FEEDING-STUFFS.
A sample designated as “Feeding Stuff Powder” was
found to contain proportions of constituents such as fat,
albuminoids, sugar and ash, indicating that the sample was
a skimmed milk powder. In the Society’s Schedule of Unit
Prices for February 1939 skimmed milk powder was given as
worth £20 per ton. I pointed out to the member who asked
for the analysis that the sample was not worth the figure
quoted. Two samples of meat and bone meal contained oil
to the extent of 115 and 16 per cent, and albuminoids t0 the
extent of 46 and 60 per cent respectively. It is natural to
expect that such a feeding-stuff as meat and bone meal should
show considerable variation in the proportions of the con-
stituents owing to the feeding-stuff being derived from a
waste product. The limits of variation in the proportions
of oil, albuminoids, and phosphoric acid in meat and. bone
meal are given in the Fertiliscrs and Feeding Stuffs Act, 1928.
The allowance as a deviation from the statutory statement
in the case of oil, albuminoids, and phosphoric acid is one-
tenth of the guarantee. The samples analysed were satis-

factory from the point of view of the prescribed limits of
variation.
The following table (Table V.) shows the proportions of the
nutritive constituents found in the undernoted feeding-stuffs.
it will be seen that blood meal contains the highest proportion
of albuminoids, followed by extracted herring meal—that is,
meal from which most of the oil has been extracted.

White fish meal contains a fairly constant amount of
plnlSphoric acid, round about 8 per cent.
A number of samples of pig meal was analysed. The pro-
portion of oil varied from 3 to 35 per cent; albuminoids
varied from 11-8 to 17 '97 per cent; While fibre varied from
4 to 65 per cent. All the samples were satisfactory samples
of pig meal. The following table (Table VI.) gives two
examples of mixtures suitable for pig feeding. White fish
meal is used in one case, while in the other case linseed cake
and extracted soya bean meal replace the White fish meal :—

included the usual compound cakes and meals, dairy meals,
