Commercial feeding stuffs, E. G. Peoulx et al. (Indiana Ftn. liul. tit 

 (1918), pp. 3-152). — This bulletin contains the usual data regarding the In- 

 diana feedings stuffs control law and its enforcement, Including a discussion of 

 the findings in the Inspection during the year. Analyses are reported of wheat 

 bran, wheat middlings, shorts, red dog flour, low-grade flour, rye middlings, 

 buckwheat hulls, alfalfa meal, blood meal, meat scrap, meat meal, tankage, 

 dried beet pulp, coconut-oil meal, corn bran, gluten feed, gluten meal, hominy 

 feed, velvet bean feed, cottonseed feed, cottonseed meal, cold pressed cotton 

 seed, brewers' grains, distillers' grains, yeast grains, linseed meal, and proprie- 

 tary and mixed fee 



New feeds, a. J. Patter [Michigan Bta., Quart. /?»/., 1 {1918), No. 1. pp. 15. 

 16). — Brief descriptions of the following feeds which have appeared recently to 

 a greater or li enl on the markets are given: Barley f l. oatmeal by- 

 products, corn feed meal, corn bran, corn oil cake meal, velvet bean f l, and 



rye feed. The description iii some instances Includes the gross composition. 



[Analyses of feeding stuffs], C. I" B8KBBE ( inn. Agr. Sui»8e, /.'' (1918), No. 

 1. pp. 116-119). — Analyses are reported of samples of feeding stuffs,* Including 



press cakes same, peanuts, corn, and flaxs l; cereal flours; and fodder 



mixtures of various materials. 



Synthetic capacity of the mammary gland. — I. Can this gland synthesize 

 lysin? i: B. Bast, v. B. Nelson, and w. Prn [Jour. Biol Chem., 86 {1918), 



No. ..'. pp. 291-801 in Jour. Amer. Ked. h . 7f {1919), Ho. /. 



p. 70). — Feeding experiments similar to those of Osborne, Mendel, and Ferry 

 (B. S. Et., 28, p. 864), in which glladin was u- basal protein, have been 



conducted by the authors with rats as experimental animals and Sein as the 

 basal protein. 



The results indicate that it is very probable that the mammary gland has 

 not the capacity to synthesize lysin. and that lysin lg not dispensable for normal 



maintenance. The evidence |s considered to support the view that, as far as 

 the proteins are considered, milk Becretion, like growth, is ultimately dependent 



Upon the quality and quantity of amino adds Ingested with the food.

 tests with pasture grasses for cattle are briefly described. On two acres ,,f 



mixed grasses planted in June. 1917, and including in the seed mixture 2 lbs, 



alslke clover, 2 lbs. meadow- fescue, 7 lbs. brome - lbs. oat gn — B Lbs. 



orchard ;t;ks ^ lhs. rye L r r,i^. and •"• lbs. Kentucky blue i.'r;i^. per acre, all 

 varieties, except possibly Kentucky blut . made n rank g r ow th the lir-t 



year. The field produced some hay and was used for fall pasture. In another 



• a mixed irrass pasture had made sufficient growth for pasturing by May l 



and continued to supply pasture until in October. It was estimated that on 



this pasture one and one-half acres would have provided continuous ; 

 sufficient for two cows. 



r - on sweet clover pasture were fed ii daily ration of 10} ]|is. of rolled 

 barley for four weeks, when during the next four weeks 1 lb. of tankage -• 



Substituted for 1 11>. of the grain. At the em] of this period the tankage WU 

 Increased to 1* lhs. daily. The quantity of prain per pound of gain was re- 

 duced from 8.68 lhs. when no tankage was fed to 2 :i u.s.. Including the tank 

 when this was added to the ration. In 1917 pigs on a '_* per cent u'rain ration 

 required per pound of gain ."..1 lbs. of feed when on sweet .lover pasture, while 



pigs on alfalfa pasture required B.6 n>-. in 1916, however, pigs on alfalfa 

 pasture required only 2.4 lbs. of feed to produce l lb. of pain. The results of 

 a feeding test indicated com t.> i.e more economical than barley for fattening 

 plga when the price per pound is the same, a comparison of hand r and
