\normalsize{
The objective of this study were evaluate ruminal degradability of napier Pakchong 1 silage supplemented with lactic acid bacteria. Lactic acid bacteria (LAB) were extracted from corn silage with 1\,$\times$\,\unitfrac[105]{cfu}{ml} concentration to spread  in MRS agar plate at 37 degree celsius for 48 hours in anaerobic condition. This research was conducted by completed randomised design (CRD) and compare the difference in average by least significant difference (LSD). Silage were divided 2 groups (control and supplemented with LAB). LAB was spplemented with napier Pakchong 1 grass as 10 ml:\mbox{1\,kg}. Silage was collected at the day of 14, 21, 28 and 35 days of fermentation. Three fistulated Thai native cattles (White Lamphun cattles) with average weight 154$\pm$\mbox{4.69\,kg} were used for the ruminal digestibility analysis by nylon bag technique. Dry sample with 2--5 mm. were weighed into nylon bag then incubated in the rumen at  8, 12, 24, 48, 72 and 96 hrs. Ruminal degradability parameter were analysed  by NEWAY program. It was found that \%dry matter disappearance at 12, 24 hours of 21 days fermented napier Pakchong 1 silage was highest\mbox{.\,\%} DM disappearance at 8--72 hours of napier Pakchong 1 silage supplemented with LAB were not significantly different from control group but \% DM disappearance at 96 hours of napier Pakchong 1 silage supplemented with LAB were higher than control group. Eventhough the ruminal degradability parameter including soluble fraction (A) insoluble but fermentable fraction (b) and rate of degradability (c)  and potential degradability (P) were not affected by LAB supplementation but the effective degradability at (at out flow rate = 0.08) of silage supplemented with LAB were higher than control group. It can be concluded that LAB supplementation increase ruminal degradability of napier Pakchong silage}
