Feeding of calves by hand is also, in various respects, advantageous. Instead of depending on the uncertain, or perhaps precarious supply of the dam, which may be more at first than the young animal can consume or digest, and at other times too little for its supply, its food can, by hand-feeding, be regulated to suit the age, appetite, and the purposes for which the calf is intended; other admixtures or substitutes can be introduced into the milk, and the quantity gradually increased or withdrawn at pleasure. This is highly necessary when the calves are reared for stock. The milk is in that case diminished, and other food introduced so gradually that the stomach of the young animal is not injured as it is when the food is too suddenly changed. And, in the case of feeding calves for the butcher, the quantity of milk is not limited to that of the dam--for no cow will allow a stranger-calf to suck her--but it can be increased, or the richest or poorest parts of the milk given at pleasure. Such are, substantially, the views upon this subject which are entertained by the most judicious farmers in the first dairy districts of Scotland. In those districts--where, probably, the feeding and management of calves are as well and as judiciously conducted as in any other part of Great Britain--the farmers' wives and daughters, or the female domestics, have the principal charge of young calves; and they are, doubtless, much better calculated for this duty than men, since they are more inclined to be gentle and patient. The utmost gentleness--as has been already remarked, in another connection--should always be observed in the treatment of all stock; but especially of milch cows, and calves designed for the dairy. Persevering kindness and patience, will, almost invariably, overcome the most obstinate natures; while rough and ungentle handling will be repaid in a quiet kind of way, perhaps, by withholding the milk, which will always have a tendency to dry up the cow; or, what is nearly as bad, by kicking and other modes of revenge, which often contribute to the personal discomfort of the milker. The disposition of the cow is greatly modified, if not, indeed, wholly formed, by her treatment while young; and therefore it is best to handle calves as much as possible, and make pets of them, lead them with a halter, and caress them in various ways. Calves managed in this way will always be docile, and suffer themselves to be approached and handled, both in the pasture and in the barn.
