FOODS ANIMAL PRODUCTION. 173 



shire, with 2 lots of 10 sheep each, to compare dried distillery grains 

 and Harburg linseed cake. The test began January 1, 1895, and lasted 

 62 days. Both lots were fed turnips, and in addition one lot received 



I lb. per head per day of distillery grains and the other lot the same 

 quantity of linseed cake. The composition and cost of the feeding 

 stuffs is given. 



The lot fed distillery grains gained on an average 2§ lbs. per head 

 more than the lot fed linseed cake. The slice]) were slaughtered and 

 the amounts of carcass and tallow recorded. The carcasses of the 

 grain-fed lot were the heavier. The cake was more expensive than the 

 distillery grains. 



"The grain-fed lot made most progress during the first month and 

 the cake-fed lot did the best during the second. It is probable that if 

 the experiment had lasted another month the cake-fed lot would have 

 made up on the others." 



Experiments on the comparative value of beet diffusion resi- 

 due silage and Tankard fodder beets, 1'. Ga.y and E. Fle {Ann. 

 Agron., 23 {1897), Wo. 4, pp. 115-169).— -The relative value of beet dif- 

 fusion residue silage and fodder beets is discussed, and analyses are 

 given of the fresh diffusion residue and of the silage. 



Experiments to test the relative feeding value of this silage and 

 fodder beets were made with sheep and a milch cow. Ten Dyshley- 

 Meriuo sheep were divided into 2 uniform lots of 5 each, weighing 250 

 lbs. and 268 lbs., respectively. The test consisted of 2 periods sepa- 

 rated by 4 days. The first period began January 14, 1896, and covered 

 14 days. It was preceded by a short preliminary period. Both lots 

 were fed a basal ration of 500 gm. field peas, 500 gm. oat straw, and 24 

 gin. wheat chaff per head daily. In addition lot 1 received 3 kg. of 

 Tankard fodder beets, and lot 2 4.5 kg. of beet diffusion residue silage. 

 The rations for the two lots contained practically the same amount of dry 

 matter and nutritive ingredients. Lot 1 gained 19.5 kg. audlot 2 11.5 kg. 



The second period began January 5 and lasted 13 days. The same 

 basal ration was fed as during the first period. In addition lot 1 was 

 given the silage and lot 2 the fodder beets. At the beginning of the 

 period the lots weighed 264 kg. and 280.5 kg., respectively. Lot 1 lost 

 5 kg. and lot 2 2 kg. During the whole test there was a difference of 



II kg. in favor of the silage. 



The relative value of these two articles for milk production was tested 

 with a milch cow. She was fed a ration of 3.8 kg. of hay, 975 gm. of 

 middlings, 2 kg. of oat straw, and 45 kg. of beets; and during 7 days 

 the amount and composition of the milk was determined. Afterwards 

 the silage was gradually substituted for beets until 60 kg. per clay was 

 consumed. This quantity of silage contained the same amount of dry 

 matter as 45 kg. of beets. During 7 days the amount and composition 

 of the milk was again determined. 



The principal conclusions reached were the following: Taking into
