These experiments were conducted for periods long enough to show 



conclusively that prickly-pear is a good and palatable feed for dairy 



cows. It is best to feed the plant in medium quantities, 60 to 75 pounds 



a day to each cow. When fed in large amounts, 1 20 to 1 50 pounds a day, 



it causes an excessive scouring and a very insanitary condition of the 



stable. On account of the high content of mineral matter, it is thought 



that prickly-pear may be of special value as a supplementary feed for 



use with other roughages of a low mineral-matter content, such as 



cottonseed hulls.
