The content of short chain fatty acids in the jejunal digesta, caecal digesta and faeces of growing pigs

Short chain fatty acids (SCFAs) are intermediates from microbial fermentation of proteins or saccharides. Little is known about their production in different parts of intestine and therefore the aim of the present study was to examine, using 7 double-cannulated gilts (initial BW: 25 ± 0.5 kg), the production of the SCFAs in a jejunal digesta, caecal digesta and faeces. After a 25-d recovery period, a 70-d experimental period followed. On days 28; 42; 56 and 70, samples of jejunal, caecal digesta and faeces were collected. In the samples of jejunal and caecal digesta and in faeces, the content of dry matter (DM), crude protein (CP) and SCFAs was determined. The highest content of DM ( P P P P P P P P P P P
