Dietary fibre supplemented pre-mating diets do not improve follicle development and litter characteristics in primiparous sows

Piglet birth weight is an important factor for their survival and growth. As the pre-mating diet influences sow's metabolic state, this may have impact on follicle development after weaning subsequent piglet weight. We investigated effect of dietary fibre (DF; sugar beet pulp (SBP) microfibrillated cellulose (MFC)) hormones metabolites (IGF-1, non-esterified fatty acids (NEFA), creatinine, urea leptin), development, litter characteristics at farrowing in 58 hyper-prolific primiparous sows 16.5 ± 0.4 piglets used three consecutive batches. supplemented commercial diets (CON) with SBP MFC during last week lactation weaning-to-oestrus interval (WEI). measured diameters ultrasound collected preprandial blood samples weaning, 3 days oestrus. A tendency higher average daily feed intake (ADFI; 5.69 v. 6.61 kg/day, P < 0.07) significant lower backfat (BF; 1.1 0.2 mm, 0.05) loss were observed than one before weaning. Total (TDF) was CON sows, whereas TDF similar to (775.0 vs. 900.6 840.9 g/day, respectively, CON, MFC, 0.05). Creatinine concentration (162.9 136.6 mmol/L, 0.001). Other reproductive parameters not affected by diets. At farrowing, there no difference (P > In our study, different types DF fed body protein mobilization lactation. However, supplementation mating did neither improve nor sows.
