7. Allow no strong-smelling material in the cow-house for any length of time. Store the manure under cover outside the cow-house, and remove it to a distance as often as practicable.
8. Whitewash the cow-house once or twice a year; use gypsum in the manure gutters daily.
9. Use no dry, dusty feed just previous to milking; if fodder is dusty, sprinkle it before it is fed.
10. Clean and thoroughly air the cow-house before milking; in hot weather sprinkle the floor.
11. Keep the cow-house and dairy room in good condition, and then insist that the dairy, factory or place where the milk goes be kept equally well.
The Cows
12. Have the herd examined at least twice a year by a skilled veterinarian.
13. Promptly remove from the herd any animal suspected of being in bad health, and reject her milk. Never add an animal to the herd until it is ascertained to be free from disease, especially tuberculosis.
14. Do not move cows faster than a comfortable walk while on the way to the place of milking or feeding.
