Abstract

Jawa super native chickens are the result of a cross between native chickens and laying hens. Super native chickens have the advantage of greater body weight and faster growth. Citronella is one of the grass plants that contains saponins, flavonoids, and polyphenols that have antiseptic properties for the digestive tract of chickens and increase feed palatability. This study aims to provide information to the public to assess the effect of using citronella flour on the growth of commercial weight of super native chickens. This research was conducted on July 26 - September 26, 2023, at Padasuka Village, Ciomas, Bogor. This study used a completely randomized design (CRD) with 5 treatments and 4 replicates with a total of 100 DOC. Data were analyzed using analysis of variance (ANOVA) and Duncan's further test. R0 = Control ration, R1 = addition of 2% citronella meal in ration, R2 = addition of 4% citronella meal in ration, R3 = addition of 6% citronella meal in ration, R4 = addition of 8% citronella meal in ration. The variables observed in this study were the percentage of breast and thigh, the percentage boneless of breast and thigh, the percentage bone of breast and thigh, the percentage skin of breast and thigh, and the ratio of bone and meat breast and thigh. The result of this research is that the provision of citronella flour at a concentration level between 2 to 8% has not shown a significant effect on the percentage of meat and bone on the breast and thigh, the percentage of bone on the breast and thigh, the percentage of skin on the breast and thigh, and the ratio of meat and bone on the breast and thigh in joper native chickens. However, citronella meal had a tendency to increase the boneless percentage in free-range chickens with a concentration of 6%.

Abstract

Merawang chicken is a dual–purpose type of chicken whose egg and meat production is relatively high. The use of fish meal in chicken feed plays a role in the formation of chicken meat, but the high price and availability of feed are obstacles in rearing. The use of Black Soldier Fly (BSF) maggots can be an alternative feed to replace fish meal because it has a protein content of around 60%. The aim of this research was to test the effect of giving maggot meal as a substitute for fish meal in the ration on the percentage of boneless meat in merawang chickens. This research was conduced at Papidoka Farm (Caringin, Bogor) from October 2023 to November 2023. The study used 60 merawang chickens on 9 weekold with an average body weight ranging from 721.8 ± 68.6 g/bird. The research design used was a Completely Randomized Design (CRD) with 5 treatments and 4 replications, and the test results were analyzed using IBM SPSS for ANOVA and Duncan's advanced test. The treatment given in the ration is P0 = 0% maggot meal + 10% fish meal, P1 = 2.5% maggot meal + 7.5% fish meal, P2 = 5% maggot meal + 5% fish meal, P3 = 7, 5% maggot meal + 2.5% fish meal, P4 = 10% maggot meal + 0% fish meal. The variables observed were the percentage of meat, the percentage of boneless meat, the percentage of bone, and the percentage of skin on the breast and thighs of the merawang chicken. The results of the analysis of variance showed that giving maggot meal as a substitute for fish meal at a level of 0 – 10% in the ration of merawang chickens had a significant effect (P<0.05) on breast percentage, boneless meat percentage, breastbone percentage, breast skin percentage, thigh percentage, thighless meat percentage, thighbone percentage, thigh skin percentage and meat bone ratio (MBR) of chicken breasts and thighs. The conclusion of this research is that giving maggot meal as a substitute for fish meal at a level of 5% maggot meal and 5% fish meal can increase the percentage of boneless breast and thigh meat.
