“…It was also observed that water activity and diet humidity proportionally increased with increasing water addition to the conditioner. Water activity is an indication of food preservation as it is directly related to fungal growth (Brito et al, 2010), and therefore, special care should be taken during the drying step of foods manufactures with higher water inclusion levels in the conditioner.…”

The objective was to evaluate the effect of adding increasing water levels in conditioner on kibble's physicochemical characteristics and diet digestibility in dogs. Five adult dogs were used, who consumed diets containing: 1072, 1182, 1293, 1444, and 1565 kg of water/ hour added in conditioner. The design was a Latin Square (5 x 5) and the data were subjected to analysis of regression and correlation. The inclusion of up to 1565 kg of water/ hour in conditioner presented negative correlations (P <0.05) with hardness and density and positive with the water activity, moisture, porosity, and degree of starch gelatinization of kibbles. However, the digestibility and the metabolizable energy of the diets did not are affected by the amount of water added in the conditioner (P> 0.05). Furthermore, the intermediate addition of 1293 kg of water / hour in conditioner resulted in kibbles with larger pores, and increased up to 1565 kg of water / hour result in smaller pores providing lower density and hardness and an increase in starch gelatinization. However, it does not affect the diet digestibility in dogs.

“…Faecal pH was measured in a digital pH meter (331, Politeste Instrumentos de Teste Ltda, São Paulo, SP, Brazil) using 3.0 g of fresh faeces diluted in 30 mL of distilled water. The ammonia concentration was determined according to the method described by Brito et al [34].…”

Background: Direct-fed microbials (DFM), such as Bacillus subtilis and Bacillus licheniformis, may improve gut functionality of the host by favouring non-pathogenic bacteria and reducing the formation of putrefactive compounds. The aim of this study was to assess the nutrient digestibility, faecal characteristics and intestinalfermentation products in dogs fed diets with Bacillus subtilis and Bacillus licheniformis. Sixteen dogs were randomly divided into two groups. Every eight dogs were fed with the control diet or the diet with the addition of 62.5 g of DFM (B. subtilis and B. licheniformis)/ton. Diets were provided throughout a 20-day adaptation period, followed by 5 days of total faecal collection. Nutrient digestibility and the metabolisable energy of the diets, plus the dogs' faecal characteristics and intestinal fermentation products were assessed. Results: There were no differences in nutrient digestibility (P > 0.05). However, DFM supplementation improved faecal score and resulted in less fetid faeces (P < 0.001). DFM inclusion reduced (P < 0.05) the biogenic amines concentration: putrescine, spermidine and cadaverine, besides the concentration of phenols and quinoline. Conclusions: The use of B. subtillis and B. licheniformis as DFM reduce the concentration of nitrogen fermentation products in faeces and faecal odour, but the digestibility of nutrients is not altered in dogs.

“…Fecal pH was determined in 2.0 g fresh feces diluted in 20 mL distilled water, using a digital pHmeter (331, Politeste Instrumentos de Teste LTDA, São Paulo, SP, Brazil). Fecal ammonia content was determined according to Brito et al (2010) in 5 g fresh feces, which were incubated in a 500-mL lidded glass balloon with 250 mL distilled water for one hour. Three drops of octaethyl alcohol (1-octanol) and 2 g magnesium oxide were then added.…”

Addition of zeolite to caninedietscan improve fecal characteristics, reducing its moisture and odor. The objective of this study was to evaluate the effects of an increasing dietary inclusion of zeolite on nutrient and energy digestibility, fecal characteristics, and diet palatability for dogsfed diets containing high soybean meal level. Two experiments were performed. The first experiment evaluated the effect of increasing concentrations (0, 10, 20, 30, 40, or 50 g/kg) of zeolite (clinoptilolite) in extruded dog foods on diet digestibility and fecal quality. Six adult dogs were distributed to treatments arranged in a 6 x 6 Latin square design. The second assessed the effect of 20 or 50 g clinoptilolite per kg of diet on food palatability, where in 20 dogs were distributedinto two tests, in a completely randomized experimental design (0 vs.20 g/kg and 0 vs. 50 g/kg zeolite). Despite the small variation, dietary zeolite inclusion reduced diet metabolizable energy content (15.4 to 14.7 MJ/kg, P < 0.05) and the coefficient of total tract apparent digestibility of dry matter (0.773 to 0.740, P < 0.05). Fecal dry matter (fDM) content increased as zeolite concentrations increased (30.4% to 36.1%, P < 0.05), but fecal score had no effect. Zeolite concentrations caused no changes (P > 0.05) in ammonia nitrogen, sialic acid, fecal pH,or diet palatability.The inclusion of up to 50 g natural clinoptilolite per kg of diet increases fDM content, maintains adequate fecal score and has no negative impact on diet palatability.
