or per food unit it works out to £4 16s. per ton. Indigestible fibre 

 reaches 10 per cent., or in older samples of ten years ago 28 per cent., 

 which is far too high. As a unit it costs Is. 4d., against 2s. 7d. for 

 cotton-seed meal.

16 and 17. Value of Palm-kernel Oil and Cake. — Palm-kernel 

 cake is sold at 7s. per cwt., and only 10 per cent, of the food ration 

 is given to cows or calves for the first time. 



According to the Oil and Colours Journal, in September 1915 palm- 

 kernel oil was worth £37 10s. per ton first hand, and £48 in March 

 1916. According to this journal it is the lowest priced of all the cakes. 



The price of the cake is £7 to £7 5s. per ton. 



The cake is sold at £7 5s. free on rail per ton at Hull. At the 

 beginning of 1918 it was worth £13 15s. per ton, but in Surrey it could 

 not be obtained under £21 per ton. 



Palm-kernel oil is worth about £40 per ton. 



At the beginning of 1918, palm-kernel oil extracted by solvents 

 was worth £51 per ton ; crushed, £52 per ton ; refined, £67 per ton 

 — which were the official maximum prices. 



17. Uses of Palm-kernel Cake. — Kernels worked by solvents 

 make a more digestible meal — 80 per cent, against 73 per cent, of 

 crushed kernels, and containing 19 per cent, of protein and 2 per cent, 

 of fat, against 18 per cent, of protein and 8 per cent, of fat for crushed 

 kernels. It is used for feeding young pigs and milch cows in Germany. 



18. Results of Feeding Experiments with Kernel Cake. — 

 The weekly gain in live weight with kernel cake ration was 8 lb. at 

 the West of Scotland Agricultural College. The cost worked out at 

 4|d. per lb., and 3 lb. of kernel cake gave better results than 4 lb. of 

 bran. 



At the East of Scotland College, a gain of 2-04 lb. per day was 

 recorded, the cost, being £6 6s. per ton.
