diet) from 2.97 to 3.27 pounds of dry matter of the feed had snfliced 

 for the production of the same weight of dressed pork (one pound). 

 As it seemed of interest to learn whether the particular course pur- 

 sued in the previously described experiments of feeding skim-milk 

 from the home dair}' with corn meal could be improved on, and, if 

 so, in what direction, the three subsequentl}^ described new feeding 

 experiments were instituted. The principal aim of these new exper- 

 iments was to ascertain, whether a daily diet for pigs, of which skim- 

 milk and corn meal formed a material portion, would secure bet- 

 ter pecuniary returns, in case an exceptionally large xn'oportion of 

 digestible nitrogenous /oocZ-constituent was fed during the entire exper- 

 iment. Gluten meal and wheat bran were chosen for various reasons 

 to serve in the making up of the feed to meet this requirment, as soon as 

 our milk supply became exhausted. A short abstract of the results ob- 

 tained in this connection may be found upon a few succeeding pages. 

 Although not less than four animals have served in each of these three 

 new experiments our present communication will be confined to a de- 

 tailed record of but two animals in each case, with the exception of 

 the last experiment, leaving a more detailed record of a similar char- 

 acter of others to the next annual report. 



THIRD FEEDING EXPERIMENT. 



Four animals of a mixed breed were selected for the work ; their 

 respective weights varied at the beginning of the trial from 40 to 59 

 pounds. The daily diet during the first three months consisted ex- 

 clusively of skim-milk from the Station and of corn meal ; during the 

 remainder of the time (three and a-half months) a mixture of equal 

 weights of wheat bran and gluten meal was added to assist in main- 

 taining the desired close relation between the proportion of digestible 

 nitrogenous and non-nitrogenous food constituents in the daily feed. 

 The relation between these two important groups of food constituents 

 was materially the same during the entire experiment. It consisted 

 of one part of nitrogenous food constituents to from 3.27 to 3.7(1 

 parts of non-nitrogenous constituents. From four and one-half to 

 five ounces of corn meal were added to every quart of skim-milk 

 needed to meet the wants of the animal. This composition of the 

 feed was retained until the quantity called for per head had reached 

 eight quarts of skim-milk and forty ounces of corn meal per day. 

 At this stage of the experiment the mixture of equal weights of 

 wheat bran nnd gluten meal was added to the daily fodder ration ; 

 beginning with sixteen ounces per head, and closing up with twenty- 

 five ounces. The exact amount required per day was governed by 

 the appetite of the animal ; the mixture served to meet the increas- 

 ing demand of the various animals on trial. It is a good rule to in- 

 crease the daily fodder rations only when called for, and always grad- 

 ually. 



The sul)sequent deta,iled record of our results shows that the cost 

 of feed consumed, per pound of dressed weight produced, varied
