Abstract

The productivity of Joper chickens can be increased by improving feed quality using fermented soy milk waste (SMW). This research was carried out using 100 day olds chick (DOC) Joper in healthy conditions using a completely randomized design (RAL). The 5 dietary treatments of fermented SMW at levels in feed (0, 5, 10, 15 and 20%) with each treatment consisting of 5 DOC Joper and was repeated 4 times. SMW in this study was fermented using effective microorganism 4 (EM-4) at a dose of 7.50% of the weight of SMW. Statistical analysis showed that the fermented SMW level significantly (p<0.01) increased feed intake, body weight gain and body weight of Joper chickens and reduced mortality and FCR. The average feed intake ranged from 2071.50-2207.00 g/head; body weight gain (14.71-25.55 g/bird/day); body weight (556.00-934.25 g/bird); mortality (0.84-1.25%) and FCR (2.34-3.75). It can be concluded that improving feed using fermented SMW can increase the productivity of Joper chickens. The best productivity of Joper chickens was using 15% SMW.
