PREPARATION OF LEAST COST DOG BISCUIT BY USING AVAILABLE FEED INGREDIENTS

Abstract

The current research work was undertaken for a period of six months to screen out the available feed resources at CMP (Chittagong Metropoliton) areas usable for dog biscuit. The two areas found suitable for this purpose viz. Jhawtola bazaar and CVASU on the basis of their availability. Four different types of samples were chicken intestine, chicken intestine with skin, fish scale and dead chicken carcass collected from the study areas. Chemical analyses of the samples were carried out in for dry matter (DM), crude protein (CP), crude fiber (CF), nitrogen free extracts (NFE), ether extracts (EE) and total ash in the animal nutrition laboratory at Chittagong Veterinary and Animal Sciences University, Chittagong, Bangladesh. Results indicated that, all samples had substantial amount of proximate components that might have been used as alternative feed resource in dog food. Among them the dead chicken meal found to be better for the preparation of dog biscuit as compared to the chicken intestine or fish scale. The another trial was conducted to test the prepared dog biscuit with the objectives of formulating a least cost palatable dog biscuit using locally available ingredients in Bangladesh, which confirm the main nutritional requirements and to determine its influence on growth rate of local breeds. A total of 18 puppies (between 08-12 weeks of age) were used in this study. Feed offered, body weight gain, metabolic profile test, serum electrolyte concentrations and hematological analysis were done on weekly basis to determine nutritional status. It was found that the body weight gain and feed intake had a significant (P<0.05) and positive relationship. It was found that the weight gain of puppies which were fed using homemade food was 1.62 ± 0.04 kg whereas 2.02 ± 0.27 kg and 2.11± 0.13 kg was the weight gain of puppies which were fed using commercial food and prepared biscuits, respectively. Result of metabolic profile test, serum electrolyte concentration, hematological analysis and digestibility revealed no significance difference between groups those were fed commercial food and prepared biscuits and cost comparison reveal prepared biscuit was too economic than the commercial food. In conclusion, both commercial food and prepared biscuits showed similar result in terms of weight gain, metabolic profile test, serum electrolyte concentration, hematological analysis and digestibility.
