“…Differences between manufacturer-reported maximum moisture concentrations and measured moisture concentrations in the present study were consistent with results of other studies, 26,40,41 as were differences between the reported maximum CF and measured TDF concentration. 26,28,40 In canned diets only, reported maximum CF concentration was not different than measured IDF concentration, suggesting this value could potentially be used to estimate IDF content in similar diets.…”

“…26,28,40 In canned diets only, reported maximum CF concentration was not different than measured IDF concentration, suggesting this value could potentially be used to estimate IDF content in similar diets. However, this was not supported by a previous study 26 for a sample of canine maintenance diets. Reported CF concentrations in excess of measured TDF and IDF concentrations in canned diets were previously determined in a study 40 evaluating fiber content and composition in feline diets for management of obesity and diabetes mellitus.…”

Diets provided a range of TDF concentrations and compositions; veterinarians should request TDF data from manufacturers, if not otherwise available. Consistent responses to dry and canned versions of the same diet cannot necessarily be expected, and diets with the same indications may not perform similarly. Many diets may not provide adequate fat restriction for treatment of dietary fat-responsive disease.

“…In the current study, although using a smaller number of diets, higher in fibre than average dog feed, each percentual unit increase of CF resulted in a TDF increment of two percentual units. In another study with dog food, Farcas et al (2013) found that CF under-represented TDF and was not a good indicator of fibre in the diet, similar to the data presented here. The relatively high correlation observed in our study may be explained by inclusion of similar fibre sources in the test diets.…”

SummaryFibre is an important nutrient for rabbit health, and, on commercial pet rabbit packaging, it is labelled as crude fibre (CF). In several species, it is considered that CF is not an accurate representation of the fibre content in feedstuffs. The objective of this study was to compare the CF stated on the label (CFL) with laboratory analysis of CF (CFA) and the analysed content of total dietary fibre (TDF) in different commercial pet rabbit feeds. We selected 15 commercial diets and analysed CF and TDF. A mixed model was used to evaluate differences between CFL, CFA and TDF, and linear regression was performed to study the correlation between CFL and CFA with TDF. CFA and CFL were not significantly different (p = 0.836) in the feeds studied, and both were lower than TDF (p < 0.001). The correlations between TDF and both CFA and CFL were significant (p < 0.001 and p = 0.02, respectively), but the correlation was better with CFA (R = 0.86) than with CFL (R = 0.53). As expected, TDF content was higher than CF content, an average of two times. These results suggest that the CF content in rabbit diets reported on the label is not an appropriate indicator of their total fibre content, although further work with a larger sample size is required to confirm these results.

“…Another recent study (FARCAS et al, 2013) evaluates the differences between maximum crude fiber concentrations and total dietary fiber concentrations (which would be the gold standard method currently) in 20 dry and 20 moist non-therapeutic foods for dogs, and the authors concluded that in lack of information on total dietary fiber concentration (as is the case of our study) no crude fiber concentration appears to be a particularly reliable indicator of fiber concentration and composition of a canine diet.…”

Common protein sources used in the manufacturing of diets for dogs are derived from by-products, which may have reduced digestibility depending on the source. This study evaluated the effect of the addition of a protease, the papain enzyme, as a supplement to extruded diets on palatability, nutrient digestibility, and fecal production and quality of dogs. A diet was formulated with poultry by-product meal, meat and bone meal, and feather meal as protein sources. This formula was divided into three isonutrient diets: one negative control (NC), without enzymes; treatment one (EZ1) with addition of 855.000 UI of papain per kilogram of diet, and treatment two (EZ2) with addition of 2.280.000 UI of papain per kilogram of diet, both added before extrusion. The experiment followed a randomized block design, with two blocks of nine animals (three animals per treatment in each block), 18 dogs in total, and six replicates per treatment. Data were submitted to analysis of variance and the means of three treatments were compared by polynomial contrasts (P < 0.05). No differences in the coefficients of total tract apparent digestibility of nutrients nor changes in palatability, pH, and fecal production among treatments were found with the addition of different doses of enzyme to the diets (P > 0.05). The fecal score was reduced with increased addition of enzyme (P < 0.05). Keywords: Additive. Canine. Digestibility. Protein. ResumoAs fontes comuns de proteína utilizadas na fabricação de rações para cães são oriundas de coprodutos, os quais podem apresentar digestibilidade reduzida de acordo com a fonte. Este estudo avaliou os efeitos da adição da enzima papaína em dietas secas e extrusadas na palatabilidade, digestibilidade dos nutrientes, qualidade e produção fecal de cães adultos. Uma dieta foi formulada contendo farinha de vísceras de frango, farinha de carne e ossos e farinha de penas hidrolisadas como fontes proteicas. Esta foi posteriormente dividida em três dietas isonutrientes: controle negativo (CN) sem adição da enzima; adição de 855.000 UI de papaína por quilograma de ração (EZ1); e adição de 2.280.000 UI de papaína por quiilograma de ração (EZ2), ambas adições feitas antes da extrusão. O experimento seguiu delineamento em blocos casualizados, com dois blocos de nove animais (três animais por tratamento em cada bloco), totalizando 18 cães, e seis repetições por tratamento. Os dados obtidos foram submetidos a análise de variância, com as médias dos três tratamentos comparadas por contrastes polinomiais (P < 0,05). Não foram verificadas diferenças nos coeficientes de digestibilidade aparente dos nutrientes ou mesmo alterações na palatabilidade, pH e produção de fezes entre os tratamentos com diferentes inclusões de enzima (P > 0,05). Apenas o escore fecal reduziu com o aumento da adição da enzima (P < 0,05). Palavras-chave: Aditivo. Canino. Digestibilidade. Proteína.
