Abstract The nutritional status of dogs is a prominent theme nowadays because it is considered one of the five vital parameters of animals. There are several techniques that allow diagnosing disorders or disturbances in the body condition of these patients. Although it has some subjectivity, as it is a visual and palpation evaluation, the body condition score (BCS) is the most used for this purpose. The present study evaluated radiographic, sonographic and anthropometric measurements of subcutaneous fat deposited in the dorsal region over the seventh lumbar vertebra of 100 dogs, compared to a double-blind classification of patients on the numerical scale of the BMC. There was a positive correlation of the sonographic measurements with the body condition score (p-value below 2 x 10-16 and R = 0.54) and the same was observed with the radiographic measurements (p-value below 2 x 10-16 and R = 0.56) and anthropometric evaluations (whose p-value ranged from 1.55 x 10-7 to 2.34 x 10-11 and its R was 0.24 to 0.36). With this, it was possible to identify greater intensity in the relationship of imaging exams with ECC. It is concluded that radiography and ultrasonography have great potential for use in clinical routine as a more accurate and affordable way to diagnose nutritional disorders. This is the first study to use such equipment together with imaging tests to contribute to the early diagnosis of changes in nutritional status and promote improvements in the follow-up of weight gain or weight loss programs.
摘要 狗的营养状况是当今一个突出的主题，因为它被认为是动物的五个重要参数之一。有几种技术可以诊断这些患者身体状况的紊乱或失调。身体状况评分（BCS）是最常用的诊断方法，但由于它是通过视觉和触诊进行评估，因此具有一定的主观性。本研究对 100 只狗第七腰椎背侧沉积的皮下脂肪进行了放射学、声波图和人体测量学测量，并与根据 BMC 数字量表对患者进行的双盲分类进行了比较。超声波测量结果与身体状况评分呈正相关（p 值低于 2 x 10-16，R = 0.54），与放射学测量结果（p 值低于 2 x 10-16，R = 0.56）和人体测量评估结果（p 值在 1.55 x 10-7 到 2.34 x 10-11 之间，R 值在 0.24 到 0.36 之间）也呈正相关。由此可见，影像学检查与 ECC 的关系更为密切。结论是，放射成像和超声波成像作为一种更准确、更经济的诊断营养失调的方法，在临床常规应用中具有很大的潜力。这是第一项将此类设备与成像检查结合使用的研究，有助于早期诊断营养状况的变化，并促进改善体重增加或体重减轻计划的后续工作。

This study aimed to assess how maternal nutrition in the final third of gestation affects progeny weight performance and body composition. Forty-one steers were included, born to cows subjected to different nutritional levels during this period: 13 cows without supplementation and under nutritional restriction (RES), 16 cows supplemented to meet 100% of requirements (REQ), and 12 cows supplemented to meet 150% of requirements (HIGH). The study design was completely randomized. Progeny performance was not influenced by maternal nutrition during gestation (P > 0.05). However, RES animals excelled during challenging periods, while REQ and HIGH animals performed better in nutritionally favorable environments. Maternal nutrition in the final third of gestation did not impact the contribution of non-carcass components (16.42%) and internal organs (3.17%). RES and HIGH steers had a higher relative weight of the rumen (2.48%) compared to REQ steers (2.24%), resulting in a greater proportion of the gastrointestinal tract (8.25% vs. 7.63%). Carcass characteristics did not differ significantly between treatments (P > 0.05), with an average hot carcass weight and yield of 304.28 kg and 57.80%, respectively. The primary fore, side, and hind cuts represented 39.22%, 10.64%, and 50.67% of the carcass, respectively. Overall, maternal nutrition during gestation affects fetal development, leading to modifications in body composition and, consequently, the productive potential of the offspring.

Abstract The aim was to evaluate the effect of replacing ground corn with spineless cactus from two species Orelha de Elefante Mexicana-OEM (Opuntia stricta Haw.) and Gigante (Opuntia ficus-indica Mill) in a total mixed ration for finishing lambs evaluating its effects on intake, ingestive behavior, performance, carcass traits, commercial cuts and physiochemical composition of the meat. Eighteen crossbred lambs with average body weight of 15.0 ± 2.32 kg were distributed in a completely randomized design with three treatments (OEM and Gigante spineless cactus and ground corn as control treatment) and six replications. Spineless cactus species replacing ground corn in lambs diets does not change the intake of dry matter (DMI), crude protein and neutral detergent fiber or time (min/d) of ingestion, rumination and idleness, or final body weight gain. Lambs fed with ground corn and "Gigante" cactus presented a higher total weigh gain (TWG) and average daily weight gain (ADG) when compared to OEM spineless specie. Ground corn diet promoted better hot and cold carcass yield in lambs receiving spineless cactus, regardless of species. Feed and total costs (kg/lamb) were higher for the ground corn diet. The replacement of ground corn with spineless cactus did not change moisture, protein, and ash meat contents, as well as water holding capacity, cooking loss, shear force, and a* color intensity. However, there was an effect for the meat lipid content, b* and L* color intensity and color index, where the species of cactus Gigante on ground corn presented the highest lipid content and yellowness (b*) intensity and lower L* color compared to OEM. Spineless cactus species Gigante can replace ground corn as a source of energy in diets for finishing lambs because it significantly improves the financial income for the producer without changing the ADG, DMI, ingestive behavior and yield of commercial cuts.

Abstract The aim of this study was to determine the resistance of gastrointestinal nematodes in goats and sheep to the anthelmintic drugs levamisole, ivermectin, and albendazole in the metropolitan region of São Luís Island, Maranhão, Brazil. Fecal samples were collected from 150 animals across four different farms; two farms had goats, and the other two had sheep. The samples were then randomly divided into three to four groups of 10 animals: Group I: control, without treatment; Group II: ivermectin treatment; Group III: levamisole treatment; and Group IV: albendazole treatment. Stool samples were collected from the rectal ampulla one day before treatment and 10 days after anthelmintic treatment. Individual coproparasitological examinations were performed using the modified McMaster technique at the Animal Health Laboratory of the Federal Institute of Maranhão, Campus São Luís-Maracanã. The efficacies of the anthelmintic drugs against gastrointestinal nematodes in goats and sheep were: 14.28%, and 13.6% for ivermectin; 0% and 79.4% for levamisole; and 59.8% and 3.43% for albendazole, respectively Gastrointestinal nematodes demonstrated multiple anthelmintic resistance, as the percentage reduction in egg count was less than 95% and the lower limit of the confidence interval was less than 90%.

Abstract This research aimed to investigate the occurrence of Cryptosporidium and correlate it with types of housing, feces consistency, and physiological parameters related to the reproductive status of Anglo-Nubian goats reared in the State of Piauí, Brazil. A total of 180 fecal samples were collected from 60 non-pregnant and lactating goats with a mean weight of 35 kg, a body condition score of 3.5, and a mean age of three years from an experimental herd at the Federal University of Piauí (UFPI). Oocysts of protozoa of the genus Cryptosporidium could be found in the studied animals using the modified Ziehl-Neelsen technique in fecal smears and the image analysis system to perform morphometry. Each independent variable in the quantitative and qualitative analyses, that is, weight, body condition score (BCS), physiological status (non-pregnant or lactating), feces consistency (normal, pasty, or diarrheal), and floor types (concrete and slatted), was tested with the dependent variable (positive samples, i.e., the presence of Cryptosporidium oocysts). Twenty-four out of the total number of fecal samples were considered positive for the presence of the protozoan, which means that 13.3% of the animals were parasitized. Moreover, 100% of the positive feces samples had normal consistency (firm) and all parasitized animals were reared in pens with a concrete floor. A statistical variation was observed in the BCS of parasitized animals compared to non-parasitized ones (p > 0.0253). The results showed that the occurrence of Cryptosporidium in experimental goats located in the municipality of Teresina, State of Piauí, Brazil, was considered low, requiring sanitary management measures to prevent infection in animals and humans. This is the first report of Cryptosporidium infection in goats in the State of Piauí.

Resumo O objetivo deste estudo foi avaliar e comparar a eficácia de três concentrações de violeta genciana (0,5%, 0,1% e 0,05%) na coloração da cápsula anterior da lente em equinos. Trinta e seis olhos de equinos post-morten foram utilizados. De acordo com a concentração de violeta genciana utilizada, os olhos foram subdivididos em três grupos compostos por 12 olhos cada. A avaliação da eficácia em coloração da cápsula anterior da lente com diferentes concentrações de violeta de genciana foi realizada por meio de um sistema empírico de avaliação da coloração adequada ou inadequada de retalhos capsulares. Com base na avaliação dos examinadores, as concentrações de 0,1% e 0,05% de violeta de genciana permitiram a visualização adequada da cápsula anterior para o treinamento da capsulotomia curvilínea contínua enquanto a concentração de 0,5% produziu uma coloração capsular forte e inadequada. O modelo desenvolvido com violeta genciana, nas concentrações de 0,1% e 0,05%, permitiu a visualização nítida do retalho capsular, o que o torna viável como modelo para treinamento da etapa de capsulotomia curvilínea contínua em cirurgia de catarata em equinos.

Resumo O objetivo deste trabalho foi analisar os efeitos do enriquecimento ambiental alimentar no comportamento dos gambás-de-orelha-preta que se encontravam em cativeiro no Centro de Triagem de Animais Silvestres (CETAS), no município Serra, no estado do Espírito Santo (ES), de agosto a outubro de 2022. Dois modelos alimentares foram construídos para o estudo: os “Tubos Surpresa” e o “Quebra-Cabeça Alimentar”. Foram selecionados 24 gambás-de-orelha-preta, independente do sexo, juvenis, divididos em oito grupos, com três animais cada, sendo quatro grupos expostos a um modelo e quatro ao outro. Cada grupo foi submetido a duas condições: experimental, com a presença do modelo e controle, sem a presença do modelo. Cada condição durou 24 horas e ocorreram em dois dias consecutivos. Foram filmadas com câmera trap, resultando em 3233 vídeos, de 25 segundos cada. Para elaboração do etograma foram selecionados 24 vídeos de cada grupo, gravados entre as 18h00 e 19h30hs, período em que os animais se mostraram mais ativos. Os gambás interagiram com os dois modelos, acessando e comendo os alimentos escondidos, havendo preferência pela carne em comparação com a fruta. Não houve diferença significativa no comportamento dos gambás em relação aos modelos e observou-se que o comportamento agressivo diminuiu significativamente quando os modelos estavam presentes. Conclui-se que os modelos podem ser utilizados como enriquecimento ambiental para os gambás-de-orelha-preta, trazendo benefícios para a diminuição do comportamento agressivo.

Os gambás interagiram com os dois modelos, acessando e comendo os alimentos escondidos, havendo preferência pela carne em comparação com a fruta. Não houve diferença significativa no comportamento dos gambás em relação aos modelos e observou-se que o comportamento agressivo diminuiu significativamente quando os modelos estavam presentes. Conclui-se que os modelos podem ser utilizados como enriquecimento ambiental para os gambás-de-orelha-preta, trazendo benefícios para a diminuição do comportamento agressivo.","PeriodicalId":10310,"journal":{"name":"Ciência Animal Brasileira","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136304845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Resumo Buscou-se com o presente estudo desenvolver um método alternativo de osteotécnica biológica baseado no uso de cascudinhos (Alphitobius diaperinus), um inseto de comportamento necrófago encontrado nos sistemas de produção avícola. Foram utilizados dez cadáveres de animais de pequeno a médio porte e de diferentes espécies, e duas peças ósseas isoladas. Após a retirada dos tecidos moles, os ossos foram acomodados junto aos insetos até a sua limpeza completa. Na sequência, as peças foram avaliadas, clareadas, secas e os esqueletos montados. A utilização dos cascudinhos na preparação biológica de esqueletos demonstrou resultados bastantes promissores, visto que este inseto é de fácil aquisição, manutenção e manipulação, não emite odores desagradáveis ao ambiente, proporciona uma limpeza completa dos esqueletos, atingindo lugares de difícil acesso. Além disso, apresentam grande agilidade na limpeza das carcaças, sendo dispensável a fixação prévia dos tecidos moles para prevenir a putrefação ou o aparecimento de microrganismos, como colônias de fungos.

Abstract In view of the morphological similarity between gastrointestinal stromal tumors (GIST) and other sarcomas of the intestine of dogs, the aim was to carry out the histomorphological and immunohistochemical diagnosis of these tumors, associating breed, sex and age, location and tumor invasion. 217 cases were evaluated by histopathology and 36 diagnosed by immunohistochemistry were included (24 GIST and 12 other intestinal sarcomas). Mixed breed dogs were the most diagnosed with GIST, mainly elderly females (9.5±2.2 years); in the other intestinal sarcomas, crossbreeds and Dachshunds, males and females, were equally affected. The cecum was the most affected by GISTs, with tumor invasion of the intestinal layers in all cases. The small intestine was the most affected by the other intestinal sarcomas, with invasion of the layers in most of these tumors. GISTs expressed markers such as CD117 and DOG-1, unlike other intestinal sarcomas. GIST and other intestinal sarcomas denoted histomorphological and immunophenotypic characteristics similar to histopathology, justifying the association of immunohistochemistry for the definitive diagnosis.
