10 March, 1916.] The Practical Economy of Skim Milk. 165 



The most effective proportion is here proved to be the 1 to 3, when 

 321 lbs. of corn and 585 lbs. of skim milk produced the 100 lbs. of 

 gam. Had the pig^s been confined to the 321 lbs. of grain, the increase 

 (allowing 500 lbs. for 100 lbs. of gain) would be 60 lbs. If limited 

 to the 585 lbs. of skim milk alone, 19i lbs. of gain might be expected. 

 Fed in this way, the total production is 79| lbs. Yet these same 

 amounts, when the pigs were allowed to receive both meal and milk, 

 produced 100 lbs. — a 20-lb. greater return without any extra cost. 

 The improved result should be the common experience of every bacon 

 producer who is fortunate enough to have skim milk, and none should 

 be satisfied with less. 



The Enhancement Effected by Proper Admixture. 



A farmer content to use bare milk gets, from 585 lbs. of skim milk, 

 a return of about 144 lbs. of carcass bacon, which, at 4d. a lb., is worth 

 4s. lOd. ; while another farmer believing in copious pollard can get back 

 all the pollard cost and a further 9s. from the same quantity of skim 

 milk. By spending 16s. for 16 bushels of pollard, to supplement the 

 585 lbs. of skim milk, 75 lbs., or £1 5s., worth of carcass bacon is 

 produced, instead of the 14i lbs. which might be expected from bare 

 milk. Deducting the 16s. for pollard leaves 9s. clear to compare with 

 his sceptical neighbour's 4s. lOd. To get the increased turnover, with 

 its gross money return of £1 5s. instead of 4s. lOd., the farmer certainly 

 had first to lay out 16s. The man who is not willing to spend this 

 is practically accepting 4&. lOd. in preference to 9s. 



What is Lost by not Going Far Enough. 

 So far, the comparison has been between the man who uses no con- 

 centrate and the man who uses it as liberally as it should be used. How 

 does the man fare financially who believes in " some " concentrate only? 

 His ratio is most probably represented in the third experiment in the 

 above tabic. Here the pigs were fed 250 lbs. of concentrate, along 

 with 1,434 lbs. of skim milk — about 1 in 6. The gain was the same, 

 100 lbs., or 75 lbs. of carcass bacon. Therefore, 585 lbs. of milk — 

 the amount used in the best-balanced experiment — and 102 lbs. of 

 concentrate, the same ratio, would produce 30.^ lbs., or 10?. 2d. worth of 

 bacon. From this, 5s. Id. must be deducted fcr the 102 lbs. of pollard. 

 The result is 53. Id. clear. The additional value imparled to skim milk, 

 by proper balancing, is summarized in the following: — 



Milk. Pollard. Bacon Produced. Value. Cost of Pollard. Pmflt. R.'turn per Gallon. 



585 lbs. nil 14.Hb.s. 4s. lOd. nil 4s. lOd. hi. 



585 1b.s. 102 lbs. 30l lbs. 10s. 2d. 5s. Id. 5.s. Id. 1.04d. 



585 lb.s. 321 lbs. 75lbs. £1 5s. IGs. Os. 1.85d. 



"Losing the Ship for a IIaportii o' Tar." 



By laying out 5s. Id. where he .'should lay out 16s., a man t;ets only 

 53. Id. for every 585 lbs. of skim milk (equal to Id. a gallon) instead 

 of 9s. (nearly 2cl. a gallon). Thus 58^ gallons of skim milk may return 

 5s. Id., or 9s., just according to the business capacity of tiie man wiio 

 ha3 the disposal of it. No doubt, the man who gets the fiM-mer rotuni 

 thinks he save.s monev by his more " careful " use of polhird. lie docs 

 save 10s. lid. on the pollard, and receives 143. lOd. less for b^.r-nn
