Studies on the Quality of Silage from Domestic Herbage II. Comparative experiment of feeding value of Arundinella hirta silage on additives.

야초 사일리지의 품질향상에 관한 연구 II. 안고초 사일리지의 첨가제에 따른 사료가치의 비교

An experiment was conducted to determine the feeding value of Arundinella hirat silage making by different methods ie., added starch 3%, formic acid 1% (FA), anhydrous ammonia ($NH_3$) 3%, and dried poultry waste (DPW) 3%. The samples were analyzed organic acid, cell wall constituent (NDF), cell contents (NDS), lignincutin-silica (ADL), hemicellulose (H: CHO) and in vitro dry matter digestibility (DMD) by pepsin-cellulase technique. The feeding value of silages were compared with corn siiage. The results are summarized as follows; 1.Formic acid treated to silage was lower pH(4.0), but anhydrous ammonia (8.37) and DPW added silage (8.72) were higher than that of the other treatment silages. 2.Fermentative quality of corn silage, starch, DPW, $NH_3$, control and FA treated silage were marked 100,81, 77,63,62 and 58, respectively. 3.Silage with $NH_3$, (23.57%) and DPW (10.42%) of content of protein were higher than that of other treated silages. 4.Silage with $NH_3$, was significantly lower contents of NDF, but did not ADF of among the treated silages. 5.In the contents of ADL, starch added silage was significantly decreased (p < 0.05), but did not the other treatment. 6.DMD of in vitro by pepsin-cellulase of silage with starch was increased three folds as equal to corn silage but did not increased the other treated silages. 7.Correlationship of latic acid an total acid, and NDS were a positive but lactic acid and NDF was a negative correlation.
