growth rate

Similar effects were observed for feed conversion ratio (FCR); higher levels of Na resulted in improvements at 7 day with no lingering effect at 14 day and 35 day of age. It can be concluded that feeding higher than normal Na level in diets fed from 0 to 7 day of age may result in increase in BW and feed conversion but this effect does not persist to 35 day.

怎么翻译比较合适？

对于饲料转化率也表现出类似的作用。提高钠的添加量，7日龄的饲料转率得到改善，但改善作用没有持续到14和35日龄。由此可以得出，0－7日龄的日粮中添加高于正常水平的钠可以增加体重和改善饲料转化，但是这种作用不会持续到35日龄。
