Avaliações ultrassonográfica e radiográfica dos efeitos da suplementação com dois tipos de probióticos sobre o intestino de cães filhotes

Abstract

RESUMOAvaliaram-se os efeitos da suplementação de dois tipos de probióticos para cães filhotes da raça Beagle, que receberam dois tipos de dieta de alta e baixa qualidade, sobre os achados em exames de diagnóstico por imagem. Foram utilizados 18 cães filhotes da raça Beagle, distribuídos em três tratamentos inteiramente ao acaso: tratamento 1, controle (ração); tratamento 2, ração com probiótico 1 (Bifidobacterium); e tratamento 3, ração com probiótico 2 (Lactobacillus). O experimento foi dividido em duas fases, cada uma caracterizada pela mudança da dieta de qualidades diferentes. Ao exame ultrassonográfico, foi avaliada a espessura da parede gastrintestinal, e ao radiográfico, a presença de gás em alças intestinais e o espessamento da parede. Observou-se aumento da espessura da parede das alças intestinais (P<0,05), nos animais dos grupos tratados com probiótico 1 e 2 (5,74mm e 6,01mm, respectivamente) em relação aos do grupo-controle (5,03mm). O uso de probióticos não influenciou a produção de gás intestinal. Não houve diferença (P>0,05) entre os tratamentos quanto ao escore de gás intestinal. A avaliação quantitativa permitiu a determinação de um escore de gás intestinal, de forma não invasiva, por meio do software Image J ® . Concluiu-se que o diagnóstico por imagem sustenta a recomendação dessa metodologia como ferramenta auxiliar na avaliação nutricional de dietas para cães.Palavras-chave: cão, ultrassonografia, radiografia, probióticos (P <0.05) in animals treated with probiotic, groups 1 and 2, ((5,74mm and 6,01mm, respectively) ABSTRACT The effects of supplementation with types of probiotics for beagle puppies that received high and low quality diets on the findings of imaging techniques were evaluaded. Eighteen animals were distributed in three randomized treatments: 1, control (diet), 2, diet with a probiotic (Bifidobacterium), and 3, diet with another probiotic (Lactobacillus). The experiment was divided into two phases each characterized by a change of diet. By ultrasonography, the thickness of the gastrointestinal wall was evaluated as well the presence of gas in the bowel and thickening of the wall by radiography. There was an increase in the thickness of the intestinal wall

Inclusion of Yucca schidigera extract in diets with different protein levels for dogs

“…Although the program and the method used to measure the intestinal gas field are recent, there is still a need for improvement to match the pictures taken and the mechanism for measuring the gas area. The methodology used in this study has been a very effective tool in determining the area of intestinal gas noninvasively in some animal studies (Feliciano et al ; Félix et al ).…”

“…Analyses were based on the area of gas in bowel loops, by contrast threshold. The contrast thresholds were adjusted for each image, which contained a reference to size by the scale of 1.0 cm (Feliciano et al ).…”

“…The thickness of the intestinal wall was determined by the measurement between the outside echogenic serosal surface and the interface mucosa/lumen. This test was done with ultrasonographic equipment (model SSH‐140; Toshiba, Tustin, CA, USA) using a 5 MHz transducer (Feliciano et al ).…”

“…Analyses were based on the area of gas in bowel loops, by contrast threshold. The contrast thresholds were adjusted for each image, which contained a reference to size by the scale of 1.0 cm (Feliciano et al 2010). For ultrasonographic evaluation, there were three measurements of the intestinal wall for each animal, always in the proximal duodenum.…”

“…Each animal was imaged in two positions: left lateral-lateral and ventrodorsally. Then, images were photographed, digitized and evaluated using the software Image J ® as described by FELICIANO et al (2010).…”
