A germination test of unground grain screenings after digestion showed tl:;it 

 more weed seeds \^-ere destroyed by passing tlirough the digestive tract of a cow 

 than of a horse. 



Maintenance tests with a pig, mule, and bull were also made of oat hulls. 



Silver beet feeding- tests at Belfast freezing- works, A. Macpiierson {Jour. 

 Agr. [New Zeal.], 6 {IDJS). No. 2, p. 165). — From experiments in foraging sheo]) 

 on silver beets at intervals during a season of 10 months, it was concluded that 

 the carrying capacity per acre was 8.28 sheep for 70 dr.ys. The crop was 

 greedily eaten and the sheep thrived upon it. 



Value of sugar beet tops, Bachelieb {Sucr. Indig. et Colon., 81 (1913), 

 No. 21, pp. 488, 489). — Sugar beet tops and pulp when fed as silage were found 

 to be very palatable, nourishing, and comparatively cheap. Analyses of the 

 tops and pulp are given showing a high percentage of carbohydrates.

Feeds, and how to judge them by the guarantied analysis, J. H. Page and 

 R. M. HuTCHiNS (Bur. Mines, Manfrs. and Agr. [Ark.], Bui. 3, 1913, pp. Uf). — 

 The various feeding stuffs are defined and their guarantied analyses considered. 



Feeding- experiments, Gerlach (Mitt. Kaiser Wilhelms Inst. Landw. Brom- 

 berg, 5 (1912), No. 1, pp. IS, 19). — In tests to determine the relative value of 

 protein for growth, 25 pigs were fed a ration of potatoes, meat meal, rape, and 

 barley. Lot 1 received 4 kg. and lot 2. 3 kg. of digestible protein per day per 

 1.000 kg. live weight, and the average daily gains were 0.519 kg. and 0.516 kg. 

 per head, respectively. 



Two lots of steers were fed chopped straw, potatoes, rice meal, cotton-seed 

 meal, and rye. Lot 1 received 2.5 kg. and lot 2, 1.8 kg. of digestible protein.
