FOOD EFFECT ON MILK SECRETION. 213 



nutritive ratios were 1 to 6.8 and 1 to 6 . 1 respectively. A difference of .34 

 of a pound of milk per day was realized in favor of the corn meal. 



CORN MEAL AND COTTQNSEED MEAL. The same station 1 found 

 that a ration with corn meal, having a nutritive ratio of 1 to 5.5 and one 

 with cottonseed meal, 1 to 4.5 gave a gain of .44 of a pound of milk more 

 per day per cow in favor of the cottonseed meal. Of the five cows one gained 

 on the wide ratio, two remained the same and two gained on the narrow 

 ratio. 



CORN MEAL AND GLUTEN MEAL. Corn meal was used in a ration 

 having a nutritive ratio of 1 to 9.2, and the gluten meal at 1 to 2.4. This 

 resulted in a decrease in the flow of milk each time the change was made 

 from the narrow to the wide ration. Gluten meal also made a softer butter 

 than the corn meal. 2 



BRAN AND OATS. Have about equal values. 3 At the Wisconsin 

 Experiment Station, two feeding experiments were carried on for the pur- 

 pose of ascertaining the value of ground oats and bran for milk production. 

 The cows were fed the same quantities by weight of bran and oats, eight 

 pounds daily per head in the first experiment, and ten pounds daily in 

 the second, with an addition of corn meal, hay, corn silage, and corn fodder. 

 It was found that the cows invariably did better on the oats. The fat 

 content on the average remained the same. 



BARLEY AND OATS, and a mixture of palm nut meal, rape seed cake 

 and sunflower seed cake, were compared in co-operative experiments in 

 Denmark. There was no change in the chemical composition of the milk 

 from the different rations, although the quantity of the milk increased 

 with the heavier oil cake feeding. 



GLUTEN MEAL AND COTTONSEED MEAL. Gluten meal was found 

 equal to cottonseed meal when fed in such quantities as to make the digestible 

 matter equal. 4 At the Massachusetts Station these feeds gave practically 

 the same results. 



GLUTEN MEAL AND OTHER MEALS. Seventy cows were used in a 

 test to determine the comparative value of gluten meal and corn meal 

 and bran. 5 High grade gluten meal was found to have a higher feeding 

 value than equal weights of corn meal and bran. The milk was slightly 

 richer, but not sufficiently so to be of practical importance. The fat was 

 disproportionately increased to other solids. 



GLUTEN MEAL AND LINSEED MEAL. Gluten meal and linseed meal
