ABSTRACT
The study was conducted to evaluate the nutritional status of unconventional feed resources (UCFR) available in the Chattogram district. Unconventional feed resources refer to all those feeds that have not been traditionally used in another feeding and or are not normally used in commercially produced rations for livestock and poultry. A total of four tree leaves namely Jackfruit (Artocarpus heterophyllus), Mango (Mangifera indica), Banyan (Ficus benghalensis), and Mandar (Erythrina fusca) were considered for proximate analysis in the Animal Nutrition Laboratory, Department of Animal Science and Nutrition, Chattogram Veterinary and Animal Sciences University, Bangladesh. The laboratory analysis was performed according to the standard analytical procedure of the Association of Official Analytical Chemists (AOAC). The results indicated that the highest Dry mater (DM %) was in Jackfruits leaves whereas the lowest Dry matter (DM %) was in Mandar leaves. The highest Moisture % was in Mandar leaves whereas the lowest Moisture % was in Jackfruits leaves. The highest Crude protein (CP %) was in Mandar leaves whereas the lowest Crude protein (CP %) was in Mango leaves. The highest Crude fiber (CF %) was in Mandar leaves whereas the lowest Crude fiber (CF %) was in Banyan leaves. The highest Ether extract (EE%) was in Mango leaves whereas the lowest Ether extract (EE%) was in Jackfruit leaves and the highest Total Ash (TA%) was in Banyan leaves whereas the lowest Total Ash (TA%) was in Mandar leaves. In conclusion, the nutritional status of all tree leaves showed a higher Crude protein, Crude fiber, Ether extract, and Total Ash content. Therefore, these tree leaves can be used as a potential source of nutrients in livestock and poultry feed as well.
