“…Gunal et al (2021) established that one of the functions of carotenoids, in particular lutein and zeaxanthin, is to improve mitochondrial function by reducing inflammation and activating the erythroid link of haemopoiesis. Kadek et al (2021) theorised that vitamin A, E and β-carotene deficiency adversely affects calf health and increases mortality due to low levels of α-tocopherol and β-carotene. The authors proved that the paranteral administration of vitamins A and E and β-carotene to pregnant cows increased the haemoglobin content, haematocrit and red blood cell count in calves.…”

To examine the effects of feeding a vitamin and mineral supplement to beef heifers throughout gestation on mineral status and hormone/endocrine profiles in the dam and calf, and morphometric characteristics and organ mass of the calf at 30 h after birth, Angus-based heifers (n = 72, 14 to 15 months of age, initial body weight [BW] = 380.4 ± 50.56 kg) were estrus synchronized and artificially inseminated (AI) with female-sexed semen. Heifers were blocked by BW and randomly assigned to receive either a basal diet (CON; n = 36) or a basal diet plus a vitamin and mineral supplement (VTM; n = 36) via an individual feeding system beginning at breeding, with both diets targeting BW gains of 0.45 kg heifer-1•d-1. Heifers not pregnant after first AI (CON, n = 19; VTM, n = 18) were re-bred via AI 60 d after treatment initiation, and heifers gestating female fetuses (CON, n = 7; VTM, n = 7) received treatments throughout gestation and were experimental units for this study. Calves were separated from their dams and fed colostrum replacer within 2 h of birth and euthanized 30 h after the first feeding. Calf morphometrics were recorded, and tissues were weighed and sampled. Serum from the dam at calving and serum, liver, and muscle from the calf at 30 h were analyzed for concentrations of minerals. Serum from the dam and calf were analyzed for concentrations of leptin, vitamins A, D, and E, cortisol, growth hormone, and insulin-like growth factor 1. All response variables were analyzed using the MIXED procedure of SAS. Calf body morphometrics and BW of the dam at calving (P ≥ 0.32), calf organ weights (P ≥ 0.21), and calf ovarian follicle counts (P ≥ 0.13) were not affected by maternal treatment. Concentrations of Se and Co in calf serum and Se in calf liver were increased (P ≤ 0.02) in VTM. Serum concentrations of Co and vitamin A in the dam were greater (P ≤ 0.01) in supplemented compared with non-supplemented dams, and serum concentrations of vitamin D were greater (P ≤ 0.0003) in supplemented dams and calves compared with the non-supplemented cohort. Maternal supplementation supported vitamin and mineral status in the neonate, yet had no discernable impact on BW, organ mass, or circulating hormones/metabolites in the calf. Evaluating offspring at later postnatal time points is warranted to determine if prenatal vitamin and mineral supplementation affects performance, health, metabolism, and efficiency of energy utilization in key metabolic tissues in the calf.

The aim of this study was to determine and compare the plasma and erythrocyte (RBCs) levels of vitamin E in cows of 3 different categories (2–3 weeks antepartum, 1–3 weeks and 2.5–3 months of lactation) and 1-month-old calves on dairy nutrition. We were interested in the degree of correlation of vitamin E in plasma and RBCs within the individual categories. Blood on EDTA was collected from 61 cows and 12 calves. As a part of the haematological examination, we determined haematocrit (HCT) immediately after the collection. We determined vitamin E from plasma and RBCs by a standard HPLC method. We compared the results of vitamin E in plasma and RBCs and correlated them. The concentration of vitamin E in the plasma and RBCs was 6.98 and 3.45 μmol/l, respectively, in cows 2–3 weeks antepartum; 1–3 weeks of lactation it was 4.98 and 3.34; 2.5–3 months of lactation 11.76 and 2.80 μmol/l; and in the case of calves 12.07 and 6.29 μmol/l. Weak correlations were observed between vitamin E in plasma and the RBC concentrations in the antepartum category R2 = 0.2076; 1–3 weeks of lactation R2 = 0.0369; 2.5–3 months of lactation R2 = 0.2403 and calves on dairy nutrition R2 = 0.4628. Vitamin E concentrations in RBCs were shown to be more stable than in plasma, where the concentrations varied. It is possible that vitamin E in RBCs could tell us more about the longer-term reserves of vitamin E in the organism. The highest concentration of vitamin E in plasma and RBCs, as well as a stronger correlation was found in calves.
