30 days, a small amount of corn being fed to counteract any laxative effect. 

 The cows rejected the tougher vines.*' " Probably the best way to pasture the 

 plant would be to start in early spring when the first growth begins, and graze 

 enough to prevent development of any large woody vines, the young .shoots being 

 very tender and well liked by the cattle." 



It was al.so found that the chopped kudzu vines compared favorably with 

 com or soy l)eans as a soiling crop for dairy cows. 



Pasture trials, M. J. Thompson (Minnesota Sta., Rpt. Duluth Substa., 1918- 

 19, pp. 22-24)- — Continuing work previously noted (E. S. R., 39, p. 474), prog- 

 ress reports on the use of cut-over stump land and pasture are presente<l. 



In 1918 the fourth and final test of a project to study the butter fat producing 

 value of the pasture was conducte<l. Three cows gra/.ed five acres for 3.9 

 months, day and night, and produced 33G.4 lbs. of butter fat valued at .$ir)3.0G. 

 .\bout 140 lbs. of grain valued at $26.60 were fed. There was an average gain 

 in weight of 43 lbs. per head. 



In 191S six heifers gained 175 lbs. per head during a pasture season of 129 

 days, and in 1919 eight heifers averaged 172 lbs. gain in 146 days. In 1918 

 and 1919 six horses were on pasture from June to September except during 

 their working hours. In 1918 they increased somewhat in weight and in 1919 

 maintained their weight. Substantial saving in hay and labor by this method 

 of management is noted. 



Broom millet seed as feed for stock, H. Wenholz (A(;r. Gaz. N. S. Wales, 

 SI (1920), No. 5, pp. S05-307).— The author reports that the grain shortage in 

 New South Wales following a recent drought has resulted in the extensive 

 use of broom corn ("broom millet") seed as a feed for live stock, particularly 

 poultry. The seeds are fed whole to chickens and sheep, ground for horses 

 and cattle, and soaked in water or skim milk for hogs. The seeds must be 

 stored in a well ventilated barn to prevent heating. 



Fish meal as stock food (Live Stock Jour. [Londofi], 92 (1920), No. 2JflJ^, 

 pp. 5i>, 57). — Cases are cited of the successful use of fish meal in calf feeding 

 at Kilmarnock (E. S. R., 41, p. 572) and elsewhere. It is stated that British 

 manufacturers have agreed to put on the market a " white fish meal " having 

 a nunimum of 55 per cent protein and a maximum of 5 per cent oil. It will 

 contain not more than 4 per cent salt nor less than 16 per cent of lime phosphate. 



Sugar in oat straw and cattle foods, S. H. Collins and A. Spiller (Jour. 

 Soc. Chein. Indus., 39 (1920), No. 5, p. G6T). — The authors report that oat 

 straw cut green may have a sugar content in excess of 6 per cent (mostly in- 

 vert sugar), wliile fully mature straw contains practically no sugar. Peanut 

 cake contained 8.46 per cent of sugar and palm kernel cake 3.05 per cent; in 

 neither case was there more than a trace of invert sugar. A knowledge of the 

 sugar content of feeds is considered important, so that results secured with 

 ordinary feeds rich in sugar will not be ascribed to the sugar in any condi- 

 mental feeds that may also have been fed. 



Feeds with public formulas, E. S. Savage (Cornell Countryman, 16 (1919), 

 No. 2, pp. 71-73, 90, 92, 9-',, 96, fig. i).— At the time of writing there were being 

 .sold three ready-mixed dairy feeds compounded according to uonsecrct formulas 

 furnished by the New York State College of Agriculture, and formulas had 

 been suggested for two other feeds not yet marketed. The State Grange and 

 Ihe Dairymen's League were active in initiating the project. 



Analyses of commercial feeding stulls and registrations for 1920, C. S. 

 Cathcaut (Neio Jersey Stas. Bui. 3.',2 (1920), pp. 5-62).— The report is made on 

 826 samples of feeding stuffs collected under the State law in 1919. Data as 

 13621°— 20 6
