meals of other leguminous seeds are highly nitrog- 

 enous and are indicated as valuable materials 

 for balancing rations which contain a large amount 

 of succulent material with a comparatively low 

 percentage of protein. Among the various milling 



Products which have been used for milk production 

 rewer's grains and distiller's grains occupy impor- 

 tant places. These materials are being fed more 

 and more until at present it is difficult to obtain 

 them at the brewery since they are contracted for 

 long periods in advance. Brewer's grains are 

 rather more nitrogenous than the whole barley 

 since a part of the starch is changed into sugar and 

 fermented out in the manufacture of beer. They 

 may be used in rations of thirteen to fourteen 

 pounds with excellent results. It requires about 

 four pounds of wet grains to equal one pound of the 

 dried grains. Some difference of opinion has pre- 

 vailed regarding the effect of brewer's and distil- 

 ler's grains on milk and butter. When used in 

 rations of average size there appears to be no seri- 

 ous objection against them on this score. In Mas- 

 sachusetts, brewer's grains have been found some- 

 what more effective than wheat bran. Malt 

 sprouts, another of the products of brewing, are 

 about equal to gluten meal in feeding value. Reg- 

 ular distiller's alcohol grains have been found to be 

 very effective in producing milk, while the rye 

 grains are somewhat less valuable. Distiller's 

 grains, when compared with cotton seed meal, were 

 found to be somewhat more costly than the latter, 

 but the percentage of fat in the milk was increased 

 while the quality of the butter was slightly inferior 

 to that produced by cotton seed meal. 



Cotton seed meal is universally recognized as one of 

 the most effective nitrogenous feeding stuffs whether
