Características histomorfométricas do intestino de juvenis de tambaqui após uso de probiótico na dieta e durante transporte

Abstract: Avaliou-se neste trabalho as características histomorfométricas da mucosa intestinal de tambaqui após uso de probiótico a base de Bacillus spp., veiculado na ração e dissolvido na água durante transporte. Foi utilizado um delineamento inteiramente casualizado com três tratamentos e sete repetições, sendo comparado um tratamento controle (peixes alimentados com ração comercial sem probiótico) a dois outros tratamentos envolvendo o uso de probiótico comercial, veiculado na ração ou na água de transporte. Um tota… Show more

“…According to Ferreira et al (2014), the integrity of the gut mucosa can be evaluated from morphological measurements of gut fold, in order to determine an animal's gut digestive and absorptive capacity. However, in poultry, chicken, betaine supplementation was beneficial for the gut epithelium (Kettunen et al, 2001), considering its capacity of acting as an osmolyte, maintaining the integrity and structure of villi and promoting an improved digestibility and absorption of nutrients (Niang, 2005).…”

“…Thus, the intestinal mucosa maximizes the digestive process and represents an extensive area of digestion and absorption of nutrients (MACARI;MAIORKA, 2000), the height of the villi being directly proportional to the absorption area. The integrity of the intestinal mucosa can be assessed from measurements of villus height, according to Ferreira et al (2014), since the balance between cell renewal and cell loss that normally occurs in the intestine determines a constant cell renewal, maintaining the size of the villi and consequently the digestive capacity and intestinal absorption. Honorato et al (2011), describe that the height of the intestinal villi of tilapia was influenced mainly by the diet containing fish silage as a source of protein of animal origin.…”

“…Research has also been carried out with probiotics for aquatic animals, evaluating the positive effects on the intestinal morphology of animals, such as benefits on the microvilli structure and absorptive surface (CARVALHO et al 2011;MELLO et al 2013;FERREIRA et al, 2014).…”

“…Os probióticos são microrganismos vivos que atuam sobre a microbiota intestinal, e podem ser incorporados a dieta na forma de aditivos ou acrescentado a água de manutenção (Nawaz et al, 2018). Embora bactérias do gênero Bacillus sejam estudadas para peixes, as respostas obtidas para tambaqui com estas bactérias desenvolvidas sem associação natural ao hospedeiro não foram positivas para desempenho e resistência imunológica (Ferreira et al, 2014;Azevedo et al, 2016;Paixão et al, 2017). No entanto, Dias et al (2018) utilizaram bactérias autóctones (Bacillus cereus) isoladas do intestino do tambaqui e observaram melhores respostas hematológicas, fisiológicas e produtivos.…”
