“…The inclusion of fibre in diets has been used for several pet animals to reduce the energy content of their food (Earle et al., ) and to favour the control of energy intake in diets for obese dogs and cats (Laflamme, ; Vasconcellos et al., ). Increased food fibre amount may have potential positive effects, such as a reduction in the glucose, cholesterol and triglycerides plasma concentration, and a greater stimulation to the physical mechanisms that regulate satiety, which could potentially prevent obesity and provide long‐term health benefits (Carciofi and Jeremias, ). Although the effect of adding fibre to reduce food energy content is well known for poultry (Bertechini, ), fibre addition has not been evaluated for psittacines.…”

Considering the increased incidence of obesity and metabolic diseases in caged psittacines, the effect of fibre and food processing was evaluated in the Blue-and-gold macaw. Four food formulations (0%, 7%, 14% and 21% of sugarcane fibre) processed by pelleting or extrusion were studied, resulting in eight diets. To study digestibility, 48 macaws housed in pairs in cages was used in a block design. Subsequently, diets containing 0% or 21% sugarcane fibre, pelleted or extrude was fed for 4 months to evaluate energy intake and blood metabolites. A 2 × 2 × 2 (two fibre levels, two food processing methods and two genders) factorial arrangement with subplots (beginning and end) was used. When differences were detected in anova's F test, data were submitted to polynomial contrasts in the first experiment and to orthogonal contrasts in the second experiment (p < 0.05). Fibre addition reduced protein, fat and energy (p < 0.001) digestibility in both food processing. Pelleted foods presented higher dry matter digestibility and food metabolisable energy (ME) than the extruded ones (p < 0.05). Fibre addition or the type of processing did not change ME ingestion (p > 0.05). The macaws gained body weight (p < 0.05) regardless of the diet (p > 0.05), but females fed with the high-fibre diets did not gain weight (p > 0.05), suggesting a low food ME (12.5 kJ/g).The substitution of the original diet (sunflower seeds, fruits and cooked maize) by the experimental foods decreased the basal (12-h fast) concentrations of glucose, cholesterol and triglycerides (p < 0.001). The consumption of pelleted diets reduced serum glucose and cholesterol (p < 0.05). Results suggest that the pelleted diets were more beneficial and can be used to reduce blood metabolites related to metabolic disorders that are commonly observed in macaws.

Avaliou-se o emprego de silagem ácida de vísceras de tambaqui para alimentação de cães jovens. As variáveis estudadas foram o estado geral, o ganho de peso vivo, o escore corporal e fecal, a consistência e odor das fezes e a função hepática e renal dos animais. A ração foi composta com 46% de silagem e calculada para gerar níveis nutricionais iguais aos registrados no rótulo da ração comercial para filhotes e compatível com a recomendação para a idade dos animais, ou seja, 26% PB, de 1,0 a 2,0% de Cálcio, 0,9% de Fósforo e 3295 kcal kg-1 EM. O período experimental foi de 52 dias sendo que as amostras de sangue, para avaliação bioquímica, foram coletas no 53º dia após o jejum de 12 horas. O uso da silagem na alimentação dos cães foi satisfatório não diferindo em relação a todas as variáveis estudadas, em relação ao grupo controle. Este estudo, de caráter exploratório, gera o indicativo de uso da silagem de resíduos de peixes a ser empregado como fonte protéica na formulação de ração para cães.

“…Rice is a functional ingredient regularly used in extruded dog food, due to its high digestibility. But, with the growing pet population over the past years, as well as the pet food industry, the search for alternative ingredients to provide nutritional quality and functional properties is becoming increasingly important [2].…”

Effect of partial substitution of rice with sorghum and inclusion of hydrolyzable tannins on digestibility and postprandial glycemia in adult dogs

Sorghum is used as a substitute for rice in dog food, owing to its nutritional similarity and low cost. However, its use has been associated with negative effects, like a reduction in palatability, digestibility, and enzyme activity, which can decrease nutrient absorption. The presence of condensed tannins (CT) in sorghum may cause these effects. Another tannin group, the hydrolysable tannins (HT), is known for its antioxidant properties. Research has shown the nutritional effects of sorghum on dogs, but the effect of HT on dogs remains unknown. We evaluated the effects of substituting rice with sorghum containing CT and inclusion of commercial extract of HT on digestibility, fecal and urinary characteristics, and postprandial blood glucose levels in adult dogs. Eight adult Beagle were randomly subjected to 4 treatments: (R) 50% rice; (RS) 25% rice + 25% sorghum; (RHT) 50% rice + 0.10% HT; (RSHT) 25% rice + 25% sorghum + 0,10% HT. Tannins did not affect food intake. The digestibility of dry matter, organic matter, crude protein (CP), acid hydrolyzed fat, gross energy, and metabolizable energy (ME) decreased with sorghum inclusion (P < 0.05). Greater fecal dry matter was observed with the RHT diet. HT associated with sorghum, RSHT diet, reduced ME (P < 0.05). Sorghum inclusion enhanced fecal output, without altering fecal score (P > 0.05). No alterations in urinary characteristics were observed. Sorghum and HT did not affect the postprandial blood glucose response measured by the area under the curve (P > 0.05). The substitution of rice by sorghum decreased CP digestibility and ME of the diets. Sorghum can be considered as a source of carbohydrates with lower digestibility of protein and energy than rice. HT may potentiate the effect of CT, but more research is needed to evaluate its potential use in dog nutrition.
