feeding tests. The basal ration consisted of grain, hay, and straw. The gains 

 made corresponded very closely with the relative percentages of dry matter in 

 the roots. 



[Experiments with alfalfa hay and alfalfa silage], S. C. Dinsmore {Ne- 

 vada Sta. Bui. 73, pix 37-/fO). — In digestion experiments with sheep the average 

 digestion coefficients were as follows: Alfalfa hay, dry matter 57.93, protein 

 G1.77, fat 40.07, fiber 54.06, nitrogen-free extract 67.75, and ash 35.68 per cent; 

 alfalfa silage, dry matter 46.55, protein 54.63, fat 79.80, fiber 39.16, nitrogen-free 

 extract 42.92, and ash 44.87 per cent. 



Wine-residue molasses, O. Fallada {Osterr. TJngar. Ztschr. Zuckerindus. u. 

 Lwndw., 3D (1910), No. 3, pp. J/Ol-JflO). — Chemical analyses are reported of a 

 feed composed of a mixture of molasses and the residue from the wine press. 



Calcium carbonate for the preservation of molasses feeds, O. voN Czadek 

 (Ztschr. Landio. Versuchsw. Osterr., 13 {1910), No. 6, pp. 591-596). — A series of 

 tests to determine the effect on the keeping quality of molasses feeds of adding 

 calcium carbonate. 



The results show that feed thus treated lost in feeding value, that the con- 

 serving effect of calcium carbonate is very slight, and that with controls kept 

 for 8 mouths there was no apparent advantage over the usual method of storage 

 in thus treating the feed. 



Results of the feed inspection for 1910, B. E. Curry and T. O. Smith 

 (New Hampshire Sta. Bui. 149, pp. 10). — ^Analyses are reported of alfalfa 

 meal, hominy feed, cotton-seed meal, brewers and distillers' grains, gluten feeds, 

 molasses feeds, beef scrap, poultry, and miscellaneous feeds. The present state 

 law to protect the consumers of commercial feeding stuffs is characterized as 

 inadequate. 



TJniform commercial feeding stuffs law (Amer. Hay, Flour, and Feed Jour., 

 18 (1910), No. 1, pp. 26, 27).— This is the draft of a proposed uniform feeding 

 stuff law which was adopted by the Association of Feed Control Officials, 

 November, 1910. 



[Feeding experiments in 1909], J. H. Grisdale, R. Robertson, J, Murray, 

 A. Mackay, and G. H. Hutton {Canada Expt. Farms Rpts. 1910, pp. 62, 63, 

 79-103, 329, 330, 361-311, Jfl9, J,20, 488, 489, pi. i).— In a horse feeding test it 

 was found that corn and bran 5 : 2 or barley and bran 5 : 2 could be substituted 

 for oats and bran in the same proportions, although both the corn and barley 

 were less palatable than the oat ration. 



Three lots of lambs were fed a basal ration of " nutted oil cake," bran, oats, 

 and hay. With turnips as a supplementary feed the gain per head and day 

 was 0.244 lb., at a cost of 10 cts. per pound; with ensilage as a supplementary 

 feed the corresponding gain was 0.244 lb., at a cost of 9 cts. per pound; with 

 both turnips and ensilage the gain was 0.21 lb. per head and day, at a cost of 

 10.9 cts. 



In swine feeding tests the cost per pound of gain on a ration of shorts, 

 ground oats, feed flour, bran, roots, and skim milk was less than on a ration of 

 corn and barley. Preliminary notes are given of an experiment in the ventila- 

 tion of piggeries. Pork production was cheaper when wintering swine in the 

 open than when confined in pens. The open lots, however, were provided with 

 cabins for sleeping. 



Seven short fed 2-year-old steers in 117 days made an average daily gain 

 per steer of 2.12 lbs., at a cost of 6.33 cts. per pound. Three " carried over " 

 steers in 290 days made an average daily gain per head of 1.32 lbs., at a cost of 

 11.68 cts. per pound. Three long fed steers in 990 days made an average daily 

 gain per head of 1.2 lbs., at a cost of 7.1 cts. per pound. Five baby beef steers
