The results showed that the body weight of the iglets at day age of 21 and 42 was im roved by 9. 64% and 12. 09% , the daily weight gain of the iglets at day age of 0~ 21, 21~ 42 and 0~ 42 w as increased res ectivel- ly by 11. 68% , 15. 06% and 13. 56% com aring with the control grou s after feeding the ration including lactic acid. However the numbers of diarrhoea w ere decreased greatly ( 2B12) , the feed conversion rate w as im roved by 13. 1% , and economic efficiency w as im roved by 16. 28% . So the effects of lactic acid for the iglets were better than those of the similar im orted roducts.
