Serum Ca and P concentrations (mg/dL) at d 0 and 100 of gestation, farrowing, and weaning (d 21 of lactation) in sows fed diets formulated to supply 1,500, 3,000, or 6,000 IU vitamin D3/kg of the complete diet. Superscripts denote tendencies (0.05 < P ≤ 0.10): xlinear dietary effects and yquadratic dietary effects. Physiological range based on Friendship et al. (1984).

Serum Ca and P concentrations (mg/dL) at birth, and weaning (d 21) in pigs from sows fed diets formulated to supply 1,500, 3,000, or 6,000 IU vitamin D3/kg of the complete diet. Superscripts denote tendencies (0.05 < P ≤ 0.10): yquadratic maternal diet effect. Physiological range based on Friendship et al. (1984).

Serum Ca and P concentrations (mg/dL) at weaning, d 10, 21, and 35 in nursery pigs from sows fed diets formulated to supply either 1,500, 3,000, or 6,000 IU vitamin D3/kg of the complete diet, and fed diets formulated to either 1,800 or 18,000 IU vitamin D3/kg from weaning until d 10. Superscripts denote tendencies (0.05 < P ≤ 0.10): yquadratic maternal diet effect. Physiological range based on Friendship et al. (1984).
