DAIRY FEEDS 6i 



Milk contains a sugar called milk sugar which has the 

 same composition as cane sugar. 



The commercial value of cows' milk is generally estab- 

 lished by its fat content, which may vary from 3 per cent 

 or less to over 5 per cent. The fat content varies with 

 individual animals, the stage of lactation, and the progress 

 of the milking. The fat content of milk increases as the 

 lactation period advances, and last drawn milk is richer 

 in fat than first. 



At the present time butter fat commands such a high 

 price that few people can afford to feed whole milk except 

 in those rare cases where it is fed to choice young animals 

 that are kept for breeding or show purposes. 



Skim Milk. — Milk from which the fat has been removed 

 is proportionately higher in protein and ash than whole 

 milk. It is valuable for rearing calves, and is the cheapest 

 and most reUable feed for this purpose. It is one of the 

 best feeds for young pigs. Five or six pounds of skim 

 milk has the same feeding value as one pound of cqrn. 

 Skim milk may also be fed to young colts after weaning, 

 with good results. 



Buttennilk. — Buttermilk is the by-product from butter 

 manufacture. It has practically the same composition as 

 skim milk, and if the material has not been too badly 

 diluted, as is often done at creameries, it is equal to skim 

 milk as a feed for pigs. 



Whey. — Whey is the by-product derived from cheese 

 factories and it is only with difficulty that thrifty calves can 

 be reared upon it. For pigs it has about half the feeding 

 value of skim milk and should be fed in connection with a 

 good grain ration. Whey should be fed fresh. If exposed 

 to the sun in filthy tanks it is not suitable for feeding.
