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 diarrhoea 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.
