Ketarras chicken is a chicken produced from efforts to improve genetic quality through a crossing process with a genetic composition of 25% brown laying breed chickens and 75% Arabian chickens. One of the factors that influence the performance of laying hens during the layer period is maintenance during the starter period. To support this productivity, quality feed is needed. Feed has an important role, because it consumes around 60-80% of total production costs. Providing alternative feed ingredients that can meet the nutritional needs of livestock needs to be sought to obtain maximum profits. One alternative feed ingredient that is quite high in protein is maggot. This study aims to evaluate the effect of using maggot flour in rations on the performance of Ketarras chickens aged 0-6 weeks. The design used was a Completely Randomized Design (CRD) with 4 treatments with 5 replications and each replication used 8 Ketarras chickens. The differentiating factor used was the level of maggot flour, namely P0 (Control treatment), P1 (Use of maggot flour in ration 4%), P2 (Use of maggot flour in ration 8%) and P3 (Use of maggot flour in ration 12%). The variables observed were ration consumption, body weight, body weight gain and ration conversion. The results showed that ration consumption, body weight, body weight gain and ration conversion had no significant effect (P>0.05). Based on the research results, it can be concluded that maggot flour can be used up to a level of 12% without reducing the growth performance of Ketarras chickens aged 0-6 weeks.

Key words: Ketarras Chicken, Growth Performance, Maggot.
