Abstract

We examined the effect of the licorice on the IGF-1, GH and growth performance of Japanese black Calf. Five calves fed the licorice about 20 days, and other five calves was no fed the licorice at change of raising environment (single raise to group raise). The GH, IGF-1 and growth performance were determined before and after of fed test. The licorice was fed at once per day with concentration. The result of effect of licorice fed showed that GH concentration was higher in fed of licorice group than non-fed of licorice group (p < 0.05), IGF-1 concentration was tend to higher by fed of licorice, and growth performance was no significant difference in each groups. In daily gain, we confirmed that group of fed–licorice was stability changed, but group of non-fed-licorice was unstability changed. These results suggested that GH and IGF-1 level was improved at change of raising environment by fed of licorice.
