IMPLEMENTATION ON DIET OF PROBIOTIC Saccharomyces spp.SB-6 ISOLATED FROM COLON OF BALI CATTLE ON EGG PRODUCTION AND EGG CHOLESTEROL CONCENTRATION OF LOHMANN BROWN LAYING HENS

Abstract: The current study was aimed to study the effect of addition on diet of various levels of probiotic Saccharomyces spp.SB-6, isolated from colon of Bali cattle, on egg productions and its total cholesterol levels of Lohmann Brown layers. A total number of 120 layers at 32 weeks of age and with homogenous body weight were randomly divided into 4 treatment groups. Each treatment group consisted of 6 replications and with 5 birds in each of it. Therefore, 24 battery colony pens were provided. The four treatment groups were assigned based on their diets, namely treatments B, C, and D in which their diets were supplemented with 0.20, 0.40, and 0.60 g of probiotic/kg of diet, respectively, whereas there was no probiotic supplementation for treatment A which was considered as the control group. All experimental birds were fed ad libitum. Six eggs from each treatment group were collected randomly for assessment of cholesterol content following standard procedure. The present results showed that, compared to control birds, layers that subjected to probiotic supplementation have a significant increase (P<0.05) in egg production (hen-day production) and in the total egg weight, but showed a slight decrease in serum and egg cholesterol contents. Thus, it may be concluded that addition on diet of probiotic Saccharomyces spp.SB-6 at various level has positive effects on chicken production and, therefore, it can be recommended widely to chicken farmers.
