FEEDING ADJUNCTS 173 



The crude fibre in the absorbent base is estimated 

 by the ordinary method. 



{U) Molasses. — 10 grams of the material are extracted 

 with warm water as in {a), and the residue collected in a 

 Gooch crucible, dried, and weighed. The solution is 

 diluted to 100 c.c, and of this 10 c.c. (equal to i gram 

 of the feed) is evaporated for moisture estimation, as in 

 170 {a). The molasses in the remainder of the solution 

 may be examined, if desired, by the processes described 

 above (170). 



Condiments, etc. 



172. Precipitated Phosphate of Lime. 



This material is sometimes used, under various 

 names, as an adjunct to feeding stuffs. 



The material should be examined qualitatively for 

 arsenic and soluble calcium salts and the citrate soluble 

 phosphate estimated as in 124 (^), p. 136. Ninety per 

 cent, of the phosphate present should be soluble in citric 

 acid or ammonium citrate. This will detect sophistica- 

 tion with bone meal or bone ash, which can only be 

 assimilated to the extent of 13-14 per cent, by the 

 animal, as against 50-60 per cent, of the true precipitated 

 phosphate of lime. 



173. Spices^ Cattle Powders^ etc. 



Appetisers, conditioning powders, etc., are largely 

 placed on the market. For an examination of the 

 condiments one must rely largely on the sense of smell 

 and the detection of such substances as fennel, aniseed, 

 locust bean, fenugreek, gentian root, etc., of which they 

 are very frequently composed. 



Cattle powders sometimes consist merely of common 

 salt, bicarbonate of soda, Glauber's salts, powdered 

 charcoal or sulphur, and such like substances, mixed
