“…Interestingly, product B showed no detectable amounts of any FA typical for fish oil addition. Ahlstrøm et al [28] reported substantial differences in FA content in commercial dry foods for dogs (mainly puppy foods), suggesting that no DHA or eicosapentaenoic acid (C20:5; EPA) practically reflects the absence of marine oils or products in the kibble.…”

Selected quality and oxidative stability parameters of the lipid fraction were analyzed in four complete dry dog foods with different main animal-derived ingredients. The measurements were taken at the time of bag opening and repeated after 7 months of continuous storage in normal room conditions. Fatty acid (FA) content and acid value (AV) were determined, followed by subsequent pressure differential scanning calorimetry (PDSC) measurements. From the resulting PDSC exotherms, maximum induction time (s max ) was determined and used for assessing the oxidative stability. The study revealed changes in lipid quality and oxidative stability of dry dog foods that appeared during storage. Results of FA and AV assays showed specificity and marked quality differences of lipid ingredients declared as used in the production process. Product with the lowest content of polyunsaturated FA had the highest oxidative stability. PDSC appeared to be an effective method for the analysis of lipid oxidation in pet foods.

“…The selection of the two linoleic acid concentrations tested in this study (4 g/Mcal and 10 g/Mcal) was based on the range observed in typical pet foods on the market. Many grocery products contain linoleic acid around the 4–5 g/Mcal range, whereas higher quality feeds typical have linoleic acid spanning 7–10 g/Mcal [ 1 ]. The 10 g/Mcal concentration, therefore, lies at the top end of the premium type commercial diets.…”

Linoleate-enriched diet increases both linoleic acid esterified to omega hydroxy very long chain fatty acids and free ceramides of canine stratum corneum without effect on protein-bound ceramides and skin barrier function

Few studies have investigated the influence of increased amounts of dietary linoleic acid on the epidermal lipid biochemistry and TEWL in healthy subject. The influence of dietary linoleic acid on canine stratum corneum (SC) lipids was studied by feeding two groups of five dogs differential amounts of linoleic acid (LA) for three months. SC was harvested by tape stripping and lipids were analyzed by thin-layer chromatography and mass spectrometry. The dogs that were fed the higher concentration of LA showed high increases in the contents of both linoleic acid and free ceramides in the SC, whereas the protein-bound ceramide content was unchanged. Acylacids that represent the esterified form of linoleic acid in omega hydroxy very long chain fatty acids (ω-OH VLCFA) accounted for most of the elevation of LA, whereas the concentration of the free form was not significantly changed. Corroborating the absence of change in the protein-bound ceramides content of healthy dogs SC, TEWL was nearly unaffected by the linoleic acid-enriched diet.

“…30 The mink, which is a strict carnivore, has become a common model animal for evaluation of quality of feed ingredients for dogs and cats, and precise and accurate procedures have been developed in this species. [31][32][33][34][35] The results obtained with mink correlate closely with digestibility in dogs and blue foxes. [35][36][37] In this study, we utilized mink as a model animal to evaluate the safety and assess the potential of Antarctic krill meal as a supplementary protein and lipid source in commercial pet foods.…”

Background: Antarctic krill meal is rich in protein, fat, and omega-3 fatty acids. Two experiments were performed to evaluate nutritional and health aspects of Antarctic krill meal in the diet of reproducing mink to determine whether such a meal can be used as a pet food ingredient. Materials and methods: The first experiment assessed the digestibility and palatability of Antarctic krill meal. The second investigated effects of four dietary inclusion levels of Antarctic krill meal (0%, 9%, 17%, and 35% of dry matter) on the reproductive performance and health of female mink (16 per group) when substituted for high-quality fishmeal prior to mating through gestation, parturition, lactation, and early kit growth (117 days). The diets are named K0, K9, K17, and K35, respectively. Results: Antarctic krill meal showed high protein and fat digestibility (85% and 98%, respectively). No effect of the test material on the reproductive performance of maternal animals was observed. Relative organ weights of maternal animals were the same for the K0, K9, and K17 groups, whereas K35 animals showed higher values for stomach, intestine, and spleen weights. Likewise, results of hematology, clinical chemistry, and histomorphological analyses did not differ between animals fed with K0, K9, and K17 diets. Animals in the K35 group showed some changes in the liver and gastrointestinal tract, clinical chemistry, and hematology compared to control animals. At weaning, body weight of kits in the K35 group tended to be lower than that of the K0 group, which may have been related to the larger initial litter size of the K35 group. Conclusion: Antarctic krill meal has similar nutritional value as high-quality fishmeal and produces no adverse effects in reproducing female mink when included in feed at up to 17% of dry matter. The results suggest that Antarctic krill meal can be safely included in pet food.
