CATTLE CATTLE 315 main factors that will decide how narrow nutritive ratios can be profitably fed in different localities ; where nitrogen feeds are relatively cheap, they can enter more largely into the make-up of the rations than where the opposite conditions obtain. We may say, in general, that a good dairy cow in full flow of milk should receive twenty-five pounds of dry matter, fifteen to eighteen pounds of digestible matter, and at least two pounds of diges- tible protein. Cows of large productive capacity may be fed to advantage considerably larger quan- tities of food materials than those given, while low producers, or dry cows, require much less. For dry cows, rations containing less than twenty pounds of dry matter, twelve pounds of digestible matter and one and one-half pounds of digestible protein are ordinarily sufficient to maintain body weight and insure a normal development of the foetus, if they are in calf. In discussing the feeding of dairy cows, we may conveniently consider separately the summer period when the cows are pastured or fed soiling crops, and the winter period, when they are fed winter rations in the stable. (1) Summer-feeding of dairy cows.—The favor- able influence of early summer pasturage on the milk secretion of cows, both as regards yield and quality, and more especially its fat content, has been known to observing dairy-farmers as long as milk records have been kept or tests of milk have been made. Ample pasturage is one of the essen- tials of successful dairy-farming where the soiling system has not been introduced. In the early part of the season, the cows, as a rule, will find a sufficient food supply on the pasture alone; but, later in the season, it will often be necessary to supplement the pasture with soiling crops or summer silage, or, if neither is available, to feed grain feeds. Trials at a number of experiment stations have shown that the feeding of g
