ANIMAL PEODUCTION. 



Concentrated feeding stuffs, L. A. Voorhees and J. P. Street {New Jersei/ Stas. 

 Bui. 160, pp. 79, Jigs. .?). — In aci-ordance witli the provinions of the State Feeding 

 Stuffs Law, a large number of samples of feeding stuffs were analyzed, including 

 (.-otton-seed meal, linseed meal, cocoanut cake, germ-oil meal, gluten meal, gluten 

 feeds, hominy meal, and similar corn breakfast food by-products, corn bran (or sugar 

 feed), malt sprouts, dried brewers' grains, dried distillers' grains, mixed feeds 

 (including cereal breakfast food by-products), rice meal, calf meal, ground meat, 

 poultry feeds, wheat bran (from winter, s])ring, and unclassified Avheat), wheat feed, 

 wheat middlings, brown middlings, feeding flour, buckwheat bran, buckwheat feed, 

 rye bran, rye middlings, rye feed, barley feed, corn meal, cob meal, ground corn and 

 oats, and other mixed ground grains, flaxseed meal, wheat bran and oil, sugar-beet 

 pul]), and nutrium milk powder. 



"Of the 287 samples which were guaranteed and of which an examination was 

 made, 76 failed in their promises, 60 of these being deficient in protein. Among the 

 249 samples of feeds not required to be guaranteed, 14 were found to be contaminated 

 or adulterated with foreign matter, principally offal of milling. 



"There are on the feed market a considerable number of very inferior feeds, which 

 consist of oat hulls, rice hulls, coffee hulls, etc., which can not form a profitable pur- 

 chase at any price. In buying feeds to supplement his home-grown supply, the 

 dairyman's aim shcuid bo to secure digestible and palatable protein on the most 

 reasonable terms and in the mo.st economical forms. Fully half of the different and 

 distinct brands of feeds [analyzed] do not meet his requirements in this respect." 



Descriptions are given of rice hulls and coffee hulls, which the authors state are 

 new adulterants in the feeding stuffs sold in New Jersey. 



The losses in the fat of corn meal due to the action of molds were studied. On the 

 basSis of a large numl)er of analyses the fat in normal corn meal was found to average 

 in amount 47 per cent as much as the protein. Samples which showed under the 

 microscope the presence of Feriicilium glaucum had lost from 4.2 to 67.7 per cent of 

 the fat which should have been present if the meals were originally of normal quality. 

 To determine whether the growth of mold was the real cause of the diminished fat 

 content, samples of normal corn meal of known composition were inoculated with P. 

 glaucum and the mold allowed to grow" for 9 days at an average of 71° F. under differ- 

 ent conditions as regards moisture. The percentage loss of fat was found to range 

 from 1.85 to 12.24, the smallest loss being found in the sample in which there was 

 10.7;! per cent of water present and the greatest in the sample having the largest 

 amount of water, viz, 36.24 per cent. In other words, the percentage loss of fat 

 increases with the amount of moisture ])resent. Other tests are very briefly reported, 

 which bear out tills ojjinion. 



The composition of the commercial feeding stuffs sold in Connecticut, 

 E. H. Jenkins et al ( Conneclicut State Sta. Rpt. 1901, pt. 4, pp. 813-349) .—During the 

 year 1901 a number of feeding stuffs were analyzed, in accordance with the provi- 

 sions of the State law. These included cotton-seed meal, linseed meal (old and new 

 process), bran, middlings, mixed wheat feeds, corn meal, gluten meal, gluten feeds, 

 hominy feeds, rye feed, malt sprouts, buckwheat shucks, buckwheat middlings, com- 

 mercial and proprietary feeds (including cereal breakfast food by-product«), animal 

 meal, beef scrap (and similar poultry feeds), and several condimental and medicinal 

 feeds. A table showing the weight per quart of a numV)er of commercial feeds is 

 also given.
