372 FEEDS AND FEEDING 



careful feeder who demands uniformly large results will always keep on 

 hand enough linseed meal, or linseed cake, so it can be used in limited 

 amounts as occasion and necessity demand." 



Due to the fact that linseed meal furnishes slightly less protein than 

 cottonseed meal, it was found to be of slightly lower value than cotton- 

 seed meal as a source of protein in trials at the Pennsylvania, 40 Ver- 

 mont, 41 and North Carolina 42 Stations. Linseed meal tends to produce 

 a soft butter and therefore may sometimes be advantageously fed in 

 rations which would otherwise produce a tallowy product. 



600. Soybeans. Ground soybeans were compared with cottonseed 

 meal in a trial by Price at the Tennessee Station, 43 2.3 Ibs. of these pro- 

 tein-rich supplements being added to a ration of 2.3 Ibs. corn-and-cob 

 meal, 24.1 Ibs. corn silage, and 10.2 Ibs. alfalfa hay. Slightly more milk 

 and butter fat were produced when the ground soybeans were fed than 

 when cottonseed meal was used as the supplement. Likewise at the 

 Massachusetts and New Jersey Stations, 4 * ground soybeans proved 

 slightly superior to cottonseed meal for milk production. 



Otis found at the Kansas Station 45 that when soybeans formed one- 

 half the concentrates, the butter was so soft that it was impossible to 

 work it satisfactorily, even tho chilled with ice water. This can be pre- 

 vented by the addition to the ration of cottonseed meal, which tends 

 to produce hard butter. (256) 



601. Soybean oil meal or cake. Soybean oil meal or cake, the by- 

 product from the extraction of soybean oil, is well-liked by stock. It is 

 about as high in protein as choice cottonseed meal, and the protein is 

 slightly more digestible. Only of recent years has this valuable feed been 

 of any importance in this country, but now considerable amounts are im- 

 ported from the Orient, and oil mills in this country are taking up the 

 crushing of soybeans for oil production. In a trial by McCandlish at the 

 Iowa Station, 46 soybean oil meal containing 43.6 per ct. crude protein 

 was equal in value to high-grade linseed meal, when fed as a supplement 

 to a ration of corn silage, alfalfa hay, and a concentrate mixture of 

 cracked corn, ground oats, and wheat bran. 



In a trial by Gilchrist 47 of England, soybean cake was slightly superior 

 to cottonseed cake for milk production, and in an experiment by Han- 

 sen 48 soybean cake and linseed cake proved practically equal in value. 

 Tho a daily allowance of 4 to 7 Ibs. of soybean cake was fed, no ill effects 

 resulted. Lindsey of the Massachusetts Station 49 found that soybean 

 meal from which the oil had been extracted did not modify the composi- 

 tion of the milk or exert a marked influence on the body of the butter. 

 Feeding soybean oil increased the percentage of fat in the milk tempo- 

 rarily and produced a softer, more yielding butter. (257)
