FARM AND STATION.

its food -is rich , hr carbohydrates (fat-pro-du'cers);'it;poihts"to the conclusion that both tii& yield "of milk and its richness in butter ! Me more, connected with a liberal supply of the nitrogenous "constituents in the food. Obviously,, sq far H3 this is the case, it may te only, that thereby more active change in the system, and therefore greater activity of the special function, is maintained. . . . Exercising Buoh care and reservation in regard to the numerous results of ourselves and others "which are at command, it may ■ be taken as clearly indicated that high feeding, and especially high nitrogenous feeding, does increase both the yield and the richness of milk. But it ie evident that, when high - feeding is pushed beyond a -comparatively limited range, the tendency is to increase the weight of the animal — that is, to favour the development of the individual, Tather than to enhance- the activity of the functions connected with the reproductive system. This is, of course, a disadvantage when the object is to maintain the milkyielding condition of the animal; but when a cow is to bo fattened off it will be otherwise." In conclusion, it may be remarked that these Rothamsted experiments have very clearly illustrated how very much greater is the demand upon the food, especially for nitrogenous and for mineral constituents, in the production of milk 1 , than in that of lattening increase.
