EXPERIMENT STATION RECORD. 



MuLLNEK {Landw. Vers. Stat., 81 (1913), ^'o. 3-6, pp. 205-288). — Experiments 

 conducted in feeding wheat and rye products to stieep and swine resulted in the 

 following estimated coefficients of digestibility: 



DigestibiUty of wheat and rye products hy sheep and s-wine. 



It is estimated that the rye sprouts contained 21.23 per cent of digestible 

 protein and 75.8 per cent starch; wheat sprouts 21.97 per cent digestible pro- 

 tein and 74.7 per cent starch. The percentage of weed seeds was also estimated 

 and their germinating strength determined. 



The general conclusions reached were that rye and wheat sprouts are pro- 

 tein-rich and highly digestible for both sheep and swine; and that the meals 

 of rye and w^heat vary in digestibility according to the degree of grinding, the 

 coarser meals invariably being the more digestible. 



Digestibility experiments with, sheep. — Para rubber seed cake, S. J.,M. 

 AuLD (Jour. Agr. Sci. [Englajid], 5 {1913), No. 4, pp. 429-433) .—The product 

 used in these experiments is the press cake left after expression of the oil from 

 the kernels of the seed of the Para rubber tree. It was thought that the press 

 cake might be dangerous for use as a cattle feed owing to the high content of 

 rrussic acid in the seed but the cake was found to be free of this acid. The 

 composition of the cake is given as follows : Moisture 9.27, protein 29.84, ether 

 extract 20.11, nitrogen-free extract 83.08, crude fiber 3.15, and ash 4.55 per cent. 



The average coefficients of digestibility of the Para rubber seed cake as de- 

 termined by several sheep-feeding experiments were as follows: Protein 90.09, 

 ether extract 97.2, nitrogen-free extract 95.3, and crude fiber 100 per cent. 

 These would make it one of the most digestible concentrated feeds available. 



reeding experiments with cattle and sheep, 1902—1913, D. A. Gilchrist 

 (County NorthumJ). Ed. Com. Bui. 20 (1913), pp. 46). — In this bulletin former 

 experiments (E. S. R., 26, p. 767) are summarized and the experiments for 

 1911-1913 given in detail. 



It is concluded that the results from feeding an equal amount of dry matter 

 in yellow turnips and in swedes to store cattle during the winter months are 

 very similar. 



The advantage of box feeding of cattle over stall feeding was found to be 

 considerable. Cattle wintered out of doors showed the best gains at the end 

 of the winter period, but slightly lower gains during the spring and summer 

 Iteriods than those that had been wintered indoors. 



Comparing swedes, yellow turnips, and no roots for fattening sheep the re- 

 sults were slightly in favor of swedes. Sheep fed outside made decidedly 

 lower gains than those fed inside. Bullocks made somewhat greater gains 

 than heifers, although heifers fed in box stalls made better gains than the bul- 

 locks in stalls. Results indicated practically no advantage from linseed cake
