Abstract
This study was conducted to 1) determine the effect local of probiotic supplements on shell thickness, weight loss persentage, and Haugh unit of eggs which stored ten days; 2) determine the optimal level of supplements local of probiotic on shell thickness, weight loss presentage, and Haugh unit of eggs which stored ten days. This research was held on 08--19 December 2014 in the CV. Varia Agung Jaya henhouse laying in the District of Seputih Mataram, Center of Lampung Regency and continued on 20 December 2014--18 January 2015 in the Laboratory of Microbiology, Laboratory of Molecular Biology Faculty, University of Lampung. The study used completely randomized design (CRD) with 4 treatments of local probiotics in the diet (0%, 1%, 2%, and 3%) and 5 replications. Data obtained was analyzed using analysis of variance at 5% level and continued Orthogonal Polynomial test at 5% level. Based on these results we can conclude: effect of local probiotics in the diet (0,1,2, and 3%) no significant
(P> 0.05) on the weight loss presentage and Haugh unit of eggs which stored ten days, but significant
(P <0.05) on shell thickness. Increasing the percentage of local probiotic on the ration will improve shell thickness indicated by the regression equation ŷ = 0.42 + 0,24x, with r = 0.68 and R2 = 0.47.
