The fatting animal, if full grown, makes manure which is as good as that from animals that are not increasing in size, because the fat is taken from those parts of the food which is obtained by plants from the atmosphere, and from nature, (i. e. from the 1st class of proximates). Fat contains no nitrogen, and, consequently, does not lessen the amount of this ingredient in the manure.
Milch Cows turn a part of their food to the formation of milk, and consequently, they produce manure of reduced value.
How do the solid and liquid manure of the horse and ox compare?
What occasions these differences?
The solid manure of the horse is better than that of the ox, while the liquid manure of the ox is comparatively better than that of the horse. The cause of this is that the horse has poorer digestive organs than the ox, and consequently passes more of the valuable parts of his food, in an undigested form, as dung, while the ox, from chewing the cud and having more perfect organs, turns more of his food into urine than the horse.
RECAPITULATION.
Full Grown animals not producing milk, and full grown animals fattening make the best manure.
Growing Animals reduce the value of their manure, taking portions of their food to form their bodies.
Milch Cows reduce the value of their manure by changing a part of their food into milk.
The Ox makes poor dung and rich urine.
