134 DAIRY FARMING 



3. The richness of milk is also influenced by the length 

 of time that elapses between the milkings. In general, 

 the shorter the time between the milkings the richer the 

 milk. This, no doubt, in a large measure accounts for 

 the differences we often find in the richness of morning's 

 and night's milk. Sometimes the morning's milk is the 

 richer, at other times the evening's, depending largely 

 upon the time of day the cows are milked. Milk can not, 

 however, be permanently enriched by milking three times 

 in stead of twice a day. 



4. Unusual excitement of any kind reduces the quality 

 of milk. The person who abuses cows by dogs, milk 

 stools, or boisterousness, pays dearly for it in a reduction 

 of both the quality and the quantity of milk produced. 



5. Starvation also seriously affects both the quality 

 and the quantity of milk. It has been repeatedly shown, in 

 this country and in Europe, that under-feeding to any 

 great extent results in the production of milk poor in fat. 



6. Sudden changes of feed may slightly affect the 

 richness of milk, but only temporarily. 



So long as cows are fed a full ration, it is not possible 

 to change the richness of milk permanently, no matter 

 what the character of feed composing the ration. 



7. Irregularities of feeding and milking, exposure to 

 heat, cold, rain, and flies, tend to reduce both the quantity 

 and the quality of milk produced.
