The Effects Of Maternal Dietary Supplementation Of Cholecalciferol (Vitamin D3) And 25(Oh)D3 On Sow And Progeny Performance, M. T. Thayer, J. L. Nelssen, A. J. Langemeier, J. Morton, J. M. Gonzales, S. R. Kruger, Z. Ou, A. J. Makowski, J. R. Bergstrom

Kansas Agricultural Experiment Station Research Reports

A total of 69 sows (DNA Line 200 × 400) and their progeny were used to determine if feeding a combination of vitamin D₃(Rovimix D₃, 500,000 IU/g; DSM Nutritional Products, Parsippany, NJ) and 25(OH)D₃(Hy-D, DSM Nutritional Products, Parsippany, NJ) influences neonatal and sow vitamin D3 status, muscle fiber morphometrics and development of the piglets, and subsequent growth performance to market. Within 3 days of breeding, sows were allotted to 1 of 3 dietary treatments fortified with 680 IU/lb vitamin D₃(CON), 227 IU/lb vitamin D₃+ 11.3 μg/lb 25(OH)D₃(DL), or …

Evaluating The Impact Of Maternal Vitamin D Supplementation On Sow Performance, Serum Vitamin Metabolites, Neonatal Muscle And Bone Characteristics, And Subsequent Pre-Weaning Pig Performance, J. R. Flohr, J. C. Woodworth, M. D. Tokach, S. S. Dritz, R. D. Goodband, J. M. Derouchey, J. R. Bergstrom

Kansas Agricultural Experiment Station Research Reports

A total of 56 gestating sows (PIC 1050; 35-d post-insemination) were used in a 30-d trial to determine the serum 25(OH)D₃response to increasing concentrations of vitamins D3. At initiation, sows were randomly allotted to 1 of 7 dietary vitamin D₃treatments (91, 363, 726, 1,451, 2,903, 5,806, or 11,612 IU of vitamin D₃/lb of complete diet) with 8 sows per treatment. All sows were fed 5.5 lb daily at 0800. Increasing vitamin D3 increased (quadratic; P<0.001) serum 25(OH)D₃with the response depicted by the following prediction equation:

Serum 25(OH)D3_,ng/mL = 35.1746 + (0.002353 × …

Evaluating The Effects Of Maternal Vitamin D Supplementation On The Subsequent Growth Performance And Carcass Characteristics Of A Subsample Population Of Growing Pigs, J. R. Flohr, J. C. Woodworth, M. D. Tokach, S. S. Dritz, R. D. Goodband, J. M. Derouchey, J. R. Bergstrom

Kansas Agricultural Experiment Station Research Reports

A subsample of 448 growing pigs (PIC 327 × 1050), or approximately 50% of pigs weaned from sows fed varying dietary vitamin D regimens, were used in a split-plot design to determine the influence of maternal and nursery vitamin D regimens on growth performance. Sows were previously administered diets containing vitamin D as either: 1) low vitamin D₃(363 IU/lb); 2) medium vitamin D₃(907 IU/lb); 3) high vitamin D₃(4,354 IU/lb); or 4) 23μg 25(OH)D₃/lb (Hy-D, DSM Nutritional Products Inc, Parsippany, NJ) as described by Flohr et al. (20153) throughout gestation and …
