ANIMAL PEODTJCTION. 



Inspection of feeding stuffs {Ncio York mate Bta. Bill. 303, pp. 203-25.'t).— 

 Of 297 samples of -"-otton-seed meal, linseed meal, gluten feed, corn bran, dried 

 distillers' grains, malt sprouts, dried brewers' grains, hominy feed, barley and 

 oat by-products, beet-sugar wastes, meat meals and other animal products, 

 poultry foods, and other feeding stuffs analyzed, 28 were materially below 

 gnarauty, which is 41 less than the number found a year ago. Tables of 

 analyses are given. 



" With reference to the proprietary feeds, not only have the percentages of 

 protein, fat, and fiber been determined, but these mixtures have been studied 

 with reference to the ingredients from which they were compounded. This 

 was done by a microscopic examination of 38 brands. 



" Nearly all of these compounded feeds contain either oat hulls greatly in 

 excess of what belong to the ground oats present, or ground corncobs. 



" The molasses feeds . . . nearly all contained a great variety of weed seeds, 

 some of which are noxious weeds such as mustard, charlock, wild carrot, and 

 English plantain (narrow-leaved plantain, buckhorn). Germination tests show 

 that in several cases these seeds have uot lost the power of germination." 



It is stated that these weed seeds have an unknown nutritive value and that 

 many pass through the animals undigested, thus becoming a menace not only 

 to the land but also to the productiveness of the animals which receive a 

 smaller quantity of digestible nutrients than has been assumed by the feeder 

 who buys these feeding stuffs for pure sound grains. 



Twelve gluten feeds examined for acids and artificial coloring matter were 

 found to have a total acidity equivalent to from 0.09 to 0.91 per cent hydro- 

 chloric acid. Sulphuric acid was present only in traces, except in one sample 

 which showed 0.18 per cent of SO3. The acidity was much higher in the 7 

 samples found ai-tificially colored and it is suggested that the acids may be 

 added to fix the coloring matter. 



reed stuffs, R. E. Rose (Fla. Quart. Bui. Dept. Agr., 18 {1908), No. 1, pp. 

 17-21, 36-39, 96-121).— According to the results of 223 analyses, "the general 

 average of all the commercial feed sold in the State was slightly above the 

 guaranty." The valuation of feeding stuffs and related questions are spoken of. 



The materials examined included bran, middlings, shorts, mill feefl, ship 

 stuff, ground ear corn, hominy feed, cotton-seed meal, cotton-seed hulls, gluten 

 feed, cocoanut meal, commercial or proprietary feeds, sugar or molasses feeds, 

 beet pulp, commercial poultry feeds. Natal grass hay, and Japanese Kudzoo 

 vine hay. 



The composition of Natal grass hay was as follows : Protein 7.45, fat 1.80, 

 nitrogen-free extract 39.23, crude fiber 36.75, aud ash 5.02 per cent, and of 

 Japanese Kudzoo vine hay — protein 10.59, fat 1.68, nitrogen -free extract 32.81, 

 crude fiber 40.09, and ash 8.83 per cent.
