PERCENTAGE OF FOOD VOIDED IN THE SOLID AND LIQUID EXCREMENTS.

According to Wolff, the following table shows the percentage of the dry
substance of the food which is voided in the solid and liquid excrements
of the cow, ox, sheep, and horse:--

Cow. Ox. Sheep. Horse. Average.
Solid excreta 38.0 44.0 42.6 46.7 42.8
Urine 5.8 6.3 6.8 5.7 6.2
---- ---- ---- ---- ----
Total 43.8 50.3 49.4 52.4 49.0

PIG EXCREMENTS.

The excrements voided by pigs are poor in manurial constituents, because
the food on which they are fed is generally of a very poor nature. In
their case the urine is always very much richer in manurial ingredients
than the solid excreta. The relative composition of the solid excreta
and the urine will be best illustrated by quoting some experiments
carried out by Wolff on this subject. The experiments were carried out
with two pigs nine and a half months old, and each 121.9 kilogrammes (a
kilogramme is equal to about 2-1/4 lb.) in weight. The first consumed
daily 1000 grammes of barley, 5000 grammes of potatoes, and 2572 grammes
of sour-milk. The second one consumed the same quantities of potatoes
and sour-milk as the first, and 1000 grammes of peas. The following
table gives the results of excreta and urine daily voided, in grammes:--

Dry Nitrogen. Ash. Potash. Lime. Magnesia. Phosphoric
substance acid.
Solid { I. 217.7 8.7 28.6 7.3 4.4 3.0 10.3
excreta { II. 161.1 9.1 31.1 5.9 4.9 2.8 11.1

Urine { I. 112.8 19.3 56.2 33.0 0.4 0.9 6.7
{ II. 137.7 30.6 62.2 37.1 0.2 1.1 7.1
