Beet residues for farm stock, J. B. Lindsey (Massachusetts 8ta. Rpt. 1909, 

 pt. 2, pp. 21-26). — A discussion of metliods of using dried beet pulp, dried 

 molasses beet pulp, and beet leaves as rations for live stock. An analysis of 

 molasses beet pulp is reported as follovs's: Water 8 per cent, protein 9.5 per 

 cent, fat 0.4 per cent, nitrogen free extract 61.3 per cent, fiber 15.4 per cent, 

 and ash 5.4 per cent. The opinion expressed regarding the feeding value of 

 beet residues may be summarized as follows : 



Dried molasses beet pulp is a very palatable food for dairy stock, and nearly 

 equal to corn meal in its value for such stock. Dried beet pulp has somewhat 

 less value. Their use may occasionally be necessary, but it should be the rule 

 to produce starchy or carbohydrate feeds rather than to purchase them. When 

 used, they should be moistened before feeding. Beet leaves may be fed to dairy 

 stock with fairly satisfactory result.?, either fresh or in the form of silage, but 

 they should not be largely used as food for cows producing milk for infants.

Ration experiments with swine, 1906-1908, W. L. Carlyle and G. E. 

 Morton (Colorado Sta. Bui. 165, pp. 3-23. figs. 2). — Alfalfa hay, wheat, wheat 

 shorts, field peas, beets, and tankage were contrasted as protein supplements 

 for barley and for corn in feeding tests with grade Poland-China swine during 

 2 successive years. The results are summarized in the following table:

The amounts of digestible nutrients required for 100 lbs. gain with the differ- 

 ent rations are also given. There was no advantage in feeding beets in addi- 

 tion to the grain, as the 2 lots so fed ate as much grain as when the beets were 

 not given. Analyses are reported for the barley, durum wheat, tankage, and 

 alfalfa hay used in the tests.
