The effects of probiotic on leptin level, body, liver and abdominal fat weights during the rapid growth phase of broilers

Abstract

The importance of of probiotic feeding in broiler nutrition has been shown in recent studies. Probiotics increase the yield by decreasing health problems and increase feed efficiency ratio (Dilwort and Day, 1978), live-weight gain (Zulkifi et al., 2000) and the, amount of, abdominal fat in broilers (Burkett et al., 1971).
