Zamboanga peninsula (ZamPen) native chicken is a purified Joloano breed currently propagated by Western Mindanao State University (WMSU). With the limited data present in this species, this research attempted to establish baseline data it terms of its proximate composition. From there, a comparative study between its cut-up parts and sex (hen and rooster), as well as with other native chickens (in the Philippines as well as in other parts in Asia) was also conducted. Findings reveal that there are significant differences in the proximate composition in the selected cut-up parts for both hen and rooster ZamPen native chickens, except for its ash composition of hen. In addition, a no significant difference exists in the proximate composition in the selected cut-up parts between hen and rooster, except moisture composition in the legs, total fat content in the legs, wings, thighs, as well as fiber composition for all its cut-up parts. When compared to other native chicken breeds, with the exemption of the Baicheng-You breed; both ZamPen native chicken hen and rooster were found to have a higher proximate composition in terms of protein content for all of its cut-up parts. This implies then that the ZamPen native chicken is a promising source of protein for all its cut-up parts.
