“…Differences (P<.05) were significant only between seasons and ranches with levels higher in the wet season. Bayfield and Mylrea (1969) reported that serum vitamin E concentrations increased from 2.20 mg/100 ml in calves to 3.70 mg/100 ml in weanlings, while heifers and cows had levels between 5.40 and 9.00 rag/100 ml.…”

The nutrient status of grazing beef cattle from four selected soil order regions of Florida was examined. Liver, blood, hair and feces samples from 14 heifers and 14 cows, plus forage samples, were collected during two periods of the year from nine ranches located in four different regions. Soil samples were collected during one period. The soil order regions were the Histosol (southeast), Spodosol (southwest), Entisol (central) and Ultisol (northwest). Mean forage P values were higher (P less than .05) in the wet season, while mean hair P levels were higher (P less than .05) during the dry season. Mean forage, plasma, liver and hair Mg values were higher (P less than .05) in the wet season. Plasma vitamin E, liver vitamin A and forage carotene levels were higher (P less than .05) during the wet season. Mean forage P content was deficient (less than .25%) during both seasons and varied from .10% in the dry season to .16% during the wet season. Mean forage Mg (less than .18%) and K (less than .60%) concentrations were deficient in the dry season. Forage protein was deficient (less than 7.0%) in five of seven ranches during the dry season. Extractable soil Ca, exchangeable soil Ca, Mn, Al, H+, soil organic matter and effective cation exchange capacity were higher (P less than .05) in the Histosol region. Extractable soil K was low (60 ppm) in all regions, except the northwest. Forage P was critical (less than .25%) during the dry season in all regions and varied from .08 to .15%, while plasma P was deficient (4.5 mg/100 ml) in animals from the southeast during the dry season only.

Abstract. Three groups of beef cow and calf pairs were studied to determine plasma vitamin E and blood selenium (Se) concentrations of calves at 1 month old. Group 1 was managed on irrigated pasture and calves received no Se/vitamin E injections at birth. Group 2 was managed on irrigated pasture, and the calves were injected with Se/vitamin E at birth. Group 3 was managed on dry foothill grasslands, and these cows were supplemented with 56.3 mg vitamin E and 3 mg Se daily, and the calves received a Se/vitamin E injection at birth. The plasma concentration of vitamin E in group 1 and 2 cows (9.5 6 1.24 and 8.43 6 1.0 mg/ml, respectively) was significantly higher than that of the group 3 cows (2.28 6 0.42 mg/ml; P , 0.05). The blood Se concentrations in group 3 cows (169 6 37 ng/ml) were significantly higher than those in group 1 and 2 cows (36.4 6 15.9 and 31.1 6 12.5 ng/ml, respectively; P , 0.05). Calf Se was highly correlated to cow Se (r 5 0.965), and calf vitamin E was moderately correlated to cow vitamin E (r 5 0.605). Calf vitamin E concentrations were consistently lower than cow vitamin E concentrations, and many values would be considered deficient.

“…According to the concentration of α-tocopherol in plasma, the subclinical VE deficiency group (2-3 µg/ml α-tocopherol) and the healthy control group (>4 µg/ml α-tocopherol) were determined (10)(11)(12). Finally, after excluding all other cases of perinatal disease, 67 cows were selected as test animals.…”

“…This process makes early post-partum cows prone to subclinical VE deficiency and systemic oxidative stress. Plasma concentrations of α-tocopherol in cows at 2-3 µg/ml can be identified as subclinical VE deficiency (10)(11)(12). Vitamin E deficiency and oxidative stress are important causes of perinatal dairy cows' susceptibility to productive diseases (13).…”

Vitamin E (VE) is an essential fat-soluble nutrient for dairy cows. Vitamin E deficiency leads to immune suppression and oxidative stress and increases the susceptibility of cows to reproductive disorders in the early post-partum period. However, studies on plasma proteomics of VE deficiency have not been reported so far. Therefore, the purpose of this study was to understand the changes of blood protein profile in cows with subclinical VE deficiency in the early post-partum period. In this study, plasma protein levels of 14 healthy cows (>4 μg/ml α-tocopherol) and 13 subclinical VE-deficient cows (2–3 μg/ml α-tocopherol) were analyzed by tandem mass tag (TMT). The results showed that there were 26 differentially expressed proteins (DEPs) in the plasma of cows with subclinical VE deficiency compared with healthy controls. Twenty-one kinds of proteins were downregulated, and five kinds were upregulated, among which eight proteins in protein–protein interactions (PPI) network had direct interaction. These proteins are mainly involved in the MAPK signaling pathway, pantothenic acid and coenzyme A (CoA) biosynthesis, PPAR signaling pathway, and glycosylphosphatidylinositol (GPI)-anchor biosynthesis. The top four DEPs in PPI (APOC3, APOC4, SAA4, PHLD) and one important protein (VNN1) by literature review were further verified by ELISA and Western blot. The expression levels of APOC3, VNN1, and SAA4 were significantly lower than those of healthy controls by ELISA. VNN1 was significantly lower than those of healthy controls by Western blot. VNN1 is closely related to dairy cow subclinical VE deficiency and can be a potential biomarker. It lays a foundation for further research on the lack of pathological mechanism and antioxidative stress of VE.
