140 AMERICAN DAIRYING. 



Taking the average result of the above six calves fed 

 skim-milk, 15,6 lbs. skim-milk produced a gain of 1 lb. live 

 weight. 



Will it pay to feed calves simply skim-milk as has been 

 done in the above examples? The six calves consumed 9,345 

 lbs. of skim-milk to make a gain of 598 lbs. This increased 

 gain in this locality would sell for five cents a pound , or 

 $29.90. The milk drank, estimating its market value at 15 

 cents per 100 lbs., would cost $14.02, showing, a difference of 

 $15.88. 



The writer believes that a still greater gain would have 

 been made by these calves if the fat removed from the milk 

 had been replaced by flaxseed or some other substitute. 



Taking the growth of these six calves — 598 

 lbs., worth 5 cents per pound — we have $29.90 

 to be credited to the 9,345 lbs. of skim-milk, 

 which is 32 cents per 100 lbs. 



Mississippi station work.— Tiie Mississippi 

 Experiment Station (report of 1888, page 43) 

 found that calves receiving 10 lbs. of skim-milk 

 made nearly as large gains as those receiving 8 

 lbs. of whole milk. 



Iowa station work.— The Iowa Experiment 

 Station in "Bulletin No. 14" reports the cost of 

 producing a pound of gain (estimating new 

 milk at 87 cents per 100 lbs., skim-milk at 15 

 cents per 100 lbs., grain at 1 cent per pound, 

 hay at $5 per ton, and flaxseed-meal at ^ cents 

 per pound) was 7.6 cents for the fresh milk and 

 5 cents for the skim-milk ration. 



Pennsylvania station work.— The annual 

 report of the Pennsylvania State College for 

 1891 gives the results of work done with whole
