46 Molasses and Dairy Cows. 



and an account of these later tests is furnished by Herren E. 

 Raram and C. Momsen to the Milch Zeitung of 14th July, 

 1900. In this case the salts, other than sugar, in the 

 molasses were supplied to the cows as an addition to the raw 

 sugar in the form of the "refuse" [Melasseschlenipe) left after 

 molasses had undergone treatment to free it from the sugar 

 remaining therein. The chemical constituents of the 

 molasses and refuse were as follows : —

The ash contained about 51*27 per cent, carbonate of potash,. 

 23*40 per cent, carbonate of soda, 17*51 per cent, chloride of 

 potassium, 6*53 per cent, sulphate of potash, and 0-40 per 

 cent, phosphate of potash. 



Five cows were selected, and in the case of each 

 two-thirds of the period of lactation had elapsed. The 

 experiment commenced on the 15th April, 1900, and 

 was divided into four periods of twelve, nine, twelve?- 

 and fourteen days respectively, the results being 

 deduced from weighings, milk yields, etc., taken on the last 

 four days of each period. Throughout the whole time the- 

 cows received (per 100 lbs. live weight) 1 lb. of hay, 0*225 l° s - 

 of straw, 5 lbs. of mangolds, and 0*3 lbs. of ground-nut meal. 

 In addition they received, in the first period, o*6 lbs. of 

 molasses ; in the second, 0*264 1DS - of sugar [t.e. y the amount of 

 sugar contained in o*6 lbs. of molasses) ; in the third, 0*35 lbs* 

 of "refuse," in addition to the 0*264 lbs. °f sugar. This refuse 

 contained as much nitrogenous organic matter as the o*6 lbs. 

 molasses, so that this ration was almost the same as the first. 

 In the fourth period the same ration as at first — viz., o*6 lbs. 

 of molasses -—was again given, so as to permit of a calculation- 

 being made to eliminate the influence of lactation. 



The chief results are exhibited in the following table. 

 The calculations per 1,000 lbs. of live weight have all been 

 made on the initial average weight — viz., 998*632 lbs. 

 The correction for lactation has been made by assuming
