Knowledge of the distribution of agents causing parasitic diseases is important so that we can intervene in breeders, therefore, the objective of the present work is to report the occurrence of infection by Eustrongylides spp. (Nematoda: Eustrongylidae) in Polypterus endlicherii (Polypteriformes: Polypteridae) in central Rio Grande do Sul, Brazil. The nematode was identified after being released a cyst in the scales, of a fish of the species P. endlicherii. It can be concluded that this is the first record of the occurrence of Eustrongylides spp. larvae in fish in Rio Grande do Sul, showing that the parasite is present in the central region of the state. Therefore, further studies should be carried out in order to verify the presence of the parasites in fish intended for human consumption. It should also be noted the need to be more careful when feeding fish with oligochaetes, especially those intended for human consumption.","PeriodicalId":38520,"journal":{"name":"Ciencia Animal Brasileira","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67270721","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}

Decree No. 9,013, which revokes Decree No. 30,691 of 1952, was published on March 29, 2017, and major changes occurred in the legislation described in RIISPOA, such as the criteria for judging carcasses. This study aimed to verify whether these changes had an impact on the condemnations of bovine carcasses due to tuberculosis and cysticercosis in the State of Rio Grande do Sul, RS, Brazil. The number of slaughtered animals and the number of carcasses condemned due to tuberculosis and cysticercosis from 2014 to 2020 were obtained from the Agricultural Defense System (SDA) database, the official data system of the Secretariat of Agriculture, Livestock, and Rural Development (SEAPDR). An increase in the number of cases of carcasses condemned due to cysticercosis and a reduction of animals affected by the disease were observed in the period after changes in the regulation. The number of carcasses condemned due to tuberculosis and the number of animals affected by the disease remained stable after changes in the regulation. The results showed that changes in federal legislation had a real impact on the historical series of condemnations of bovine carcasses due to cysticercosis in the State of Rio Grande do Sul, while the impact of condemnations on carcasses affected by tuberculosis was not significant.","PeriodicalId":38520,"journal":{"name":"Ciencia Animal Brasileira","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67270343","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}

Environmental variables were analyzed, and the following heat stress indices calculated: black globe-humidity index (BGHI) and equivalent temperature. The average BGHI and equivalent temperature were 79 and 26, respectively. Walking behavior differed between treatments (P<0.05) and was more frequent in the woven geotextile treatment. The most frequent behavior observed throughout the day was lying in the shade (53%), demonstrating the importance of providing artificial shading during this stage of life. When compared to polyethylene mesh, the drainage geocomposite and nonwoven geotextile were better suited to providing shade for dairy calves undergoing weaning in tropical regions.","PeriodicalId":38520,"journal":{"name":"Ciencia Animal Brasileira","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67269999","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}

This study investigated the correlation between age, degree of ossification of the distal radial epiphysis, sex, and career longevity of Thoroughbred racehorses in Brazil from 2012 to 2015. We performed a retrospective evaluation of 286 dorsopalmar radiographs of the left radiocarpal region of young horses and their racing performance. Distal radial epiphyseal closure was classified into three degrees: A, B, or C. Performance data included the number of races raced, athletic career length, and the number of races per month. The variables were subjected to regression analysis. At the time of radiographic examination, male horses were significantly older than females, and horses with epiphyseal closure degrees differed with age. Age at first race was 33.08±3.81 months, the average of races raced was 18.32±15.14 races, athletic career duration was 20.37±13.82 months, and the number of races raced per month was 0.93±0.46 races. Age influenced (P>0.001) the distal radial epiphyseal closure on racehorses, but sex did not (P=0.218 for males and P=0.275 for females). An inverse association was observed between age at the first race, the number of races raced per month, and athletic career duration. The frequency of race and the age at the first race influenced athletic career duration.","PeriodicalId":38520,"journal":{"name":"Ciencia Animal Brasileira","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67270641","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}

Many adaptations arose, including in locomotor patterns and behaviours, and the nervous system adapted to those new habits. We have described the macroscopic anatomy and cytoarchitecture of the Amazon Lava Lizard brain (Tropidurus torquatus), an abundant lizard in South America. Fifteen specimens were captured, euthanized and their brains were dissected, eight of these were processed and stained in haematoxylin-eosin. Their main areas of the brain are the telencephalon and diencephalon, in the forebrain, tectum and tegmentum, in the midbrain and medulla oblongata and cerebellum, in the hindbrain. The main and accessory olfactory bulbs are the most rostral structure of the brain and are composed of six layers. Brain hemispheres compose the telencephalon and are divided in pallium and subpallium. Medial, dorsomedial, lateral and dorsal cortices are part of the pallium. Striatum, pallidum and septum compose the subpallium. The diencephalon is composed of thalamus, epithalamus and hypothalamus. The midbrain has a ventral tegmentum, composed of torus semicircularis and a dorsal 14 layered optic tectum. Most part of the hindbrain is composed of the medulla oblongata, and the cerebellum arises from it, forming a three-layered plate like structure. In general, the brain of Tropidurus torquatus resembles those of other lizards, with its own adaptations.","PeriodicalId":38520,"journal":{"name":"Ciencia Animal Brasileira","volume":"51 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67270392","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}

Diseases emerge in nature and infect living beings current on all continents, even in the current scenario of biomedical research evolution. Among the most studied emerging animal diseases are the swine viral diseases, due to their high occurrence and severity. Added to this, is the economic impact on the health of pigs and in some cases on human health. The challenges of swine health include endemic diseases, foodborne and transboundary diseases. Idiopathic vesicular diseases and subclinical diseases have also been identified, either alone or in combination with other infections. Several factors have contributed to these phenomena, but failures in biosecurity, biocontainment, and herd immunity imbalances are critical and must be addressed. Viruses evolve naturally, through mutation, rearrangement, or recombination, either to become more virulent or more transmissible, or not. This review will discuss the broad field of emerging swine viral infections, how monitoring the evolution of these viral agents is of supreme importance. Also, when should a new disease or emerging agent is considered a risk to swine production? Although the evolution of pork production systems is admirable, animal diseases continue to account for 20% of the losses. Therefore, international organizations work with member countries to prevent animal diseases, ensure food supply, maintain household income, health, and preserve the future.
