if they are fed alone iu larjie ([uantities (above 3 qts. daily) or fed in combination 

 with other material of a similar nature, the tendency is to cloy the appetite of the ani- 

 mal, or — in warm weather especially — to produce iuHanimatiou of the milk glands. 

 "In a daily grain ration of 9 lbs. we would not advise feeding over 3 or 4 lbs. of 

 but one by-product having above 7 to 8 per cent of fat." 



Chicago gluten meal vs. Atlas meal, J. B. Lindsey et al. {Massa- 

 chusetts Hatch iSta. Bpt. 18!J'), pp. L^ol, 23:2). — An experiment to compare 

 Chicago gluten meal and Atlas meal was made with 4 grade cows. It 

 was preceded by a preliminary test of 7 days and was divided into 2 

 periods of 10 days each. In the first period 2 cows were fed 4 lbs. of 

 Chicago gluten meal and 2 others 4 lbs. of Atlas meal daily. During 

 the second period the feed was reversed. In addition each cow received 

 4 lbs. of wheat bran, 5 lbs. of hay, and about 40 lbs. of coru-and-soja 

 bean silage throughout tlie experiment. The composition of Chicago 

 gluten meal and Atlas meal is given, and the results are expressed in 

 tabular form. 



"The cost and quantity of milk and butter fat are so nearly equal in each case as 

 to be considered practically identical. If the quality of the Atlas meal is maintained, 

 it can be regarded as an excellent food for milch cows and neat stock in general." 



Soiling experiments with leguminous and cereal crops, C. S. 

 Phelps [Connecticut Storrs Sta. Ept. 1895, pp. 77-92). — This is a con- 

 tinuation of work previously reported in Bulletin 9 of the station 

 (E. S. E., 4, p. 479). The object of the test was to compare the relative 

 feeding value of green fodders high in protein with those low in protein. 



Six ordinary grade cows bought from farms or from the college herd 

 were divided into 2 lots of animals as nearly alike in yield of milk and 

 butter fat as possible. Eight tests were made. The green fodders 

 experimented with were as follows: Oats and peas, soja beans, clover 

 rowen, cowpeas, rowen grass, barley and i^eas, oat fodder, Hungarian 

 grass, and corn fodder. The quantities fed were 80 lbs. of corn fodder 

 and 70 lbs. of the other fodders per head daily. The green fodders 

 were usually cut and hauled to the stable every other day. 



At the beginning of each feeding test both lots were fed on a legu- 

 minous ration during a preliminary period of 5 days. After this, lot 2 

 was fed a ration of cereal fodder, while lot 1 received the same ration 

 as at first. These rations were fed for 2 weeks. The exj)eriment proper 

 covered only the last 9 days. At the close of the experiment each 

 lot was fed a ration similar to that used in the preliminary test. 



The digestibility of the green fodders was determined in experiments 

 with sheep, reported on page 422, since it was more convenient to make 

 digestion experiments with sheep than with cows. The amount of 

 digestible nutrients and fuel value of the rations fed per cow per day 

 were computed from the results of these digestion experiments. 



Tables are given which show the yield and comjiosition of the milk of 

 'each cow for each period.
