DESCRIPTION OF FEEDING-STUFFS 203 



to diminish the amount of fat in the milk, and also 

 to affect, adversely, the taste, colour, and ease with 

 which the cream is separated. In any case 2 Ibs. per 

 head per day is quite enough for cows. Poppy- 

 seed cake is not very durable. 



Hemp cake. The waste products from the hemp 

 which come into commerce as cake or meals are 

 often badly adulterated with leaves, stems, sand, 

 and earth. The extraction of the oil has also to 

 take place at a high temperature, so the cakes are 

 often burnt, and on account of the moisture which 

 they take up tend to become mouldy. Hemp cake, 

 like poppy cake, is credited with containing poison- 

 ous substances, so that it is advisable to restrict the 

 use of it to grown male animals. Good undamaged 

 hemp cake is a suitable food for working horses, which 

 may be given 3 Ibs. per day, fattening cattle can stand 

 5 Ibs., and fattening sheep up to i Ib. ; cows also 

 ought not to get more than i Ib. per head per day. 



The following residues from oil works occasionally 

 come into the market, but generally only in small 

 quantities. 



Beech-nut cake, the properties of which closely 

 resemble those of the unpressed beech mast (p. 190). 



The seeds of False flax (Camelina sativa) are 

 sometimes made into cake, which has an acrid, un- 

 palatable taste, resembling onions and mustard. It 

 flavours the milk, butter, and even the flesh un- 

 pleasantly, and is said to cause abortion.
