be from $3.30 to $4 at the brewery, to which the cost of cartage 

 should be added. Four tons of wet grains contain nutritive 

 material equivalent to that found in 1 ton of dry grains, or in 

 1.1 tons wheat bran, or in ^ ton gluten feed. With these data 

 at hand, the i)urchaser of this material can calculate at what 

 price he can secure an equal amount of nutrients in the various 

 dry feedstutfs. The writer has not had an}' experience in feed- 

 ing wet grains, but believes that !25 pounds is a fair allowance 

 daily for average-sized cows.^ In addition, 2 to 4 pounds of 

 dry grain may be fed daily, such as a mixture of equal parts by 

 weight of (1) mixed wheat feed and gluten feed, (2) wheat 

 bran and fine middling.-^, or (3) wheat bran and com meal. 



The succulency of the wet grains is a factor not to be over- 

 looked in estimating the value of the feed. It is not believed 

 that the brewers' wet gi-ains are an objectionable feedstuff when 

 fed in a fresh condition and in moderate (piantities. It must 

 be remembered, however, that they are likely to sjwil easily, 

 excepting when the temperature is low, and the partly decom- 

 posed grains would not be considered suitable for producing 

 first-class milk. "When milk is intended for the use of infants, 

 young children or invalids, it is better not to use the wet grains. 



C. Malt Sprouts. 

 (a) ^Iciluul of Prcjmi-afion. 

 ]\Ialt used in the manufacture of beer is prepared by mois- 

 tening barley and allowing it to sprout in a warm atmosphere, 

 thus ]u'oducing a ferment called dia.stase, which readily con- 

 \-('rts starch into sugar. After the sprouting process has con- 

 tinued a number of days, the barley is dried, the sprouts re- 

 moved by machinery and sold for cattle feed ; each 100 pounds 

 of malted barley yields about 4 pounds of s])routs. Sprouts of 

 fir.st quality are about Vi of nu imli long, thread-like in appear- 

 nuce, slightly curled, of a yellow or of a brownish yellow 

 color, and form a cris]), porous and bulky mass. ^Mixed with 

 the sprouts one often notes more or less malted barley kernels, 



' It is understood that 50 or more pounds are frequently fed daily. It is believed, however, 

 that the sm.aller quantity is preferable when the grains are fed continuously, and it is desired to 

 retain the same animals in the herd from year to year.
