O escore de condição corporal (ECC) é insuficiente para a determinação da quantidade de gordura corporal em cavalos e para a definição da obesidade. A mensuração da espessura da gordura subcutânea (EGS) por ultrassonografia pode ser considerada um método apropriado para a definição da distribuição de gordura em diferentes locais do corpo em cavalos. Portanto, este estudo teve como objetivo 1) caracterizar a EGS em três diferentes localizações anatômicas (pescoço, região lombar e região glútea), 2) avaliar a relação entre ECC e EGS, 3) determinar a influência de gênero, peso, idade e marcha nas medidas ECC e EGS e, 4) explorar a concordância entre as medidas morfométricas [i.e. índice de massa corporal (IMC), razão da circunferência da cintura:altura da cernelha (CC:AC), razão da circunferência do pescoço:altura da cernelha (CP:AC)], ECC e EGS em uma população de Cavalos Paso colombiano (CPCs). A pontuação da condição corporal de Henneke foi aplicada a 69 CPCs adultas, selecionadas por amostragem de conveniência. Além disso, IMC, CC:AC e CP:AC foram calculados. O percentual de gordura corporal (%GC) foi calculado por meio da ultrassonografia da EGS no pescoço, região lombar e região glútea. A %GC nas CPCs foi de 6,4 ± 1,1. O CC:AC, CP:AC e IMC não foram preditores da %GC ou ECC, e nem o gênero nem a marcha foram decisivos na definição de obesidade nos animais do estudo, embora a idade e o peso fossem variáveis determinantes. De acordo com nossos resultados, o ultrassom é um recurso adequado para calcular a %GC das CPCs. No entanto, deve ser acompanhado pela avaliação do ECC do Henneke. | The body condition score (BCS) is insufficient in determining the amount of body fat in horses, thus defining obesity. Measurement of the subcutaneous fat thickness (SFT) by ultrasonography should be considered as an appropriate method in the definition of fat distribution at different body locations in horses. Therefore, this study aimed to 1) characterize the SFT in three different anatomical locations (i.e. neck, lumbar region, and gluteal region); 2) evaluate the relationship between BCS and SFT; 3) determine the influence of gender, weight, age, and gait on BCS and SFT measurements, and 4) explore the agreement between the morphometric measurements [i.e. body mass index (BMI), girth circumference: height at withers ratio (GC: HW), neck circumference: height at withers ratio (NC: HW)], and BCS and SFT in a population of Colombian Paso Horses (CPHs). The Henneke’s body condition scoring was applied to 69 adult CPHs,selected using a convenience sampling. Additionally, BMI, GC: HW, and NC: HW were calculated. Body fat percentage (BF%) was calculated by ultrasound measurement of the SFT in the neck, lumbar region, and gluteal region. The BF% in the CPHs was 6.4 ± 1.1. The GC: HW, NC: HW, and BMI were not predictors of the BF% or BCS, and neither gender nor gait was decisive in the definition of fattening in the study animals, although age and weight were determining variables. According to our results, ultrasound is an adequate tool to calculate the BF% of the CPHs. However, it must be accompanied by Henneke’s BCS assessment.

Nos últimos anos a relação entre seres humanos e animais de companhia estreitou-se consideravelmente e houve uma expansão da gama de produtos da indústria pet food disponíveis no mercado. Nesse contexto, os petiscos ganharam maior popularidade, uma vez que os tutores buscam agradar seus pets com esse tipo de alimento. Devido à crescente importância do segmento de petiscos, há a necessidade de informações precisas sobre a composição nutricional desses produtos, como o teor de gordura, uma vez que não foram encontrados estudos que avaliassem a eficácia dos métodos de determinação do teor deste nutriente em petiscos destinados a cães e o excesso de minerais pode implicar em riscos para a saúde. Assim, o presente trabalho comparou três metodologias para determinação de gordura em petiscos para cães, e também determinou os seus respectivos teores de umidade, cálcio e fósforo, cujos resultados foram comparados aos valores declarados pelos fabricantes nos rótulos dos produtos. Os métodos de determinação da gordura avaliados foram: extrato etéreo (EE), extrato etéreo após hidrólise ácida (EEHA) e teor de gordura obtido em analisador Ankom XT15 (ANKOM). Vinte e quatro petiscos produzidos por 17 empresas foram avaliados. Os resultados das três metodologias de determinação da gordura foram comparados com o emprego do teste Tukey. A comparação entre os resultados das análises laboratoriais e os valores declarados nos rótulos foi realizada por meio de estatística descritiva. Não houve diferença entre os três métodos avaliados (p = 0,34) em relação ao teor de gordura dos petiscos examinados. Em relação à conformidade nutricional dos rótulos, 25% (n = 6) dos petiscos apresentaram teor de umidade superior ao declarado, 50% (n = 12) apresentaram menor teor de gordura; 25% (n = 6) menor teor de fósforo e, em 50% (n = 12) deles, o teor de cálcio estava fora da faixa mínima e máxima declarada no rótulo. Portanto, devido à ausência de diferença entre os resultados, as três metodologias de determinação de gordura podem ser utilizadas. Quanto à conformidade dos rótulos em relação aos teores de cálcio, fósforo e gordura, é necessário maior controle sobre a composição nutricional desses alimentos, uma vez que a maioria dos tutores fornece petiscos em elevadas quantidades para os cães, que podem determinar excessivo consumo de energia. | In recent years, the relationship between humans and companion animals has tightened considerably and resulted in the expansion of the range of pet food industry products available in the market. In this context, snacks have gained greater popularity as pet owners seek to please their animals by providing such foods. Due to the growing importance of the snack segment, a need exists for accurate information on the nutritional composition of these products, such as fat concentration. No studies were found that evaluated the effectiveness of different methods applied for determining the content of this nutrient in dog snacks. In addition, too much mineral content can pose health risks. Thus, the objective of this study was to compare three methodologies for determining fat in pet snack products. The moisture, calcium and phosphorus content of each was also determined to compare the obtained results with each value stated on their product labels. Fat determination methods evaluated were ether extract (EE), ether extract after acid hydrolysis (EEHA), and fat content obtained from Ankom XT15 analyzer (ANKOM). Twenty-four snacks produced by 17 companies were evaluated. The results of the three methodologies were compared using the Tukey test. The comparison between the results of the laboratory analysis and the values stated on the labels was performed using descriptive statistics. There was no difference between the three methods evaluated (p = 0.34) regarding fat content. Regarding the nutritional compliance of the labels, 25% (n = 6) of the snacks presented higher moisture content than the declared amount, 50% (n = 12) presented lower fat content, 25% (n = 6) lower phosphorus content and, in 50% (n = 12), the calcium content was not within the minimum and maximum range stated on the label. Therefore, due to the absence of difference between the results, any of the three fat determination methodologies could be used. Regarding compliance of labels for calcium, phosphorus and fat content, greater control over the nutritional composition of these foods is required since most pet owners tend to supply large quantities of snacks to dogs, leading to excessive daily energy intake.

A resistência antimicrobiana é uma questão atual e muito importante para a saúde pública, geralmente associada ao uso indiscriminado de antimicrobianos na produção animal. Diante disso, foi investigado o perfil de sensibilidade-antimicrobiana em isolados bacterianos de suínos com sinais clínicos respiratórios no Brasil. Foram estudadas 96 isolados provenientes de 51 granjas de suínos do Brasil. O método de disco-difusão foi empregado usando 14 antimicrobianos: amoxicilina, penicilina, ceftiofur, ciprofloxacina, enrofloxacina, clortetraciclina, doxiciclina, oxitetraciclina, tetraciclina, eritromicina, tilmicosina, florfenicol,lincomicina e sulfadiazina/trimetoprim. Streptococcus suis e Bordetella bronchiseptica foram os patógenos que apresentaram maiores níveis de resistência. Haemophilus parasuis apresentou altos níveis de resistência à sulfadiazina/trimetoprim (9/18=50%). Observou-se que isolados das regiões Centro-Oeste e Sul apresentaram quatro vezes mais chance de serem multirresistentes do que os isolados da região Sudeste. A maioria foi resistente a pelo menos um agente antimicrobiano (98,75%; 158/160) e 31,25% (50/160) das estirpes isoladas eram multirresistentes. No geral, os resultados do presente estudo mostraram grande nívelde resistência à lincomicina, eritromicina, sulfadiazina/trimetoprim e tetraciclina entre patógenos respiratórios bacterianos isolados de suínos no Brasil. Os altos níveis de resistência antimicrobiana em patógenos bacterianos respiratórios em suínos reforçam a necessidade do uso criterioso de antimicrobianos na suinocultura brasileira. | Antimicrobial resistance is a current and important issue to public health, and it is usually associated with the indiscriminate use of antimicrobials in animal production. This study aimed to evaluate the antimicrobial susceptibility profile in bacterial isolates from pigs with clinical respiratory signs in Brazil. One hundred sixty bacterial strains isolated from pigs from 51 pig farms in Brazil were studied. In vitro disk-diffusion method was employed using 14 antimicrobial agents: amoxicillin, penicillin, ceftiofur, ciprofloxacin, enrofloxacin, chlortetracycline, doxycycline, oxytetracycline, tetracycline, erythromycin, tilmicosin, florfenicol, lincomycin, and sulfadiazine/trimethoprim. The majority of isolates were resistant to at least one antimicrobial agent (98.75%; 158/160), while 31.25% (50/160) of the strains were multidrug resistant. Streptococcus suis and Bordetella bronchiseptica were the pathogens that showed higher resistance levels. Haemophilus parasuis showed high resistance levels to sulfadiazine/trimethoprim (9/18=50%). We observed that isolates from the midwestern and southern regions exhibited four times greater chance of being multidrug resistant than the isolates from the southeastern region studied. Overall, the results of the present study showed a great level of resistance to lincomycin, erythromycin, sulfadiazine/trimethoprim, and tetracycline among bacterial respiratory pathogens isolated from pigs in Brazil. The high levels of antimicrobial resistance in swine respiratory bacterial pathogens highlight the need for the proper use of antimicrobials in Brazilian pig farms.

Javalis mantidos em criatórios comerciais utilizam os dentes caninos como mecanismo de defesa e ataque a fim de expressar seus instintos naturais, o que pode resultar em fraturas dentárias e da mandíbula propriamente dita. Desta forma, propiciar a dessensibilização local do nervo alveolar inferior é essencial para a execução de procedimentos terapêuticos na cavidade oral destes animais. Logo, objetivou-se realizar a morfometria do forame mandibular desta espécie a fim de correlacioná-lo com as estruturas mandibulares, inferindo, também, sobre a forma mais segura de realização da referida técnica nos espécimes. Para tanto, foram utilizadas seis hemimandíbulas de Sus scrofa scrofa jovens, a partir das quais foram realizadas as mensurações propostas. Em média, a margem lateral do processo condilar distanciou-se 142,43 mm da raiz do dente incisivo medial inferior; o eixo longitudinal do corpo da mandíbula mediu 22,3 mm ao nível do diastema existente entre o quarto dente pré-molar e o primeiro dente molar inferiores; e o forame mandibular, a partir do extremo caudal de sua margem ventral, posicionou-se a 26,6 mm da margem ventral do ângulo da mandíbula neste nível, 34,92 mm da margem medial do processo condilar, e 38,63 mm do extremo dorsal da margem caudal do processo coronóide. Na falta de diferenças estatisticamente significantes, e observando que o acidente ósseo estudado posicionou-se no ramo da mandíbula, indica que o procedimento proposto deva ser realizado a partir da introdução da agulha em sentido oblíquo rostroventral por 2,0 cm e angulada a 60º com o referencial anatômico criado pela delimitação medial obtida pelo apoio do dedo polegar na margem lateral do ramo da mandíbula, ventralmente ao arco zigomático,preservando as estruturas próximas e definindo-se uma metodologia anestésica inédita para os Javalis. | Boars kept on commercial farms use their canine teeth as a mechanism of defense and attack in order to express their natural instincts, which could result in fractures of the teeth and jaws. Thus, utilizing local desensitization of the inferior alveolar nerve is crucial for executing therapeutic procedures in the oral cavities of those animals. Then, the goal is to carry out the morphometry of the mandibular foramen of that species, correlating it with the mandibular structures, while doing so in the safest manner for the animals. For that purpose, six hemimandibles of young-aged Sus scrofa scrofa were used, from which the proposed measurements were taken. On average, the lateral margin of the condylar process stood 142.43 mm away from the root of the lower medial incisive tooth. The longitudinal axis of the body of the mandible measured 22.3 mm at the level of the diastema that exists between the fourth lower premolar tooth and the first lower molar tooth. The mandibular foramen, from the caudal limit of the ventral margin, would be positioned at26.6 mm from the ventral margin of the angle of the mandible in that level, 34.92 mm away from the medial margin of the condylar process, and 38.63 mm away from the dorsal limit from the caudal margin of the coronoid process. The lack of statistically significant differences, and observing that the osseous accident under scrutiny had been positioned in the ramus of the mandible, indicated that the proposed procedure should be performed from the introduction of the needle in an oblique and rostrodorsal direction for 2.0 cm, and angulated at 60º with the anatomic reference created by the medial demarcation obtained via the support of the thumb on the lateral margin of the ramus of the mandible, ventrally to the zygomatic arch, all while preserving neighboring structures and establishing an unheard-of anesthetic methodology for boars.
