摘要：
To determine the value of providing insulated farrowing huts, data were analysed from two newly established outdoor units, each having contemporary farrowings in huts of similar 'half-round' design (Figure 1) with (I) and without (U) insulation. On unit A, 284 litters were recorded over a 22 month period, with a mean total litter size of 10.9 (sem 0.14). On unit B, 338 litters were recorded over a 17 month period, with a mean total litter size of 11.6 (sem 0.12).
