Abstract
(30) Male Awassi lambs was used in this experiment, Lambs was borne in abu-graib station , the age of these animals rang between (7-9) month, half of these animals are low body weight (dwarf) but the others animals are normal. The dwarf lambs was assigned randomly to five groups contain (3) animals, group one named (control) the other groups was injected with combination hormones like(growth+estradiol+cortisol),(growth+estradiol),(estradiol+cortisol) , growth+cortisol) for the group 2,3,4,5 respectively , the normal animals was assigned randomly to 5 groups and treated like the dwarf animals. The animals feed concentrated 2% of body weight and feed hay and the experiment continue 70 day.The experiment showed that the dwarf animals have very low in weight it ranged between(19.7-26.7) and have very low in concentration in growth hormone its ranged between (0.17-0.20) ng/ml and have very low in estradiol hormone (9.0-9.57) ng/ml and in cortisol hormone (3.6-4.37)ng/ml.but whene the injection of these animal with combination of hormones lead to great increased in daily gain such as (237.2)g/day,(247.9)g/day and (239.0)g/day in group 2,3,4 respectively compare to daily gain of control group (175.2)g/day we obtain amore little daily gain in group 5 (growth cortisol) probably due to the reflex between growth hormone and cortisol hormone about the pituitary gland, the injection of combination hormones was not effect significant but different group of normal animal but the group 5 show significant little daily gain (145.3)g/day and the resume was disclosed above.
