“…Acetate is the most abundant SCFA and is an essential cofactor/metabolite for the growth of many beneficial bacteria, while butyrate is considered one of the most important fermentative metabolites for gut health, being the main energy source for colonocytes and reducing gut inflammation (Chen & Vitetta, 2018; Zhong et al, 2019). The increase in the faecal concentration of butyrate was also reported in other studies evaluating the dietary supplementation of orange (Volpe et al, 2021) and apple (de Brito et al, 2021) fibres for dogs.…”

“…Studies evaluating single sources and blends of dietary fibres in dog foods also showed that the SF fraction presents greater apparent digestibility than the IF fraction (Sabchuk et al, 2017; Souza et al, 2021; Sunvold et al, 1995). The SF fraction usually presents greater availability as a substrate for intestinal fermentation than IF, resulting in its disappearance from the gastrointestinal tract (Volpe et al, 2021), which is calculated as its CTTAD.…”

“…The SF fraction is an important substrate for gut microbiota fermentation, contributing to the maintenance of eubiosis and resulting in the production of functional metabolites, such as short‐chain fatty acids (SCFA). The SCFA are an important energy source for colonocytes (especially butyrate), regulate epithelial barrier integrity and water and electrolytes absorption, support the immune system and modulate inflammatory responses (de Brito et al, 2021; Panasevich et al, 2013; Volpe et al, 2021). On the other hand, the IF fraction stimulates peristalsis and can alter faecal consistency (Kröger et al, 2017; Sabchuk et al, 2017).…”

“…Although studies already have demonstrated the physiological effects of fibre sources, such as beet pulp, cellulose, soy hulls and fruit pomaces on the gastrointestinal functionality of dogs (de Brito et al, 2021; Donadelli & Aldrich, 2019; Donadelli et al, 2021; Pacheco et al, 2021; Panasevich et al, 2015; Sabchuk et al, 2017; Souza et al, 2021; Volpe et al, 2021), only one study (Souza et al, 2021) evaluated the effects of CA in this species. The study of Souza et al (2021) demonstrated that CA is fermentable in the gut, altering the production of fermentative metabolites and changing the gut microbiota of dogs.…”

The objective was to evaluate through three experiments the effects of a fine cassava fibre (CA: 106 μm) on kibble characteristics, coefficients of total tract apparent digestibility (CTTAD) of macronutrients, diet palatability and faecal metabolites and microbiota of dogs. Dietary treatments consisted of a control diet (CO), without an added fibre source and with 4.3% total dietary fibre (TDF), and a diet with 9.6% CA (106 μm), with 8.4% TDF. Experiment I evaluated the physical characteristics of the kibbles. The palatability test was evaluated in experiment II, which compared the diets CO versus CA. In experiment III, 12 adult dogs were randomly assigned to one of the two dietary treatments for 15 days, totalling six replicates/treatment, to assess the CTTAD of macronutrients; faecal characteristics, faecal metabolites and microbiota. The expansion index, kibble size and friability of diets with CA were higher than the CO (p < 0.05). Additionally, the CA diet presented higher palatability than the CO (p < 0.05) but did not affect CTTAD except for those of fibre (p > 0.05). Moreover, a greater faecal concentration of acetate, butyrate and total short-chain fatty acids (SCFA) and a lower faecal concentration of phenol, indole and isobutyrate were observed in dogs fed the CA diet (p < 0.05). Dogs fed with the CA diet presented a greater bacterial diversity and richness and a greater abundance of genera considered to be beneficial for gut health, such as Blautia, Faecalibacterium and Fusobacterium when compared to the CO group (p < 0.05). The inclusion of 9.6% of a fine CA improves the expansion of kibbles and diet palatability without affecting most of the CTTAD of nutrients. Besides, it improves the production of some SCFA and modulates the faecal microbiota of dogs.

“…Fibre can have different effects on the extrusion of dog food (Monti et al, 2016), nutrient digestibility, faecal quality, intestinal microbiota, food preference and gastrointestinal transit time of dogs, depending on the source and its inclusion level (Koppel et al, 2015;Pacheco et al, 2021;Volpe et al, 2021).…”

The use of fruit fibres as a way of reusing industrial waste is attractive and necessary, increasing the efficiency and reducing the environmental impact of the industry. This study characterized guava fibre as a fibrous ingredient and evaluated its effects when included in extruded diets for dogs on nutrient digestibility, faecal traits, fermentation products, gastrointestinal transit time and palatability. Four diets were formulated: CO (control diet, no fibrous ingredients added), GF3 (3% guava fibre), GF6 (6% guava fibre) and GF12 (12% guava fibre). The guava fibre was added to diets in replacement of maize, with small adjustments in the other ingredients to ensure similar contents of protein and fat. The diets were fed to 24 adult Beagle dogs (6 per diet) during 15 days for adaptation followed by 15 days for assessment of digestibility, fermentation end products and gastrointestinal transit time. The palatability of G6 and G12 treatments was evaluated against the CO by the two‐pan test. Results were compared by analysis of variance and polynomial contrasts according to the guava fibre inclusion level (p < 0.05). The addition of guava fibre did not change nutrient intake except for the increase on dietary fibre (p < 0.001). Fibre inclusion resulted in a quadratic reduction in total tract apparent digestibility for dry matter, organic matter, crude protein and crude energy (p < 0.001), and on the metabolizable energy content of the foods (p < 0.001). Guava fibre addition did not change the faecal concentration of ammonia, lactic acid, faecal pH and branched chain fatty acids but it decreased acetic and propionic acids concentration (p < 0.01). The inclusion of 12% guava fibre did result in a faster transit time (p = 0.046) compared to the control diet. Guava fibre can be characterized as a novel insoluble non‐fermentable fibre source that could be safely used in levels up to 12% in canine extruded diets.
