“…The dietary inclusion of CA resulted in an increase in the amperage and screw speed in the extruder barrel, which contributes to the energy input and retention time of the dough (Alvarenga et al, 2018; Monti et al, 2016; Riaz, 2000). Similar results were also observed by Souza et al (2022) evaluating 12% of a coarser CA (125 µm) in diets for dogs. The increase in the amperage and screw speed in the extruder barrel with the dietary inclusion of CA can be attributed to the non‐plastic and rigid nature of some IFs, conferring increased resistance to mass flow (Monti et al, 2016; Souza et al, 2022).…”

“…Cassava fibre (CA) is a byproduct of the extraction of starch from cassava roots, obtained by drying and grinding the cassava cortex. It presents an average concentration of 41% total dietary fibre (TDF), 38% of insoluble fibre (IF) and 2.9% of soluble fibre (SF) and can be a new fibre source to pet food formulation (Souza et al, 2021, 2022).…”

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.

“…Pet food companies produce diets with reduced calorie density and/or energy content by reducing fat and supplementing with fibrous ingredients that are aimed to reduce body weight and help with weight management [ 2 , 3 , 5 , 14 ]. The animal’s digestive enzymes cannot digest fiber, unlike starch in the diet; for this reason, it contributes few, if any, calories.…”

“…Previous studies have demonstrated that poorly fermented cellulose has a moderate capacity to bind water and can decrease the transit time of food and digestibility [ 17 ], as well as increase fecal output in dogs [ 18 , 19 , 20 ]. However, cellulose is expensive when compared to other fiber sources [ 5 , 14 ]. Thus, there is a need to find alternative fiber sources.…”

Lignocellulose (LC) might be used as a substitute fiber source for dogs as a strategy to decrease energy density and enhance gastrointestinal functionality. The objective of the present study was to compare the effects of including different levels of LC on apparent nutrient digestibility and fecal parameters (dry matter (DM), fecal score, and daily fecal output), as well as fecal fatty acid concentrations. Four diets were tested: control diet (no supplementation of LC; LC0), and three control diets diluted with increasing levels of LC: 1, 2, and 4% (LC1, LC2, and LC4). Six Beagle dogs (BW 17.1 kg ± 1.22) participated in a crossover experimental design. Before each experimental period, five days were used as a wash-out period. The fecal consistency was scored based on a 5-point scale (1 = very hard; 2 = solid, well-formed “optimum”; 3 = soft, still formed; 4 = pasty, slushy; and 5 = watery diarrhea). The results demonstrated that the organic matter apparent digestibility (p = 0.01) and nitrogen-free extract (NFE) (p < 0.01) was significantly lower for dogs fed LC4 compared to those fed LC0. Dogs fed LC2 and LC4 had a lower fecal consistency score (2.39 and 2.18, respectively; p < 0.05). The fecal DM was significantly the highest (p < 0.01), and the daily fecal output on fresh matter was lower (p < 0.05) when dogs were fed the LC4 diet compared with the LC0 diet. Including LC at 1% in the diet resulted in significantly higher fecal acidic pH levels. However, no differences among treatments were noted regarding fecal fatty acid concentrations.
