Pemberian Konsentrat dan Limbah Pasar (Kangkung, Kubis dan Daun Singkong) terhadap Performans Ternak Jangkrik Kalung (Gryllus bimaculatus)

Abstract

In Indonesia, crickets (Gryllus sp.) are used as food for pets, especially insectivorous animals, one of which is necklace crickets. Necklace crickets have a short life cycle, high egg hatchability, fast growth and low feed conversion, and have a softer body skin so they are preferred by birds and other insectivorous animals. Feed is very important in intensive maintenance of crickets, especially in cricket hatchery. The feed given to crickets is generally in the form of concentrate and leaves. This study aims to determine the effect of concentrate and market waste (kangkung, cabbage, cassava leaves) on the performance of necklace crickets (Gryllus bimaculatus). This research was conducted at the Livestock Biology Laboratory, Animal Husbandry Study Program, Faculty of Agriculture, from March to April 2020. This research was conducted experimentally using a Completely Randomized Design (CRD) consisting of 4 treatments and 5 replications. The treatments consisted of P0 = 100% market waste, P1 = 75% market waste + 25% concentrate, P2 = 50% market waste + 50% concentrate, P3 = 25% market waste + 75% concentrate. The variables of this study were broodstock mortality, feed consumption, body weight gain, and feed conversion. The results of this study showed that the administration of concentrate and market waste (kangkung, cabbage, and cassava leaves) did not significantly affect the performance of necklace crickets. The average mortality in this study was 6.4%, the feed consumption value was 8.74 g/head/day, the average body weight gain was 0.43 g/head/day, and the average feed conversion was 20.71 g/head.
