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 …

Kansas Agricultural Experiment Station Research Reports
A total of 350 nursery pigs (PIC 1050 barrows, initially 33.2 lb and 49 d of age) were used in a 21-d study to determine the aP release curve for a novel phytase product (Microtech 5,000, VTR Bio-tech Co., Guangdong, China). Pigs were randomly allotted to pens at arrival to the facility, and on d 0 of the trial pens were allotted to 1 of 7 treatments in a randomized complete block design. There were 5 pigs per pen and 10 pens per treatment. Pigs were fed corn-soybean meal-based diets formulated to 1.25% SID lysine. A single batch of the …
