No practice is more impolitic, than barely to sustain the stock through the winter, or a part of the year, as is the case in too many instances, and allow them to improve only when turned on grass in summer. Besides subjecting them to the risk of disease, consequent upon their privation of food, nearly half the year is lost in their use, or in maturing them for profitable disposal; when if one-third of the stock had been sold, the remainder would have been kept in a rapidly improving condition, and at three years of age, they would probably be of equal value, as otherwise at five or six. It is true that breed has much to do with this rapid advancement, but breed is useless without food to develop and mature it. CHAPTER II. NEAT OR HORNED CATTLE. The value of our neat cattle exceeds that of any other of the domestic animals in the United States. They are as widely disseminated, and more generally useful. Like sheep and all our domestic brutes, they have been so long and so entirely subject to the control of man, that their original type is unknown. They have been allowed entire freedom from all human direction or restraint for hundreds of years, on the boundless pampas of South America, California, and elsewhere; but when permitted to resume that natural condition, by which both plants and animals approximate to the character of their original head, they have scarcely deviated in any respect, from the domestic herds from which they are descended. From this it may be inferred, that our present races do not differ, in any of their essential features and characteristics, from the original stock. Various Domestic Breeds. Cultivation, feed, and climate, have much to do in determining the form, size, and character of cattle. In Lithuania, cattle attain an immense size, with but moderate pretensions to general excellence, while the Irish Kerry and Scotch Grampian cows but little exceed the largest sheep; yet the last are compact and well-made, and yield a good return for the food consumed. Every country, and almost every district, has its peculiar breeds, which by long association have become adapted to the food and circumstances of its position, and when found profitable, they should be exchanged for others, only after the most thorough trial of superior fitness for the particular location, in those proposed to be introduced. More attention has been paid to the improvement of the various breeds of cattle in England, than in any other country; and it is there they have attained the greatest perfection in form and character for the various purposes to which they are devoted. We have derived, directly from Great Britain, not only the parent stock from which nearly all our cattle are descended, but also most of those fresh importations, to which we have looked for improvement on the present race of animals.
