Ghrelin is a regulatory peptide with specific anti-oxidative effects. The aim of this study was to investigate the activity of two antioxidant enzymes includes superoxide dismutase (SOD) and glutathione peroxidase (GPx) in erythrocyte of newly-hatched chicken following in ovo administration of ghrelin. The fertilized eggs were divided into four experimental groups; control G1 (without injection...

The ovo and ovarian tumor genes are required during early and late stages of Drosophila oogenesis. The ovo product, a zinc-finger transcription factor, can bind to sites and influence the level of expression of the ovarian tumor promoter. Our examination of ovo null mutant organelles demonstrate that it is required for the differentiation of XX germ cells during larval gonial stages, in additio...

The feasibility of establishing probiotic bacteria in the intestine of broiler chickens by in ovo inoculation was investigated, followed by verifying possible subsequent protection against Salmonella Enteriditis infection. In a first study, 7 commercially available probiotics were screened for compatibility with in ovo inoculation. Two of these probiotics, one being a Enterococcus faecium and t...

The Drosophila melanogaster ovo gene is required for survival and differentiation of female germline cells, apparently playing a role in germline sex determination. We recovered 60 kb of genomic DNA from its genetic location at 4E1,2 on the X chromosome. A transcription unit coding for an apparently female-specific germline-dependent 5-kb poly(A)+ RNA size class is located substantially in a 7-...

Maintenance of glucose homeostasis during late-term embryonic development is dependent upon the amount of glucose held in reserve primarily in the form of glycogen in the liver and upon the degree of glucose generated by gluconeogenesis from protein first mobilized from amnion albumen and then from muscle. Insufficient glycogen and albumen will force the embryo to mobilize more muscle protein t...

This study was conducted to investigate the effect of in ovo feeding (IOF) of folic acid on the folate metabolism, immune function and the involved epigenetic modification of broilers. A total of 400 (Cobb) hatching eggs were randomly divided into four groups (0, 50, 100 and 150 µg injection of folic acid at embryonic age 11 d), and chicks hatched from each treatment were randomly divided into ...

The aim of this study was to investigation on effects of in ovo administration of ghrelin on leukocytes count and heterophil/ lymphocyte (H/L) ratio in hatched chicks. 250 fertile eggs were divided to 5 groups; control or group 1 (without injection), group 2 (in ovo injected with 50 ng ghrelin at day 5), group 3 (in ovo injected with 100 ng ghrelin at day 5), group 4 (in ovo injected with 50 ng...
