Morphometric and bioacoustic analysis Gaga chicken (Gallus gallus domesticus) at Bangkalan, Kamal Madura

摘要

Gaga chicken was known as local chicken, which has potential in the business of ornamental chicken in Indonesia. Gaga chicken has two types crowing sound. Three-dangdut types and seven slow types were collected from several stockbreeding in Bangkalan, Kamal Madura. The aim of the research is to investigate the biodiversity of Gaga' chicken based on bioacoustics and morphometric measurement. The data were analyzed by Mann Withney analysis. The variables measured were neck length, body weight, femur length, tibia length, shank length, shank diameter, superior maxilla, wing length, comb height, the third length, and chest bone length. The parameters were measured, recorded, and analyzed for crowing duration and number of crowing using the voice recording tool and Ashampoo Music Studio 6 software. The results showed that dangdut type 215 g was bigger than slow type 197 g. Average crowing duration dangdut type were 7,67 second, with longest syllable were 9 syllable and crowing duration slow type were 6,71 with longest syllable were 10 syllable.
