1920.] Feeding Stuffs in September. 581 



There is greater choice of feeding stuffs on the market than 

 there was some time ago. English beans and peas, buckwheat 

 and rye are now quoted. 



Undecorticated Cotton Cake. — It is satisfactory to notice that 

 the cake likely to be in most immediate demand, namely, un- 

 decorticated cotton-seed cake, at .£12 10s. per ton, provides 

 starch equivalent at the reasonable price of less than 2Jd. per Lb. 

 At this price it will probably be widely used for milch cows at 

 grass. It is specially suitable for this purpose as its astringent 

 properties prevent scouring when the grass becomes watery in 

 the early autumn. 



Palm-Kernel Meal for Pigs. — Since last month Messrs. 

 Mackenzie and Fleming have issued, under the title of Modern 

 Pig Keeping, a pamphlet which describes the results of many 

 pig-feeding trials carried out at Cambridge between 1917 and the 

 present time. Their trials have demonstrated the suitability of 

 palm-kernel meal for all kinds of pigs when used under proper 

 conditions* For young growing pigs it should be supplemented 

 with dried blood or some similar product, for fattening pigs with 

 maize meal or some other starchy fat-producing food. Copies 

 of the pamphlet can be obtained for the cost of postage from the 

 Secretary, School of Agriculture, Cambridge. Pig keepers will 

 find the use of palm-kernel meal most economical, as it provides 

 starch equivalent at less than ljd. per lb. as compared with 3d. 

 or more in the case of most cereal meals. 



Dried Blood. — Manufacturers of feeding stuffs appear to be 

 turning their attention to the preparation of suitable samples of 

 dried blood. Foods of this kind, which are prepared from animal 

 products, require great care in their manufacture. If prepared 

 from the blood or offals of diseased animals they are liable to* 

 transmit disease. If not properly dried they will not keep. 

 When prepared with proper care, it seems likely that they may 

 be very useful additions to cereal or other meals as sources of 

 protein and of accessory food factors or vit amines. 



Fish Meal is another feeding stuff of this kind, but its manu- 

 facture has now been standardised. Formerly all kinds of fish 

 refuse were dried together and sold as the evil-smelling product 

 known as fish guano. In this form it could only be used for 

 manure. The fish refuse is now carefully selected. Some of i< 

 is still used for making fish guano, but the better stuff is steamed, 

 extracted, dried and ground to a meal, which lias little smell,
