The utilization of Para rubber seed {Bui. Imp. Inst. [So. Kemington], 11 

 (1D13), Xo. J,, pp. 551-6.'')9; obs. in Agr. Bitl. Fed. Malay f<tates, 2 (1014). No. 8, 

 pp. 213-215). — Sheep and cattle feeding experiments with Para rubber seed cake 

 are reported. 



All attempts at feeding sheep with the cake failed. Cattle ate it readily but 

 when the quantity was increa.sed to 8 lbs. per head daily scouring occurred. 

 With dairy cattle fed on Para rubber seed cake the yield of milk rose, but the 

 percentage of milk fat remained unchanged. 



The composition of the cake is given as follows: Moisture 8.7n per cent, 

 protein 80.19, fat 8.71, carbohydrates 41.71, crude fiber 5.01, ash 5.6 per cent, 

 and feed units 139. A small quantity of cyanogenetic glucosid was present, 

 yielding approximately 0.02 per cent prussic acid, a negligible quantity. 



Studies on the nutritive requirements for fattening mature cattle and 

 sheep.- — Feeding' experiments with heated liquid potato distillery refuse and 

 with dried refuse in comparison with palm-nut cake, W. Voltz. J. Paeciitner. 

 A. Bavdrexel, W. Dietrich, and A. Deutschland (Landw. .Jahrb., 45 {1913), 

 No. 3, pp. 325-437, pis. S, fig. 1). — Analyses of malt sprouts, dried brewers' 

 grains, potato flakes, potato refuse from distilleries, and palm-nut cake are re- 

 ported. The water-free potato refu.se contained 25.47 per cent of protein, 0.68 

 fat. 53.15 nitrogen-free extract. 6.94 crude fiber, and 13.76 ash. 



Two lots of 5 head each of yearling Hampshire wethers were fed during a 

 164-day feeding period on a basal ration consisting of millet hay, oat straw, 

 malt sprouts, brewers' grains, and iwtato flakes; lot 1 receiving potato refuse 

 and lot 2 palin-nut cake. During the last 45 days of the period molasses was 

 added to both rations. The total increase in weight per head for lot 1 was 15.26 

 kg. and for lot 2, 18.16 kg. ; the dry substance consumed per head per day by 

 lot 1, 1,072.2 gm. and lot 2, 1,075.1 gm. ; and the estimated starch value required 

 per kilogram of grain 5.22 kg. for lot 1, and 4.59 kg. for lot 2. The dressing 

 percentage was 51.2 and 50.2 per cent, and the intestinal fat 2.3 and 1.85 per 

 cent, respectively. 



It Is concluded that feeding stuffs have a specific value independent of their 

 starch value, and that molasses added to the ration has a speoiflc value in In- 

 creasing the nutritive value of the ration for sheep and cattle.
