Aug. i6, 191S Prickly-Pears as a Feed for Dairy Cows 



417 



The prickly-pear used in these experiments contained perhaps more 

 water than the average. Henry (8, p. 572-577) gives the water content 

 of prickly-pear as 84.2 per cent, and Hare's (7) average of several 

 analyses of a certain variety shows these cacti to have 83.41 per cent of 

 water. Prickly-pear containing these percentages of water would be 

 worth probably 50 or 60 per cent more than is last indicated.

o Quantity of hay required to replace 80.84 pounds of prickly-pear= 18.47— 10.37=8.10 pounds. 

 One pound of sorghum hay equals 10 pounds of prickly-pear. 



6 Quantity of digestible nutrients in hay required to replace 4.07 pounds digestible nutrients in prickly- 

 pear is 7.86— 4.75=3.11 pounds. 

 One pound of digestible nutrients in the hay equals 1.31 pounds digestible nutrients in prickly-pear, 

 c One therm in the hay equals 1.70 therms in the prickly-pear.
