Dietary 25(OH)D3 supplementation to gestating and lactating sows and their progeny affects growth performance, carcass characteristics, blood profiles and myogenic regulatory factor-related gene expression in wean-finish pigs
Objective: This experiment investigated the effects of supplementing vitamin D3-fortified sow and progeny diets with 25(OH)D3 on growth performance, carcass characteristics, immunity, and pork meat quality.Methods: The present study involved the assessment of supplementing the diet of sows and their...

Summary: | Objective: This experiment investigated the effects of supplementing vitamin D3-fortified sow and progeny diets with 25(OH)D3 on growth performance, carcass characteristics, immunity, and pork meat quality.Methods: The present study involved the assessment of supplementing the diet of sows and their progeny with or without 25 (OH)D3 in a 2×2 factorial arrangement on the performance and production characteristics of wean-finish pigs. Forty-eight multiparous sows were assigned to a basal diet containing 2000 IU/kg vitamin D3 and supplemented without (CON) or with (TRT) 50 μg/kg 25 (OH)D3. At weaning, a total of 80 pigs each from CON and TRT sows were allocated to weaning and growing-finishing basal diets fortified with 2,500 and 1,750 IU/kg vitamin D3 respectively and supplemented without or with 50 μg/kg 25(OH)D3.Results: Sows fed 25(OH)D3-supplemented diets improved pre-weaning growth rate of nursing piglets. A significant sow and pig weaning diet effect was observed for growth rate and feed efficiency (p |
