ALL cows ARE NOT WHAT THEY SEEM.

The percentage of butter fat In milk
cannot be determined from the appear
ance of the COW and it cannot be
changed greatly by care or feeding.
Good care and feeding increase the
quantity of milk given by the COW.
hence the total butter fat produced is
increased. The percentage of butter
fat, however, remains fairly constant
for each individual, except that varia-
lions may occur with the period of lac
tation, the first and last parts OF the
milking, and the age of the COW.
Calculation of Records.
The daily weights of milk produced
by each COW are added and the total
for the month multiplied by the per-
centage of butter fat in the milk to
obtain the amount of butter fat pro-
duced during the month. For exam
pie, the cow Fannie gave 1,1O1.6
pounds of milk in January, 1913, and
it tested 40 per cent. Then 1,101.G <
40 per cent=54.17 pounds Of butter
fat.
The next step is the calculation of
the value of the butter fat, which in
this case was 80 cents per pound. Thus
Fannie produced 54.17 pounds of but
ter fat, worth S1S.96. Similar calcu-
lations are made for the other COWS
and entered on the milk sheet.
The value of the skim milk is deter
mined by calculating the skim milk as
so per cent Of the whole milk and Civ
ing it a value of % cents per 100
pounds. Thus, Fannie is credited with
SS4 pounds of skim milk, which is gu
per cent of 1,1O5.6, worth 1921.
The value Of the skim milk is added
to the value of the butter fat, and the
total cost Of the feed consumed Is
deducted to obtain the profit over the
cost of the feed. Thus Fannie's but
ter fat was worth $1S.06. and the skim
milk, 1921, a total of SPLIT. Deduct
ing the cost Of her feed, S7.S3, leaves
1884 profit In January. This COW has
good dairy conformation, a we'll
shaped udder, and good barrel capac
ity, indicating that she can turn large
quantities of roughage into milk.
Diamond, No. 81, shows a profit OF
1924 or only about half as much as
Fannie. We must, take into consid
Grafton, however. the fact that Fannie
had but recently freshened, while Dia
mond was well along in her lactatior
period.
Diana, No. 81, shows mucf
smaller profit, namely, S3.01, although
she produced within pounds of thu
quantity of milk produced by Diamond
This is due to the fact that her mill
tested IA per cent less, which made
difference Of pounds of butter ia
for the month, and that she consumed
more feed than Diamond.
Pet, No. CT, produced only 451 pound
Of milk. but it tested Sc per cent. max
ing 25.2c pounds Of butter fat. Sh
ate less, so that her feed cost wa
S5.13 as compared with $40 fo
Diana. With high percentage of but
ter fat in her milk, and a smalle
quantity of feed consumed, her prof
was S4.61 for the month.
Myrtle was near the end of her lac
tation period. so that her feed cos
was S1.55 more than the value Of til
milk produced. She has poor dair
conformation and judged only by he
January record might have been elm
mated from the herd. 1t must b
noted, however, that she was nearl
dry. During the year she never pre-
duced n very large quantity of milk q
milking, but she was a perslsten
mixer, so that in profit over cost @
feed she stood second in the herd.
Ellen was dried off early in tn
month, and although the cost Of he
feed was only S2.72. her loss for tn
month was S1.41. She Is more Of
beef than q dairy type, and her recor
for the year shows that she was DIR
four months and produced only 153.
pounds of butter fat.
Blanche freShened the latter part {
the month and showed loss of Z
cents. Her profit for the year wa
only S1945. owing to her low produ
ton and to the large quantity of fee
she consumed.
These records clearly show that or
months record Is not sufficient ev
dence to condemn COW, for the 10
production may be due to advance
lactation (the COW may be nearly dry
illness. lack of proper feed (the pa
ture may have dried up). etc. Too o
ten the results shown on the recor
sheet fail to confirm the judgment {
the owner.
