Extract
With a growing interest in less-intensive housing systems, pig breeding companies have developed genotypes which are supposedly better suited to these conditions. The aim of this experiment was to compare the performance of progeny from sows of 2 types:
a) ‘indoor’ - Large White x Landrace
b) ‘outdoor’ - 25% Meishan or 25% Duroc with 50%Large White and 25% Landrace
All sows were mated to a Large White boar and the progeny housed in one of three finishing systems - outdoor paddocks, straw yards or fully slatted pens. The systems were typical of commercial practice, with an automatically controlled natural ventilation system and 0.6 m2 of floor space per pig in fully-slatted pens. Outdoor paddocks and straw yards had minimal environmental control and space allowances of 20.0 m2 and 1.6 m2 per pig respectively. Pigs in outdoor paddocks were retained on cereal stubble with electric fencing and had free access to a bedded shelter hut.
