Applications have been submitted for the units, each housing up to 950 pigs, to be built on Holme Hill Farm in South Kelsey.

Jenny Stimson, clerk of South Kelsey Parish Council, said she had concerns about the smell, and traffic generated by the pig units.

The applicant, Frank Tobin, declined to comment on the matter.

Ms Stimson said: "We have to look at all sides of this and look at what impact it is going to have on the village.

"We have to wait until it goes to planning to see what is going to be done with the slurry because the smell is dreadful.

"Our road system is terrible and, with the amount of traffic that's going to be coming through, it's going to cause the roads to be even worse."

But BBC Lincolnshire's farming correspondent, Alan Stennett, said modern pig units had tight restrictions.

"The smell of the actual unit is virtually nil. The slurry spreading is where you get the problem and if you're dribbling it on [as it suggests in the report], you limit the amount of smell.

"If someone wants to put in a pig unit now, you would be talking about 1,000 pigs as standard."

West Lindsey District Planners will meet on Wednesday evening to discuss the plans.
