EXPEEIMENT STATION RECORD. 



"In these experiments, as in the previous year, no marked advantage resulted 

 from feeding bran. The total gains produced were slightly larger on corn and oats 

 than on corn, and the gains on corn and bran were a little smaller than on corn. 



"The lambs receiving alfalfa, which made the larger gains during the early part 

 of the experiment, continued to make the greater gains during the last weeks of feed- 

 ing, so that the difference grew more marked as the feeding continued. 



"During the last 2 weeks the lots on sorghum ate very poorly, refusing to consume 

 more than IJ lbs. of corn per head daily, except in the case of the lot receiving 16 

 per cent linseed meal with its corn. This lot ate well and made good gains. All 

 lots were thrifty and healthy during the entire experiment. 



Comparative tests of the effect of beet molasses and molasses preparations 

 in animal feeding, K. Gerland {Ber. Physiol. Lab. Lcinrhv. liist. Halle, 3 {1901), 

 No. 15, px). 1-55). — The digestibility of beet-molasses feeds was tested with sheep. 

 For purposes of comparison, digestion experiments were also made with alfalfa hay 

 and with sugar, sufficient asparagin l^eing added to the ration containing the latter 

 to approximate the nonalbuminoid nitrogen content of the molasses. All the mate- 

 rials were fed with a basal ration of alfalfa hay, barley straw, palm nut meal, wheat 

 bran, and brewers' grains, the ration being so made up that it contained per 1,000 

 kg. live weight, about 28 kg. dry matter, 2.4 kg. digestible protein, 0.8 kg. digestible 

 fat, and 13 kg. nitrogen-free extract. The digestibility of the basal ration was also 

 determined. The digestion experiments each covered a period of 10 days and were 

 preceded by a preliminary period of like duration. The food, urine, and feces were 

 analyzed. On the basis of the values obtained for the basil ration and the assump- 

 tion that molasses being liquid is entirely digested, the author calculated the digesti- 

 bility of the basal portion of the ration when fed with molasses and sugar to determine 

 whether the digestibility of other feeding stuffs was increased or diminished by add- 

 ing molasses to the ration. The coefficients of digestibility and these calculated 

 results follow:

o Figures for one animal only. 



The data for the study of the metabolism of nitrogen are reported. As shown by 

 the average results, there was a gain of nitrogen in every experiment, ranging from 

 0.034 gm. on the basal ration to 0.206 gm. on the molasses-maize germ ration. The 

 gains in weight ranged from 0.3 kg. per day on the basal ration to 0.8 kg. per day on 

 the sugar ration. 



The principal conclusions reached follow: With the exception of the cocoa-shell 

 mixture, the molasses and molasses feeds were readily eaten. Unfavorable results
