Fifty-six heifers, representing 100% of the category in the herd studied, were evaluated. The heifers were submitted to a gynecological evaluation, prior to hormonal treatment, with ultrasonography, in order to measure the diameter of the uterine horns and ovaries, as well as evaluate the presence of corpus luteum (CL) and antral follicles. According to the values found for the uterine and ovarian diameters, the animals were classified into scores from one to three. After the gynecological evaluation, all animals were submitted to TAI. There was no statistical difference (P&gt;0.05) in pregnancy rates between the different uterine and ovarian scores, as well as in relation to ovarian structures. However, a statistical difference (P&lt;0.05) was observed in the percentage of animals in anestrous within ovarian scores one, two and three (83.3%, 37.5% and 42.8%, respectively). The conclusion was that uterine and ovarian development did not interfere in the pregnancy rate of Girolando heifers in the herd studied.</p> Lara Nogueira Silenciato, Joaquim Esquerdo Ferreira, Samuel Rodrigues Bonamichi do Couto, Otávia Reis e Silva, Osvaldo Almeida Resende, Andressa Ferreira da Silva, Helcimar Barbosa Palhano, Marco Roberto Bourg de Mello Copyright (c) 2020 Lara Nogueira Silenciato, Joaquim Esquerdo Ferreira, Samuel Rodrigues Bonamichi do Couto, Otávia Reis e Silva, Osvaldo Almeida Resende, Andressa Ferreira da Silva, Helcimar Barbosa Palhano, Marco Roberto Bourg de Mello http://creativecommons.org/licenses/by/4.0 http://rbmv.org/index.php/BJVM/article/view/1042 Thu, 23 Jan 2020 00:00:00 -0200 Detomidine and xylazine, at different doses, in donkeys (Equus asinus) http://rbmv.org/index.php/BJVM/article/view/1008 <p>The effects of detomidine and xylazine in northeasters donkeys were compared. Six animals participated, randomly, of all experimental groups: xylazine 10%, 0.8 mg/kg (xylazine group 0.8 - GX0.8), 1.0 mg/kg (GX1.0) and 1, 2 mg/kg (GX1.2); and detomidine 1%, 0.02 mg/kg (Detomidine group 0.02 - GD0.02), 0.04 mg/kg (GD0.04) and 0.06 mg/kg (GD0.06) intravenous. Heart rate (HR) and respiratory rate (RR), rectal temperature (RT), mean arterial pressure (MAP), blood glucose, sedation, analgesia, ataxia, arrhythmias and urination were monitored. Duration of sedation was greater in the groups in which detomidine was administered. The muzzle-soil distance significantly reduced in all groups five minutes after the sedative administration, remaining smaller for a longer time in the GD0.06. Ataxia in GX1.0 was greater than in GX0.08 and GX1,2, being equivalent to GD0,04 and GD0,06. Analgesia lasted 30 minutes in GD0.06 and 10 minutes in the others. There was reduction of HR in GD0.02 and GD0.04 and atrioventricular block. There was a reduction in TR in GX1,2, GD0.02, GD0,04 and GD0,06. RR decreased in all groups. MAP increased in GD0.02, GD0.04 and GD0.06 five, 20, 30 and 10 minutes after administration of detomidine, respectively. Hyperglycaemia occurred for 120 minutes in all animals receiving detomidine. The frequency of micturition was higher in GD0.06 (2.2 ± 0.8) than in GX0.8 (0.8 ± 0.4). In northern Brazil, detomidine and xylazine promote short duration analgesia and cardiorespiratory alterations, but detomidine causes a greater sedative, hypertensive and hypothermic effect.</p> Fernanda Vieira Henrique, Roberta Nunes Parentoni, Arthur Willian de Lima Brasil, Rafaela Alves Dias, Ana Lucélia de Araújo Araújo, Rodrigo de Souza Mendes, Emanuel Ferreira Martins Filho, João Moreira da Costa Neto, Almir Pereira de Souza, Pedro Isidro da Nóbrega Neto Copyright (c) 2020 Fernanda Vieira Henrique, Roberta Nunes Parentoni, Arthur Willian de Lima Brasil, Rafaela Alves Dias, Ana Lucélia de Araújo Araújo, Rodrigo de Souza Mendes, Emanuel Ferreira Martins Filho, João Moreira da Costa Neto, Almir Pereira de Souza, Pedro Isidro da Nóbrega Neto http://creativecommons.org/licenses/by/4.0 http://rbmv.org/index.php/BJVM/article/view/1008 Thu, 23 Jan 2020 00:00:00 -0200 Intestinal and immunological histological parameters of broilers supplemented with commercial probiotic or fungi of the autochthonous microbiota http://rbmv.org/index.php/BJVM/article/view/1012 <p>Objetivou-se avaliar a histomorfometria das porções intestinais de frangos de corte suplementados com probiótico, bem como parâmetros histológicos de órgãos vinculados ao sistema imune. O fungo avaliado <em>Rhizomucor</em> spp. é proveniente de amostras do conteúdo intestinal de frangos Cobb 500. Este foi selecionado <em>in vitro</em> quanto características probióticas e encaminhado para ensaio de desempenho. Foi utilizado um delineamento inteiramente ao acaso com 3 tratamentos e 7 repetições. Uma ave por unidade experimental aos 21 e 42 dias de idade foi sacrificada e, os órgãos foram amostrados, após fixação foram submetidos à desidratação e diafanização e, em seguida, analisados por microscopia óptica e submetidos à análise de histomorfometria e pesquisados pontos que indicavam lesão. Observou-se aos 21 dias que as aves pertencentes ao grupo probiótico formulado a base de <em>Rhizomucor </em>spp. apresentaram maior altura de vilo no duodeno. Também constatou-se um aumento significativo na altura de vilo do jejuno para o grupo controle e probiótico formulado a base de <em>Rhizomucor</em> spp.. Aos 42 dias observou-se, apenas diferença para profundidade de cripta com uso do probiótico comercial para duodeno. Referente as análises das alterações teciduais dos intestinos, baço e bursa aos 21 dias, cem por cento das aves recebendo o fungo <em>Rhizomucor</em> spp. não apresentaram alterações histológicas e aos 42 dias foram observadas alterações na bursa em dois animais. A inclusão do potencial probiótico fúngico <em>Rhizomucor</em> spp. na dieta de frangos de corte aos 21 dias de idade promove maior altura de vilo e aos 42 dias de idade não houve influência.</p> Flávia Oliveira Abrão, Danne Kelle Siqueira Lima, Moisés Sena Pessoa Copyright (c) 2020 Flávia Oliveira Abrão, Danne Kelle Siqueira Lima, Moisés Sena Pessoa http://creativecommons.org/licenses/by/4.0 http://rbmv.org/index.php/BJVM/article/view/1012 Thu, 23 Jan 2020 00:00:00 -0200 Study of the heart rate variability in dogs with brachycephalic syndrome submitted to rhinoplasty surgery http://rbmv.org/index.php/BJVM/article/view/1049 <p>The aim of the present study was to evaluate the HRV in the brachycephalic races, before and after surgical correction of the stenosis of the nostrils, by means of prolonged electrocardiography, observing the excess of the parasympathetic stimulation regarding the occurrence of bradyarrhythmias and their clinical consequences, and possibility of improvement of the autonomic balancing after the treatment, increasing the quality and life expectancy of these patients. Sixteen dogs with nostril stenosis were included, where the analysis and progression of the HRC findings at different moments before the surgical procedure (day 0) and after the procedure were performed in two moments, 30 and 60 days. The technique of alavestibulplasty was performed and HRV analysis was recorded by means of prolonged electrocardiography. For this examination, the indexes were analyzed in the time domain. Regarding the clinical findings, there was an improvement in the evaluation of the heart and respiratory rate, as well as a reduction in parasympathetic activity, as shown in the bradyarrhythmias. Regarding the HRV indexes in the time domain, rMSSD and SDNN associated with mean heart rate findings, have brought strong indications that the reduction of parasympathetic stimulation is related to the reduction of HRV in these animals. The rMSSD is the HRV index in the domain of the time that early changed can be used as indicator of the increase of the parasympathetic activity caused by the Brachycephalic Syndrome</p> Mário dos Santos Filho, Daniel Carvalho Hainfellner, Nathália Marques de Oliveira Lemos, Karen Denise da Silva Macambira Barbosa Macambira, Juliana Silva Do Carmo, Bruno Ricardo Soares Alberigi da Silva Alberigi, Carolina do Valle Aben Athar, Aguinaldo Francisco Mendes Junior, Cristiano Chaves Pessoa da Veiga, Ana Maria Barros Soares, Paulo de Tarso Landgraf Botteon, Julio Israel Fernandes, Jonimar Pereira Paiva Copyright (c) 2019 Mário dos Santos Filho, Daniel Carvalho Hainfellner, Karen Denise da Silva Macambira Barbosa Macambira, Juliana Silva Do Carmo, Nathália Marques de Oliveira Lemos, Bruno Ricardo Soares Alberigi da Silva Alberigi, Cristiano Chaves Pessoa da Veiga, Ana Maria Barros Soares, Paulo de Tarso Landgraf Botteon, Jonimar Pereira Paiva, Julio Israel Fernandes http://creativecommons.org/licenses/by/4.0 http://rbmv.org/index.php/BJVM/article/view/1049 Thu, 23 Jan 2020 00:00:00 -0200 Sucessful of nitempyram in treatment occular myiasis in orbital cavity in dog – case report http://rbmv.org/index.php/BJVM/article/view/1089 <p>The aim of this study was to report the efficacy of nitempiram against Cochiliomiyia hominivorax larvae in ocular myiasis in a naturally infested dog. A female Beagle dog with occular miyasis was attended. After care and clinical examination, was found involvement of the entire ocular and periocular region. The animal was treated with nitenpyram, with a dose of 4,7 mg/kg, orally, jointly with analgesic medication. The expulsion and fall of live and dead larvae were evaluated, which were quantified every 15 minutes in the first hour and thereafter at 2, 3, 4, 6, 18 hours after treatment and subsequent manual removal of the larvae. Overall effectiveness was calculated, the larval expulsion rate and the larvicidal effect of nitenpyram. In full there were 140 larvae in the lesion, from which 90 live larvae were expelled, 46 dead larvae and 4 dead larvae mechanically removed, presenting 100% overall effectiveness, with larval expulsion activity of 97.1% and larvicidal efficacy of 35.7%. Based on the results obtained in this case, it can be concluded that nitenpyram has a fast-acting and safe action under <em>C. hominivorax </em>larvae, proving be a pleasant alternative therapeutic alternative for the elimination of myiasis in orbital cavity of dogs.</p> Fernando Rocha Miranda, Renan Bernardes Tavares, Ciro Eugênio da Silva de Oliveira, Emily Andressa Santos Lima , Diefrey Ribeiro Campos, Fabio Barbour Scott, Julio Israel Fernandes Copyright (c) 2020 Fernando Rocha Miranda, Renan Bernardes Tavares, Ciro Eugênio da Silva de Oliveira, Emily Andressa Santos Lima , Diefrey Ribeiro Campos, Fabio Barbour Scott, Julio Israel Fernandes http://creativecommons.org/licenses/by/4.0 http://rbmv.org/index.php/BJVM/article/view/1089 Thu, 13 Feb 2020 00:00:00 -0200
