Expression of hepatic IGF-I, IGF-II and IGF-I receptor genes in Ross broiler
chickens fed thyme (Zataria multiflora) extract and probiotic.
Onl J Vet Res., 21(9):584-590, 2017. Effect of thyme extract and probiotic (Broilact) supplement on expression of liver Insulin like
growth factor- 1 (IGF- I), insulin like growth factor- 2 (IGF- II) and IGF- I receptors
gene expression are described. 36 Ross male broilers (r=3 & n=12) were used
per treatment consisting of a basic corn-soybean control diet supplemented with
thyme or probiotic for 42 days. The results of this study showed that by 42
days, thyme extract had had no effect on expression of liver IGF-I, IGF-II and
IGF-I receptor genes (P>0.05). Also, probiotic had had no effect on
expression of liver IGF-I, IGF-II (P>0.05). Expression of liver IGF- I and
IGF- II gene did not change under any diet compared with controls (P>0.05). However
liver IGF-I receptor gene expression in those supplemented probiotic increased
compared with controls or those given thyme (P<0.05).
