144 SHEEP DISEASES. 



one is often asked about these questions, and the 

 following is given for information: 



Agalactia or absence of milk. This is a symp- 

 tom, and one of the first symptoms of disease in 

 a milking ewe. A form of infectious agalactia has 

 been observed among ewes and goats. It is of 

 unknown origin. 



Watery milk. This is due to an absence of fats 

 and casein; the milk is of a bluish color. By 

 changing the food and administering tonics, the 

 condition may be improved. 



Fatty milk. This is found among ewes that 

 have been fed on rich, concentrated foods, such 

 as oil cake, and in ewes suffering from lack of 

 exercise. Diarrhea ensues among the lambs. The 

 treatment is less food, more exercise and an abun- 

 dant supply of water. 



Curdling milk. A symptom of indigestion, 

 mammitis, poisoning, overheating, and of ad- 

 vanced pregnancy. To alleviate this condition, a 

 tablespoonful of sodium hyposulphite may be 

 given once daily. 



Fermenting milk. Cause and treatment same 

 as above. 



Putrescent milk. Caused by an invasion of bac- 

 teria in the udder. Treatment is the same as for 

 curdling milk, or fattening for slaughter. 



Slimy, stringy and soapy milk. Caused by fungi 

 and bacilli. Rather rare. Treatment similar to 

 that for curdling milk. 



Blue milk, due to the Bacillus cyanogenus. 



Red milk, caused by the Bacillus prodigiosus. 



Yellow milk, caused by the Bacillus synxanthum.
