VAN PELT'S COW DEMONSTRATION 



"drooping rumped." This conformation not only detracts 

 from the beauty of the cow, but as a rule those cows which 

 droop at the rump also have tilted or slanting udders a por- 

 tion of which seems to have been cut away, and this naturally 

 detracts from the ability of the cow. 



On the other hand, those cows which carry out straight 

 from the hip bones to the pin bones have udders that are 

 straight on the bottom, symmetrical and carry well forward 

 with each quarter large and uniform in size. The fact that 

 the length of udder can be determined by the length from 

 the hip bone to the pin bone, and the shape of the udder 

 by the manner in which the rump is carried out, is likely 

 due to the law of correlation of parts, which enables the 

 anatomist, when he finds a bone, to determine from its di- 

 mensions the dimensions of every other bone in the animal's 

 body from which it came. 



The association of the drooping rump and the tilted udder 

 appears with more certainty in families than in individual 

 animals. In. some of the dairy breeds there are families of 

 cows that have been bred for many generations without re- 

 gard to the length and straightness of tailhead. Invariably 

 in these families a large percentage of animals are found that 

 are miserable appearing "critters" and at the same time are 

 handicapped in their ability to yield profitably because part 

 of their udders are gone. 



Even though in certain individuals that droop at the 

 rump the udder is not very perceptibly faulty it may be taken 

 as a rule that if offspring are continuously bred from animals 

 of this conformation the associated characteristics will in time 

 follow.
