Corrigendum to “Effect of feeding 25-hydroxyvitamin D3 with a negative cation-anion difference diet on calcium and vitamin D status of periparturient cows and their calves” (J. Dairy Sci. 98:5588–5600)

Abstract

Table 7 on page 5597 contained some incorrect data for serum 25-(OH)D3 concentrations due to an error in unit conversion. The table is shown below, with corrected values in bold. The error does not affect the statistical analysis (the P-values for these data were correct as reported) or Figure 4.Table 7Effect of prefresh diet of dam on vitamin D metabolites in their milk and in serum from their calves1Birth samples were taken before consuming colostrum and sixth milking sample was taken within 2h after calves consumed their sixth feeding of milk. Calves were only fed colostrum or milk from their dams. For milk measures and serum 25-(OH)D3, time and time × treatment were significant (P<0.01), but only time was significant for 1,25-(OH)2-D3 (P<0.01). Milk from cows fed DCAD + 25 D did not have measurable concentrations of vitamin D3 and that treatment was excluded from the statistical analysis.ItemTreatment2Control diet contained vitamin D3 and no supplemental anions; DCAD + D diet contained vitamin D3 and supplemental anions; DCAD + 25D diet contained 25-(OH)D3 and supplemental anions.SEMP-value3DCAD=effect of feeding supplemental anions (control vs. DCAD + D); VD=effect of type of supplemental vitamin D (DCAD + D vs. DCAD + 25D).ControlDCAD + DDCAD + 25DDCADVDMilk Vitamin D3, pg/mL First milking colostrum471340ND55.10.09— Sixth milking324295ND75.40.77— 25-(OH)D3, pg/mL First milking colostrum1,0218913,690163.20.720.001 Sixth milking4583401,088167.70.640.001 Milk, 28 DIM358473607168.70.370.20Serum of calves 25-(OH)D3, ng/mL Birth25.921.160.85.100.510.001 Sixth feeding17.315.737.82.860.680.001 1,25-(OH)2D, pg/mL Birth149.0136.8160.130.50.770.59 Sixth feeding192.3212.1257.233.60.350.68 Calcium, mg/dL Birth11.711.511.30.180.490.26 Sixth feeding12.011.611.40.190.160.531 Birth samples were taken before consuming colostrum and sixth milking sample was taken within 2 h after calves consumed their sixth feeding of milk.

Effect of feeding 25-hydroxyvitamin D3 with a negative cation-anion difference diet on calcium and vitamin D status of periparturient cows and their calvesJournal of Dairy ScienceVol. 98Issue 8PreviewHolstein cows (>1 gestation) were fed 1 of 3 diets during the last 13 d of gestation (ranged from 22 to 7 d). The control diet (16 cows) was formulated to provide 18,000 IU/d of vitamin D3 and had a dietary cation-anion difference (DCAD) of 165 mEq/kg (DCAD = Na + K – Cl – S). The second diet (DCAD + D) provided the same amount of vitamin D3 but had a DCAD of −139 mEq/kg (17 cows). The third diet (DCAD + 25D) had no supplemental vitamin D3 but provided 6 mg/d of 25-(OH) vitamin D3 [25-(OH)D3] with a DCAD of −138 mEq/kg (20 cows). Full-Text PDF Open Archive
