    Locally produced fish hydrolysate and oil from the agrifood sector comprises a sustainable solution both to the problem of fish waste disposal and to the petfood sector with potential benefits for the animal’s health. This study evaluated the effects of the dietary replacement of mainly imported shrimp hydrolysate (5%) and salmon oil (3%; control diet) with locally produced fish hydrolysate (5%) and oil (3.2%) obtained from fish waste (experimental diet) on systemic inflammation markers, adipokines levels, cardiac function and fecal microbiota of adult dogs. Samples and measurements were taken from a feeding trial conducted according to a crossover design with two diets (control and experimental diets), six adult Beagle dogs per diet and two periods of 6 weeks each. The experimental diet, with higher docosahexaenoic (DHA) and eicosapentaenoic (EPA) acids contents, decreased plasmatic triglycerides and the activity of angiotensin converting enzyme, also tending to decrease total cholesterol. No effects of diet were observed on serum levels of the pro-inflammatory cytokines interleukin (IL)-1β, IL-8, and IL-12/IL-23 p40, and of the serum levels of the anti-inflammatory adipokine adiponectin. Blood pressure, heart rate and echocardiographic measurements were similar between diets with the only exception of left atrial to aorta diameter ratio that was higher in dogs fed the experimental diet, but without clinical relevance. Diet did not significantly affect fecal immunoglobulin A concentration. Regarding fecal microbiome, Megasphaera was the most abundant genus, followed by Bifidobacterium , Fusobacterium , and Prevotella , being the relative abundances of Fusobacterium and Ileibacterium genera positively affected by the experimental diet. Overall, results from the performed short term trial suggest that shrimp hydrolysate and salmon oil can be replaced by protein hydrolysate and oil from fish by-products without affecting systemic inflammatory markers, cardiac structure and function, but potentially benefiting bacterial genera associated with healthy microbiome. Considering the high DHA and EPA contents and the antioxidant properties of fish oil and hydrolysate, it would be worthwhile in the future to assess their long-term effects on inflammatory markers and their role in spontaneous canine cardiac diseases and to perform metabolomic and metagenomics analysis to elucidate the relevance of microbiota changes in the gut.

    The inclusion of protein hydrolysates from animal by-products in petfood may enhance the industry’s sustainability, while contributing to dogs’ health due to their nutritional and functional properties. However, inconsistent results of protein hydrolysates on gut microbiota, immune responses, among other health parameters, have been observed in dogs. This study aimed to evaluate the effects of diets supplemented with 5% shrimp hydrolysate, compared to non-supplemented diets, on hematological parameters, serum chemistry profile, innate and adaptive immune function, and fecal microbiota composition in adult Beagle dogs during a 12-week feeding trial. Dietary inclusion of shrimp hydrolysate decreased blood eosinophils ( P  = 0.017) and glucose levels ( P  = 0.023), while increasing levels of white blood cells ( P  = 0.002), platelets ( P  = 0.038), neutrophils ( P  = 0.036), and CD4 + ( P  < 0.001) and CD8 + T cells ( P  < 0.001) single producers of tumor necrosis factor-alpha. It also led to a more extensive proliferation of CD4 + T cells in response to LipL32 antigen ( P  = 0.020) and to a decrease in superoxide production in stimulated cells ( P  = 0.002). Additionally, supplemented diets increased Oscillospiraceae ( P-adj  = 0.005) and Clostridia ( P-adj  = 0.017) abundance, and decreased such of Sellimonas ( P-adj  = 0.025). Overall, the results indicate that diet supplementation with shrimp hydrolysate at 5% modulates the immune response and fecal microbiota, highlighting its potential to be included in hypoallergenic and gastrointestinal diets, and in diets for diabetic dogs.
