The Effect of Improved Juice Wastes Mixture (IJWM) for Corn Substitution on Broilers’ Performance

Abstract

2 Abstract: The Juice Wastes Mixture (JWM) is a combination of waste from carrot and some fruits (apple, mango, avocado, orange, melon and tree tomato) in the same proportion after their juices were squeezed for fresh drink. The JWM could be as an alternative potential feed for replacing corn in the broiler diet. The problem of JWM as broiler feed is the high in crude fiber and low in metabolic energy contents. After processing the JWM by soaking in 20% concentration of rice hull ash filtrate for 72 hr (IJWM), its crude fiber decreased, while its metabolizable energy increased. An experiment was conducted to evaluate the utilization of IJWM in broiler diets. The experiment was performed in a completely randomized design with different levels of IJWM (0, 20, 25, 30, 35 and 40%) for replacing corn in the broiler diets. The variables measured were feed consumption, average daily gain, feed conversion, live body weight, abdominal fat pad percentage, carcass percentage, liver percentage and pancreas percentage. Every treatment was repeated 4 times. The results showed that the IJWM influenced the feed consumption, average daily gain, live body weight, feed conversion and abdominal fat pad very significantly (P<0.01). Meanwhile, liver percentage and pancreas percentage were not affected by the IJWM. In conclusion, the IJWM could be included up to 40% to effectively replace 80% corn in the broiler diets.
