RECENT AMERICAN WORK ON FEEDING STUFFS. 533 



A few feeding experiments have been carried on by American 

 invostitifator.s not connec^ted with experiment stations, thus Mari^aret 

 B. ^Vilson" studied the growth of suckling pigs fed on a diet of 

 skimmed cow's milk. 



Several investigators have reported more or less extended data 

 regarding the feeding value of molasses for horses; for instance, G. H. 

 Berns'' reported tests in which molasses was successfully employed as a 

 part of the ration for a large number of horses for a considerable time. 



A number of the stations have published general discussions of feeding 

 problems and summaries of the results obtained. A number of text- 

 books and other treatises discussing the subject have also been issued. 

 Several publications have been prepared ])y American authors which 

 discuss the feeding of squabs and pigeons and quails in captivit}^ on 

 the basis of personal experience. 



The following works l)y station officials dealing with the general sub- 

 ject of feeding should be mentioned: The Feeding of Animals, by 

 W.H.Jordan; New York, 1901. Feeds and Feeding, fourth edition, 

 by W. A. Henry; Madison, Wis., 1902. The Principles of Animal 

 Nutrition, by H. P. Armsby; New York, 1903. The Chemistry of 

 Plant and Animal Life, l)y H. Snyder; Easton, Pa., 1903. 



DIGESTIBILITY OF FEEDING STUFFS. 



At about the date stated as the beginning of the period covered by 

 this summary, a bulletin was published by W. H. Jordan and F. H. 

 Hall.' summarizing the American digestion experiments with farm 

 animals, exclusive of poultry. Since that time a number of the stations 

 have issued bulletins discussing the subject and have published more 

 or less complete summaries of coefficients of digestibility. One of 

 these by J. B. Lindsey and N. J. Hunting,^ of the Massachusetts Sta- 

 tion, contains a reasonably complete summary of the American work, 

 including the results of the experiments with I'ununants, swine, horses, 

 and poultry. A summary of digestion experiments with sheep car- 

 ried on at the Massachusetts Station was recently published by J. B. 

 Lindsey et al.* 



The experiments on the digestibility of diflferent feeding stuflfs 

 pul>lished during the period under consideration include the following: 



The digestibility of Kafir corn, maize, and cowpeas, ground and 

 unground, was tested with chickens })y J. Fields and A. G. Ford.-'" 



II. Snvder and J. A. Hummel-' studied the diiiestibilitv of hotr-millet 

 seed with a pig, finding that this material is equal in digestibility to
