A Useful Cow=shed Disinfectant

The objection to most of the disinfectants one seesi in cowsheds is the fact that they are very liable to taint the milk if used extensively. When udder and teat troubles are prevalent the farmer is often puzzled as to what disinfectant to use, but the following formula provides a solution that is cheap, effective and does not give rise to any milk taint : lib chlorinated lime (Calx chlorinata), 41bs washing soda (soda carbonate crystals), 1 gallon of watqr. Dissolve the soda in a gallon of hot water and allow to become cold. Stir in the chlorinated lime, add 6oz. common salt, and agitate at intervals for an hour. Cover and let the mixture settle. Bottle the clear fluid, cork, and keep in the dark, as light causes the hypochlorite solution to alter its composition. Use half-pint of this stock solution to, say, 4 gallons of cold water for washing teats, dipping teat cups after milking each cow, etc. There are several proprietory lines of this nature on the market, but this fluid can be prepared at a much cheaper rate, and is equally effective. If dairy factories would purchase chlorinated lime in bulk for issue to suppliers the cost would be reduced by at least half. The only objection to this disinfectant is that it is unstable and needs to be freshly made about once a week. The addition of the common salt helps to make the solution more stable.—T.. H.
