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.

怎么翻譯比較合適？

對于飼料轉(zhuǎn)化率也表現(xiàn)出類似的作用。提高鈉的添加量，7日齡的飼料轉(zhuǎn)率得到改善，但改善作用沒有持續(xù)到14和35日齡。由此可以得出，0－7日齡的日糧中添加高于正常水平的鈉可以增加體重和改善飼料轉(zhuǎn)化，但是這種作用不會持續(xù)到35日齡。
