Utilization of golden apple snail egg as feed additive in laying hen

open access: yesIOP Conference Series: Earth and Environmental Science
Abstract Naturally bioresources play an important role as bio-additive sources in animal production. The eggs of golden apple snails could be a source of carotenoid, particularly astaxanthin. The goal of this experiment was to assess the impact of the eggs of golden apple snails on the growth performance of laying chickens.
