Clean dairies for safe milk
Cow dung and urine in dairy parlours and other buildings on a dairy farm have a negative effect on the health and safety of cows, dairy workers and the milk collected. For this reason, it is very important that these buildings are always kept clean.
Concrete floors should be scraped clean regularly, usually with a tractor with front or rear scraper, chain scrapers, manually or with a cable-drawn scraper blade. The manure is then either taken directly to the fields, where it is strewn, to a storage tank or sedimentation container, a treatment system or a manure dam.
The floors of alleys and holding areas should be slightly sloped from side to side so that they can be washed down with water under pressure without the dirty water then flowing back over an area that has already been washed down. Even when the floors are sloped correctly, better cleaning results are obtained by constructing the centre of the floor 25mm higher than the sides. The water will then flow from the centre of the floor to the kerbing, where most of the manure collects. However, this construction makes it more difficult to scrape the floors.
