Morphometric and Bioacoustic Study of the Ornamental Gaga’s Chicken (Ayam Ketawa) from Kebayoran Lama and Pinrang

Abstract

The aim of study was to distinguish two types of Gaga’s chicken, Gallus gallus domesticus, namely dangdut type and slow type based on morphometric and bioacoustics characters.  Twenty samples were collected from Pinrang, South Sulawesi, and the rest of seven samples were collected from Kebayoran Lama, Southern Jakarta, respectively. The Gaga’s chicken body weight was not significant different from Pinrang and Kebayoran Lama either in “slow type” or “dangdut type”. In contrast, the neck bone length of the “dangdut type” from Pinrang was longer (P<0.05) than Kebayoran Lama. Based on bioacoustic analysis of “dangdut type” shown more beats (4-7 times) than “slow type” (3-5 times).
