The aim of this study was to investigate the effect of in ovo administration of ghrelin on
subsequent small intestine Sucrase activity in broilers. In this experiment 900 fertilized eggs
were collected from commercial breeder flock. The eggs were divided into five experimental
groups; control (without injection), group 2 (in ovo injected with basal solution), group 3 (in ovo
injected with 50 μg/egg ghrelin), group 4 (in ovo injected with 100 μg /egg ghrelin) and group 5
(in ovo injected with 150 μg /egg ghrelin). In ovo injection was done at day 7 of incubation.
Two broilers from each group have been choose and slaughtered on days 21 and 42 of rearing
period and 1, 10, 30, 50, 70 and 90 percent of small intestine sampled for evaluate Sucrase
enzyme activity. According to the results, in ovo injection of 100 μg /egg ghrelin increased
intestine Sucrase enzyme activity in different parts of small intestine on day 21 post hatch
(P<0.05) but had no effect on day 42 (P>0.05). These results suggest that in ovo injection of 100
μg ghrelin had beneficial effect.
