Synergistic Effects of 25-Hydroxyvitamin D₃, Phytase, and Probiotics on Growth, Calcium and Phosphorus Metabolism, and Bone Development in Weaned Piglets Fed Low Ca-P Diets.

ABSTRACT: Seventy 28-day-old weaned barrow piglets (Duroc × Landrace × Large White; 7.2 ± 0.20 kg) were used to determine the effects of 25-hydroxyvitamin D₃ (25-OH-VD₃) combined with phytase and probiotics on calcium and phosphorus metabolism and bone development. Five dietary groups were tested: basal diet + 50 µg/kg 25-OH-VD₃ (CON); basal diet with 17% reduced calcium and phosphorus + 50 µg/kg 25-OH-VD₃ (LCP); LCP + 50 mg/kg phytase (LH); LCP + 10 mg/kg probiotics (LC); LCP + 50 mg/kg phytase + 10 mg/kg probiotics (LHC). The experiment lasted for 31 days, including 3 days adaptation period. Apparent phosphorus digestibility was higher in the LH and LHC groups than in the CON group (p < 0.05).
