The purpose of this study was to determine whether a vitamin B6 deficiency affects the utilization of 2-hydroxy-4-(methylthio) butanoic acid (HMB), an analogue of methionine. The basal diet used for this purpose was based on peas, peanut meal, and glucose monohydrate and was low in both methionine and pyridoxine. Supplemental pyridoxine hydrochloride and L-methionine or HMB resulted in significant increases in growth rate and efficiency of feed utilization; supplemental pyridoxine also produced significant increases in the activity of glutamic-oxaloacetic transaminase (PGOT, EC 2.6.1.1.) in plasma. There was no discernible effect of change in vitamin B6 status on the utilization of HMB as compared with L-methionine.
本研究的目的是确定维生素B6缺乏是否会影响蛋氨酸类似物2-羟基-4-(甲硫基)丁酸(HMB)的利用。为此所用的基础日粮以豌豆、花生粕和一水葡萄糖为基础,蛋氨酸和吡哆醇含量均较低。补充盐酸吡哆醇和L-蛋氨酸或HMB可显著提高生长速度和饲料利用效率;补充吡哆醇还可显著提高血浆中谷草转氨酶(PGOT,EC 2.6.1.1.)的活性。与L-蛋氨酸相比,维生素B6状态的变化对HMB的利用没有明显影响。
