This study investigated the use of hydrolyzed feather meal as a substitute for poultry meat in dog diets. Two groups of four English Setters, two male and two female each, were fed two different diets over 45 days. The control group was fed with poultry meal as the protein source and one treated group with a mix of poultry meal and hydrolyzed feather meal. Body weight, body condition, muscle condition, and fecal consistency scores did not differ between groups and sex. Beta diversity varied significantly between the control and treated groups, as well as between sex. Fourteen bacterial taxa were different between diet and 25 between sex. Overall, the study highlights the influence of hydrolyzed feather meal and sex on gut microbiota in dogs, suggesting potential implications for dog nutrition and microbiome research.

Abstract

This study investigated the use of hydrolyzed feather meal as a substitute for poultry meat in dog diets. Two groups of four English Setters, two male and two female each, were fed two different diets over 45 days. The control group was fed with poultry meal as the protein source and one treated group with a mix of poultry meal and hydrolyzed feather meal. Body weight, body condition, muscle condition, and fecal consistency scores did not differ between groups and sex. Beta diversity varied significantly between the control and treated groups, as well as between sex. Fourteen bacterial taxa were different between diet and 25 between sex. Overall, the study highlights the influence of hydrolyzed feather meal and sex on gut microbiota in dogs, suggesting potential implications for dog nutrition and microbiome research.
