Performance Analysis in Quantitative Local Ducks in Kediri Regency East Java

The livestock sector is one of the potentials in Indonesia, including duck farming. The duck population in Kediri District in 2022 amounted to 367,987 heads. This research was conducted in 5 subdistricts in Kediri District including Mojo Subdistrict, Ringinrejo Subdistrict, Wates Subdistrict, Ngasem Subdistrict, and Gampengrejo Subdistrict. The variables observed in this research include quantitative traits (femur length, tibia length, shank length, shank circumference, wing length, sternum length, chest width, and chest depth). The differences in the results of this study are influenced by environmental factors and genetics. The conclusion of this study is that the morphometric measurement interval (quantitative traits) of local ducks in each sub-district in Kediri District varies greatly because it is influenced by several factors including the environmental conditions of each sub-district, feed consumption, maintenance methods, and age. The measurement results show that local ducks in Kediri District are still cultivated by farmers and have a variety of sizes. The suggestion of this research is that morphometric measurements (quantitative traits) of local ducks should be carried out in all sub-districts in Kediri District so that it can be known that the body size of ducks in Kediri District is very diverse.
