Corn-and-cob meal vs. wheat for fattening steers, II. J. Waters, 

 \V. C I'ATTERSOX, and K. II, IIkss [Peiinsylrania t<^ta. ]\pt. IS!):'), pp. 

 107-110). — A feeding test was made with 20 high-grade Shorthorn 

 steers about 31 months okl, to compare corn-and-cob meal with chopped 

 wheat. The test was divided into 3 periods. The first period began 

 Xovember 20 and histed ."JO days. All the steers were fed a mixed 

 grain ration consisting of equal parts by weight of corn-and-cob meal 

 and cliopi)e(l wheat. In addition, corn stover and hay ad lihitnm were 

 fed on alternating days. The nutritive ratio of the ration was 1: 11.2. 

 The period was preceded bj^ a preliminary test of 3 weeks on the 

 same ration. The second period began December 20 and lasted 34 

 days. The animals were divided into 2 uniform lots. Lot 1 was fed 

 corn-and-cob meal and lot 2 chopi^ed wheat, with the same coarse 

 fodder as iu the first x>eriod. The nutritive ratio of the ration fed lot 

 1 was 1 : 13.3, and lot 2, 1 : 10.1. The third period began January 23 and 

 lasted 30 days. All the animals were fed the same ration as in the 

 first period. 



The weight of the food eaten by each lot during each period was 

 determined, and on 1 day of each week the uneaten residues of corn 

 stover and of hay were weighed. The moisture was determined in 

 samples of the coarse fodder in each period, and corresponding cor- 

 rections introduced in computing the composition of the material. 

 The results are expressed in full in tabular form. The average results 

 are given in the following table: 



Residts of experiments in feedimj corn-and-cob meal and wheat to steers. 



The authors conclude that corn has a slightly higher value for fat- 

 tening steers than wheat. 



The relation of food to the growth and composition of the 

 bodies of steers, W. H. Jordan {Maine iSta. Bpt. 1895, pp. o0'-77). — 

 The object of this experiment was to determine the effect of wide and 

 narrow rations upon the rate of growth and the composition of the 

 bodies of 1 high-grade Shorthorn steers, 5 to 7 months old at the begin- 

 ning of the test. Steers 1 and 2 were fed a ration rich in protein, hav- 

 ing a nutritive ratio of 1 : 5.2, and containing linseed meal, corn meal, 

 and wheat bran, in different proportions. Steers 3 and 1 were fed a
