It was found from these analyses that the deficiency in fat in the morning
milk was largely due to the unequal periods of milking, which varied from
8½ hours and 15½ hours to 6½ hours and 17½ hours.
There are 18 cowsheds in the Borough containing in all about 425 cows.
The cows are milked at about 6 a.m. to 8 a.m. in the morning, this milk being
sold at once, and then again at about 3 p.m. for the afternoon delivery ; in
this way the unequal periods are caused. To avoid this and to adopt approximately
equal periods of milking it would be necessary to reserve the morning
milk for the afternoon delivery and the evening milk for the following morning.
