Dietary protein sources and their effects on faecal odour and the composition of volatile organic compounds in faeces of French Bulldogs.

Article Synopsis
- The study investigates the odour of faeces in French Bulldogs, which is often a concern for dog owners due to excessive gas and strong smells stemming from undigested protein in their diets.
- Researchers formulated four different high-quality protein dog foods and conducted a sensory analysis alongside volatile organic compound (VOC) testing on the dogs' faeces over a 28-day period.
- The results indicated minimal overall changes in VOCs linked to dietary protein sources; however, the type of food did influence odour perception, with foods containing animal protein resulting in stronger odour ratings during sensory evaluation.
Benefits to microbial fermentation in the colon and as a consequence less flatulence can be promoted for the health of adult dogs according to the amount and protein source. The present study evaluated different protein sources in dry food for brachycephalic dogs regarding microbial fermentation and nutrient digestibility. Four dry dog foods with similar protein content were formulated for adult maintenance: poultry meal (PM) diet; wheat gluten (WG) diet; PM + WG diet; and PM + WG + hydrolysed protein (HP) diet.

Substrates used were citrus pectin (CP), fructo-oligosaccharides (FOS), guar gum (GG), sugar beet pulp (SBP) and wheat middlings (WM). Each substrate was incubated with faecal inoculum from five cats with three replicates for each substrate-cat combination.
