NOTE I. (p. 225).
Difference in Amount of Excreta voided for Food consumed.
With regard to the difference in the composition of the solid excreta voided by different fattening animals fed on the same amount of food, see Warington's 'Chemistry of the Farm,' p. 125, where it is shown that for equal amount of live-weight, the sheep produces on the same weight of dry food very much more manure than the pig, while the ox produces even more than the sheep. Of course this does not refer to the total amount of manure produced by the different animals, but only to the amount of manure produced from the consumption of equal quantities of food. This would seem to be owing to the greater capacity the pig has for assimilating its food.
NOTE II. (p. 227).
Solid Excreta voided by Sheep, Oxen, and Cows.
To contrast with the analyses given by Stoeckhardt, it may be well to cite those based on Lawes and Gilbert's experiments, and quoted by Warington ('Chemistry of the Farm,' p. 138):—
| Solid Excrement. | ||
| Fresh. | Dry. | |
| Water | 66.2 | — |
| Organic matter | 30.3 | 89.6 |
| Ash | 3.5 | 10.4 |
| Nitrogen | .7 | 2.0 |
II.—Oxen (fed on clover-hay and oat-straw, with 8 lb. beans per day).
| Fresh. | Dry. | |
| Water | 86.3 | — |
| Organic matter | 12.3 | 89.7 |
| Ash | 1.4 | 10.3 |
| Nitrogen | .3 | 1.9 |
