Tlie following table shows the coefficients of digestibility of the 

 various nutrients and the balance of income and outgo of nitrogen in 

 the 5 dietary studies : 



Analyses of feeding stuffs, M. Weibull (TidsJcr. LandtmUn, 17 

 (1896), pp. 294-299). — The report is published as the fifth number of 

 Contributions from Alnarp Laboratory, and gives analyses and discus- 

 sions of concentrated feeding stuffs examined by the author during 

 189o-'9<>. The following results show the range in the constituents of 

 24 samples of wheat bran analyzed during the year : 



Analyses of wheat bran. 



The samples examined were classified according to their quality, as 

 follows: Good, 61 per cent; average, 17; poor, 17; very poor, 5 per 

 cent. The faults of the latter 2 classes were: Goods old or improperly 

 handled, as shown by musty odor, a high degree of rancidity, and the 

 presence in abundance of insects, molds, or fuugi; or, adulteration of 

 bran of inferior quality, oat hulls, weed seeds, screenings, or sand. 

 The maximum content of sand found was 9.82 per cent. This sample 

 also contained a large number of fungi and whole weed seeds, calcu- 

 lated to be at least 1,500,000 per 100 kg. The author recommends the 

 practice of giving a rebate in case of bran containing a high content of 

 weed seeds, on a scale similar to that adopted in the Province of Ehine- 

 Prussia and Saxony, viz : 



In case of a content of 10,000 to 20,000 weed seeds per 100 kg., 1 per cent discount; 

 in case of a content of 20,000 to 40,000 weed seeds per 100 kg., 2 per cent discount; 

 in case of a content of 40,000 to 60,000 weed seeds per 100 kg., 3 per cent discount. 



Analyses of samples of rape-seed cakes, beet molasses, molasses feed, 

 "cattle bread," and blood molasses, are also given in the article, and the 

 value of the different feeds discussed. — f. w. woll.
