need to be considered. This may be collected in various 

 ways as follows: 



By keeping the pig in a small pen which has a smooth 

 floor where the droppings can be gathered without much 

 waste. The objections to this method are that if the at- 

 tendant is not preseitt at all times the pig may get a con- 

 siderable portion of the droppings on his feet and body 

 and more or less of it may be lost. Also the solid matter 

 may become mixed with the urine which would detract 

 somewhat from the results obtained. 



Pigs may be kept in small comfortable pens and have 

 bags attached to them to catch the droppings as they 

 are voided. In such cases barrows should be used in or- 

 der that the urine will not interfere. This bag if properly 

 arranged aiifords an opportunity to save practically all the 

 feces that are voided. However, a pig that is put into 

 such a harness is more or less under abnormal conditions 

 and cannot be expected to do normal work, at least for a 

 considerable length of time during which he is becoming 

 accustomed to this apparatus. 



A pig may also be kept in a crate which is just large 

 enough for him to stand up or lie down in conveniently. 

 In such a case barrows are also used and the crate is so 

 arranged that the urine runs forward at least to the center 

 of the crate. The solid excrement falls at the rear end 

 and may be gathered without much difficulty. The ob- 

 jection to this is that the pig must necessarily be confined 

 to a very small place, which again is not normal, or is 

 not the same condition that is usually afforded to pigs in 

 the process of pork production. The results obtained in 

 such close confinement, therefore, cannot be said to apply 

 directly to conditions that are more nearly in accordance 

 with nature.
