The boar’s pen should have a covered area of 6.25 - 7.5 m and open area of 8.8
2
- 12 m for exercise. The walls should have a minimum height of 1.5 m. Females
2
can be housed in an open yard type with partial roofing as in the case of boars. An
area of 2 m per animal may be provided where a total of 10 - 15 females can be
2
grouped in a pen. Farrowing sows may be housed individually in a farrowing pen

of 10 m with dimensions of 2.5 m x 4.0 m. The farrowing pen should be equipped
2
with guard rails, creep area as well as feed and water troughs. A covered concrete
yard for feeding and resting (having feed and water trough) should be arranged in
the front side and an open yard in the rear is considered sufficient for housing the
growing and finishing pigs or fatteners. The total space requirement may be 2 m per
2
grower/fattener pig. The summary of space requirement in pig housing is presented
in Table 4.2 while pig housing structures including pig house plan for commercial
farm, traditional pig house, modern pig house and modern farrowing pen equipped
with farrowing crate are presented in Figures 4.13, 4.14 and 4.15, respectively.
