Tests with Feeding Stuffs.

The table shows that when 3.5 lbs. of rye meal was substituted for 

 an equal weight of corn meal in the ration the milk flow and fat 

 ;ydeld decreased. We may conclude that rye meal is somewhat less 

 valuable than corn meal for the dairy cow. (177) 



626. Oats V. wheat bran. — Woll of the Wisconsin Station^ com- 

 pared ground oats with wheat bran in a feeding trial with 4 cows 

 lasting 47 days with the results shown in the table : 



The table shows a return of about 11 per et. more milk and fat 

 from ground oats than from wheat bran. The high feeding value 

 of oats for the dairy cow is well illustrated in this trial. However, 

 because of the high price this grain now commands, most dairymen 

 cannot afford to use it in any large way. 



Hills of the Vermont Station- found that oat feed was about as 

 valuable as equal parts of bran and corn meal for dairy cows. (169) 



627. Emmer. — Wilson and Skinner of the South Dakota Station,^ 

 when feeding brome hay and corn silage for roughage, found that 

 cows produced 1 lb. of butter fat for each 15.5 lbs. of corn or barley 

 meal fed, while 17.5 lbs. of ground emmer (speltz) were required, a 

 difference of 13 per ct. in favor of barley or corn meal. (178) 



628. Kafir meal. — In a trial with 18 cows for 7 weeks, Cottrell 

 and Skinner of the Kansas Station* found that 8 lbs. of kafir meal and 

 20 lbs. of alfalfa hay made the cheapest dairy ration for Kansas con- 

 ditions. Wben fed with prairie, timothy, or sorghum hay or corn 

 fodder, kafir tends to dry up the cows, and if fed abundantly to 

 fatten them. (183) 



629. Sorghum meal. — During three 20-day periods Cook of the 

 New Jersey Station^ fed cows rations composed of 5 lbs. corn stover, 

 20 lbs. brewers' grains, 5 lbs. wheat bran, and 9 lbs. of either sorghum
