Effect of Feeding a Combination of Fish Waste and Indigofera zollingeriana Leaves as Diet for Laying Quails (Coturnix coturnix japonica): Impact on Production Performance

The study aims to determine the possibility of using fish waste substituted with soybean flour as one of the raw materials for making fish feed on the physical quality of fish feed.The research design used a completely randomized design with 3 treatments of comparison of the use of fish waste substituted with soybean flour; each treatment A was 40% fish flour and 20% soybean flour.Treatment B had 42% fish waste flour and 18% soybean flour, Treatment C had 44% fish waste flour and 16% soybean flour, while Treatment K had 100% fish waste flour.The results of the study showed that in terms of the physical quality of fish feed, in general the feed meets the requirements of fish feed, especially in terms of the attractiveness of the feed and the color of the feed, but in terms of the solubility and hardness of the feed, the fish feed produced is classified as high so that its solubility is also low.Therefore, it is recommended for the manufacture of further feed to reduce the amount of feed adhesive Keywords: Fish waste, soybean flour, fish feed, physical quality, feed solubility
