ON FEEDING EXPERIMENTS. 395 



two sows; the former (III.) gave in both lots the best re- 

 sults. The animals were fed alike, in the following way : — 

 One-third of the daily ration of milk was fed with one-half 

 of the daily ration of corn meal at six o'clock, a. m. ; one- 

 third of the milk at twelve o'clock, m., without any meal ; and 

 the remaining third part of milk with one-half of the meal at 

 six o'clock, p. M. Whenever the previous feed was consumed 

 some hours before a succeeding feeding time, the amount of 

 daily fodder was gradually increased. This rule of feeding 

 was carried out during the entire trial and suffered only a 

 temporary modification in consequence of a few short peri- 

 ods of very hot weather. 



At the beginning of the experiment about two ounces of 

 corn meal were fed for every quart of milk, and subsequently 

 three ounces for every quart. This proportion of corn meal 

 to milk produced better results in the case of buttermilk 

 (Lot B) than in the case of skim-milk (Lot A), consid- 

 erino' the lar2;er amount of solid matter contained in the 

 latter. 



Nearly one-fourth of the solid matter noticed in the skim- 

 I milk shows no return of a proportionate increase in live 

 weight, as will be found on comparing the subsequent de- 

 tailed record. The total live weiijht and dressed weii>ht of 

 both lots of animals differ only two to four pounds from each 

 other, — the buttermilk leading. The cost of fodder per 

 pound of dressed pork produced, amounts in Lot A (skim- 

 milk) to 5.8 cents, and in case of Lot B (buttermilk; to 

 4.6 cents. 



This difference in cost corresponds quite closely with the 

 difference in cost of the two kinds of milk. The dressed 

 pork was sold at 7^ cents per pound. The value of manure 

 produced will be reported on some later occasion, when 

 actual values can be presented. 



The investigation is continued. Two breeds — Berkshire 

 and Chester — are already on trial to' turn to account the 

 information received in the first experiment.
