Four experiments were conducted to investigate the effect of fat-soluble vitamin administration to sows or newborn pigs on plasma vitamin status. In Exp. 1 and 2, a total of 24 and 43 newborn pigs were allotted to control and vitamin treatments (vitamin $D_3$ with variable addition of vitamins A and E) orally or by i.m. injection. In Exp. 3, pigs from Exp. 2 were allotted to 2 treatments (${\alpha}$vitamins $D_3$ and E in drinking water) for 14 d postweaning. In Exp. 4, twenty-four gestating sows were used for 2 treatments (${\pm}injection$ of a vitamin $D_3$/A/E product 2 wk prepartum). In Exp. 1 and 2, when vitamin $D_3$ was administrated orally or by i.m. injection on d 1 of age, pigs had increased plasma 25-hydroxycholecalciferol (25-OH $D_3$) concentration 10 d after administration compared with control pigs (p<0.05). The injectable administration with vitamin $D_3$ and E was able to achieve higher plasma 25-OH $D_3$ (p<0.05) and ${\alpha}$-tocopherol (p<0.05) concentrations than oral administration. At weaning, the pigs in the injection group had higher plasma 25-OH $D_3$ concentration than those in the other groups in both studies (p<0.05). In Exp. 3, water supplementation of vitamin $D_3$ and E postweaning increased plasma 25-OH $D_3$ and ${\alpha}$-tocopherol concentrations at d 14 postweaning (p<0.01). In Exp. 4, when sows were injected with the vitamin $D_3$ product prepartum, serum 25-OH $D_3$ concentrations of sows at farrowing (p<0.01), and in their progeny at birth (p<0.01) and weaning (p<0.05) were increased. These results demonstrated that fat-soluble vitamin administration to newborn pigs increased plasma 25-OH $D_3$ concentration regardless of administration routes and ${\alpha}$-tocopherol concentration by the injectable route, and that water supplementation of vitamin $D_3$ and E to nursery pigs increased plasma 25-OH $D_3$ and ${\alpha}$-tocopherol concentrations. Additionally, injecting sows with vitamin $D_3$ prepartum increased 25-OH $D_3$ in sows and their offspring. If continued research demonstrates that the serum levels of 25-OH $D_3$ are critical in weanling pigs, a variety of means to increase those levels are available to swine producers.

Objective: Two experiments were conducted to evaluate vitamin D3 administration to nursery pigs by injection or in drinking water on serum 25-hydroxycholecalciferol (25-OHD3) concentrations. Methods: At weaning, 51 pigs (27 and 24 pigs in experiments 1 and 2, respectively) were allotted to vitamin D3 treatments. Treatments in experiment 1 were: i) control (CON), no vitamin administration beyond that in the diet, ii) intramuscular (IM) injection of 40,000 IU of vitamin D3 at weaning, and iii) water administration, 5,493 IU of vitamin D3/L drinking water for 14 d postweaning. Treatments in experiment 2 were: i) control (CON), no vitamin administration, and ii) water administration, 92 IU of d-α-tocopherol and 5,493 IU of vitamin D3/L drinking water for 28 d postweaning. The lightest 2 pigs within each pen were IM injected with an additional 1,000 IU of d-α-tocopherol, 100,000 IU of retinyl palmitate, and 100,000 IU of vitamin D3. Results: In both experiments, serum 25-OHD3 was changed after vitamin D3 administration (p<0.05). In experiment 1, injection and water groups had greater values than CON group through d 35 and 21 post-administration, respectively (p<0.05). In experiment 2, serum values peaked at d 3 post-administration in the injection groups regardless of water treatments (p<0.05) whereas CON and water-only groups had peaks at d 14 and 28 post-administration, respectively (p<0.05). Even though the injection groups had greater serum 25-OHD3 concentrations than the non-injection groups through d 7 post-administration regardless of water treatments (p<0.05), the water-only group had greater values than the injection-only group from d 21 post-administration onward (p<0.05). Conclusion: Serum 25-OHD3 concentrations in pigs increased either by vitamin D3 injection or drinking water administration. Although a single vitamin D3 injection enhanced serum 25-OHD3 concentrations greater than water administration in the initial period post-administration, a continuous supply of vitamin D3 via drinking water could maintain higher serum values than the single injection.
