ANIMAL PBODUCTION. 903 



nance ration, the author concludes that 0.04 to 0.05 gm. phosphoric acid per kilo- 

 gram of weight is necessary for a maintenance ration, an amount which would be 

 supplied by the foods making up an ordinary maintenance ration. A little more 

 than half of'the quantity siiL."_ r i'stcil is excreted in tin- mini-. The requirements of 

 infants, as regards phosphoric acid, arc also considered. 



The minimum amount of sulphur excreted in the urine and the minimum 

 amount required in a maintenance ration, E. Maurel (Compt. Rend. Soc. Biol. 

 [Paris'], 56 {1904), -V"- ^7, pp. 796 798). Continuing his investigations, the author 

 studied the sulphur requirements of the body and came to the conclusion that 0.025 

 t(. 0.03 gm. per kilogram of weight was sufficient foran adult, which quantities would 

 be furnished in the usual amounts of ordinary foods which would make up a main- 

 tenance ration.

ANIMAL PRODUCTION. 



Commercial feeding stuffs now in the Connecticut market ( ( 'onneclicut StaU 

 5i!a. Bui. 1/7, pp. 55). — In carrying out the provisions of the State feeding stuff law 

 analyses were made of a number of samples of cotton-seed meal, linseed meal, old 

 and new process, bran, middlings, and mixed feed from winter and spring wheat, 

 corn meal, corn flour, gluten meal and feed, hominy feed, rye feed and bran, malt 

 sprouts, dried distillers' grains, dried brewers' grains, ground oats and feed, buck- 

 wheat middlings, provenders and mixed feeds; proprietary horse, dairy stock, and 

 poultry feeds; animal meal and bone for poultry, apple pomace, and dried molasses 

 beet pulp. 



In connection with the chemical analyses microscopical examinations were made. 

 In most cases the feeding stuffs were of the required quality. Analyses showed that 

 2 samples of mixed feeds were spurious since they contained ground corncobs in 

 addition to the wheat products which should make up this class of goods. From a 

 summary of the analytical data obtained during several years regarding winter and 

 spring wheat products the following general conclusions were drawn: 



"The spring wheat products, as a rule, have somewhat higher percentages, both 

 of protein and fat, than the winter wheat products. 



"This difference is rather more pronounced and constant in the case of middlings 

 than in that of either bran or mixed feed. 



"The percentages of protein in bran are rather lower than in either middlings or 

 mixed feed. 



"On the average the winter wheat products sell at a slightly higher price than the 

 spring wheat products in spite of the higher protein and fat content of the latter. 



"The percentages of protein in all the wheat feeds have been considerably lower 

 in 1904 than in either of the three years immediately preceding. The prices have, 

 however, ruled higher." 



As regards apple pomace, the opinion is expressed that this material is "well 

 worth housing and feeding to cattle." The experience of a practical feeder is quoted 

 who has fed it to both horses and cattle with good results.
