ABSTRACT It is important to investigate fast and accurate equine colic syndrome diagnostic forms. Lactate results from anaerobic glycolysis; high levels of it may indicate intestinal disorders with tissue hypoperfusion and hypoxia. The current study aims at investigating whether blood and peritoneal lactate values observed when horses with colic syndrome were hospitalized, were associated with condition type, therapeutic referral, and survival rates. Retrospective analysis was applied to 498 medical records of animals with colic syndrome, at EQUIVET Hospital -SP; 89 cases were herein selected. Based on logistic regression, peritoneal lactate played a more significant part than blood in variables like obstruction type and survival rates. Surgical cases comprised 52.8% of analyzed animals; strangulation changes, 26%; and overall survival, 62.9%. Mean blood and peritoneal lactate level in animals showing strangulation changes reached 5.11 and 7.33mmol/L, whereas non-strangulation cases recorded 3.54 and 3.06mmol/L, respectively. On the other hand, mean blood and peritoneal lactate level recorded for survivors reached 3.43 and 2.42mmol/L, whereas non-survivors recorded 4.84 and 7.13mmol/L, respectively. We concluded that peritoneal lactate measured when horses with colic syndrome were hospitalized was a predictor of condition type, and of animal survival and prognosis. However, blood and peritoneal lactate measurements did not contribute to therapeutic referral.

ABSTRACT The present study aimed to evaluate and compare the palmar and plantar digital arteries of 10 horses and 10 mules through B-mode and spectral Doppler ultrasound. Likewise, compare the plantar arteries of the pelvic limbs with the palmar arteries of the thoracic limbs, in addition to verifying the differences of the digital arteries in the contralateral limbs (right and left) in horses and mules using B-mode and spectral Doppler ultrasonography. The evaluated parameters were the diameter and the intima-media thickness (IMT), resistivity index (RI), pulsatility index (PI), peak of systolic velocity (pSV), final diastolic velocity (fDV) and mean velocity (MV) of the lateral and medial palmar and plantar arteries digital in healthy horses and mules. The horses presented higher diameters values, IMT, pSV, fDV and MV in comparison to the mules. The variables RI and PI also presented differences between horses and mules. Also, both species showed higher values in the variables of B-mode and Doppler ultrasonography in the thoracic limbs. Differences were also detected in the comparison between the limb sides (right and left) in the two modalities. The B-Mode and spectral Doppler ultrasound techniques are viable tools to identify differences in the palmar and plantar digital arteries in healthy horses and mules, highlight the differences between the thoracic and pelvic limbs and their respective sides (right and left) as well.

ABSTRACT The giant anteater (Myrmecophaga tridactyla) is classified as vulnerable to extinction. Here, we report the occurrence of ancylostomiasis in a young male Myrmecophaga tridactyla. The animal was raised from a puppy in captivity with management directed toward rehabilitation and monitored soft release. Five months after release, significant weight loss was noted in the individual, who was captured for examinations, with detection of Ancylostoma sp. in coproparasitological analysis. Although common in domestic carnivores, this is the first report of hookworm disease in free-ranging giant anteaters. Due to the stress factor arising from adapting to the challenges in the new environment, long-term post-release monitoring of animals undergoing rehabilitation is extremely important to increase the chance of survival of individuals. The giant anteater was released after treatment with vermifuge composed of fenbendazole, pyrantel pamoate, and praziquantel.

ABSTRACT This study aimed to investigate the effects of animal type, on-farm handling, and transport conditions on temperament of beef cattle pre-slaughter. The study evaluated 4,061 cattle batches, averaging 49 animals, with a total of 199,026 cattle. Temperament was evaluated through a behavioral assessment carried out based on the temperament shown by cattle when approached by humans. One of three different temperament scores were assigned to each batch: calm, anxious, or excitable. Excitable temperament was reported in animals subjected to long transport time and distance and high loading density. The degree of carcass fatness was higher in calm animals, followed by anxious animals, with the excited temperament animals having the lowest carcass fatness degree. Older animals showed more excitable temperament, while younger animals showed calmer temperament. The excitable temperament was more evident in horned animals in relation to polled animals. Animal temperament was more reactive in batches with older cattle, low carcass fatness degree, and with more than 20% horned animals. Good handling and loading facilities and procedures at the farm contributed to adequate cattle temperament expression prior to slaughter.

ABSTRACT The body weight (BW) of an animal is a vital economic trait that might help in decision-making in the handling of animals. The objective of the present study was to develop equations for the prediction of BW in Pelibuey sheep using scrotal circumference (SC). The BW (23.40 ± 6.96 kg) and SC (20.25 ± 6.19 cm) have been recorded in 405 male Pelibuey at the Southeastern Center for Ovine Integration, Mexico. Linear, logarithmic, quadratic, exponential, cubic, and power regression models were used for data analysis. Pearson correlation (R), Coefficient of determination (R2), Adjusted coefficient of determination (Adj.R2) Root mean square error (RMSE), Akaike information criterion (AIC), and Bayesian information criterion (BIC) were used to select the best model. Power regression model showed the highest R (0.93), R2 (0.86), Adj.R2 (0.86) and lowest RMSE (0.02), AIC (-989.44) and BIC (-981.44). The current study suggests that SC might be used as the only predictor for BW of growing Pelibuey sheep raised under tropical conditions.

ABSTRACT Partial or complete bladder eversion is a rare condition of poor prognosis in cows, commonly associated with intense tenesmus observed in the peripartum period. A 14-year-old obese Nellore cow at 280 days of gestation was referred with 24-hour bladder prolapse. The bladder was complete eversion through the vulvar vestibule showing a thick congested wall and small residual urine volume. After clinical examination, the cow received scopolamine butylbromide and intercoccygeal epidural anesthesia, and the externalized bladder segment was partially reduced, remaining only 10 cm externalized. The cow was maintained with an intravesical human gastric tube number 16 and constant monitoring. The eversion was fully reduced after 12 hours of local treatment, and as the cow presented subclinical ketosis, hypocalcemia and cystitis, antibiotic, glucose, calcium and propylene glycol therapy were performed. We opted for induction of parturition, and after 24 hours, a healthy 52kg calf was born and the placenta was delivered 16 hours after calving. The cow and calf were discharged on the sixth day of hospitalization, with no recurrences or secondary complications after treatment.

ABSTRACT The objective was to investigate the feeding behavior of sheep in marandu grass (Brachiaria brizantha cv. Marandu) pastures under continuous stocking with the same average height and different horizontal structures. The treatments were composed of less heterogeneous pastures (P-H, 24% coefficient of variation of plant heights and more heterogeneous pastures (P+H, 46% coefficient of variation of plant heights) and the locations of the picket, front and back, were also evaluated. A randomized block design was used, with split plots in space and four replications in two years. Crossbred lambs were used, managed under continuous stocking and variable stocking rate, to maintain average height of pastures at 30 cm. Greater masses of total forage, live leaf, live stem and dead material, and greater time of sheep in rumination, occurred in the front, in relation to the paddock background. In P-H, grazing time (GT) did not vary between regions. In P+H, GT was lower at the front than at the background. Idle time (IT) was similar between P-H and P+H. However, the animals remained more IT in the front than in the background. The feeding behavior of grazing sheep is modified in marandu grass pastures under continuous stocking with the same average height, but with different spatial variability of the vegetation.

ABSTRACT A study was designed to compare two sedation protocols to be used in horses undergoing orchiectomy when standing. In both protocols, the induction to the sedative state was performed with bolus detomidine at a dose of 10 µg/kg, intravenously (IV). In the first protocol (eight horses), the sedative state was maintained with 1% glyceryl guaiacol ether (GGE) in continuous infusion, at a dose of 1ml/kg/hour IV. In the second protocol (eight horses) this sedative effect was maintained with detomidine in continuous infusion at the same dose and induction route. Orchiectomy was performed on all animals. The two protocols allowed the surgeries to be performed when standing. However, horses kept under sedation by the GGE showed greater relaxation and a more intense degree of sedation. It should be noted that the use of GGE to maintain the sedative state in horses is unprecedented in the literature. The drug is used in anesthetic protocols in the species, but only in pre-anesthetic medication in general anesthesia. It was concluded that the two sedation protocols allowed the performance of orchiectomy with the horses when standing. However, the protocol in which 1% GGE was used showed more profound sedation, without adverse effects.

ABSTRACT Artisanal cheese production involves a centuries-old tradition in the state of Minas Gerais in Brazil, playing an important historical and social role. The aim of this study was to evaluate the characteristics of artisanal Minas cheeses from seven regions certified for their production in relation to their physical-chemical and centesimal composition to identify parameters that are useful to differentiate them. There were differences among the cheeses from different regions for the soluble nitrogen variables, extension and depth of ripening indexes, ash, oxidation, fat and pH. The highest values for the ripening length and depth index were observed in the Cerrado region. The cheeses from the Canastra region were different due to the higher moisture content, and the cheeses from Campo das Vertentes presented higher pH and nitrogen compound values. Despite the similarities among cheeses in each region, they had dispersed positions in the principal components analysis. There are differences in the physicochemical and centesimal composition among the artisanal Minas cheeses from the distinct regions in Minas Gerais, and the analyzed parameters can be used to differentiate them. The contents of ash, fat, oxidation index, soluble nitrogen and pH were the parameters that were associated with greater differences in cheeses.
摘要巴西米纳斯吉拉斯州的手工奶酪生产有着数百年的传统，在历史和社会上发挥着重要作用。本研究的目的是评估来自七个生产认证地区的手工米纳斯奶酪的物理化学成分和百分含量特征，以确定有助于区分它们的参数。不同地区的奶酪在可溶性氮变量、成熟度和深度指数、灰分、氧化度、脂肪和pH值方面存在差异。在塞拉多地区观察到成熟长度和深度指数的最高值。Canastra地区的奶酪由于水分含量较高而有所不同，Campo das Vertentes的奶酪具有较高的pH值和氮化合物值。尽管每个地区的奶酪有相似之处，但它们在主成分分析中的位置分散。米纳斯吉拉斯不同地区的手工米纳斯奶酪在理化成分和百分含量方面存在差异，分析的参数可用于区分它们。灰分、脂肪含量、氧化指数、可溶性氮和pH值是奶酪差异较大的参数。

The aim of this study was to evaluate the characteristics of artisanal Minas cheeses from seven regions certified for their production in relation to their physical-chemical and centesimal composition to identify parameters that are useful to differentiate them. There were differences among the cheeses from different regions for the soluble nitrogen variables, extension and depth of ripening indexes, ash, oxidation, fat and pH. The highest values for the ripening length and depth index were observed in the Cerrado region. The cheeses from the Canastra region were different due to the higher moisture content, and the cheeses from Campo das Vertentes presented higher pH and nitrogen compound values. Despite the similarities among cheeses in each region, they had dispersed positions in the principal components analysis. There are differences in the physicochemical and centesimal composition among the artisanal Minas cheeses from the distinct regions in Minas Gerais, and the analyzed parameters can be used to differentiate them. The contents of ash, fat, oxidation index, soluble nitrogen and pH were the parameters that were associated with greater differences in cheeses.","PeriodicalId":8393,"journal":{"name":"Arquivo Brasileiro De Medicina Veterinaria E Zootecnia","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42737240","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}
