FIFTEENTH ANNUAL YEAR BOOK— PART X 711 



(b) Rotation of hog pastures and lots is easily and cheaply brought 

 about, thus avoiding parasitic infestation, internal by worms (round, 

 thorn-headed, tape, lung, pin, and others), and external by lice and 

 mange). 



(c) A proportionately greater amount of light may enter if the 

 roof doors are fitted with sash lights as in the Iowa Movable Hog House. 



(d) A more thorough airing and lighting is possible in that the roof 

 doors, gable windows, sides, and general door may all contribute. These 

 openings have an area which is proportionately greater in relation to 

 the capacity than those in the centralized. It may be possible in the 

 large type to provide as great a proportionate area of windows and doors, 

 but hardly practicable. 



(e) Floors are likely to be more dry and sanitary because the manure, 

 both solid and liquid, is usually deposited in the lot or on the fields 

 where needed. Of course when the doors are closed, preventing free 

 exit of the hogs, this sanitary advantage is absent; likewise in very 

 cold weather the hogs often manure in the house. Feeding and watering 

 is usually done outside, this also tending to keep the swine healthier 

 because of the drier, cleaner, more sanitary floor and bedding. 



(f) Dust is not so liable to be a menace where dirt floors are de- 

 pended upon; mere moving solves the difficulty. 



(g) Quarantine of acquired animals may be efficiently enforced. The 

 small movable house with dirt floor is a convenient and effectual deten- 

 tion hospital. 



4. Construction is simplified: Some features which save time and 

 energy are: (a) pig saving fenders are' not necessary on the sides of the 

 "A" shaped type because of slanting roof; (b) permanent foundations 

 are dispensed with; (c) the building can be constructed under cover, 

 thus avoiding the cold weather of winter and hot sun of summer; 

 (d) the location need not be determined definitely because of the movable 

 feature; (e) prospective planning as to methods and details of con- 

 struction is reduced. Building of the small, individual houses may be 

 done quickly by anyone having a working knowledge of carpentry. Many 

 Iowa boys have successfully built the individual hog house. 



5. More practical and economical for beginners and Oivners of small 

 herds: Requires but a small initial outlay because of low first cost. 

 The prospective swineman is thus enabled to gradually add to his housing 

 facilities as his herd increases. 



6. Adaptability to the renter: Being a movab'.e, economical unit, 

 the man who rents can better afford this type than the larger one, 

 should the landlord not care to furnish hog houses. The knock-down 

 style makes it easy to transport in compact form. 



7. Artificial heat in feic pens easily supplied: In ordinary weather 

 the animals furnish sufficient warmth; however, when extreme cold pre- 

 vails provisions for heating is in order. The common barn lantern 

 usually provides sufficient warmth, but sometimes the small kerosene 

 heating stove may be advantageously pressed into service.
