1). (pp. !)l-n2). — AA'hen exi)eiinn'nts in ]V\<x fee<lin.ii' w<'re eoinnience(l in 

 1SS4:, the question jnoposcd for stmly was as to tlie most ])i()titahle utili- 

 zation of skim milk and buttermilk. In the ex])eriments on this sub- 

 ject two eomlitions have been eonsidered, (1) a larji-e sn]ii)ly <»f either 

 sU im milk or buttermilk, and (2) a limited one. 



Ill (-(Uisiderinj? the first condition, the i)lan has l»ecii tu mixcorn meal 

 w itli the skim milk or Imttermilk in the lollowinii' jiroportiuns: 



Live weiprht of auinial: 



20 to 70 ponnds 2 onncos corn meal per qnart of milk. 



70 to 130 ])onnds 4 ounces corn meal per quart of milk. 



130 to 200 i)ouuds 6 ounces ctun meal per quart of milk. 



Where the supply of buttermilk and skim milk has been limited, the 

 milk has becMi supplemented by the followinu' iiiain mixtures extended 

 with water: 



The aim has been untler both conditions to feed rations ]ia\in«i" the 

 followiny," nutritive ratios: ^\'ith i)i.us weiiihinii' from I'O t(» 7t> pounds, 

 1 : L'.S to 1 : ;>: with those weiji'hin;; from 70 to I'M) ])onnds. 1 : .'>.(» to 1:4; 

 and with those weif;hing" from I'M) to IMH) pounds, 1 : 4.."> to 1 :.">. 



From .Alay, ISSi, to {September, 1880, ten separatt^ exi)eriments were 

 made, in which 57 pigs were used. The average results of each of these 

 <'xperimeuts are given in the following summary, which is taken fiom the 

 report. The pecuniary results are calculated on the basis of corn meal 

 at 824, barley meal at 830, corn-and-cob meal at 820.70, and wheat 

 bran and gluten meal each at 822. .")0 per ton; butteiniilk at l.">7 cents, 

 and skim milk at 1.8 cents ])er gallon; and by <ledu<-ting 70]»er cent of 

 the estimated value of the fertilizing ingredients of the food to deter- 

 mine the net cost.
