ANIMAL PRODUCTION. 



Animal breeding- and feeding- investigations by the Bureau of Animal 

 Industry. I>. E. Salmon i U. S. Dept. Agr. Yearbook, 1904, pp. 527-538, pi. I).— 

 The investigations undertaken under the auspices of the Bureau of Animal Industry 

 in breeding sheep, poultry, and horses, the studies of animal nutrition, and of 

 beef and pork production under southern conditions are described, and plan- for 

 future work outlined. A considerable proportion of the work referred to has been 

 undertaken in cooperation with agricultural experiment stations. 



Fodders and feeding stuffs, F. T. Sin it i Canada Expt. Farms Rpts. 1904, pp. 

 166-182). — Analyses are reported of fodder corn grown in hills and drills, including 

 dent ami flint varieties, rape, rape Bi'lage, rape and corn Bilage, mangels, carrots, turnips, 

 and sugar beets, linseed cake, gluten feed, cotton-seed meal, "Uveco" and "Flaker- 

 ine" (both made apparently by flaking steamed or partially cooked [ndian coin;. 

 meat meals for poultry, pea meal, pea dust, ground pea bran, barley feed, meal seeds, 

 oat dust, spoiled raisins I \\ ith a view to learning their value as poultry feed . ground 

 seeds (largely weed seeds, screenings, etc. I, and a commercial mixed d-al. 



The percentage composition of the rape silage was: Water 78.19, protein 2.67, tat 

 0.84, nitrogen free extract 12.93, crude fiber 2.00, and ash 3.37; and of rape and corn 

 silage 1 :1. water 79.66, protein 2.18, Eal 0.37, nitrogen-free extract 10.40, crude fiber 

 5.29, and ash 2.10. 



The rape silage contained 1.36 per cent albuminoid and 1.31 percent non-albumi- 

 noid nitrogen; the rape and corn silage L.04 and 1.14 per cent, and the rape 1.30 and 

 0.61 per cent, respectively. 



"The observed increase in the non-albuminoids and the concomitant decrease in 

 the albuminoids that has followed upon ensiling the rape marks the most important 

 change in the composition of the dry matter of the rape. This in conjunction with 

 the destructiou of a part of the carbohydrates necessarily increases the percentages 

 of the fiber and ash. The changes are such as might have been expected and indi- 

 cate a certain deterioration in the silo of the dry matter of the rape." 



Commercial feeding stuffs ( Connecticut Sim, Sta, Rpt. inn',, pt. 5, pp. 885- I

Commercial feeding stuffs, J. L. Hills, C. H. Jones, and K. M. Hollisteb 

 i Vermont Sta. /.'"/. 109, pp. 8). — Under the provisions of the state feeding stuff law. 

 a number of samples were examined, including cotton-seed meal, linseed meal, gluten 

 meals and irc<\-. dried distillers' grains, oat feeds, hominy chop and similar goods, 

 provenders (corn and oat products), and wheat offals. 



In discussing the feeding stuffs sold in the State, the results of live year.-' work are 

 taken into account. "No material change in the average grade of the richer con- 

 centrates [now sold] appears, save in the gluten meals. This improvement, how- 

 ever, is due to an alteration in a manufacturer's pro. ess rather than t<> any direct 

 effect of inspection. The by-products of the oatmeal mills have been quite decidedly 

 upgraded, and farmers are less inclined than formerly to regard a liberal Bhowing 

 of oat hulls in a provender as a guaranty of excellence." As in past years, some of 

 the corn and oat provenders contained too large a percentage of oat hull-. 



Regarding the success which has followed the passing of a feeding stuff law. the 



authors state that "live years ago guaranties were few and far between. To-day 

 they are in general use, and. while too often disregarded, or. indeed, misinterpreted, 

 they are at once protective ami educative." 



The data presented in a comparison of the amount of protein furnished by differ- 

 ent classes of concentrated feeds, as compared with their cost. shows that cotton-ea d, 

 linseed, and gluten meals, and dried distillers' grains rank highest and Low-grade oat 

 feeds lowest of the materials considered.
