Effect of crushing unhulled rice and the addition of fermented juice of epiphytic lactic acid bacteria on the fermentation quality of whole crop rice silage, and its digestibility and rumen fermentation status in sheep

Abstract

This experiment was carried out to examine the effect of crushing unhulled rice and the addition of fermented juice of epiphytic lactic acid bacteria (FJLB) on the fermentation quality of whole crop rice silage, and its digestibility and rumen fermentation in sheep. After whole rice plants ( Oryza sativa L. cv. Haenuki) were harvested between the yellow and fullripened period of maturity, and cut at a length of 2 cm, four silage treatments were set: (i) non-treatment; (ii) crushing treatment of unhulled rice division (crushing); (iii) addition of 1% FJLB; and (iv) crushing + addition of 1% FJLB. Lactic acid content increased with the addition of FJLB, and was highest in the crushing + FJLB treatment. Digestibilities of crude fiber, acid detergent fiber and neutral detergent fiber were significantly higher during the crushing + FJLB treatment. There were no differences among treatments in the volatile fatty acid concentrations before and after feeding. At 4 h after feeding, however, the ratio of acetic acid : propionic acid was significantly lower with the addition of FJLB. It was proven that the fermented quality of silage was improved when FJLB was added to rice plants and then ensilaged, and the digestibility of the fibrous component was raised when unhulled rice division was crushed and FJLB was supplemented.

Effects of applying molasses, lactic acid bacteria and propionic acid on fermentation quality, aerobic stability and in vitro gas production of total mixed ration silage prepared with oat–common vetch intercrop on the Tibetan Plateau

“…Buffering capacity was determined by the hydrochloric acid–sodium hydroxide method of Playne and McDonald . Ammonia‐N, lactic acid and volatile fatty acids were determined using the method of Shao et al To assess the quality of the silage, we calculated the V‐score from the NH 3 –N/Total N and VFAs concentrations . The mixed samples (10 g) were blended with 90 mL of sterilised water, and serially diluted in sterilised water.…”

Fermentation quality and nutritive value of green soybean stover silage

“…Butyric acid content (fresh weight basis) of added FJLB silage was substantially lower than that of non‐FJLB silage. Takahashi et al . (2005) reported that the lactic acid content increased and the fermentative characteristics tended to improve in whole crop rice silage with the addition of FJLB prepared from fresh rice straw.…”

“…Takahashi et al . (2005) reported that crude fiber and ADF digestibilities were improved by adding 1% FJLB prepared from fresh rice straw to the diet of sheep fed whole crop rice silage and commercial concentrate.…”

Effects of applying oil‐extracted microalgae on the fermentation quality, feed‐nutritive value and aerobic stability of ensiled sweet sorghum

“…using a five‐point scale as follows: 1 (very bad), 2 (bad), 3 (moderate), 4 (good) and 5 (very good). Moreover, we also evaluated the quality of the silage with the V‐score method, calculating from the NH 3 ‐N/TN and VFAs concentrations . Briefly, V ‐ score = Y N + Y A + Y B , where Y N is calculated from the ratio of NH 3 ‐N/TN (% TN), Y A is calculated from the acetate plus propionate contents (% DM), and Y B is calculated from the butyrate content (% DM).…”
