March, 1936] Maintenance of Grade A Milk 19 



There was no marked difference between the A and B producers in the num- 

 ber of times the stable was cleaned during the summer months. During the 

 winter months the Grade A producers cleaned the stable on an average of 

 three times daily, compared with two times daily for the B producers at 

 Pattee and three times for the B producers in Monroe. On a per cow basis 

 the time spent in cleaning the stable daily by the Grade A producers aver- 

 aged a little higher during the winter and summer months than either of the 

 Grade B groups. The amount of sawdust used for bedding per cow in a 

 month's time by the Grade A producers was almost identical with the B pro- 

 ducers at Pattee, but about 40 per cent greater than the B producers in 

 Monroe. (See Table 7.) 



Milkhouse: Practically no important differences were noted between 

 the A and B producers so far as the milkhouse was concerned. Nearly all 

 had good drainage. The B producers were more careless in preventing dust 

 accumulations in and around the milkhouse and in screening out the flies 

 than were the A producers. More B producers in Monroe washed and 

 cleaned the floors daily than did either the A or B producers at Pattee. One 

 reason for this was that 87 per cent of them had running water available 

 in the milkhouse compared with 49 per cent of the Grade A producers. 



The Grade A dairymen who were cooling the milk with ice entirely used 

 it an average of 191 days compared with 175 days for the Grade B dairy- 

 men at Pattee and with 136 days for those in Monroe. One B producer in 

 Monroe used up his entire ice supply in two months' time. This man claimed 

 he spent about three hours daily during the winter months in grooming the 

 cows. He might better have used most of this time in cutting and putting up 

 ice so as to have a sufficient supply for the entire summer season. When 

 the three groups are compared as to the pounds of ice used per cwt. of 

 milk, there is no apparent difference ; but the longer period of using ice by 

 the Grade A dairymen over the B dairymen in Monroe represents an addi- 

 tional cost in caring for Grade A over Grade B milk. On this basis the 66 

 Grade A dairymen would use over 364 tons of ice more than the B dairymen 

 in Monroe in cooling the same amount of milk per season. If this extra 

 amount of ice is figured at $6.50 per ton (the price at which ice was sold and 

 delivered) , the cost would be $2,366 or 9.3 cents per cwt. for all milk cooled 

 in the summer season. (See Table 7.) 



Current Expense: All Grade A dairymen are supposed to use a small 

 top pail when milking by hand. Of the group considered in this analysis, 

 only 8 or 10 per cent of them did not have a small top pail as part of their 

 equipment; 47 per cent of the B producers at Pattee and 70 per cent of the 

 B producers at Monroe did not use small top pails. 



When the replacements of rubber for milking machines were compared, 

 the Grade A producers were found to have about twice as much expense 

 for rubber inflations, as they changed them on an average of every 3.7 

 months compared with over seven months for the B producers. The short 

 and long rubbers on the machines of the Grade A producers were changed 

 about every eight months, or approximately two to four times as often as 

 those of the B producers. Inflations usually cost 75 cents each, and a set 

 of short and long rubbers about $2.50. On this basis the approximate cost 

 of rubber for a single unit machine of a Grade A producer would be $13.35 

 yearly, $6.05 for the B producer at Pattee, and $6.52 for the B producer 

 in Monroe. (See Table 7.)
