Highlights
There has been renewed interest in keeping pigs outdoors due to public interest in animal welfare and more natural production systems (Edwards et al, 1996)
There is no common knowledge if weaned pig response in the same way as older ones, and what is a subsequent effect of feeding to weaned piglets a diet rich in fibre on the growth of their gastrointestinal tract after return to commercial feeding
Supplementation of the diet B with grass meal resulted in increase of crude fibre content, acid-detergent fibre (ADF) and neutral-detergent fibre (NDF) fraction causing a deterioration of nutritional value, especially metabolizable energy and protein/lysine content (Table 2)
Summary
There has been renewed interest in keeping pigs outdoors due to public interest in animal welfare and more natural production systems (Edwards et al, 1996) In such maintenance condition roughage feeds are widely used. There is no common knowledge if weaned pig response in the same way as older ones, and what is a subsequent effect of feeding to weaned piglets a diet rich in fibre on the growth of their gastrointestinal tract after return to commercial feeding. Such knowledge would be useful in out-door/organic rearing system. It could be used to work out the strategy of nutrition of pigs kept in such condition
