The original proposal to North Kesteven District Council in Lincolnshire for 8,100 cows was withdrawn in April to tackle environmental concerns. The new plan is for 3,770 cows.
"Nocton's promoters have scaled down their plans but with a view to expanding them in the future. They still plan to cram the cows into massive sheds rather than graze them outdoors," said Friends of the Earth food campaigner Sandra Bell. "Instead of subsidising farming like this the government should be supporting planet-friendly farms that could create a thriving sector."
A Campaign to Protect Rural England spokesman said: "It could have serious consequences for the future of traditional dairy farmers and the countryside." David Barnes, one of the farmers behind the plan, responded: "We aim to demonstrate that the farm will cause little local impact and work well from an environmental and welfare perspective.
