MA^E STATE COLLEGE 



April 29th to May 29tli is compared with May oOthto June 27th. 



A part of Period 2 is left out of consideratiou, as it seems 

 more accurate to compare closely contiguous periods of time. 

 Period 4^ is not mentioned, as during part of July the animals 

 were so harassed by flies that their growth must have been greatly 

 affected. 



There can be seen below the weights of hay and ensilage eaten, 

 both total and digestible, and the gain made by each animal during 

 each period. The grain eaten is not stated, as it was the same in 

 the periods compared. 



As has already been shown the digestibility of the ensilage was 

 determined by actual trials, as was also that of the hay fed from 

 Jan. 4th to Feb. 2od, it being the Early and Late Cut Timothy, the 

 composition and digestibility of which are given on pages 44 and 

 45 of this report. The hay fed during the other periods, was that 

 cut during the first of the ha3'ing season, and was mostly Timo- 

 thy, and so its digestibility is assumed to be the same as Early 

 Cut Timothy grown the same year and harvested at nearly the 

 same time. A description of the steers used in this experiment, 

 with a fuller statement of their rations, weights, etc., will be found 

 later. The data given in this connection are only a part of an ex- 

 periment covering more than a year's time, the object of which was 

 to compare the growth of different breeds, and only such facts are 

 now stated as are needed for showing the effect of changing part 

 of a hay ration for corn ensilage,

* The hay is assumed to have 83 per cent, of organic matter throughout. 

 t The weights of the Steers were found by averaging their weighings made 

 on three consecutive days.
