看來我們有同樣的執(zhí)著,我同意你的很多觀點,過瘤胃蛋白的不平衡是會提高內源尿素產量,這一點沒有懷疑,但我們需注意一個問題;到底這個差異有多少,這種差異和瘤胃可降解蛋白產生的氮相比有多大的比例,我們做一個
我說過不做解釋脲酶抑制劑,因為不關心其銷路。如果你懂英文,我截一段:
Urease inhibitors. Greater than 50% of ammonia in livestock slurries originates from urea hydrolysis (Van Horn et al., 1996). Thus, successfully nhibiting this process will potentially conserve nitrogen in waste. Studies have been conducted in the rumen to determine the effectiveness of various urease inhibitors (Ludden et al., 2000; Whitelaw et al., 1991; Jones and Mulligan, 1975). These results suggest that short-term inhibition in the rumen is possible, but the ruminal microflora appear to adapt to the inhibition and some of the inhibitors are absorbed by the rumen, which limit their practical use in improving utilization of dietary urea (Ludden et al., 2000; Whitelaw et al., 1991).
