“…The values of digestibility coefficients, previously presented, can be considered typical of growing Arctic foxes aged four to five months, despite statistically significant differences between the control and experimental groups. These results are also consistent with the findings of other authors, regarding Arctic foxes Skrede, 1995, 1998;Gugołek et al, 1997;Lorek et al, 1999Lorek et al, , 2002Ahlstrom et al, 2000;Szymeczko, 2001;Dahlman et al, 2002;Matusevicius et al, 2004;Vhile et al, 2005a,b).

Three digestibility experiments on Arctic foxes were carried out. Control groups were fed standard diets (C1 and C2) composed of fresh or frozen animal by-products and steamed ground grain. Dry experimental diets (E1 and E2) contained animal meals, extracted meals and fat, were mixed with water prior to administration. In a preliminary experiment, the digestibility of dry diet E1 moistened with water for 15min and 24h was compared to determine the optimum moistening time during the experimental period proper. The preliminary experiment showed that moistening time had no significant effect on digestibility. In the main experiment, two independent digestibility trials were performed to compare the digestibility of diets fed to foxes during growth (C1 vs. E1) and fur development (C2 vs. E2). Better nutrient digestibility was noted for control diets, compared to experimental. The greatest differences were reported for total protein digestibility. Protein contained in meals undergoes denaturation during heat treatment, which reduces digestibility. It was found that the retention of nitrogen in relation to nitrogen digestion was higher in foxes fed experimental diets (E1 and E2).

Os grupos controles receberam dietaspadrão (C1 e C2) compostas por subprodutos de origem animal frescos ou congelados e sementes de cereais em grão. As dietas secas (E1, E2) usadas nos ensaios que continham farinha de origem animal e sementes em grãos extrudadas eram hidratadas antes de administradas. Em ensaio preliminar, avaliouse a digestibilidade da dieta seca E1, submetida a 15 minutos e a 24 horas de hidratação. Verificou-se que o tempo de hidratação não influenciou a digestão. No experimento principal, foram realizados dois ensaios para comparar a digestibilidade das dietas fornecidas às raposas no período de crescimento (C1 vs E1) e no desenvolvimento de pelo (C2 vs E2

“…In foxes, the digestion process requires the presence of enzymes (Oleinik, 1995;Szymeczko and Burlikowska, 1996). A comparative analysis of nutrient digestibility in Arctic foxes has been performed, among others, by Skrede (1995, 1998), Szymeczko (2001), Ahlstrom et al (2003), and Vhile et al (2005a).…”

“…Skrede and Ahlstrøm (1995) showed that apparent protein digestibility decreased from 88 to 84% in blue foxes when the carbohydrate level increased from 7.7 to 40% of dietary DM. Vegetable protein is often less digestible than animal protein (Ahlstrøm and Skrede, 1997), thus the high vegetable protein level in the experimental diet may also explain the low digestibility of protein.…”

Arctic foxes from Svalbard (ns4) and farmed blue foxes (ns4) was used in a digestibility experiment with a highcarbohydrate feed to add more information to the nutritional physiology of the arctic fox, and to compare its digestive capacity with that of the farmed blue fox. The arctic fox has a diet containing mainly protein and fat from mammals and birds, while farmed blue foxes have been exposed to an omnivorous dietary regime for more than 80 generations. The experiment showed in general no difference in digestive capacity for protein and fat between the foxes (P)0.05), but for carbohydrates, including starch and glucose, the blue fox revealed higher digestibility values. The superior digestive capacity for carbohydrates in blue fox might be a result of a long-term selection of animals digesting dietary carbohydrates more efficiently, or that an early age exposition to dietary carbohydrates has given permanent improvement of the carbohydrate digestion in the gut. ᮊ
