Disruption to milk collections is set to continue over the weekend as sub-zero conditions show no sign of easing.
Over the past 24 hours, icy conditions caused by freezing temperatures and compacted snow on side roads and farm roads have caused widespread disruption to milk collection patterns, said First Milk.
Milk Link reported adverse conditions had resulted in delays or cancellations to collections, with a relatively small number of suppliers being advised to dispose of milk.
And with yet more snow forecast, there is no sign of the situation improving over the coming days.
"As a matter of urgency we are liaising with our hauliers on how disruption can be kept to an absolute minimum," said Milk Link's Will Sanderson.
Wiseman admitted that tough conditions had meant fulfilling obligations had been a constant battle.
But with milk suppliers based as far north as Aberdeen and processing units as far south as Bridgwater, the company reported minimal losses.
Although extreme weather may be relatively new in the south, Scotland had been contending with sub-zero conditions for some time, said Wiseman's Graeme Jack.
"We have seen temperatures as low as -19C at times, but we are just getting on with it," he said.
"We have done everything in our power not to let farmers down. Over the past 10 days we have only lost a few thousand litres of milk, which is negligible considering we process and distribute about 1.6-1.7 billion litres a year."
And these minimal losses had been a result of a Herculean effort from the company's drivers and good partnership with farmers, he said.
"Producers may have experienced delays in milk collection, but we will continue to do our best to get our tankers on to farms."
Muller, which collects milk from farmers in Shropshire and Cheshire, also reported no major problems with milk collection. "We have put spurs on the vehicles and moved the majority of collections to daylight hours to make collection easier."
Milk Link advised farmers to keep in close contact with the company and hauliers, to find how the weather might affect collections, via the processor's Linkline service and website.
Other processors have advised farmers to insure their milk so they can claim compensation if collections cannot be made.
Rural insurer NFU Mutual said three-quarters of the UK's dairy farmers had neglected to insure their milk.
A company spokesman said producers would be expected to have extra capacity to store milk until their next collection day, but after that claims could be made.
