Abstract / Zusammenfassung

In swine nutrition, dietary fibres are commonly categorized depending on their chemical characteristics. As it is known from other species, physical characteristics regarding the structure and particle size of roughage also have a major impact on digestive physiology. However, this was only sparsely studied in pigs. It was the aim of the study to compare the impact of fibre particle size and chemical characteristics on faecal pH, nitrogen, and short chain fatty acid (SCFA) concentrations in adult sows. The upper 20 cm of hemp plants (seeds, flowers, stems and leaves; Finola) were harvested and subjected to hot-air-drying. Sixteen pluriparous, non-gestating German Landrace sows were kept in outdoor cages and fed a standard diet for gestating sows. In a cross-over design, dried hemp was added to the morning ration, either intact or ground, at an inclusion level of 200 g/d, for two weeks each. Afterwards, apple pomace was added either intact or ground (200 g/d) for two weeks each. Faecal samples were collected at the end of each 2-week feeding period and dry matter (DM) content, pH, nitrogen, SCFA, and lactate concentrations were obtained. One-way ANOVA with Tukey post-hoc test was performed to determine differences and form subgroups. Differences were considered statistically significant at P < 0.05. Faecal DM was significantly higher in sows fed apple pomace, especially when intact, compared to sows fed hemp (P > 0.001). Feeding hemp instead of apple pomace led to a higher nitrogen excretion, with the highest values when not ground (P = 0.008). Acetate, i-butyrate, lactate, and total SCFA concentrations were lower when sows received apple pomace (P = 0.007; P = 0.049, P < 0.001; P = 0.072). Faecal pH was not affected by dietary treatment (P = 0.488). Fibre rich feedstuff may influence faecal parameters differently depending on their chemical and physical characteristics.
