In both cases the wholesaler had been supplying poor quality milk. The
figures given above show the original supply to consist of very good quality
milk, which would require about 5 per cent. of added water to reduce the
composition to the minimum limit of 8.5 per cent. of solids-not-fat or slightly
under, as the milk is received by the consumer.
During the latter part of the year 0 institutions were sampled, 20 samples
being taken. All the samples complied with the requirements of the L.C.C.
contract for this period, viz.:—Milk fat 3.25 per cent. and solids-not-fat
8.50 per cent.
Hospital,
etc., Samples
Samples L 38, L 39 and L 41, all deficient in fat, were taken on delivery
at the cowshed. The cowshed from which sample L 41 was taken contained
45 cows, and seven further samples from these were taken, the herd being
divided into seven groups. Of these seven samples three were unsatisfactory.
The calculated composition of the bulked milk of the 45 cows just satisfied
the standard.

Calculated composition of bulked milk3.078.50

The 24 cows represented by the three unsatisfactory samples were sampled
and of these 16 failed to comply with the requirements of the minimum
standard. The bulked milk of these cows (from the calculated composition)
would be reported as poor quality milk.
