Abstract
Currently, ketosis has no fully satisfactory resolution in dairy cows. Here, we investigated the effect of levocarnitine or vitamin B complex and E with selenium on clinically ketotic cows (β-hydroxybutyrate ≥ 3.0 mmol/L and decreased milk yield), fed glycerin. In total, 18 cases of Holstein cows with clinical ketosis during the postpartum transition period were randomly assigned to three treatments (6 cases per group): (1) levocarnitine (C+G), (2) vitamin B complex and E with selenium (VBES+G), and (3) levocarnitine and vitamin B complex and E with selenium (C+VBES+G). All groups were administered glycerin. Treatments were administered daily for 4 days. Blood sampling was performed on the onset day of ketosis (day 0), day 4, and day 6. β-Hydroxybutyrate (BHBA), milk yield (MY), and serum biochemical values were measured. Half of the animals in C+G failed to overcome clinical ketosis. VBES+G treatment ameliorated BHBA (p < 0.05), MY, and glucose on day 4. However, ketosis was exacerbated following the discontinuation of the treatment. C+VBES+G treatment improved BHBA, glucose (p < 0.05), and MY and reduced ketotic cases on days 4 and 6 with greater improvements compared to the others. In conclusion, combined treatment with levocarnitine, vitamin B complex and E with selenium, and glycerin may have the therapeutic effect on clinical ketosis.

Sun X, Wang Y, Loor JJ, Bucktrout R, Shu X, Jia H, Dong J, Zuo R, Liu G, Li X, Li X. High expression of cell death-inducing DFFA-like effector a (CIDEA) promotes milk fat content in dairy cows with clinical ketosis. J Dairy Sci 2018; 102:1682-1692. [PMID: 30594378 DOI: 10.3168/jds.2018-15439] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2018] [Accepted: 10/22/2018] [Indexed: 01/11/2023]
Abstract
High blood concentrations of nonesterified fatty acids (NEFA) during ketosis represent a source of fatty acids for milk fat synthesis and explain the increase in milk fat content in ketotic cows. Cell death-inducing DFFA-like effector a (CIDEA) is a lipid droplet coat protein with important roles in the regulation of milk fat synthesis and secretion in mice. Whether ketosis alters the expression of CIDEA in mammary gland tissue and the extent to which it may contribute to regulation of milk fat synthesis and secretion are unknown. Mammary gland tissue and blood samples were collected from healthy (n = 15) and clinically ketotic (n = 15) cows. Mammary epithelial cells isolated from cows were infected with CIDEA overexpression adenovirus for 48 h, treated with 0, 0.3, 0.6, or 1.2 mM NEFA for 24 h, or infected with CIDEA-silencing adenovirus for 48 h and treated with 1.2 mM NEFA for 24 h. Serum concentrations of NEFA and β-hydroxybutyrate were greater in cows with clinical ketosis, and milk production and dry matter intake were lower in cows with clinical ketosis. However, compared with healthy cows, the content of milk fat of cows with clinical ketosis was greater. Compared with healthy cows, abundance of mRNA and protein of CIDEA, fatty acid synthase (FASN), acetyl-coA carboxylase 1 (ACACA), butyrophilin (BTN1A1), and xanthine dehydrogenase (XDH) was greater in mammary tissue of cows with clinical ketosis. Overexpression of CIDEA in cultured mammary epithelial cells increased the abundance of FASN, ACACA, XDH, and BTN1A1, and increased triacylglycerol (TAG) content in mammary epithelial cells. Exogenous NEFA increased the abundance of CIDEA, FASN, ACACA, XDH, and BTN1A1, and increased TAG content in mammary epithelial cells. Importantly, knockdown of CIDEA reversed the upregulation of FASN, ACACA, XDH, and BTN1A1 abundance and TAG content induced by NEFA treatment. Overall, these data suggest that high levels of NEFA stimulate the expression of CIDEA and enhance de novo fatty acid synthesis and milk fat secretion. As such, these mechanisms explain in part the elevation of milk fat content in dairy cows with clinical ketosis.

Abstract
The objectives of this study were to describe the onset of hyperketonemia, the number of positive hyperketonemia test results, and the duration of the longest hyperketonemic period during the first 42 d in milk (DIM) in dairy cows. Furthermore, we set out to evaluate test characteristics of single and repeated measurements of β-hydroxybutyric acid (BHBA) during this period to diagnose hyperketonemia. Using an electronic handheld meter, 252 cows from 3 farms were tested twice weekly for hyperketonemia (blood BHBA ≥1.2 mmol/L) during the first 42 DIM, resulting in 12 test results per cow (i.e., in lactation wk 0.5 to 6). Prevalence and incidence of hyperketonemia were calculated for the 12 examination days and the 42-d period, respectively. Test characteristics for the diagnosis of hyperketonemia were calculated for 4 different testing scenarios (testing all cows 1, 2, 3, or 6 times during the first 42 DIM) and 2 different gold-standard definitions (BHBA ≥1.2 mmol/L at least once during the observation period or BHBA ≥1.2 mmol/L at least twice during the observation period). Mean prevalence of hyperketonemia was 11.8%, ranging from 9.6% in lactation wk 0.5 and 2.0 to 14.6% in lactation wk 5.5. In total, 134 cows (53.2%) had at least 1 positive hyperketonemia test result during the whole 42-d period. Of these cows, 46.3% had only 1 positive result. The median first positive hyperketonemia test result was in lactation wk 2.0 [interquartile range (IQR) 1.0-3.5]. Median frequency of positive test results in cows affected by hyperketonemia was 2 positive test results (IQR 1-3). Median duration of the longest hyperketonemic period per cow affected was 1 examination interval (3-4 d; IQR 1-2). Considering a minimum of 1 positive hyperketonemia test result during the first 42 DIM as the gold standard, sensitivity of a single BHBA measurement during this period to diagnose hyperketonemia was 21%. A weekly testing protocol had a sensitivity of 72%. Specificity was 100% in both cases. Considering a minimum of 2 positive hyperketonemia test results as the gold standard, sensitivity and specificity of a single BHBA measurement during the first 42 DIM were 33 and 97%, respectively. A weekly testing protocol provided sensitivity and specificity of 91 and 83%, respectively. We conclude that the risk period for hyperketonemia lasts at least until lactation wk 6, which should be considered when planning hyperketonemia screening programs. Test characteristics of screening protocols depend on testing frequency.

Abstract
The purpose of this study was to develop a deterministic economic model to estimate the costs associated with (1) the component cost per case of hyperketonemia (HYK) and (2) the total cost per case of HYK when accounting for costs related to HYK-attributed diseases. Data from current literature was used to model the incidence and risks of HYK (defined as a blood β-hydroxybutyrate concentration≥1.2 mmol/L), displaced abomasa (DA), metritis, disease associations, milk production, culling, and reproductive outcomes. The component cost of HYK was estimated based on 1,000 calvings per year; the incidence of HYK in primiparous and multiparous animals; the percent of animals receiving clinical treatment; the direct costs of diagnostics, therapeutics, labor, and death loss; and the indirect costs of future milk production losses, future culling losses, and reproduction losses. Costs attributable to DA and metritis were estimated based on the incidence of each disease in the first 30 DIM; the number of cases of each disease attributable to HYK; the direct costs of diagnostics, therapeutics, discarded milk during treatment and the withdrawal period, veterinary service (DA only), and death loss; and the indirect costs of future milk production losses, future culling losses, and reproduction losses. The component cost per case of HYK was estimated at $134 and $111 for primiparous and multiparous animals, respectively; the average component cost per case of HYK was estimated to be $117. Thirty-four percent of the component cost of HYK was due to future reproductive losses, 26% to death loss, 26% to future milk production losses, 8% to future culling losses, 3% to therapeutics, 2% to labor, and 1% to diagnostics. The total cost per case of HYK was estimated at $375 and $256 for primiparous and multiparous animals, respectively; the average total cost per case of HYK was $289. Forty-one percent of the total cost of HYK was due to the component cost of HYK, 33% to costs attributable to metritis, and 26% to costs attributable to DA. The high total cost of HYK at reported incidences of 40 to 60% highlights the importance of appropriate transition cow nutrition and management to decrease the effect of HYK.

Abstract
Low blood glucose concentrations after calving are associated with infertility in postpartum dairy cows perhaps because glucose is a master regulator of hormones and metabolites that control reproductive processes. The hypothesis was that low blood glucose postpartum is caused by inadequate glucose entry rate relative to whole-body demand as opposed to the alternative possibility that postpartum cows have a lower regulatory set point for blood glucose. Eight early postpartum (10 to 25 d) dairy cows (5 Holstein and 3 Guernsey) were jugular catheterized. During the first 24 h, cows were infused with physiological saline at 83.3 mL/h. After 24 h, the infusion solution was switched to 50% dextrose that was infused at a rate of 41.7 mL/h (total daily glucose dose=500 g). On d 3 and d 4, the rate of glucose infusion was increased to 83.3 mL/h (daily dose=1,000 g) and 125 mL/h (daily dose=1,500 g), respectively. On d 5, physiological saline was infused at 83.3 mL/h. Blood was sampled hourly through a second jugular catheter (contralateral side) and analyzed for glucose, nonesterified fatty acids, β-hydroxybutyrate, insulin-like growth factor 1, and insulin. Blood glucose concentrations on d 1 (saline infusion) averaged 53.4±1.7 mg/dL. Blood glucose concentrations increased on d 2 when cows were infused with 500 g/d and increased further on d 3 when cows were infused with 1,000g of glucose/d. Increasing the infusion rate to 1,500 g/d on d 4 did not cause a further increase in blood glucose concentrations. Based on a segmented regression analysis, the upper physiological set point for blood glucose was 72.1 mg/dL. Both insulin and insulin-like growth factor 1 concentrations increased in response to glucose infusion and decreased when cows were infused with saline on d 5. Serum nonesterified fatty acids and β-hydroxybutyrate concentrations decreased in response to glucose infusion and rebounded upward on d 5 (saline infusion). In conclusion, early postpartum cows had circulating blood glucose concentrations that were well below the upper set point defined in this study (72.1 mg/dL). Infusing approximately 1,000 g of glucose daily increased blood glucose to the physiological set point and rapidly changed the hormonal and metabolic profile that typifies postpartum cows. The inability of the early postpartum cow to achieve an adequate entry rate for glucose relative to whole-body demand is a possible mechanism that links postpartum physiology and nutrition to reproduction in dairy cows.
