AB The ruminal degradability of starch ("RDS") is an important indicator of utilization of starch by ruminal microorganism. Degradability rate influences the starch amount that will be utilized in rumen and the amount that will be digested in abomasum. The importance of those by-pass nutrients grows up with the increasing of dairy milk production.The aim of this experiment was to determinate the influence of the locality, hybrid, treatment against european corn borer ("ECB") and used silages additive on the ruminal degradability of starch in the maize silage.The experiment proceeded in three different localities. In each locality were grown on the parcels two groups of maize plants with regards to treatment against ECB (treated - experimental, untreated - control). Into each group were used three hybrids with the different number of FAO. At the harvest of silage maize was the chopped forage taken from each locality, group and hybrid apart and ensiled into experimental tubs. During conservation were prepared the silages without the addition of preparation, silages inoculated by the microbial preparation (amount 15g/l) and silages with the addition of the chemical agents (organic acids and salts blend 2l/t matter). The values of RDS were detected through the method "in sacco"(nylon bags).The significant difference (P < 0.01) between the values of RDS was detected between the silages from various localities. (Senice na Hané 56.06 ± 4.00%; Starojická Lhota 48.02 ± 4.83%; Záblatí 43.49 ± 2.73%). The treatment against ECB did not affect significantly (P
