Improvement of Dairy-Cattle

Improvement of Dairy-Cattle.

What special steps have been taken by New Zealand dairy-farmers to improve their cattle I do not know, but, inasmuch as the great dairy-competitions in England have conclusively shown that there are milking-cows of the highest type belonging to all the Hading breeds, and that it is possible, by careful selection, to obtain not only deep but rich milkers, I am of opinion that the Government of the colony could do no greater service to the agricultural community than to purchase a small number of carefully-selected animals of the Dairy Shorthorn and the Ayrshire breeds, for the purpose of improving the milking-properties of New Zealand cattle. There are numbers of landowners and farmers, both in England and Scotland, who possess herds of cows, many of which yield, in the case of the Shorthorn, from 700 to 1,000 gallons per head, and in the case of the Ayrshire from 700 to 900 gallons per head per annum. As, however, there is no herd-book for dairy-cattle, by the aid of which a purchaser would be able to select bulls with milking pedigrees, I would suggest that a few of the heaviest milking-cows obtainable should be purchased for the purpose of breeding bulls for use in the colony. If a dozen bulls were selected—and I believe considerable difficulty would be experienced in obtaining bulls which were known to be bred from milkers of the very highest type—the colonists would not receive the same guarantee of the milking-properties of the strain which each bull would represent as would be page 76 the case if bulls intended for their use were bred directly from the very finest milking-cows which could be selected and sent out to the colony for breeding. A score of males and females of the two milking-races to which reference has been made would virtually form a Government breeding-herd, which might be attached to the agricultural college or to an experiment-station, and they might become the nucleus of a greatly-improved race of cattle. Many cows have been exhibited at the London dairy-shows which have exceeded a yield of 60lb., or about 6 gallons, of milk daily, although under circumstances which must have diminished their yield. During nine years eighty-eight Shorthorns have competed at the London shows for milking-prizes. They have averaged 12.87 per cent, of solids and 3.71 per cent, of fat. In 1887 the average of fifteen cows was 13.18 per cent, of solids and 3.89 per cent, of fat. In the same year seven of these, cows and heifers, exceeded 4 per cent, of fat. One cow gave 4.5 per cent, in the morning and 4.9 per cent, in the evening another gave 4.4 per cent, in the morning and 5 per cent, in the evening; a third cow gave 5½ per cent, both morning and evening; and a heifer gave 6 per cent, at each milking, her yield of milk on the same day being 43.2lb.; and yet farmers are content to goon making 3 per cent, of butter from their milk. Of the sixteen Short-horns which competed for the milking-prizes in October, 1888, none averaged less than 3 per cent, of fat, whereas twelve gave over 4 per cent, at one or both milkings, nine gave over 4½ per cent., and four over 5 per cent. Most of these were heavy milking-cattle, and of the greatest value for the improvement of colonial stock. On one occasion I selected eight animals from some twenty head of Dairy Shorthorns which had been collected for the purpose by a dealer, six of which were cows of about five years of age, and two heifers. They had been fed solely upon hay for a few days, and had recently calved. The following statement shows the quantity of milk which they gave during two and a half days' test, showing that 18½lb. of their milk made lib. of butter:—

The milk averaged 5.3 per cent, of butter-fat, as ascertained by the churn. The milk was passed through a separator, and the beam properly ripened and subsequently churned at 60°. These cows originally came from different farms. On this occasion I made no test in order to ascertain the quality of the milk. Every cow which was selected for purchase, in addition to others, was milked clean upon the dealer's farm before a bargain was made, and in the end those were selected which gave the largest quantity of milk. The cows had not been stocked, as my visit on that particular day was not expected.

From time to time records of various herds have appeared in the "Agricultural Gazette," showing the average yields of herds of dairy-cows from year to year; and those who have followed the question will have thoroughly understood how these herds have been formed, and that it is possible, by adopting a similar plan, to achieve similar Cults in the Colony of New Zealand. Like many other persons who have followed the simple plan which has been referred to, I have been enabled to purchase Ayrshires from Scotch breeders who have allowed me to take their best cattle and to see them milked before purchase. To a great extent, therefore, it depends upon the enterprise of colonial farmers whether they are enabled to materially Reprove the yield and quality of the milk, but they can be largely Biped by the Government, which would be able to achieve such results as the farmers themselves could scarcely hope to attain. The breed of the cow, however, is not all that the farmer requires, for to arrive at the best results I believe he will find it necessary to pay closer attention to the system of feeding, to which reference is made in this report. If it can be shown in practice that by the assistance of artificial food a greater money-return can be made—whether as regards quantity or quality of milk it matters little—then it will be to the interest of the farmer to commence artificial feeding, more especially as he reaps considerable benefit from the extra value the manure; the manure made from such a food as cotton-cake being very high in value, if it is not, indeed, as much in value as one-half the first cost of the cake.
