Dietary 25-hydroxycholecalciferol modulates gut microbiota and improves the growth, meat quality, and antioxidant status of growing-finishing pigs.

ABSTRACT:

Introduction

25-Hydroxycholecalciferol (25OHD₃) is the active metabolite of regular vitamin D₃ in vivo, which has a stronger biological activity and is more easily absorbed by the intestine than regular vitamin D₃. Our study aimed to detect the potential influences of 25OHD₃ on pork quality, antioxidant status, and intestinal microbiota of growing-finishing pigs receiving low-phosphorus (P) diet.

Methods and results

Forty pigs [initial body weight (BW): 49.42 ± 4.01 kg] were allocated into two groups including low-P diet (CON group) and low-P diet supplemented with 50 μg/kg 25OHD₃ (25OHD₃ group). The whole experiment lasted for 88 days, including phase 1 (day 1-28), phase 2 (day 29-60), and phase 3 (day
