Production performance of KUB chicken with the inclusion of Lamtoro (Leucaena leucocephala) leaf flour in the feed

Abstract

Abstract To reduce the feed cost in raising chickens it is necessary to find alternative feed sources. The feed ingredients must have relatively low prices, do not compete with human needs, and have abundant availability on location. The purpose of this study was to determine the performance of KUB chicken production with feed containing Lamtoro (Leucaena leucocephala) leaf flour (LLF). The study was conducted using 300 chickens aged 4 weeks, unsexed, which were allotted to 4 treatments, each with 5 replicates and 15 birds per replicate in a Completely Randomized Design. The treatments were in the form of a) T0: 0% LLF; b) T1: 3% LLF; c) T2: 5% LLF and d) T3: 7% LLF. The LLF was mixed with a basal feed in a mixture of concentrate, corn and bran. The study lasted for 6 weeks, i.e. until the chicken was 10 weeks old, with observations including daily weight gain (DWG), feed consumption, feed conversion ratio (FCR), and income over feed cost (IOFC). The results showed that the best performance of KUB chicken production was by the addition of 5% LLF in the feed, as it could increase the DWG value, reduce the FCR value and increase the IOFC value.
