ANIMAL PRODUCTION. 1153 



A parallelism may be noted between fat cleavage (saponification) and fat 

 resorption, and the jjreater the cleavage the greater the resori)tion. Fat withont 

 I lie addition of otlier food stnffs is well assimilated by the body, the proportion 

 ri'sorbed being abont 0(j per cent in the case of butter and beef fat. Lard is 

 somewhat less thoroughly assimilated, probably owing to its laxative properties. 



'IMie expeiMments i'ei)orted were made with dogs having operative fistulje. 



The effect of training upon the muscular power with isometric work, 

 A. F. IlKi.i.sTKN (Sh-aiid. Arch. PhiiHioL, J!) (1907), No. 1-3, pp. 218-230).— Yrom 

 investigations with young men In training for a boat race, the author concludes 

 that in order to obtain the maximmn effort from a muscle or group of nuisdes 

 the power of coordination must be develoju'd. The relation of this power to 

 fatigue and related matters are spoken of. Fatigue manifests itself more slowly 

 with trained than with untrained muscles.

Feeding stuff inspection, ('. 1). Woods and J. ^L Barti.ett (Maine Sta. Bui. 

 1)2. II p. !)3-ll.'i). — ^The feeding stuffs examined under the pi'ovisions of the State 

 law included cotton-seed meal, cotton-seed feed, linseed meal, gluten feed and 

 meal, distillers' grains, brewers' grains, alfalfa meal, proprietar.v feeds, molasses 

 .•md sugar feeds, corn and oat feeds, oat feeds, homin.y feeds, miscellaneous 

 starchy feeds, wheat offals, and beef scraps. Most of the feeding stuffs met, 

 or very nearly met, their guarantee. 



" The cotton-seed meal .situation has been a very unfortunate one in Maine 

 the present .vear. In the late fall the cotton crop was very seriously damaged 

 by a storm wliich resulted in a smaller yield of cotton seed than was anticipated, 

 and also made considerable dark-colored meal. This shortage materially ad- 

 \anced the price of choice cotton-seed meal and increased the quantity of meal 

 that was below prime in quality." 



Many feeding stuff's composed of refuse from milling oats, corn, etc., are on 

 the market. "For the most part these goods are fairly well up to their guar- 

 antee and no fault can be found with the manufacturer for desiring to sell 

 these waste products. Vew or no claims are made for nutrients which the goods 

 do not actually carry." 



Though many of the corn and oat feeds meet their guarantee this was not the 

 case with some of the corn and oat feeds and mixed feeds. " There is no class 

 of feeding stuffs in which the consumer needs to use greater care at present than 

 in the i)urclinse of mixed feeds. While the regular brands are all right, as 

 they have lieen in the past, there are some spurious articles in the market." 

 Ai)i)arently fraud was intended with only one brand of wheat offals. 



As regards I)eef scraps it was pointed out that the guarantee placed on the 

 goods is in some instances at least only a very general guide to their actual 

 composition. 



Stall feeding versus grazing, A. M. Soile and J. It. Fain (Virf/inia f>ta. 

 liiil. II! 'i, pii. -ll-SS, fi(/s. 11). — Tests were made to compare the cost and possible 

 Iirofits of fattening cattle in stalls with feeding a low grain ration through the 

 winter in stalls and finishing on grass. 



In the test with stall-fed cattle, which covered ISO days. (5 lots of 8 steers each 

 were used. It was also a part of the i)lan to study the comparative value of 

 different corn produ<-ts wlieii U'd witli cotton-seed meal and so the grain ration, 

 which averaged (J.T li>s. per head i)er day at the beginning of the test, was made 

 nil of ear corn, split corn, fine corn-and-cob meal, and coarse corn-and-cob meal 

 each with cotton-seed meal 1 : 1, and shelled corn and corn meal each with 

 cotton-seed me.il about 2:'\. The coarse fodder in every case consisted of corn 

 silage, hay. and corn stover. As the test progressed the amount of grain and
