Abstract
The meat sector generates substantial quantities of offals and by-products, particularly from the expanding buffalo meat industry, which remain under utilised despite their high nutritional value. The present study aimed to develop a dry pet food incorporating buffalo liver meal (BLM), evaluate its sensory attributes and palatability in dogs, and assess its storage stability under aerobic conditions. Buffalo liver was processed into meal and incorporated into pet food formulations at different levels, with a soya-based product serving as control. Sensory evaluation revealed that products containing BLM had significantly higher meat odour intensity and overall acceptability; although appearance scores were lower due to darker colour. Palatability trials using adult dogs demonstrated a clear preference for BLM-based diets, with the formulation containing 30% BLM showing the highest intake ratio and daily intake. Based on sensory and palatability results, the 30% BLM product was selected for further evaluation. Proximate composition indicated high protein content and good nutritional quality. Storage stability studies conducted for 60 days at ambient temperature showed gradual increases in moisture, lipid oxidation, protein degradation indices, and microbial counts, though values remained within acceptable limits. Sensory quality remained acceptable up to 30 days. The study concludes that the incorporation of 30% buffalo liver meal is effective for producing a nutritious, palatable, and economically viable dry pet food, offering a sustainable avenue for the utilisation of buffalo offal and by-products.
