The effect of soybean meal substitution with Indigofera zollingeriana and addition of turmeric as phythobiotic on performance of native chicken

The feed well is that protein content is high enough to meet the needs and improve endurance of chickens. This research aims to determine the effect of giving Indigofera zollingeriana with a combination of turmeric flour at different treatment levels in substituting soybean meal usage on performance, protein and fiber consumption of chicken grower phase. This research was conducted from July to September 2020 at the Poultry Production Laboratory, Faculty of Animal Science, Hasanuddin University, Makassar. Using 80 grower phase native chickens. The research design used was a completely randomized design (CRD) with 4 treatments and 5 replications R0 (control feed), R1 (basal feed + 10% flour Indigofera zollingeriana + 2.5% turmeric flour), R2 (basal feed + 15% flour Indigofera zollingeriana + 2.5% turmeric flour), R3 (basal feed + 20% flour Indigofera zollingeriana + 2.5% turmeric flour). Data using analysis analysis of variant (ANOVA) with Response Test. The results of this research showed a significant effect (P < 0.05) on feed consumption, body weight gain, crude fiber consumption and crude protein consumption and showed not significant differences (P > 0.05) in feed conversion ratio. The mean of feed consumption was 297.89-421.13 g/day. The mean of body weight gain was 88.43- 187.18 g/ bird. The mean of feed conversion is 2.65-4.46. The mean of consumption of crude protein was 15.26-23.70 g/bird/day. The mean of consumption of crude fiber is 2.30-4.21 g/bird/day. This research concluded that the R1 treatment (basal feed + 10% flour Indigofera zollingeriana + 2.5% turmeric flour) was the most efficient in optimizing performance, consumption of crude protein and crude fiber in the treated feed.
