Influence Of Herbal Active D On Nursery Pig Growth Performance, Larissa L. Becker, Mike D. Tokach, Jason C. Woodworth, Robert D. Goodband, Joel M. Derouchey, Jordan T. Gebhardt

Kansas Agricultural Experiment Station Research Reports

A total of 2,268 pigs (L337 × 1050 PIC; initially 12.1 ± 0.39 lb) were used in a 42-d growth study to evaluate the effects of herbal active D on growth performance, bone characteristics, and serum parameters of nursery pigs. Pigs were weaned at approximately 21 d of age and randomly allotted to 1 of 3 dietary treatments in a randomized complete block design. A total of 84 pens were used with 27 pigs per pen and 28 replications per treatment across 2 rooms. Pens were blocked by BW and weaning date. Dietary treatments were corn-soybean meal-based and fed in …

Diagnostic Survey Of Biological Measurements Used To Determine Bone Mineralization In Pigs Across The Us Swine Industry, Hadley R. Williams, Mike D. Tokach, Jason C. Woodworth, Joel M.

Kansas Agricultural Experiment Station Research Reports

Pigs from 64 commercial sites across 14 production systems in the Midwest US were used to evaluate the baseline biological measurements used to determine bone mineralization. Three pigs were selected from each commercial site representing: 1) a clinically normal pig (healthy); 2) a pig with evidence of clinical lameness (lame); and 3) a pig from a hospital pen that is assumed to have recent low feed intake (unhealthy). Pigs ranged in age from nursery to market weight, with the three pigs sampled from each site representing the same age or phase of production. Blood, urine, metacarpal, fibula, 2nd rib, and …

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 …
