On a recent visit to Drum Farm, Bonnybridge, Scotland I came across 2 interesting modes of ventilating the area around where the cattle feed.
Just above the ceramic feed troughs, there were 2 systems of ventilation.
I assume the idea is to allow the cows to have access to fresh air when they have their heads in the feed troughs and I dare say the draw of air to the outside may also assist in removing dust etc from the feedstuff itself.
Below – Photo below shows 2 curved ceramic ‘box channel’ type ventilators situated directly above the feed troughs.
Below – Photo below shows the opening of the ‘box channel’ type ventilator.
Below – Photo below shows the outside openings of the ‘box channel’ type ventilator. (These have been blocked up with bricks at some point to keep rats out.)
Below – 2 photos showing another type of byre ventilator – I call this the ‘mushroom’ ventilator! The section below would be situated within the byre and again directly above the feed troughs. This particular example has been removed at some point in the past.

All sections of both ventilators were salt glazed but no makers names were visible.
Below – This byre ventilator was found in a derelict byre near Dalquharran, Ayrshire. It was sitting within a broken stone wall.
