574 EXPERIMENT STATION RECORD. [Vol. 40 



The cows used were from the station herd. In each experiment a group of 

 cows were given a test ration and a check ration alternately every two weeks. 

 The check rations were the common dairy rations of Kentucky — corn meal and 

 wheat hran, with or without cottonseed meal as a supplement. The test mix- 

 tures, in which velvet-bean meal replaced part or all of the bran, were cheaper 

 by from 50 cts. to $2.25 per ton than the check grain mixtures. The experi- 

 ments were as follows : 



(1) Corn meal, wheat bran, and velvet-bean feed (2:1:1) v. corn meal and 

 wheat bran (1:1). The average daily milk yield i»er cow during the feeding 

 of these rations were, respectively. 26.94 and 20.72 lbs. Eight cows were used 

 for seven months, beginning May 20, 1917. They had scanty bine-grass pasture 

 during the summer and corn silage and soy-bean hay in the winter. 



(2) Corn-meal and velvet-bean feed (1:1) P. corn meal and bran (1:1). 

 The respective milk yields per day were 10.04 and 10.94 lbs. Three cows were 

 tested for eight weeks in January and February, 1918. Soy-bean hay and corn 

 silage were the roughages fed. 



i.'')) Corn-meal and velvet-bean feed (1:11 r. corn meal, wheat bran, and 

 cottonseed meal (4:3:1). The respective milk yields pel day were 22.12 and 

 22.48 lbs. The daily roughage was 38 lbs. corn silage and lbs. barley straw 

 welted with molasses and water. 



(4) Corn meal, wheat bran, ami palm-kernel meal (2:1:1) v. corn meal 

 and bran (1:1). The respective daily milk yields were 22.77 and L"J.41 Lbs, 

 Seven cows were fed 24 weeks, beginning June 24, 1917. The roughage was 30 

 lbs. of corn silage and 8 lbs. of soy-bean bay. 



(5) Corn meal, wheat bran, cottonseed meal, and palm kernel meal (4:1: 

 1:2) v. corn meal, bran, and cottonseed meal (4:.'!: It. The respective daily 

 milk yields were 20.75 and 20.94 lbs. Four rows were fed 1'2 weeks, beginning 

 February 10, 1918. The roughage was 30 lbs. of silage, 6 lbs. of barley straw, 

 and 1 lb. of molaSS 



(0) Rolled barley, crushed oats, ami velvet bean feed (2:1:1) ?\ corn meal 

 and wheat bran (1:11. The respective dally milk yields were 17.4!) and 10.01 

 lbs. Bight cows were used for ."{0 weeks, beginning Augusl •">, 1917. During 

 the winter 10 lbs. of soy bean bay and 20 lbs. of corn silage were ted daily. 

 The barley, oats, and velvet-bean mixture is stated to have been one of the 

 mosl satisfactory rations used at the station. At the beginning of the experi- 

 ment oats and barley were low priced. During the winter the price of both 

 went up, while that of bran dropped, bo thai the check ration became cheaper 

 than the test ration. 



No insistence Is placed on the difference between the milk yields in any of 

 these experiments. It is held that all the test rations should prove satisfac- 

 tory for milk production. 



Grain rations for dairy stock, J. B. Lindsey ( Massachusetts sta. Control 

 Set: Bui. 10 (1918). pp. 98, -'■>'>. Bight combinations ,.f grains suitable for 

 dairy animals are given here, as well as a ration for pigs. They are designed 

 particularly for use during a wheat shortage when barley and oat residues are 

 available. 



Profits from milk cows on general corn-belt farms. O. R. Johnson and 

 R. M. Greer {Missouri Sta. Bui. tr>:' 1 1918), pp. 20. fins. 5).— This bulletin deals 

 with the type of dairying practiced on small general farms where only a few- 

 cows are kept and much of the product is consumed by the operators family. 

 It is based on 41 yearly records of some .'14 farms scattered throughout the 

 State of Missouri. The four years 1912 to 191. r > are represented. On these 

 farms the raising of corn, wheat, and hogs was the most important enterprise.
