Increasing the level of hemicelluloses in the lactation diet affects the faecal microbiota of sows and their piglets without affecting their performances

Table 7 Growth performance and occurrence of diarrhoea in piglets characterised by slow and fast growth and born from sows fed with increasing levels of hemicelluloses during the lactation period

^†Dietary Treatment: HC13 = Sow’s lactation diet containing 13% hemicelluloses; HC11 = Sow’s lactation diet containing 11% hemicelluloses; HC9 = Sow’s lactation diet containing 9% hemicelluloses; HC8 = Sow’s lactation diet containing 8% hemicelluloses
^‡Growth categories: SG = piglets displaying slow growth (average daily gain: 167 ± 10.1 g/d) from 0 to 16 days of age; FG = piglets displaying fast growth (average daily gain: 280 ± 10.1 g/d) from 0 to 16 days of age
^§P-values: The presented P-values depict the overall sow dietary treatment (T), growth category (G), the interaction between sow dietary treatment and growth category (T x G), linear (L) and quadratic (Q) effects
