10 pounds on the farm-grown ration and gained 69 lbs.. 

 on the ''oil mill ration." With the other two cows there 

 was a slight gain in both periods. 



On an average the coavs on cotton seed lost in weight 

 .8 of a pound per day, while those on the meal and 

 hulls ration, consuming more food, gained .5 of a pound 

 daily. The rations fed during the second experiment 

 were decidedly laxative and the cows showed it in the 

 milk vield and in the loss of live weight. In 1900 the raw 

 cotton seed fed constituted 37.7 per cent of the ''home- 

 grown ration," while in 1901 it constituted 45.50 per cent 

 of the "home-grown rati on.'' 



In 1900 the cotton seed meal fed formed 21.8 per cent 

 of the "oil mill ration'' and in 1901 it formed 27.7 per 



cent. 



The table of live TS'eight shows that in the second 

 experiment all the cows lost in weight when on the 

 farm-oTown ration, while onlv one fell off on the "oil 

 mill ration." The effect of cotton seed and cotton seed 

 meal varied with the different animals, the greatest 

 scouring being with cotton seed. In the first experi- 

 ment Rozena, a very large cow, consumed an 

 average of 8.9 pounds of cotton seed meal daily 

 and appeared Avell in every way, while in the- 

 second period she consumed 9.6 pounds of cotton 

 seed and did not show the effects for three weeks, when- 

 she scoured very heavily and fell off in milk flow. This 

 was undoubtedlv due to the large amount of oil in the 

 cotton seed. In the second experiment Susan, a small 

 heifer, took 6 pounds of cotton seed per day for the first 

 period and appeared at her best during the whole of the 

 month, but six davs after being on cotton seed meal in 

 the second period, getting 6.7 pounds per day, she com- 

 menced to scour and fell off in milk flow. This could 

 not be due to a larger amount of oil in the ration, but
