abysmal Rs.2 to 8 per litre to the cattle breeders for milk supplied by them, but had raised the milk prices for consumers thrice during the past two months. This has led to a loss of Rs.1.50 crore a month to the milk producers.
