UTILIZATION OF PROBIOTIC KHAMIR (Saccharomyces spp.) TO IMPROVE THE EFFICIENCY OF USE OF THE RANSUM AND THE QUALITY OF CHICKEN EGGS

The most important thing in the business of laying hens is to increase the efficiency of ration use. The efficiency of ration use can be measured from the value of Feed conversion ratio (FCR), which is the ratio between the amount of ration consumed with the weight of eggs produced in the same time unit. The lower the FCR value, means the higher the efficiency of ration usage, and vice versa. Laying chicken rations nearly 90% use plant-based feed, of which around 40-50% of the cell components are composed of cellulose and hemicellulose fractions which are very difficult to digest by the digestive enzymes of poultry. In order to be hydrolyzed, the crude fiber fraction must first be broken down into low molecular weight compounds, such as mono, di, and tri saccharides. This degradation involves a complex of cellulase enzymes produced by yeast, endo-beta-glucanase and beta glucosidase. Therefore, this study aims to utilize the yeast Saccharomyces spp contained in the "tape" yeast in laying hens using high rice bran to the production and physical quality of Lohmann Brown chicken eggs aged 70-80 weeks, viewed from the aspect of increased performance and efficiency egg production, and the physical quality of eggs. The output of this research will produce a package of formula formulation based on rice bran containing perobiotics (feed supplement products, TKT-3), and international publications.
