Annual Report of the Consulting Chemist. 27^ 



Olive-cake, the residue left in the presses in extractino^ 

 secondary qualities of oil from olives, contains a large proportion 

 of indigestible woody fibre, rather little albuminous matter, and 

 proportions of oil (to which it owes its chief feeding value), 

 which vary considerably in different samples. It rarely contains 

 as much oil as is shown in the preceding analysis. 



The attention of the stock-feeder is directed to the subjoined 

 analysis of a sample of locust-bean meal, lately sent to the 

 Laboratory by a member of the Society. 



The meal contained in 100 parts : — 



Moisture 16"57 



Oil 2-80 



* Albuminous compounds (flesh-forming matters) . . 5 ' 19 



Sugar, mucilage, and digestible fibre (chiefly sugar) 64 • 34 



Woody fibre 7-60 



Mineral matter (ash) 3 • 50 



100-00 

 * Containing nitrogen • 83 



Direct determinations of the amount of sugar in locust-bean 

 meal have shown me that good locust-meal on an average con- 

 tains fully one-half its weight of sugar. It is much relished by 

 all farm-stock ; and, in virtue of the large proportion of sugar 

 which it contains, is very fattening. Locust-meal at present 

 can be purchased in Hull at about 6/. 10s. a ton, and in 

 my judgment is one of the cheapest fattening compounds 

 in the market ; it may be turned to excellent account if 

 it be blended with other feeding stuffs, by selecting especially 

 materials rich in nitrogenous compounds, of which locust-meal 

 is deficient. 



The gentleman who sent me the sample of locust-meal for 

 analysis informs me that he gives, with much advantage, to his 

 feeding cattle, which have been put up for fattening purposes for 

 a few weeks, — 



3 lbs. of locust-meal. 



3 lbs. of best decorticated cotton-cake. 



3 lbs. of Indian corn. 



9 lbs. 



each feed mixed with pulped turnips and cut straw and hay. He 

 reduces the cotton-cake to powder, and also grinds the Indian 

 corn at home into meal, and obtains the mixed meal at a cost of 

 about 8/. 10s. a ton ; and I have no doubt that he makes more 

 money by his fattening stock than he would if, instead of this 

 mixture, he gave them linseed-cake.
