DAIRY INSPECTION 177 
vidual milk from cows in this condition contains prop- 
erties which cause digestive and intestinal disturbances 
in infants; when sufficiently diluted with milk from cows 
in normal condition, it is not likely to have this effect. 
The presence of diarrhea also increases the difficulty of 
producing clean milk. No grain, meal, or fodder that 
is musty, mouldy, or otherwise unsound should be fed 
to milch cows. Diarrhoea has been observed in persons 
ingesting milk from cows receiving feed of this kind. It 
has been assumed that the diarrhoea was due to substances 
formed in the feed being excreted in the milk, but it is 
possible that in such cases the fungi or bacteria responsi- 
ble for the change in the feed pass directly from the feed 
to the milk after it is drawn from the udder and bring 
about decomposition changes. The use of distillery waste 
or slop and of wet brewers’ grains is prohibited by law 
in some sections. These substances when fed fresh in 
moderate quantity have no injurious effect upon the 
milk, but when they are fed in an advanced stage of 
fermentation or putrefaction the milk may cause diges- 
tive disturbances, especially in babies, and the manure 
of the cows has a bad odor and is very soft. In addi- 
tion, when these substances are fed it is difficult to keep 
the stable clean and free from bad odors, especially the 
mangers and storage bins or pits. Particles of the feed 
remain in corners and crevices and decompose, produc- 
ing a foul odor. On the other hand, dried distillers’ grains 
and dried brewers’ grains are entirely wholesome feeds. 
It is advisable to water the cows at least twice daily. 
Whether the water is given before or after feeding is 
of no consequence, but it is important that a sufficient 
quantity be given. The greater the milk production, 
the more water required.
