( pp. T)-!;')). — This is the creamery record for the expei'inients in these 

 two years with milch cows rejjorted in bulletin No. 82. The details 

 are embodied in tables, u.nder the following" headino-s: (1) State- 

 iiient of articles of fodder used: (::! ) Ivecoivl of average quality of 

 milk and of fodder rations: (;>) ^'alue of cream i)roduced. at cream- 

 ei'v basis of valuation: (4) Cost of skim milk at the sellin<2,' price of 

 three cents per cpiart of whole milk; (5) Fertilizing- constituents of 

 cream; ((>) Some conclusions sugg'ested by the records. 



The conclusions drawn include the following- : 



(1) The amount of fat in the milk of the dilferent cows during 

 ]S,s7 varied from 8.45 to 4.50, and averaged 4 per cent ; during 1SS8 it 

 ranged from 8.14 to 4.80, and averaged 8. 97 per cent. 



(•i) The ([uantity of milk, in (juarts. required to produce one space 

 of cream during 1887 varied from iJ.42 to 1.63, and averaged 1.98 

 quarts; during 1888. it varied from 1.98 to 1.48, and averaged 1.72 

 quarts. 



(8) The amount received for one space of cream during 1887 varied 

 from 8 to 8.88 cents, averaging 8.58 cents: during 1888 it varied 

 from 8.25 to 4 cen.ts. averaging 3.72 cents. This is equivalent to 12.17 

 cents pin- quart of cream for 1887 and 12.65 cents for 1888. 



(4) The total cost of feed for the production of one quart of cream 

 amounted for 1887 to 15.09 cents, and for 1888 to 18.55 cents. 



( 5) 'I'he value of the fertilizing constituents lost to the farm by the 

 sale of cream amounted, during both years, to from 2.8 i)er cent to 

 4.5 per cent, or on the average 3.05 per cent of the total fertilizing 

 value of the feed. A loss of 20 per cent of the fertilizing constitu- 

 ents of the feed was' allowed when selling the Avhole milk. 



((i) The net cost of feed (original cost of the feed less the value of 

 fertilizing constituents ()l)tainable in the manure) consumed per 

 quart of cream ( 1 (iuart = 8.4 spaces) averaged for 1887, 8 cents, and 

 for 1888, 6.47 cents. At 12.17 cents per (|uart of cream during 1887 

 and 12.65 cents dui'ing 1888 the profit above net cost of feed was 4.17 

 c^^nts per quart in 1887 and 6.18 cents in 1888. 



(7) "It reipiired on an average during 1887 and 1888. 6.17 quarts 

 of whole milk to ])roduce 1 quart of cream." 



(N) Counting the whole milk at 8 cents per (piart, th(> skim-milk 

 cost on an average during 1888, 1.32 cents per quart. 



The feeding value of slcim milk, containing 9.5 ])er cent of solids.
