 Third Experiment. (See Table III.) 



In determining the cost of the rations in these tests, cot- 

 ton seed was rated at 12 1 cents per bushel, separated milk 

 at 5 cents per gallon and whole milk at 20 cents per gallon. 

 It was our aim to make the entire test with separated 

 milk and cotton seed, but owing to unavoidable circum- 

 stances whole milk was substituted for separated milk. It 

 is very evident that whole milk at 20 cents per gallon can 

 not be fed to pigs with profit. 



At two periods during the test these pigs were slightly 

 affected, but at no time were they seriously ill. 



Pig No. I, from July 15 to September 2, received daily 6 

 lbs. of separated milk and 3.^ lbs. of cruyhed cotton seed. 

 "With the average weight of the pig at 108 lbs., the nutritive 

 ratio is 1: 5.1. The pig gained 11^ lbs. at a cost of 21| cents 

 per lb. On August 15 this pig did not eat cotton seed and 

 was evidently somewhat sick. 



Pig No. I, from September 2 to October 21 (49 days), re- 

 ceived daily 6 lbs. of whole milk and 3| lbs. of crushed cot- 

 ton seed. With the average weight of the pig at 126 lbs., 

 the nutritive ratio is 1:6. The pig gained 19 lbs. at a cost 

 41 1-3 cents per lb. On September 19 this pig failed 

 to eat the cotton seed and was slightly ill. 



Pig No. II, from July 15 to September 2, received daily 6 

 lbs. of separated milk and 3^ lbs. of crushed cotton seed. 

 With the average weight of the pig at 90 lbs., the nutritive 

 ratio is 1:5.8. The pig gained 12| lbs. in 49 days at a cost 

 of 20 cents per lb. On August 15 this pig ate very little 

 cotton seed. 



Pig No. II, from September 2 to October 21, received daily 

 6 lbs. of whole milk and 3^ lbs. of crushed cotton seed. 

 With the average weight of the pig at 100 lbs., the nutritive 

 ratio is 1:5.7. The pig gained 8 lbs. in 49 days at a cost of 

 98 cents per lb. On September 19th, this pig refused to eat 

 cotton seed.
