FARMER'S CYCLOPEDIA OF LIVE STOCK 



control of the grower over disease, as 

 any outbreak which may occur may be 

 promptly isolated, and a few pigs to- 

 gether do better than when in large 

 herds. 



Figure 338 shows the one form of these 

 cots which is especially satisfactory in 

 winter, but objectionable in summer, 

 as it does not afford sufficient protection 

 against heat. It is considered an espe- 

 cially good form of cot for breeding sows 

 as at farrowing time the sow cannot lie 

 down so close to the sloping roof but 

 that the pigs can get behind her and 

 thus prevent themselves from being 

 crushed. 



The house is arranged on skids so that 

 it may be easily moved by hitching a 



Shaw at the Michigan station. It i9 

 6x8 feet at the foundation, with the 

 sides raised perpendicularly 3 feet be- 

 fore receiving the half pitch roof board. 

 The center boards on the sides are hinged 

 so that they can be swung open in hot 

 weather; the opening thus made is cov- 

 ered with strong woven wire clamped 

 above and below with inch boards; the 

 inner clamp boards project an inch 

 above the outer boards, thus breaking 

 joints and preventing any draft when 

 the openings are closed. The roof boards 

 are also hinged so that they can be opened 

 during hot weather. These openings 

 permit a free circulation of air which 

 lowers the temperature and contributes 

 to the comfort of the pigs. These open-

team to it. These skids should not be 

 attached to the house as they soon rot 

 out. Another form of these pens is 

 shown in Fig. 342. This house is built 

 6x8 and is formed of five separate pieces 

 so constructed that they can be bolted 

 together, and taken down and removed 

 when desired. This form is especially 

 warm in summer unless raised up slightly 

 from the ground. The sections are also 

 difficult for one man to handle and 

 on this account it is not moved as fre- 

 quently as it should be. On this account 

 also it is desirable that all portable 

 hog houses be built on skids so that they 

 can be removed by one man and a team. 

 Fig. 341 shows an improved form of 

 these portable hog houses, designed by 



ings close down tightly, leaving warm 

 quarters during the coldest weather. 

 "This form of house is rather expensive 

 as it contains 160 feet stock lumber, 

 60 feet matched, 20 feet 4x6-inch, 12 feet 

 4x4-inch and 44 feet 2x4-inch." 



FENCES FOR YARDS AND PAS- 

 TURES 



Good fences are absolutely necessary 

 to peace of mind in growing hogs. For 

 the small runs adjacent to the pens, 

 tight board fences are perhaps the most 

 satisfactory of anything, but lumber 

 is becoming so expensive that this kind 

 of a fence is more costly than a wire 

 fence. A woven wire fence 3 feet high 

 will be sufficient to retain the hogs at
