“…The average days to first ovulation postpartum of cows fed NDCA (16.3 ± 0.4 d) and cows fed ND (17.93 ± 0.6 d) was lower than cows fed CON 18.93 ± 0.9 d; Ryan et al, 2020). Development of the DF of the first follicular wave postpartum is highly correlated with conception rates (Butler, 2003).…”

“…Others have established that feeding acidogenic salts or products to prepartum negative DCAD diets improved concentrations of Ca in blood at calving, reduced the risk of HC and uterine diseases, and improved lactation performance (Oetzel et al, 1991;Santos et al, 2019;Ryan et al, 2020). Goff and Koszewski (2018) reported that 0.46% Ca diets prepartum were not low enough in Ca to stimulate parathyroid hormone secretion and place the cow in negative Ca balance before calving.…”

“…In a recent study performed at the University of Illinois, multiparous Holstein cows were enrolled to evaluate the effects of feeding a negative DCAD, fully acidified diet prepartum at 2 different concentrations of dietary Ca on their subsequent reproductive performance. Treatments began at 28 d before expected calving and were a positive DCAD diet (CON; +6 mEq/100 g of DM) with low dietary Ca (0.4% DM; urine pH = 8.12); a fully acidified, negative DCAD diet (ND; −24 mEq/100 g of DM; urine pH = 5.76) with low dietary Ca (0.4% DM); and a fully acidified, negative DCAD diet (NDCA; −24 mEq/100 g of DM; urine pH = 5.67) with high dietary Ca (2.0% DM; Glosson, 2018;Ryan et al, 2020).…”

“…The Ca balance seems to be associated with reproductive success in dairy cows. Ryan et al (2020) reported that cows fed CON [4/19 pregnancy per artificial insemination (P/AI)] tended to have lower P/AI than cows fed NDCA (11/21 P/AI) but not ND (8/20 P/AI). Additionally, cows fed NDCA tended to have greater intensity of the uterine protein occludin (e.g., Ca dependent tight-junction protein) expression than cows fed ND along with cows fed ND having higher plasma haptoglobin concentrations than cows fed NDCA in the prepartum and postpartum periods (Ryan et al, 2020).…”

“…The mechanisms of action include maintaining parathyroid hormone sensitivity to Ca homeostasis and increasing calciotropic receptor numbers (DeGaris and Lean, 2008). Feeding a negative DCAD diet prepartum (fully or partially acidified) increased the subsequent reproductive performance as well as improving the Ca status of the cow (Chapinal et al, 2012;Martinez et al, 2018;Ryan et al, 2020).…”

Multiparous, lactating Holstein cows (n = 32) were randomly assigned to 1 of 2 dietary treatments [TMR with rumen-protected Met (RPM) or TMR without RPM (CON)], and within each dietary treatment group cows were randomly assigned to 1 of 2 environmental treatment groups in a split-plot crossover design. In phase 1 (9 d) all cows were fed ad libitum and in thermoneutral conditions (TN). In phase 2 (9 d), group 1 (n = 16) was exposed to a heat stress (HS) challenge (HSC). Group 2 cows (n = 16) were pair-fed (PFTN) to HSC counterparts and remained in TN. After a 21-d washout period, the study was repeated (period 2) and the environmental treatments were inverted relative to treatments from phase 2 of period 1, while dietary treatments remained the same for each cow. During phase 1, cows in RPM had greater plasma Met concentration compared to cows in CON (59 µM and 30 µM, respectively; P < 0.001). Cows in PFTN had a greater decrease (P < 0.05) in plasma insulin than cows in HSC at 4 h (-2.7 µIU/mL vs. -0.7 µIU/mL) and 8 h (-7.7 µIU/mL vs. -0.4 µIU/mL) during phase 2. Compared to cows in PFTN, cows in HSC had an increase (P < 0.05) in plasma serum amyloid A (-59 µg/mL vs. +58 µg/mL), serum haptoglobin (-3 µg/mL vs. +33 µg/mL), plasma lipopolysaccharide binding protein (-0.27 µg/mL and +0.11 µg/mL), and plasma interleukin-1β (-1.9 pg/mL and +3.9 pg/mL) during phase 2. In conclusion, HSC elicited immunometabolic alterations; however, there were limited effects of RPM on cows in HSC.

The objective of this experiment was to determine the effects of dietary vitamin D source on serum calcium (Ca), urinary Ca excretion and milk production when fed in combination with a prepartum acidogenic negative DCAD diet. Non-lactating, pregnant multiparous cows (n=15), balanced for breed (Holstein n = 9 and Jersey n = 6) and previous mature equivalent milk production, were assigned to 1 of 3 treatments (5 cows/treatment), consisting of a control (PCH; positive DCAD, 8.9 mEq/100g DM) and two negative DCAD diets (-15.4 mEq/100g DM), one with vitamin D3 (Cholecalciferol; NCH), and one with 25-hydroxyvitamin D3 (calcidiol; NCA; DSM Nutritional Products). The treatments were formulated to provide 1.95 mg/d of vitamin D and were fed 28 d prior to expected calving date. Delivery of vitamin D sources was accomplished by manufacture of a pellet and 2 kg of these pellets were individually fed simultaneously each day along with 2 kg of ground corn daily at 0800. Negative DCAD treatments were formulated to provide 0.46 kg/d of Animate (Phibro Animal Health) and, if needed, additional Animate was top-dressed at each feeding to achieve a urine pH between 5.5 – 6.0 based on the previous day’s urine pH. Close-up cows had ad libitum access to chopped bermudagrass (Cynodon dactylon L.) hay and hay intake was measured using SmartFeed Pro systems (C-Lock Inc.; Rapid City, SD). Prepartum urine and serum samples were collected weekly and serum was collected 36, 48, and 72 h post-calving. Prepartum DMI as a percent of body weight was not (P = 0.66) affected by treatments. Cows fed NCH and NCA had greater (P = 0.02) prepartum serum Ca than PCH and tended to have greater urinary Ca excretions (P = 0.10). Average postpartum serum Ca (mg/dL) was greater (P = 0.05) for cows fed NCH (8.8) compared with PCH (7.8), whereas NCA (8.4) was numerically intermediate and not (P > 0.05) different from either of the other treatments. Postpartum DMI was not affected by treatment (P = 0.39). Daily MY (kg/d) was greatest (P < 0.01) for NCA (37.5) compared with the other treatments and NCH (34.1) was intermediate and greater than PCH (29.9). These results suggest that an acidogenic prepartum diet in combination with vitamin D was effective in maintaining peripartum serum Ca and the 25-hydroxy form of vitamin D improved MY compared with NCH in early lactation.
