During the whole period of sugar-feeding the R.M.W.-number was 
with NO, 2, 2.1 and with N° 3, 3.2 higher than the average before 
the 10% of January. With the controlling-cow on the other hand, a 
decline was recorded to the amount of 1.9. 
In order to be able to judge correctly of the effect of the 
sugar-feeding, it must be observed, that during the feeding with 
2 kilos of sugar, a tendency to decrease was noticed; evidently this 
quantity was too much U). 
When the daily allowance was diminished an actual rise was again 
recorded. Omitting the figures of the fat of the milk during the days 
when 2 kilos of sugar were given (20% and 234 Jan), the average 
rise of the R.M.W.-numbers of N°. 2 and 3 is 2.45 and3.7. The 
decrease with the controlling cow amounted on an average to 2.25, 
if the figures of the fat of the milk of No. 1 of 20th and 234 January 
are also omitted. 
If it be taken for granted, that the R.M.M.-numbers of the fat of 
the milk of the cows Nes, 2 and 3 would have decreased like those 
of No. 1, if these had not been fed on sugar, then the influence of 
the sugar-feeding is found, by adding the decrease which was noticed 
with the controlling-cow to the increase found with each of the 
cows fed on sugar, so that favorable influence of the sugar with 
No. 2 amounts to 4.7 and with No. 3 to 5.95. 
Of the results, recorded in Table II] concerning the R.M. W.-numbers, 
fig. III gives a graphic representation. The dates are put down on 
the X-axis, the R.M.W.-numbers on the Y-axis. 
For the experiment, in which first molasses and afterwards sugar 
was given, three of the cows, namely Nes. 1, 2 and 3 were uscd, 
which had also served for the experiment with heet-foliage. They 
were in the stables and were fed with oats, broken barley, linseed- 
cake, hay and straw. The quantities were different, considering the 
unequal age and the difference in the yield of milk. 
One of the cows, namely No. 2 was here the controlling-cow. 
The molasses used were absorbed in peat and contained about 
35 0/ of sugar. The daily allowance of molasses was gradually 
raised — from 24 Dec.—3 Jan. — to 1.5 kilo and lasted from 
3—14 Jan. As the cows were highly pregnant, I did not venture 
to give larger quantities. The quantity of sugar, which the animals 
took daily, amounted therefore only to about 0.5 kilo. From 14 Jan. 
1) That no other cause, except the sugar-feeding, is responsible for these decreases 
would appear from the fact, that, during these days the R.M.W.-numbers were not 
lower than otherwise for this controlling-cow, on the contrary rather higher.
