The need of people’s animal protein increases every year. One of the alternative sources of animal protein that can be easily obtained is Jowo Super chicken (Gallus domesticus), a hybrid resulting from Kampong chicken and laying hens. However, the high cost of the chicken food causes hardships for breeders in the process of achieving production efficiency whereas it contributes 60%-70% of the whole production cost. One of the ways that can be used and be the solution in the effort to suppress the food and production cost is by applying the Integrated System of Crops – Livestock – Fish. This research has the purpose to find the effect on the feed variation on Jowo Super chicken (Gallus domesticus) based on the treatments towards each food variation. This research was done in Biological Physics Laboratory of Faculty of Agricultural Technology Universitas Gadjah Mada. The livestock used in this research are 32 Jowo Super chicken (Gallus domesticus) aged 3 weeks at the start of the research and 8 weeks at the end of the research. The chickens were placed inside 4 cages with each containing 8 chickens as replications. This research used Completely Randomized Design (CRD) with 4 treatments and 8 replications. The variations of chicken foods are i) 100% commercial food, ii) 50% commercial foods, 30% BSF maggot (Hermetia illucens), 20% mustard waste (Brassica rapa L), iii) 50% BSF maggot (Hermetia illucens), 30% commercial food, 20% mustard waste (Brassica rapa L), iv) 100% BSF maggot (Hermetia illucens). The result of this research is that the P2 treatment has the most optimum level of growth efficiency in chickens |
