Abstract
Cytokines are important markers for immune activation, regulation, and homeostasis. The lack of monoclonal antibodies (mAbs) and sensitive assays to evaluate cytokine secretion has hindered research of bovine inflammation and immune regulation. We recently developed a fluorescent bead-based multiplex assay (multiplex assay) for bovine IL-10, TNF-α, and IFN-γ. Although the original assay covers a broad concentration range for the 3 targets, analytical sensitivity for IL-10 and IFN-γ could be improved to facilitate detection of these cytokines in their physiological low pg/mL range. To optimize the multiplex assay, we generated a new bovine IL-10 mAb and explored its use for the detection of intracellular and secreted bovine IL-10. The new bovine IL-10 mAb 130 recognized recombinant bovine IL-10 fusion protein and did not react with the fusion protein tag, or the TNF-α and IFN-γ standards in the multiplex assay. For improving IFN-γ detection, we explored cross-reactivity of anti-equine IFN-γ mAbs by intracellular staining of bovine stimulated peripheral blood mononuclear cells (PBMC). Equine IFN-γ mAb 3 showed excellent cross-reactivity with bovine IFN-γ by intracellular detection. Adding IL-10 mAb 130 and IFN-γ mAb 3 to the bovine multiplex assay substantially improved the analytical sensitivity with lower limits of detection in the low pg/mL range for all analytes. The detection ranges for the optimized multiplex assay were determined as 2 - 134,000 pg/mL for IL-10, 8 - 127,000 pg/mL for IFN-γ, and 12 - 193,000 pg/mL for TNF-α. The assay was next used to measure cytokine concentrations in cell culture supernatants from PBMC stimulated in plasma from whole blood stimulation to confirm native IL-10, TNF-α, and IFN-γ recognition and to explore the upper detection limits of the assay. In PBMC stimulation with a mix of phorbol myristate acetate (PMA) and ionomycin resulted in highest cytokine concentrations, while in plasma from whole blood stimulation, highest concentrations were observed in samples stimulated with a mix of lipopolysaccharide (LPS), phytohemagglutinin (PHA), and the TLR-2/6 agonist Pam2Csk4. PBMC and whole blood stimulation protocols showed that the optimized multiplex assay covers a wide linear detection range for measuring cytokine concentrations in bovine samples. For whole blood stimulation, a cocktail of pathogen associated molecular patterns elicited a stronger cytokine response than a mix of PMA and ionomycin, but response varied considerably between individual cattle. In conclusion, optimizing the bovine cytokine assay with new reagents improved the lower detection limits and widened the linear detection ranges while lowering the background of the multiplex assay.

J Dairy Sci 2024:S0022-0302(24)00631-3. [PMID: 38554819 DOI: 10.3168/jds.2023-24280] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Accepted: 02/25/2024] [Indexed: 04/02/2024]
Abstract
Amputation dehorning (AD) is a common practice performed on calves, causing harmful effects such as pain, distress, anxiety, and fear. These effects extend to behavioral, physiological, and hematological responses, prompting serious ethical concerns regarding animal welfare, even when performed with local anesthesia. Meloxicam, a non-steroidal anti-inflammatory drug, has been widely used to mitigate the side effects of dehorning and disbudding in calves. However, there is a notable gap in research regarding the effects of meloxicam on calves aged 6 weeks to 6 mo undergoing AD procedures. This study was designed to assess the effectiveness of co-administering meloxicam with lidocaine, a cornual nerve anesthetic, in alleviating the adverse effects caused by the AD procedure in calves within this age range, compared with the use of lidocaine alone. Thirty Holstein calves were enrolled and randomly divided into 2 groups. The first group (Placebo) received a subcutaneous injection of 5 mL of lidocaine in the horn area and a subcutaneous injection of 0.9% saline at a dose of 0.025 mL/kg in the neck, administered 10 min before the AD procedure. The second group (MX) received a combination of lidocaine and meloxicam: a subcutaneous injection of 5 mL of lidocaine in the horn area and a subcutaneous injection of 20 mg/mL meloxicam at a dose of 0.025 mL/kg in the neck, also administered 10 min before the AD procedure. To avoid subjective bias, the researchers were blinded to the treatment groups. Pain-related behaviors, including tail flicking, head shaking, ear flicking, head rubbing, head crossing bar, and kicking, were observed, and physiological parameters, including heart rate, rectal temperature, respiration rate, mechanical nociceptive threshold (MNT), daily active steps, and food intake were monitored. Hematological conditions were determined using enzyme-linked immunosorbent assays and routine blood tests. The data were processed using a generalized linear mixed model (GLMM). The outcomes demonstrated that the AD procedure increased the frequencies of ear flicking and resulted in rises in the respiration rate, heart rate, rectal temperature, and daily active steps. It also led to decreases in total food intake, forage intake, hay intake, MNT, and increased concentrations of prostaglandin E2 (PgE2), interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), nitric oxide (NO), and malondialdehyde, as well as glutathione peroxidase activity. However, calves that received meloxicam treatment showed significant improvements in response to the AD procedure, including lower respiration rates, heart rates, and rectal temperatures; higher MNTs; and lower intermediate cell ratio. They also had higher red blood counts, hemoglobin levels, hematocrit values; larger mean platelet volumes; and lower concentrations of PgE2, IL-1β, TNF-α, and NO. These results suggest that co-administration of lidocaine and meloxicam may aid in mitigating the adverse impacts induced by the AD procedure on these calves, thereby supporting the use of meloxicam in conjunction with a local anesthetic in AD procedures for calves aged 6 weeks to 6 mo.

Prevention of umbilical outpouchings and mortality in pigs: Meloxicam, tying, cutting, and chlorhexidine versus amoxicillin or no treatment? A clinical field trial. Porcine Health Manag 2024; 10:10. [PMID: 38365774 PMCID: PMC10874036 DOI: 10.1186/s40813-024-00358-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2023] [Accepted: 01/19/2024] [Indexed: 02/18/2024] Open
Abstract
BACKGROUND Umbilical outpouchings (UOs) are common in Danish pigs. Neonatal antibiotics are therefore used with the hope of reducing umbilical infections and subsequently UOs. However, the effect of neonatal antibiotics on preventing UO has been the subject of mixed conclusions, and secondly, treating all animals with antibiotics might exacerbate the development of antimicrobial resistance. This study analysed the effects of different treatments on the prevalence of umbilical outpouchings and mortality from birth to nursery unit. All treatment was on the day of birth. The groups were: a negative control group, an antibiotic group receiving amoxicillin, and an experimental group where the piglets had their umbilical cord disinfected with chlorhexidine, followed by tying and clipping, and lastly, injection with meloxicam. The pigs were examined six weeks after weaning, and all pigs that died during the study were autopsied. RESULTS There were 5494 pigs divided across the three groups. There were no statistically significant differences in UO prevalence between the groups: control 3.9%, antibiotic 4.2%, and experimental 4.0% (p = 0.87). The only variable affecting the prevalence of UOs in this study was sex with females being at higher risk. There were no statistically significant differences in mortality between the groups from birth until departure from the nursery unit: control 22.9%, antibiotic 21%, and experimental 21.4% (p = 0.33). The variables affecting mortality were sex, intrauterine growth restriction (IUGR), birth weight, and cross fostering. Males had higher odds of dying, as had piglets recorded with some degree of IUGR. Also, low birth weight increased the odds of dying for all weight quartiles compared to the fourth (the heaviest piglets > 1.6 kg), as well as cross fostering increased the odds ratio of dying. CONCLUSIONS This study found no significant differences in the prevalence of UOs and mortality following different treatments at birth. The study showed that the prevalence of UO and mortality was not reduced following the administration of amoxicillin or meloxicam in combination with disinfection and tying of the umbilical cord.

The impact of freezing and multiple freeze-thaw cycles on Brix refractometry estimates of immunoglobulin concentration in beef cattle colostrum. CANADIAN JOURNAL OF VETERINARY RESEARCH = REVUE CANADIENNE DE RECHERCHE VETERINAIRE 2023; 87:146-152.

Abstract
Evaluation of immunoglobulin G (IgG) concentration in colostrum is important to guide on-farm management. Studies have shown that digital Brix refractometry accurately estimates colostrum IgG concentration in both dairy and beef cattle colostrum. Colostrum is often frozen in both clinical and research settings. The implications of this freezing on the accuracy of Brix refractometry measurements are largely unknown. The first objective of this study was to evaluate the agreement between digital Brix percentage measurements of IgG in beef cattle colostrum taken before and after different durations of freezing. The second objective was to evaluate the effects of multiple freeze-thaw (FT) cycles on Brix percentage measurements of IgG in beef cattle colostrum. There was good agreement between Brix percentages in fresh colostrum and after short (2 to 8 d), medium (4 to 7 mo), and long (3 y) periods of freezing (concordance correlation coefficient: 0.95, 0.96, and 0.96, respectively). Although there was no significant change in mean Brix percentages over 2 FT cycles (P > 0.05), mean Brix percentages decreased with 3 FT cycles (P = 0.017). Samples from the fourth and fifth FT cycles were observably coagulated, and these measurements were therefore deemed inaccurate. Data from this study indicate that freezing had minimal impact on digital Brix refractometer estimates of IgG concentration in beef cattle colostrum, but that samples stored for future testing should not undergo more than 2 FT cycles.

Impact of Meloxicam Administration in Cows Prior to Caesarean Section on the Efficacy of Passive Immunity Transfer in Calves. Animals (Basel) 2022; 13:ani13010037. [PMID: 36611647 PMCID: PMC9817769 DOI: 10.3390/ani13010037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2022] [Revised: 12/18/2022] [Accepted: 12/20/2022] [Indexed: 12/24/2022] Open
Abstract
The objective of this study was to assess in the Charolais cow−calf system, the benefit of meloxicam administered to cows prior to c-section to the efficacy of passive immune transfer to the newborn under the assumption that providing analgesia to the dam could lead to an earlier or longer colostrum intake. This study was performed in Burgundy, France in two veterinary private practices. Colostrum quality, delay between the end of the c-section and the first spontaneous colostrum suckling, and the 24 h after birth calf serum IgG content from cows treated 15 min prior to c-section with meloxicam subcutaneously (0.5 mg/kg) (n = 22) or without analgesia (n = 26) were compared. No significant differences were observed in the quality of the colostrum nor the delay between the end of the surgery and the first spontaneous colostrum suckling between treatment groups. However, the number of calves showing a better transfer of passive immunity (IgG content >15 g/L) was significantly higher (p = 0.023) among those originating from dams receiving meloxicam prior to c-section. This effect was notably observed in multiparous cows (p = 0.041). This study confirms that pre-emptive analgesia in cows prior to c-section benefits the calf through an improved colostrum intake that is of paramount importance for calf short- and long-term survival.

Abstract
The RNA concentration in sEV isolated from bovine colostrum was highest using the combination of the miRCURY Cell/Urine/CSF and miRNeasy Mini kits. The top 50 miRNA were the same using miRDeep2 and sRNAbench, predominated by let-7b, let-7a-5p, miR-30a-5p, and miR-148a. Predicted target genes of the top 50 miRNA regulate PI3K-Akt and MAPK signaling pathways, axon guidance, and focal adhesion. The abundance of miR-27a-3p was higher in colostrum with high IgG concentrations.
The consumption of bovine colostrum by newborn calves during the first days of life is essential to ensure the transfer of passive immunity. In addition to critical IgG, colostrum also contains non-IgG biomolecules, including microRNA (miRNA). The present study investigated the profiles of miRNA in small extracellular vesicles (sEV) isolated from bovine colostrum with high (256.5 ± 5.7 mg/mL, mean ± standard deviation, n = 4) and low (62.8 ± 3.6 mg/mL, n = 4) concentrations of IgG. Different combination of sEV extraction methods and bioinformatic pipelines (miRDeep2 and sRNAbench) for miRNA analysis were evaluated. Results showed that miRCURY exosome Cell/Urine/CSF and miRNeasy Mini kits yielded the highest RNA concentration. The miRNA-seq data analysis showed miRDeep2 yielded more comprehensive miRNAome compared with sRNAbench (527 versus 392 unique miRNA), whereas 389 shared miRNA were identified using both approaches. The profiles of top 50 miRNA were the same using both approaches, and their abundance contributed to 91.7% and 94.3% of total abundance of miRNA using miRDeep2 and sRNAbennch, respectively. These core miRNA were predicted to target 2,655 genes, which regulate 78 KEGG (Kyoto Encyclopedia of Genes and Genomes) level-3 pathways including PI3K-Akt and MAPK signaling pathway, axon guidance, and focal adhesion. The expression profiles of sEV-associated miRNA were similar between high- and low-IgG colostrum samples, despite the fact that the abundance of miR-27a-3p was higher in colostrum with high concentrations of IgG. In conclusion, a core miRNAome in bovine colostrum may play a role in regulating health and developmental stages in neonatal calves, independent of IgG concentration.

Abstract
Background Pain in cattle is a major welfare problem, as cattle mask their pain. Subjective and objective parameters to assess pain in cattle have been described. Among the objective parameters to evaluate pain in cattle is substance P (SP). SP is a neurotransmitter, which is involved in the processing of noxious information to the brain; it seems to be a more objective indicator for nociception than cortisol, which has long been used as a biomarker for pain and stress in cattle. The objective of this systematic review was to assess the existing literature about SP during painful procedures, conditions, and diseases in cattle in form of a systematic review. Results Following the PRISMA statement, 36 out of 236 studies were included in this systematic review. Study design, grouping, age and weight of animals, processing of blood samples for the assessment of SP, and results were heterogenous. The largest number of studies originated from the United States of America and Canada and were published in 2018. A higher number of studies were done on calves (69.4%, n = 25) compared with adult cattle (30.6%, n = 11). Most studies were done to assess SP concentrations after administration of analgesics prior to husbandry procedures in calves. Conclusions There is a manageable number of studies assessing SP concentrations during painful procedures, conditions, and diseases in cattle. SP seems to be a suitable biomarker for nociception in cattle, but results of research work are heterogenous, and SP concentrations of calves and adult cattle differ throughout studies. Basic research work is missing and is needed to assess factors others than nociception which might influence the SP concentrations in the blood plasma.

Vet World 2022; 15:981-985. [PMID: 35698526 PMCID: PMC9178569 DOI: 10.14202/vetworld.2022.981-985] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2021] [Accepted: 03/11/2022] [Indexed: 11/16/2022] Open
Abstract
Background and Aim: Calves have increased morbidity and mortality rates after dystocia. One cause is pain during birth, which reduces their colostrum intake. The administration of nonsteroidal anti-inflammatory drugs (NSAIDs) may break this causality. This study aimed to determine the consequences of a single administration of the NSAID meloxicam to dystocia calves after birth.
Materials and Methods: Fifty Holstein–Friesian calves born with dystocia from four dairy cattle farms were included in this study. The animals were randomized into two groups. The animals in Group I (n=25, treatment group) received subcutaneous 0.5 mg meloxicam/kg body weight 2-8 h after birth. The animals in Group II (n=25, control group) received a control substance (Amynin®, bovine infusion solution, Merial) with the same volume. The newborn calves were clinically examined on the 1st and 10th days of life. The information regarding the days in between was gathered by questioning the farmer.
Results: There was a significant difference (p=0.04) only in calves with thin, mushy fecal consistency on the 10th day in the treatment group compared with the control group. Moreover, meloxicam had no effect on dystocia calves.
Conclusion: Since NSAID administration did not produce a significant clinical effect, its necessity is questionable. Further studies should examine how modifying its application time would have an effect. The primary indicators of well-being, such as pain indicators in the blood, were not measured; however, these should be considered in subsequent studies.

Abstract
A promising strategy to improve newborn calf survival could be the administration of nonsteroidal antiinflammatory drugs (NSAID) especially in cases of low vitality calves born from difficult calvings. The objective of this clinical trial was to determine the effect of a single-dose meloxicam treatment [target dosage = 0.5 mg/kg ad usum veterinarium (A.U.V.) injection] on parameters of lying behavior of Holstein-Friesian dairy calves (n = 180) born to eutocic (n = 98) compared with dystocic dams (n = 82). Animal-based measures included newborn calf vitality (low, 1-6 scores; normal, 7-12 scores, scored immediately after birth), calf sex and birth weight, parity of the dam, and early maternal behavior (the time spent licking the calf). Parameters of the complex lying behavior were recorded during the first 48 h after delivery and included (1) the time spent standing, (2) lying down frequency, (3) the longest standing bout, (4) the average duration of standing bouts, (5) the first successful standing, and (6) the first attempt to stand. None of the parameters related to lying behavior were influenced by the parity of the dam, calf sex, or birth weight and maternal grooming behavior. The latency and the first attempt to stand were not influenced by the NSAID treatment; however, the time spent standing, the longest standing bout, and the average duration of standing indicated increased standing ability of meloxicam-treated calves with low vitality, but not in normal-vitality calves. The latency to stand and first attempt to stand were both increased by dystocia. Based on the present findings, sensory measurement of parameters of lying behavior during the immediate neonatal period might be useful to evaluate the efficiency of NSAID protocols. A single-dose meloxicam treatment showed considerable promise for improving standing ability of low-vitality calves.

Abstract
Dystocia is a leading cause of calf mortality, yet there is little available information quantifying the duration and forces applied to assisted deliveries. Objectives of this study were to: (1) develop a method to measure the magnitude and duration of various forces applied to a calf during calving assistance, and (2) quantify the forces applied to beef calves during manual or mechanical calving assistance. Twenty-five primiparous dams requiring calving assistance were enrolled. Calvings were assisted by manual (1 or 2 people pulling) or mechanical (calf extractor) delivery. A set of modified obstetric chains with integrated force measuring devices (Calving Assistance Force Logger; CAF-Log) were applied to the calf for delivery. The CAF-Log system was calibrated using known masses ranging from 25 to 200 kg in increasing increments of 25 kg. Duration of the assisted delivery and force parameters (peak force applied to one leg, peak force applied to both legs, cumulative force, and maximum jerk force) were described and assessed for their associations with method of delivery and ranch. Median duration was 112.6 s (IQR: 88.4–149.7) for manual and 312.6 s (IQR: 221.6–462.3) for mechanical deliveries. Mean peak force applied to one leg was 56.9 kg (SD: 22.9) for manual and 126.8 kg (SD: 48.2) for mechanical deliveries. Mean peak force applied to both legs was 95.4 kg (SD: 34.1) for manual and 188.6 kg (SD: 83.9) for mechanical deliveries. Median cumulative force was 178.3 kg min (IQR: 21.1–38.8) for manual and 380.6 kg min (IQR: 252.1–581.3) for mechanical deliveries. The maximum jerk force for manual deliveries was 36.6 kg/s (IQR: 21.1–38.8) and 77.2 kg/s (IQR: 60.9–97.1) for mechanical deliveries. An interaction occurred between ranch and method of delivery for peak force applied to one leg, peak force applied to both legs, and cumulative force. The CAF-Log system demonstrated that significantly greater forces were applied to mechanically delivered calves compared to manually delivered calves and could be used in future studies to investigate forces applied to a calf during calving assistance and their impacts on cow and calf well-being.

J Vet Intern Med 2020; 34:1662-1673. [PMID: 32463548 PMCID: PMC7379009 DOI: 10.1111/jvim.15805] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2020] [Revised: 05/01/2020] [Accepted: 05/01/2020] [Indexed: 12/15/2022] Open
Abstract
Background Brix refractometry can be used to assess colostral immunoglobulin G (IgG) concentration, but studies identifying Brix percentages to detect high‐ and low‐IgG colostrum are lacking for beef cows and interlaboratory agreement is unknown. Objectives Evaluate Brix refractometer performance and interlaboratory agreement for assessing beef cow colostrum IgG concentration, including determination of thresholds to identify colostrum containing IgG concentrations <100 g/L and ≥150 g/L. Animals Beef cows (n = 416) from 11 cow‐calf operations in Alberta, Canada. Methods Colostral IgG concentrations were measured using radial immunodiffusion (RID) and estimated by Brix refractometry for this retrospective study. Spearman correlation coefficients were assessed between RID and Brix refractometry. Likelihood ratios and misclassification cost‐term analysis were used to determine optimal Brix percentages for detecting colostrum containing IgG concentrations <100 g/L and ≥150 g/L. Concordance correlation coefficient (CCC) and Bland‐Altman analyses were performed for Brix percentages obtained at 3 different laboratories. Results Brix percentages obtained at 3 laboratories were positively correlated with IgG results (r = 0.72, 0.68, and 0.76, respectively). Colostrum Brix percentages of <24% and ≥30% were optimal for indicating IgG concentrations of <100 g/L and ≥150 g/L, respectively. Interlaboratory agreement was substantial, with CCC ranging from 0.89 to 0.96 and Bland‐Altman analysis showing small mean differences (−1.2% to 0.09% Brix) and narrow limits of agreements (−4.8% to 2.4% Brix) among laboratories. Conclusions and Clinical Importance Brix refractometry shows good potential for reliably estimating IgG concentrations in beef cow colostrum across multiple laboratories and can be recommended to aid colostrum management decisions on farms.

A randomised controlled trial investigating the effects of administering a non-steroidal anti-inflammatory drug to beef calves assisted at birth and risk factors associated with passive immunity, health, and growth. Vet Rec Open 2019; 6:e000364. [PMID: 31673377 PMCID: PMC6803011 DOI: 10.1136/vetreco-2019-000364] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2019] [Revised: 09/03/2019] [Accepted: 09/13/2019] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND The objectives of this study were to investigate the impact of pain mitigation at birth to assisted beef calves and determine the risk factors associated with transfer of passive immunity (TPI), health, and growth. METHODS Two hundred and thirty cow-calf pairs requiring calving assistance were enrolled. Calves were randomised to receive meloxicam (0.5 mg/kg) or an equivalent volume of placebo subcutaneously at birth. Calf blood samples were collected between one and seven days of age to determine serum immunoglobulin (IgG) concentration. Colostrum intake, treatment for disease, mortality, and weaning weights were recorded. Multilevel linear or logistic regression models were used to determine the effects of meloxicam and to identify risk factors. RESULTS There was no effect of meloxicam on serum IgG concentrations, average daily gain (ADG), or risk of inadequate TPI (serum IgG concentration <24 g/l), treatment for disease, or mortality (P>0.05). Bottle or tube feeding calves were associated with decreased serum IgG concentrations (P=0.01) compared with nursing. Calves with an incomplete tongue withdrawal reflex had higher odds of being treated for disease compared with those with complete withdrawal (P=0.009). Being born meconium-stained and having decreased serum IgG concentrations were associated with an increased risk of mortality (P=0.03). Being born of a mature cow, having a higher birth weight, and increased serum IgG concentrations were associated with greater ADG to weaning (P<0.05). CONCLUSION Vigour assessment at birth along with good colostrum management may be important to improve TPI and health in high-risk calves such as those assisted at birth.
