Blood lactate concentration is also frequently used as a prognostic indicator for multiple disease processes in veterinary medicine. The goals of this study were to evaluate point-of-care venous lactate concentrations in a group of cattle egrets (Bubulcus ibis) maintained in a zoo to determine if order of net capture had a significant effect on blood lactate concentrations and evaluate the association between lactate concentration and routine blood diagnostic test results. Blood samples were obtained from 10 cattle egrets housed together in a holding area as part of routine quarantine procedures. Animals were captured via net in pairs, quarantine examinations and sample collection were completed, and birds were placed in a crate for holding prior to net capture of the next pair. All birds had blood samples collected for a complete blood cell count, avian biochemistry panel, and lactate concentration. Blood lactate concentrations were obtained with the Nova Biomedical Lactate Plus point-of-care lactate meter. The mean blood lactate concentration was 12.6 mmol/L (range, 9.3-17.4 mmol/L). Capture order was not significantly associated with blood lactate concentration (P = 0.60). There was a significant positive correlation between lactate concentration and sodium (P = 0.04). There were no significant relationships between blood lactate concentration and standard complete blood cell count or biochemical values. This study found postcapture blood lactate concentrations in the cattle egrets that were unexpectedly high when compared with published avian values and found that the order in which the animal was processed in the capture event was not associated with blood lactate concentration. Further research is warranted to determine the value of blood lactate concentration trends in this species.","PeriodicalId":15102,"journal":{"name":"Journal of Avian Medicine and Surgery","volume":"39 4","pages":"190-195"},"PeriodicalIF":0.5,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145794044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over multiple measurements, the mean cloacal and skin temperatures were 41.46 ± 0.45°C (106.62 ± 0.81°F) and 40.69 ± 0.37°C (105.24 ± 0.67°F), respectively, and there was a moderate positive correlation (r = 0.552, P = 0.008) between the 2 methods. These data can be useful for evaluating the health of these endangered parrots.

It is currently labeled for use in dogs and cats to control postoperative pain and inflammation associated with orthopedic surgery, ovariohysterectomy, and castration for a maximum of 3 days. Robenacoxib has been used anecdotally in avian species at doses ranging from 2-10 mg/kg every 3-7 days to manage pain associated with inflammation in various scenarios, including treatment of proventricular dilatation disease, orthopedic pain, such as arthritis and pododermatitis, and post nail and beak trims. Robenacoxib concentrates in inflamed tissues, and its clinical effects persist longer than its short terminal half-life in blood. In this study, the pharmacokinetic parameters of a single oral dose of robenacoxib were evaluated in a group of 7 healthy, adult Hispaniolan Amazon parrots (Amazona ventralis). The results indicated that a single 4-mg/kg oral dose of robenacoxib was well tolerated without any adverse clinical effects. The mean peak plasma concentration was reached at 0.45 hours, with a peak concentration of 88.75 ng/mL. The t1/2 was 1.3 ± 0.37 hours. The mean total body clearance per fraction of dose absorbed was 24.9 L/kg/hr. Robenacoxib was not detected in any bird 6 hours postadministration. Further pharmacodynamic studies of this drug, including defining the potency of robenacoxib against avian COX-1 and COX-2 enzymes, would provide stronger support for dose determination and the effectiveness of robenacoxib in psittacine birds.","PeriodicalId":15102,"journal":{"name":"Journal of Avian Medicine and Surgery","volume":"39 4","pages":"183-189"},"PeriodicalIF":0.5,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145794069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This report represents the first published case of successful rehabilitation and release of a bald eagle (Haliaeetus leucocephalus) after complete arthrodesis of a metacarpophalangeal joint luxation. The patient was presented to the Louisiana State University Wildlife Hospital of Louisiana with a chronic, complete luxation of the left metacarpophalangeal joint and articular fracture of an unknown origin. Owing to the chronicity of the injury, a closed reduction and stabilization with conservative management were not achievable. Articular debridement and external fixation with a type 1A fixator were used to immobilize the joint. Complete anatomic reduction was not achieved; however, this did not inhibit the bird's ability to gain lift, land, and navigate in the air. Postrelease monitoring was not pursued for this patient.

This retrospective study summarizes the histologic findings of 273 toucans, 24 mountain toucans, 240 aracaris, and 64 toucanets (601 total specimens) submitted to 4 diagnostic laboratories from 1994 through January 2013. Infectious diseases were most common (53.1%, 319/601), followed by nutrition-based deposition disorders (36.4%, 219/601) and cardiovascular disease (10.3%, 62/601). Among infectious diseases, bacterial diseases were most common (57%, 182/319, including 45 cases of mycobacteriosis). Mycotic diseases (14.1%, 45/319) included ventricular candidiasis (73.3%, 33/45), aspergillosis (13.3%, 6/45), and undetermined fungus (13.3%, 6/45).

The treatment involved local debridement and supportive care, which provided temporary improvement. However, the lesion recurred multiple times, leading to the decision to perform complete surgical excision of the uropygial gland. The falcon underwent cardiopulmonary arrest during the procedure and was unresponsive to resuscitation. Histological analysis identified a compact cystic mass characterized by atypical proliferation of the keratin and squamous cell layers, consistent with an infiltrating keratoacanthoma of the uropygial gland. Additional findings included necrotizing hepatitis, focal splenic necrotic lesions and white pulp depletion, pyogranulomatous nephritis, pulmonary edema, and infiltrative chronic-active enteritis. Amphophilic intranuclear inclusion bodies were observed in the basal layer of the uropygial mass and in hepatocytes.

Interaction effects indicated that from 11 to 24 and 25 to 42 days of age, diets containing higher copper levels (16 and 32 mg/kg) combined with SYN resulted in greater body weight gain compared to diets with 8 or 16 mg/kg of copper without SYN (p<0.05). Birds fed a diet containing 8 mg/kg of Cu without SYN exhibited the highest coliform population and pH in the ileum (p<0.05). Elevated Cu levels or SYN supplementation improved intestinal morphology, particularly increasing villus surface area and the ratio of villus height to crypt depth. The total antibody titer and IgM in the serum of chickens fed a diet containing 16 mg/kg of Cu along with SYN were significantly higher compared to those fed diets containing 8 and 16 mg/kg of Cu without SYN. Meat analysis (thigh muscle) showed that the percentage of cooking loss in the meat of chickens fed diets containing 32 mg/kg of Cu with SYN was significantly lower compared to chickens fed diets containing 8 mg/kg of Cu without SYN. The inclusion of Cu-methionine chelate alongside SYN significantly improved the performance, morphology, intestinal microbial population, immune response, and meat quality of broiler chickens.
