A escassez de cães doadores de sangue em situações de emergência na Medicina Veterinária pode levar a realização de transfusões de sangue entre animais que não tiveram seu tipo sanguíneo previamente determinado. O padrão de anticorpos serve como um sinal de alerta para animais que serão submetidos a uma segunda transfusão sanguínea, sendo essa somente recomendável a partir de cães doadores compatíveis. Este artigo aborda a pesquisa de anticorpos anti-AEC 1 pela técnica de citometria de fluxo em cães que receberam uma transfusão utilizando sangue do grupo AEC 1 positivo, comparando os resultados com aqueles obtidos a partir de reação cruzada. Foi utilizado sangue de 18 animais doadores do tipo AEC 1 positivo classificados por técnica cromatográfica para transfundir trinta e três animais com tipos sanguíneos desconhecidos, os quais mostraram reação cruzada negativa aos doadores. Nos dias 7, 14, 21 e 28 pós-transfusão, 45% e 27% dos animais mostraram-se positivos para os anticorpos anti-AEC 1, respectivamente, pela reação cruzada e através de citometria de fluxo. A pesquisa de anticorpos com o emprego da técnica de citometria de fluxo tem alta especificidade e sensibilidade, enquanto a reação cruzada, altamente sensível, tem baixa especificidade. Animais que não apresentaram positividade após a transfusão de sangue na reação cruzada e na citometria de fluxo concomitantemente foram considerados de qualquer outro grupo sanguíneo diferente do grupo sanguíneo AEC 1 positivo. | The shortage of dog blood donors in veterinary emergencies can lead to blood transfusions between animals whose blood type has not been identified. The antibody profile serves as a warning sign for animals that require a second blood transfusion, which is only advisable from compatible donor dogs. This article focuses on determination of anti-DEA 1 antibodies using the flow cytometry technique in dogs that have undergone a transfusion using DEA 1-positive blood, compared to results obtained from crossmatching. Blood from 18 DEA 1-positive donors ranked according to the chromatographic technique was used to transfuse thirty-three animals with unknown blood types and which demonstrated negative crossmatching to donors. On post-transfusion days 7, 14, 21 and 28, 45% and 27% of the animals tested positive for the anti-DEA 1 antibody, through crossmatching and flow cytometry, respectively. Detecting antibodies using the flow cytometric technique has high specificity and sensitivity, while crossmatching methods are highly sensitive but manifest low specificity. Following blood transfusion, animals that did not present as positive through crossmatching or flow cytometry were considered different from all other DEA 1-positive blood groups.

Os conflitos Humanos-Animais Selvagens são uma realidade crescente e triste no mundo inteiro, tornando o controle populacional da fauna silvestre e animais ferais o maior desafio, principalmente diante do crescimento da população humana e, consequentemente, da diminuição dos habitats naturais dos animais. As atividades humanas e a destruição da natureza, forçam os animais de vida livre a se dirigirem para áreas urbanas e agrícolas, inevitavelmente, causando conflitos, como o risco de zoonoses, acidentes de trânsito, bem como danos às plantações, quando em busca de alimentos, cujo prejuízo chega a milhões de dólares. Durante décadas, a ciência esteve empenhada em esforços extensivos para desenvolver métodos de controle populacional “humano”; e muitas técnicas foram utilizadas, a fim de se realizar um controle populacional destes animais silvestres. Neste artigo será apresentada uma visão geral dos métodos anticoncepcionais aplicados, com demonstrações gráficas simplificadas de suas interações com a fisiologia reprodutiva, bem como relacionando os prós e os contras dos agentes antifertilidade empregados; também serão comparados com um conjunto de características desejadas para as aplicações em fauna a campo, com ênfase em imunocontracepção reversível, concluindo assim, com as razões do porque este conceito torna-se o mais apropriado e promissor para animais silvestres de vida livre. | Human-wildlife conflicts, a growing and sad reality worldwide, makes population control of wildlife and feral animals one of the biggest challenges in wildlife management, especially due to the rapidly expanding human population, and consequently the ever-diminishing natural habitats of animals. Human activities and the destruction of nature forcing wildlife to move inevitably into urban and agricultural areas, causing “conflicts”, such as the risk of zoonosis and traffic accidents, as well as damage to crops in the search for food, whose losses reach millions of dollars. For decades, science has been engaged in extensive efforts to develop methods of “humane” population control methods, and many techniques are being employed in order to control wildlife population. In this article, we present an overview of applied contraceptive methods with simplified graphic demonstrations of their interactions with reproductive physiology, furthermore relating pro and contra of utilized antifertility agents. These are being compared to a set of desired characteristics for free-ranging wildlife for in-field applications, with emphasis on reversible immunocontraception – concluding, therefore, the reasons why this concept is becoming the most appropriate and promising for free-ranging wildlife.

O presente trabalho analisou o emprego do leite em pó desnatado (LPD) adicionado de frutose em uma nova curva de resfriamento para criopreservação de sêmen suíno. Um total de 49 ejaculados, de sete varrões foram criopreservados utilizando a nova curva de resfriamento com glicose e frutose adicionada aos diluentes Beltsville Thawing Solution (BTS + D; BTS + F) e Leite em pó desnatado (LPD + D; LPD + F), totalizando quatro grupos experimentais para análises. Ao final da curva, as alíquotas de sêmen foram envasadas em palhetas de 0,5 mL e mantidas em nitrogênio líquido. Durante a curva de resfriamento, a média de vigor e motilidade espermática do LPD foi maior do que do BTS (p < 0.05). Após descongelação, observou-se queda do vigor e motilidade em ambos diluentes, com o BTS apresentando melhores resultados de vigor (2,1 ± 0,55) e de motilidade (38 ± 21,8) (p < 0,05). Entretanto, o uso da frutose permitiu equiparação dos valores da motilidade entre LPD e BTS (p > 0,05). A funcionalidade de membrana foi melhor preservada com adição da frutose, em ambos os diluentes. Os dados de vitalidade espermática foram significativamente maiores no diluente contendo glicose e LPD (71,8 ± 12,5). A porcentagem de acrossomas intactos foi maior no tratamento que continha glicose, independentemente do diluente utilizado (BTS + G: 81,8 ± 7,2, SMP + G: 81,4 ± 14,2). Os resultados obtidos indicaram que o BTS, ainda é a melhor opção de criopreservação e que a frutose pode ser utilizada para criopreservação de sêmen de varrão na nova curva de resfriamento. | This study aimed to analyze skimmed milk powder (SMP) and fructose in a new cooling curve to freeze boar semen. A total of 49 semen samples from seven boars were cryopreserved using the new curve with addition of glucose and fructose to the refrigerating diluents: Beltsville Thawing Solution (BTS + G; BTS + F) and Skimmed milk powder (SMP + G; SMP + F), totaling four experimental groups for analysis. To finish the curve, aliquots of semen were packaged in 0.5 ml straws and kept in liquid nitrogen. During the cooling curve, SMP mean spermatic vigor and motility were greater than the BTS (p < 0.05). After thawing, a decrease of spermatic force and motility in both extenders was observed, where the BTS presented spermatic vigor (2.1 ± 0.55) and motility (38 ± 21.8), presenting better results (p < 0.05). There was no statistical difference between sugars added to the BTS and SMP in spermatic force and motility (p > 0.05), although the use of fructose allowed an equalization of motility between the SMP and BTS (p > 0.05). Functionality of membrane was better preserved with the addition of fructose, in both extenders. The rate of sperm viability was significantly higher in extender containing glucose and SMP (71.8 ± 12.5). The percentage of intact acrosome was higher on the treatment containing glucose, independent of the extender (BTS + G: 81.8 ± 7.2, SMP + G: 81.4 ± 14.2). To conclude, the results suggest that the BTS is still the best option to cryopreserve and fructose could be used in boar semen cryopreservation in new cooling curve.

Os efeitos de diferentes taxas de semeadura e altura de corte na produção e composição bromatológica do milheto foram avaliados em dois experimentos executados em delineamento em blocos casualizados. No primeiro experimento, foram utilizadas 32 parcelas (1,2 x 1,2 m) e avaliadas as taxas de semeadura de 24, 35, 50 e 60 kg/ha. Três cortes foram realizados para avaliar a altura das plantas, a produção de massa fresca e seca, os teores de matéria seca (MS), fibra em detergente neutro (FDN), proteína bruta (PB) e lignina, assim como a digestibilidade in situ da matéria seca e FDN. No segundo experimento, 20 parcelas (1,2 x 3,0 m) foram usadas para avaliar o efeito das alturas de corte de 20, 30, 40 e 50 cm, sobre as variáveis previamente citadas. De acordo com o aumento da taxa de semeadura, houve aumento linear da altura das plantas e da produção de massa seca e fresca e tendência de redução linear da digestibilidade in situ da matéria seca, sem afetar a composição da forragem. A altura de corte não afetou a concentração de proteína bruta, mas aumentou linearmente a altura das plantas, a produção de massa seca e o teor de matéria seca e tendeu a reduzir a digestibilidade in situ da FDN e a concentração de lignina. Assim, o emprego de maiores taxas de semeadura (60 kg/ha) e de altura de corte (50 cm) aumentam a produção de forragem, enquanto que menores alturas de corte aumentam a qualidade da forragem. | This study evaluated the effect of different seeding rates and cutting heights on production and composition of millet. Two randomized block design experiments were performed. In the first trial, 32 parcels (1.2 × 1.2 m) were used for evaluation of seeding rate of 24, 35, 50 and 60 kg/ha. Three cuts were carried out to evaluate plant height, fresh and dry mass yield, dry matter (DM), neutral detergent fiber (NDF), crude protein (CP) and acid detergent lignin (ADL) concentration and in situ DM and NDF digestibility. In the second trial, 20 parcels (1.2 × 3.0 m) were used to evaluate 20, 30, 40 and 50 cm of cutting heights for two growing cycles, performing the evaluations previously listed. Seeding rate linearly increased plant height, fresh and dry mass production, and tended to linearly decrease dry matter in situ digestibility, without effects on forage composition. Cutting height had no effect on crude protein (CP) concentration, but linearly increased plant height, dry mass production, DM content and tended to decrease NDF in situ digestibility and ADL content. Thus, the use of the highest evaluated seeding rates (60 kg/ha) and cutting height (50 cm) increased forage production; however, the use of the lowest residual height increased forage quality.

Quando fraturas ósseas ocorrem, forças externas produzem movimentação interfragmentária continuamente e um método de estabilização se faz necessário. É sabido que as condições mecânicas no local de fratura influenciam a formação de calo durante o processo de cicatrização óssea e para que cicatrização óssea primária seja obtida é necessária estabilidade absoluta no foco de fratura. O conceito de strain de Perren determina que a deformação relativa no foco de fratura estabilizado depende do tamanho da lacuna de fratura original. Fraturas redutíveis (sem cominuição) são consideradas de alto strain, pois uma pequena força aplicada a linha de fratura resulta em grande movimentação com efeito deletério ao processo de consolidação. O presente trabalho revisa a literatura disponível a respeito de fatores que influenciam a mecânica de fraturas de alto strain em medicina veterinária, seus métodos de tratamento e a física por trás dos implantes disponíveis. Cada configuração de fratura requer atenção especial e cuidado crítico na escolha do método de osteossíntese e no tipo de estabilidade necessária para que a consolidação ocorra no tempo esperado. Conhecimento da teoria do strain é mandatório para a formação de cirurgiões ortopédicos. | Whenever bone fractures occur, external forces produce continuous interfragmentary motion and a stabilization method is necessary. It is known that the mechanical conditions at the fracture site influence bone callus formation during healing process. To achieve primary (direct) bone healing, absolute stability at the fracture site is necessary. Perren’s concept of strain determines that relative deformation at the fracture gap depends on the original gap’s conformation. Simple fractures (without comminution) are considered high strain fractures since a small force applied to the fracture site results in great movement with deleterious effects on the healing process. The purpose of this study is to review the available literature regarding factors that influence the mechanics of high strain fractures in veterinary medicine, its treatment methods and implants available. Each fracture configuration requires special attention and critical care in choosing the osteosynthesis method and the type of stability required for consolidation to occur within the expected time. One must know the strain theory to become an orthopedic surgeon.

Este trabalho avaliou o efeito da contagem de células somáticas (CCS) na composição e na qualidade higiênica do leite de tanque de rebanhos leiteiros. Especificamente, foram avaliados o efeito da CCS do tanque de rebanhos leiteiros na composição (gordura, proteína, sólidos totais, extrato seco desengordurado) e nas contagens bacteriana total (CBT), de psicrotróficos (CP) e de coliformes (CC). Um total de 230 rebanhos leiteiros localizados no sul de Minas Gerais e oeste de São Paulo foram selecionados com base na média geométrica da CCS obtida de cinco análises mensais anteriores ao início das coletas das amostras. As fazendas foram classificadas de acordo com a CCS em três grupos: baixa (&lt; 250.000 células/mL, n = 84), média (&gt; 250.000 e &lt; 750.000 células/mL, n = 79) e alta CCS (&gt; 750.000 células/mL, n = 67). Após a seleção dos rebanhos, amostras de leite do tanque foram coletadas a cada catorze dias durante três meses, totalizando 1.380 amostras, as quais foram submetidas às análises de composição, CBT, CP e CC. Uma redução da CBT e da CC foi observada em rebanho com baixa CCS; entretanto, rebanhos com média e alta CCS tiveram aumento nos teores de gordura, proteína bruta e sólidos totais. Uma média correlação foi observada entre CBT e CP (r = 0,6215) e também entre CP e CC (r = 0,3692). Com base nos indicadores de higiene e na composição do leite, foi observada uma correlação baixa e negativa entre CBT e gordura (r = -0,0585), CP e gordura (r = -0,0585) e CP e sólidos totais (r = -0,0662). Os rebanhos leiteiros com CCS &lt; 250.000 células/mL apresentaram maior qualidade higiênica do leite de tanque; entretanto, considerando a composição, rebanhos com maior CCS tiveram maiores concentrações de gordura e proteína. | This study evaluated the effect of somatic cell count (SCC) on composition and hygienic quality of dairy herd bulk tank milk – specifically, the effect of SCC of bulk tank of dairy herds on composition (fat, protein, total solids, nonfat dry solids) and on total bacterial count (TBC), psychrotrophic count (PC) and coliform count (CC) were evaluated. A total of 230 dairy herds located south of Minas Gerais and west of São Paulo were selected based on SCC geometric mean obtained from five monthly analyses preceding the start of the sampling. The dairy farms were classified according to SCC in three groups: low (&lt; 250,000 cells/mL, n = 84), medium (&gt; 250,000 and &lt; 750,000 cells/mL, n = 79) and highSCC (&gt; 750,000 cells/mL, n = 67). After herd selection, bulk tank milk samples were collected every 14 days for three months totaling 1380 samples, which were subjected to analysis of composition, TBC, PC, and CC. A decrease of TBC and CC was observed in herds with low SCC; however, herds with medium and high SCC had an increase in fat, crude protein, and total solids contents. A medium correlation was observed between TBC and PC (r = 0.6215), and also between PC and CC (r = 0.3692). Based on hygiene indicators and milk composition, a low and negative correlation between TBC and fat (r = -0.0585), PC and fat (r = -0.0585), and PC and total solids (r = -0.0662) was observed. Dairy herds with SCC &lt; 250,000 cells/mL had higher bulk tank milk hygienic quality; however, considering the composition, herds with higher SCC produced higher milk fat and protein concentration.

O presente estudo avaliou a suplementação dietária com óleo essencial de Lippia alba sobre os parâmetros hemato-imunológicos em tilápias do Nilo (Oreochromis niloticus) submetidas à inflamação aguda induzida por carragenina na bexiga natatória. Pelo período de 45 dias, 96 peixes foram divididos em quarto tratamentos em triplicata: a) peixes suplementados com óleo esencial de L. alba (4 mL kg-1 de ração) injetados com carragenina; b) peixes suplementados com álcool de cereais injetados com carragenina; peixes não suplementados com óleo essencial injetados com carragenina; c) peixes não suplementados não injetados. Os níveis de cortisol, eritrograma, leucograma e o infiltrado inflamatório foram analisados seis horas após o estímulo inflamatório. Peixes injetados com carragenina apresentaram reação inflamatória aguda na bexiga natatória caracterizada por maior infiltrado de neutrófilos e monócitos. O número de neutrófilos circulantes foi significativamente maior nos peixes suplementados com L. alba quando comparado aos outros tratamentos. Não houve diferença nos níveis de cortisol. Para a dose, o tempo e a forma de administração testada, a suplementação com óleo essencil de L. alba não apresentou atividade anti-inflamatória. Por outro lado, foi constatada influência da suplementação dietária no número de neutrófilos após a aerocistite enfatizando a sua característica imunomoduladora. | The present study evaluated the dietary supplementation with essential oil of Lippia alba on the hemato-immunological parameters of Nile tilapia (Oreochromis niloticus) submitted to acute inflammation induced by carrageenin injection in the swim bladder. For a period of 45 days, 96 fish were divided in four treatments in triplicate, as follows: fish fed supplemented diet with essential oil of L. alba (4 mL kg-1 dry ration) injected with carrageenin; fish fed supplemented diet with cereal alcohol injected with carrageenin; fish fed unsupplemented diet with essential oil injected with carrageenin; fish fed unsupplemented diet and noninjected. Cortisol levels, erythrogram, leukogram and the inflammatory infiltrate were analyzed 6 h after inflammatory stimulus. Carrageenin-injected fish showed acute inflammatory reaction in the swim bladder characterized by higher infiltrate of neutrophils and monocytes. The circulating neutrophils number was significantly higher in fish fed L. alba when compared to other treatments. No difference in cortisol levels was found. For dose, time and administration form tested, supplementation with essential oil of L. alba did not present anti-inflammatory activity. On the other hand, influence of dietary supplementation was observed on the neutrophils number after induced aerocystitis highlighting its immunomodulatory characteristic.

peer reviewed | Objective: The aim of the study was to assess the weight and reproductive performances of Girolando cattle at Kpinnou Breeding Farm (KBF) in the south western of Benin Republic. Materials and methods: The weight performance and body measurements were taken on a total of 150 Girolando cattle. The study of the reproductive traits was based on the recorded demographic indicators between 2012-2013 of 67 cows. Results: From calving to the age of 3 months, the monthly average weight of calves did not vary with the season of calving (P>0.05). Between the 4th and 9th month, the weight varied with the birth seasons and the sex of the calf. Beyond 9th month, the calf’s average weight was the same regardless the calving season. At the age of 24 months, the highest weight (393.33 kg) was obtained during the long rainy season. The highest average weight was 398.22 Kg for males against 364.25 Kg for females at 24 months. The fertility rates ranged from 91.18% to 100% and the fecundity rate ranged from 85.29% to 103% during the study period. The apparent fertility rate was 91.18%. As for the calving and abortion rates, they were 93.55% and 6.45%, respectively. The mortality rate before weaning was 6.90% while the weaning viability was 93.10%. Calving occurred from January to June and from August to December. Conclusion: In overall, the Girolando performances are satisfactory and show a good adaptation at KBF.
