" ['Nutriotoue'] contains a considerable quantity of some leguminous seed, some 

 linseed meal, and perhaps otlier feeding' stuflts, together with aromatic substances 

 (fenugreek, aniseed, caraway, and the like), and over 10 per cent of salt. The 

 analysis shows its value in a general way as a feed. The material, however, is 

 claimed to be rather in the nature of a tonic having medicinal properties than of a 

 feeding stuff, as is judged from the fact that the prescribed dose for cattle is 2 table- 

 spoonfuls with each feed. " 



The market price and the vahiation are given for all the feeding 

 stufls analyzed except the wheat hay and rye hay. The vahiation is 

 calcnhited on the basis of protein at 2.3 cts., nitrogen -free extract and 

 fiber at 0.04 ct., and fat at 1.14 cts. per ]»ound, which was found to be 

 the cost of these materials in the concentrated feeding stuffs examined. 



On the composition and digestibility of the nitrogen-free 

 extract of corn fodders and of pasture grass, W. Fkear and W. 

 S. tSwEETSEK {rcnnsylraiiia Sta. Bpt. 1892^ pi). 41-50). — The glucose, 

 sucrose, starch, and residual extract in the nitrogen- free extract of 

 sweet-corn fodder, dent-coru fodder, and pasture grass were deter- 

 mined, and the digestibility of these was determined in experiments 

 with sheep and steers. The average compositions of the nitrogen-free 

 extracts were as follows:

The coefficients of digestibility found were as follows:

"The starch of corn fodder, in general, is found to be more digestible than that of 

 the grasses examined by .Jordan, as is also that of the pasture grass, though in the 

 latter case a different species of herbivora was nsed in the experiment. 



"The residual extract of the sweet corn is more digestible than that of the dent 

 samples, though the average digestibility of this portion of the total extract is not 

 far from that fouud by Jordan in the cases of grasses and clovers,"
