Given the numerous studies on in ovo injection of regulatory peptides including leptin, ghrelin, and peptidic hormones, is there a need to prepare a review article in this area, to determine whether these studies have reached a practical purpose? Is this hormone supplement helpful or not , in embryonic life or post-hatch life ? - is this useful in commercial term (commercial poultry production) ? there is a need to write a review in this subject.
