^∗ p < 0.05; ^†extensive system = animals of relatively small number are permanently penned and feed on agriculture by-products and kitchen wastes; semi-intensive system = cross-bred animals are permanently penned in piggeries with a roughcast floor and feed on kitchen waste, agricultural by-products and often industrial feed; intensive system = animals are improved breeds, indoors, in high number; the piggery is a modern building; feedstuff is exclusively industrial; management system is modern.
