32 Bulletin 304 



calves raised in 1908-9, showing the least thrift, were those fed on Blatch- 

 ford's Calf Meal. These are shown as calves in Fig. 13 ; as two-year- 

 olds they are shown in Fig. 14. Their gains per day as calves averaged 

 .87 pounds, whereas the calves in Lot D, fed skimmed milk, made a gain 

 of I. S3 pounds. (Table XIV.) 



The same is true of the calves in Lot F, Fig. 11, fed Schumacher Calf 

 Meal. They have developed into animals of as good appearance and as 

 strong constitution as any of the animals raised from the calves of 1908-9. 

 In general it may be said that all the two-year-olds raised from the calves 

 of 1908-9 are of equally good constitutional vigor so far as any influence 

 may be attributed to the condition of the calves at five months of age, 

 due to the feeding of substitutes for skimmed milk. 



In some lots some of the individuals shown as calves are not shown in 

 the pictures representing the later development of the lot. This is for 

 two reasons: The males not shown in the later pictures have been 

 slaughtered, and the females not shown have died from one cause or 

 another in no way connected with the experiment. 



SUMMARY 



The writers of this supplement do not wish to put themselves on record 

 as maintaining that it does not matter how calves are fed, that the results 

 when they become two or three years old will be the same in any case. 

 Rather, it is intended to show that the heredity of the animal is of more 

 consequence than any moderate influence in the care or feeding for a 

 short time at the beginning of the development of the individual. If 

 the calf is not stunted permanently by continuing poor feed for too long 

 a time, the lack of thrift which might result from using a substitute for 

 milk from the time the calf is ten days or two weeks old until he is on 

 hay and grain entirely, may be overcome in the later development of 

 the animal if the dry food given from the time he is five months of 

 age is proper and sufficient in amount.
