The manner in which butter tests are decided will be rendered clear by a
study of Table II. It is seen that whilst the much larger Shorthorn
cows--having a bigger frame to maintain and consuming more food--gave
both more milk and more butter in the day of twenty-four hours, the
Jersey milk was much the richer in fat. In the case of the first-prize
Jersey the "butter ratio," as it is termed, was excellent, as only 13.83
lb. of milk were required to yield 1 lb. of butter; in the case of the
second-prize Shorthorn, practically twice this quantity (or 27.11 lb)
was needed. Moreover, if the days in milk are taken into account, the
difference in favour of the Jersey is seen to be 123 days.

The butter-yielding capacity of the choicest class of butter cows, the
Jerseys, is amply illustrated in the results of the butter tests
conducted by the English Jersey Cattle Society over the period of
fourteen years 1886 to 1899 inclusive. These tests were carried out year
after year at half a dozen different shows, and the results are
classified in Table III. according to the age of the animals. The
average time in milk is measured by the number of days since calving,
and the milk and butter yields are those for the day of twenty-four
hours. The last column shows the "butter ratio." This number is lower in
the case of the Jerseys than in that of the general run of dairy cows.
The average results from the total of 1023 cows of the various ages
are:--One day's milk, 32 lb. 2(1/4) oz., equal to about 3 gallons or 12
quarts; one day's butter, 1 lb. 10(3/4) oz.; butter ratio, 19.13 or
about 16 pints of milk to 1 lb. of butter. Individual yields are
sometimes extraordinarily high. Thus at the Tring show in 1899 the three
leading Jersey cows gave the following results:--
+--------------+-------+-------+--------+------------+--------+

| Em | 7 | 864 | 44 | 3 4(3/4) | 13.32 |
+--------------+-------+-------+--------+------------+--------+
The eight prize-winning Jerseys on this occasion, with an average weight
of 916 lb. and an average of 117 days in milk, yielded an average of 2
lb. 9 oz. of butter per cow in the twenty-four hours, the butter ratio
working out at 16.69. At the Tring show of 1900 a Shorthorn cow Cherry
gave as much as 4 lb. 4(1/2) oz. of butter in twenty-four hours; she had
been in milk 41 days, and her butter ratio worked out at 15.79, which is
unusually good for a big cow.
In the six years 1895 to 1900 inclusive 285 cows of the Shorthorn,
Jersey, Guernsey and Red Polled breeds were subjected to butter tests at
the London dairy show, and the general results are summarized in Table
IV.
Although cows in the showyard may perhaps be somewhat upset by their
unusual surroundings, and thus not yield so well as at home, yet the
average results of these butter-test trials over a number of years are
borne out by the private trials that have taken place in various herds.
The trials have, moreover, brought into prominence the peculiarities of
different breeds, such as: (a) that the Shorthorns, Red Polls and
Kerries, being cattle whose milk contains small fat globules, are better
for milk than the Jerseys and Guernseys, whose milk is richer,
containing larger-sized fat globules, and is therefore more profitable
for converting into butter; (b) that the weights of the animals, and
consequently the proportionate food, must be taken into account in
estimating the cost of the dairy produce; (c) that the influence of the
stage reached in the period of lactation is much more marked in some
breeds than in others.

An instructive example of the milk-yielding capacity of Jersey cows is
afforded in the carefully kept records of Lord Rothschild's herd at
Tring Park, Herts. Overleaf are given the figures for four years, the
gallons being calculated at the rate of 10 lb of milk to the gallon.
In 1897, 30 cows averaged 6396 lb., or 640 gallons per cow.
In 1898, 29 " " 6209 " 621 " "
In 1899, 37 " " 6430 " 643 " "
In 1900, 39 " " 6136 " 614 " "
The average over the four years works out at about 630 gallons per cow
per annum.
Cows of larger type will give more milk than the Jerseys, but it is less
rich in fat. The milk record for the year 1900 of the herd of Red Polled
cattle belonging to Mr Garrett Taylor, Whitlingham, Norfolk, affords a
good example. The cows in the herd, which had before 1900 produced one
or more calves, and in 1900 added another to the list, being in full
profit the greater part of the year, numbered 82. Their total yield was
521,950 lb. of milk, or an average of 6365 lb.--equivalent to about 636
gallons--per cow. In 1899 the average yield of 96 cows was 6283 lb. or
628 gallons; in 1898 the average yield of 75 cows was 6473 lb. or 647
gallons. Of cows which dropped a first calf in the autumn of 1899, one
of them--Lemon--milked continuously for 462 days, yielding a total of
7166 lb. of milk, being still in milk when the herd year closed on the
27th of December. Similar cases were those of Nora, which gave 9066 lb.
of milk in 455 days; Doris, 8138 lb. in 462 days; Brisk, 9248 lb. in 469
days; Della, 8806 lb. in 434 days, drying 28 days before the year ended;
and Lottie, 6327 lb. in 394 days, also drying 28 days before the year
ended; these were all cows with their first calf. Eight cows in the herd
gave milk on every day of the 52 weeks, and 30 others had their milk
recorded on 300 days or more. Three heifers which produced a first calf
before the 11th of April 1900, averaged in the year 4569 lb. of milk, or
about 456 gallons. In 1900 three cows, Eyke Jessie, Kathleen and Doss,
each gave over 10,000 lb., or 1000 gallons of milk; four cows gave from
9000 lb. to 10,000 lb., two from 8000 lb. to 9000 lb., 17 from 7000 lb.
to 8000 lb., 19 from 6000 lb. to 7000 lb., 30 from 5000 lb. to 6000 lb.,
and 16 from 4000 lb. to 5000 lb. The practice, long followed at
Whitlingham, of developing the milk-yielding habit by milking a young
cow so long as she gives even a small quantity of milk daily, is well
supported by the figures denoting the results.
Though milking trials and butter tests are not usually available to the
ordinary dairy farmer in the management of his herd, it is, on the other
hand, a simple matter for him to keep what is known as a milk register.
By a milk register is meant a record of the quantity of milk yielded by
a cow. In other words, it is a quantitative estimation of the milk the
cow gives. It affords no information as to the quality of the milk or as
to its butter-yielding or cheese-yielding capacity. Nevertheless, by its
aid the milk-producing capacity of a cow can be ascertained exactly, and
her character in this respect can be expressed by means of figures about
which there need be no equivocation. A greater or less degree of
exactness can be secured, according to the greater or less frequency
with which the register is taken. Even a weekly register would give a
fair idea as to the milk yields of a cow, and would be extremely
valuable as compared with no register at all.
The practice of taking the milk register, as followed in a well-known
dairy, may be briefly described. The cows are always milked in the
stalls, and during summer they are brought in twice a day for this
purpose. After each cow is milked, the pail containing the whole of her
milk is hung on a spring balance suspended in a convenient position, and
from the gross weight indicated there is deducted the already known
weight of the pail.[2] The difference, which represents the weight of
milk, is recorded in a book suitably ruled. This book when open presents
a view of one week's records. In the left-hand column are the names of
the cows; on the right of this are fourteen columns, two of which
receive the morning and evening record of each cow. In a final column on
the right appears the week's total yield for each cow; and space is also
allowed for any remarks. Fractions of a pound are not entered, but 18
lb. 12 oz. would be recorded as 19 lb., whereas 21 lb. 5 oz. would
appear as 21 lb., so that a fraction of over half a pound is considered
as a whole pound, and a fraction of under half a pound is ignored. By
dividing the pounds by 10 the yield in gallons is readily ascertained.
Every dairy farmer has some idea, as to each of his cows, whether she is
a good, a bad or an indifferent milker, but such knowledge is at best
only vague. By the simple means indicated the character of each cow as a
milk-producer is slowly but surely recorded in a manner which is at once
exact and definite. Such a record is particularly valuable to the
farmer, in that it shows to him the relative milk-yielding capacities of
his cows, and thus enables him gradually to weed out the naturally poor
milkers and replace them by better ones. It also guides him in
regulating the supply of food according to the yield of milk. The
register will, in fact, indicate unerringly which are the best
milk-yielding cows in the dairy, and which therefore are, with the
milking capacity in view, the best to breed from.
The simplicity and inexpensiveness of the milk register must not be
overlooked. These are features which should commend it especially to the
notice of small dairy farmers, for with a moderate number of cows it is
particularly easy to introduce the register. But even with a large dairy
it will be found that, as soon as the system has got fairly established,
the additional time and trouble involved will sink into insignificance
when compared with the benefits which accrue.
The importance of ascertaining not only the quantity, but also the
quality of milk is aptly illustrated in the case of two cows at the
Tring show, 1900. The one cow gave in 24 hours 4(1/2) gallons of milk,
which at 7d. per gallon would work out at about 2s. 7d.; she made 2 lb.
12 oz. of butter, which at 1s. 4d. per lb. would bring in 3s. 8d.;
consequently by selling the milk the owner lost about 1s. 1d. per day.
The second cow gave 5(1/3) gallons of milk, which would work out at 3s.
1d.; she made 1 lb. 12 oz. of butter, which would only be worth 2s. 4d.,
so that by converting the milk into butter the owner lost 9d. per day.
The colour of milk is to some extent an indication of its quality--the
deeper the colour the better the quality. The colour depends upon the
size of the fat globules, a deep yellowish colour indicating large
globules of fat. When the globules are of large size the milk will churn
more readily, and the butter is better both in quality and in colour.
The following fifty dairy rules relating to the milking and general
management of cows, and to the care of milk and dairy utensils, were
drawn up on behalf of, and published by, the United States department of
agriculture at Washington. They are given here with a few merely verbal
alterations:--
