Tuna Red Meat as a Novel Ingredient in Pet Food for Dogs

Abstract

Red meat from tuna canning factory was used to develop a pet food for dogs. Feed was developed by mixing cooked, dried, and powdered red meat with cereal flours in varying proportion. The combination that gave maximum hardness for the feed was selected as optimum. The developed feed had a crude protein content of 20.2 ± 0.95% and crude fat content of 4.70 ± 0.37%. Analysis of mineral content showed that it is rich in macro minerals, including phosphorus (2843.67 ± 206 ppm), sodium (1333.54 ± 56 ppm), and calcium (400.04 ± 21 ppm). Amino acid content of the feed showed that it meets the dietary requirements of dogs in terms of threonine, methionine, histidine, lysine, arginine, and tryptophan. Polyunsaturated fatty acid content of the feed was dominated by linoleic acid, followed by DHA and EPA.
