Abstract
The productivity of Joper chickens can be increased by improving feed quality using fermented soy milk waste (SMW). This research was carried out through biological research using 100 day old chicks (DOC) Joper in healthy conditions using a completely randomized design (RAL). The research was carried out using 5 treatments of fermented SMW levels in feed (0, 5, 10, 15 and 20%) and each treatment used 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 was very significant (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). This research 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.
