Jørgensen, Henry; Lærke, H.N. and Carlson, D. (2012) Influence on the ileal and fecal digestibility of forages inclusion in the diet. In: Book of Abstracts.
The present investigation aimed to study the ileal and fecal digestibility of three forages (Clover grass, Clover grass silage and Pea-Barley silage) supplemented to a basal diet. A total of 24 pigs, adapted to eating forages by supplementing a basal feed with clover grass silage from weaning, were fitted with a T-cannula at the terminal ileum at approximate 30 kg LW. For each of the three types of forage, two balance trials with 4 weeks interval were carried out. Two pigs in each test were fed the basal diet while 6 others were fed the basal diet plus forage throughout the whole experiment. The intake of forages was relative low and quite variable and accounted on average for only 10-12 % of the daily dry matter intake. Ileal digestibility estimated by collection from the T-cannula was higher than the digestibility estimated by the slaughter technique indicating some separation of the digesta collected from the T-cannula. The forages had, as expected, a lower fecal DM and energy digestibility than the basal diet (P<0.05). The fresh clover grass had a higher energy digestibility than the two silages (60 vs 48 %, P<0.05). Inclusion of 10 % of gross energy in the diet from clover grass reduced the rations energy digestibility relatively by 2.2 %, while clover grass silage and the pea-barley silage to reductions of 3.4 and 5.0 % (P<0.05), respectively.
