บทคัดย่อ (EN): The purpose of this study was to evaluate the effect of chopped urea-treated rice straw on nitrogen balance, fermentation and nutrient digestibility in dairy steers. Four rumen-fistulated dairy steers were randomly assigned according to a 2×2 factorial arrangement in a 4×4 Latin square design to receive four dietary treatments as follows:T1 = untreated long form rice straw (ULRS); T2 = 3% urea-treated long form rice straw (3% ULRS); T3 = untreated chopped (4 cm.) rice straw (UCRS); T4 = 3% urea-treated chopped (4 cm.) rice straw (3% UCRS). The steers were offered the concentrate at 0.5% BW and rice straw was fed ad libitum. The experiment lasted for 4 periods, and each lasted for 21 d. During the first 14 d feed intake measurement were made and during the last 7 d, they were moved to metabolism crates for total urine and fecal collection. The findings revealed significant improvements in dry matter intake (DMI) and digestibility of CP, NDF and ADF when steers fed with using 3% ULRS and 3% UCRS. Ruminal pH was significantly decreased (P<0.05) when 3% UCRS was supplemented, while NH3-N and BUN were found higher (P<0.05) as compared with urea-treated rice straw fed group. In addition, N intake, fecal N, urinary N and N absorption were increased by urea-treated rice straw group. Based on this study, implications could be made that using 3% urea-treated long form rice straw could increase rumen efficiency, N balance and digestibility in dairy steers.
