The winter-grazed steers made the greatest total gain for the winter 

 and summer periods combined, as was the case during the first three 

 years' work. The rations of Lots 1, 2, and 3 are not directly com- 

 parable to the lots wintered on harvested crops during the first three 

 years' work. 



GRAPHIC PRESENTATION OF LOSSES AND GAINS. 



The comparative rapidity and extent of gains and losses can be 

 showm more clearly by the use of a chart, figure i), than in any 

 other way. It shows the average changes in w^eight of the steers of 

 the four lots. 



The average length of the total period for three 3'ears w'as 266 days, 

 of wdiich 126 da3"s were in the winter, or feeding, period, and the re- 

 maining 140 in the summer, or grass, period. The heavy, black, 

 vertical line near the center of the chart marks the dividing line be- 

 tween the w^intcr and summer periods. The other vertical lines rep- 

 resent 28-day. periods wdth the exception of the last period during the 

 winter, w^hich was only 14 days. The horizontal lines on the chart 

 represent pounds of gain or losses, as the case may be. The diagonal 

 lines representing the various lots of cattle show losses in weight 

 when they go downward and gains in weight when they go upward. 

 Lt will be noted that during the winter period all the lots lost con- 

 siderable weight during the first 28 days, and, excepting the last 14 

 days, the two silage-fed lots lost more than the others. During the 

 second, third, and fourth months all the lots lost quite uniformly
