Abstract
Extruded pet foods were prepared by extrusion process incorporating dry rendered spent hen meal (SHM) at 10 and 20% levels, and packed in LDPE bags before storage at room temperature (35 ± 2°C) up to 45 days. The colour of the pet foods was uniformly brown with pleasant meaty odour. The thiobarbituric acid, tyrosine values, free fatty acid content and acid value and total bacterial counts increased gradually during storage but E.coli, Salmonella spp, Clostridium spp, Staphylococci spp and fungi were not detected during storage. The pet owners rated the pet foods as good. The body weight of the adult pet dogs did not decrease during the feeding trial of one month and the health condition of pets was good. The cost of production per kg of pet food containing 10 and 20% SHM was Rs 18.00 and Rs 22.75, respectively. It was concluded that a pet food (whole meal) with good nutritive quality and palatability to dogs can be prepared by incorporating 10–20% of spent hen meal which can be safely stored up to 45 days at room temperature.
