No. 6. DEPARTMENT OF AGRICULTURB. 1*7 



MILK HYGIENE 



(1) The producer should agree to permit the inspector to examine 

 his herd and premises as often as it may be considered necessary, 

 and give said inspector such information as may be desired as to 

 the herd, the food, and the method of handling the milk, etc. 



(2) The room in which cows are kept and milked must be reserved 

 for the exclusive use of the cows. Straw, hay, and other foods, wagons, 

 stable tools and the like, should not be stored therein. 



All livestock other than cows, such as dogs, cats, poultry, etc., 

 must be excluded from the stable in which the milch cows are kept, 

 and an effort should be made to eliminate rats and other vermin. 

 (Calves and bulls may be allowed in the same room, if kept clean 

 and sanitary.) 



(3) The cow stable shall be provided with adequate ventilation, 

 either through the medium of air chutes extending from the room in 

 which the cows are kept to the outside air, or by the substitution of 

 muslin for glass in the window openings. At least 600 cubic feet of 

 air space must be provided for each cow. 



(4) Enough windows must be installed for the satisfactory lighting 

 of the stable (2 square feet of window light to each 600 cubic feet 

 of air space to represent the minimum) and the glass in such windows 

 must be kept free from dust and dirt. 



(5) Stable floors must be water tight; they must be properly 

 graded and well drained; and must be made of some non-absorbent 

 material, such as cement, since such floors can be more easily kept 

 clean than floors made of wood or earth, 



(6) Manure gutters should be provided, and they should be from 

 6 to 8 inches deep, and constructed of non-absorbent material. 



(7) The platform on which the cows stand must be made of some 

 non-absorbent material, and so constructed that manure and urine 

 will drop into the gutter, and it must be well lighted and kept clean 

 at all times. 



(8) The ceilings and walls must be so constructed as to be easily 

 cleaned. If the space above the cows is used for storage, the ceiling 

 must be made tight so as to prevent chaff and dust from falling 

 through. The ceilings, walls and ledges must be thoroughly swept 

 down and kept free from dust, dirt, manure or cobwebs. They must 

 be whitewashed at least twice each year unless the walls are painted 

 or made of smooth cement. 



(9) If individual drinking basins are used, they should be drained 

 and cleaned at least twice each week. 



(10) Feed boxes, mangers and feeding floors shall be kept in a 

 clean and sanitary condition. 



(11) There should be no direct opening from the silo or grain pit 

 into the room in which the cows are milked. 



(12) In order to protect the atmosphere from dust, dry fodder 

 should not be fed to the cows during or just before milking. 



(13) Horse manure must not be used as bedding. Only bedding 

 which is clean, dry and absorbent may be used. Preferably it should 

 be shavings, straw, fodder or dried leaves. 



NOTE: Each paragraph relates to an individual detail of milk production. The degree 

 of satisfaction with which the requirement that it contains is complied with is to be indicated 

 In the left hand margin by a system of crosses; one cross indicating that it is excellent 

 (certified dairy); two crosses that is good; three crosses that is fair; and four crosses that 

 it is bad. A naught signifies no effort or provision.
