The dynamics of population and production of Native Chicken under extensive- and semi-intensive maintenance

Abstract

This study evaluated kampung chickens’ growth rate and production performance in extensive and semi-intensive rearing in Central Java, Indonesia. The survey method was employed for this study. The targets used in the study were kampung chicken farmers in the Banyumas and Kebumen areas. The survey method is carried out by collecting data, observing and measuring population, production performance, including meat and egg production. The data obtained, processed, and presented in the tables and graphs, calculated the population and production of chicken to evaluate its growth. The performance of chicken production, including egg production, egg weight, number of eggs hatched, and hatchability, was analyzed using general linear model (GLM) analysis. The result showed a 1.9% growth rate of the native chicken population, in which the hens outnumbered the roosters. The meat and egg production growth rates were 8.2% and 6.8%, respectively, between 2016 and 2020 in Central Java. Native chickens kept under semi-intensive maintenance produced more eggs than those in an extensive system. Conclusively, native chicken of Central Java experienced growth in population and production of meat and egg. The semi-intensive system, compared to the extensive system, had a higher rate of eggs production.
