Efek Rebusan Tanaman Serai (Cymbopogon citratus) dan Kecombrang (Etlingera elatior) terhadap Persentase Mortalitas, Nilai Ekonomis Pakan dan Nilai IOFC Ayam Broiler

Abstract

Giving phytobiotics to livestock is done to optimise the mechanism of action of active substances contained in herbal plants as antibacterials to overcome the use of antibiotics both in feed and drinking water. This study aims to determine the benefits of giving boiled water of herbal plants including lemongrass and torch ginger plants as phytobiotics on the percentage of mortality, increasing the economic value of feed and the IOFC value of broiler. The research was conducted at the Animal Husbandry Study Program Cage, Faculty of Agriculture, Universitas Sumatera Utara from March to April 2023 using a complete randomised design (CRD) with 4 treatments and 5 replicates. The treatments consisted of P0 as control, P1 (drinking water with the addition of lemongrass plant decoction water 25% of the daily needs of livestock), P2 (drinking water with the addition of torch ginger plant decoction water 25% of the daily needs of livestock), and P3 (drinking water with the addition of combined lemongrass and torch ginger plant decoction water 25% of the daily needs of livestock). The parameters observed were the percentage of mortality, economic value of feed and IOFC value of broiler. The results showed that the provision of lemongrass and torch ginger decoction water did not affect the percentage of mortality by 1%, the economic value of feed by Rp 15,735 and the IOFC value of broiler chickens by Rp 10,352.
