Efficacy of Zinc/Creatine Supplementation on Improving Growth Performance of Local Balady Chicks Rev. Bras. Ciênc. Avic.
Amer,NSI; Hatab,MH; Sabic,EM.
ABSTRACT An experiment was designed to study the efficacy of Zinc and or creatine monohydrate (CMH) supplementation, either alone or in combination, on improving growth performance of Balady chicks. A total number of 144 Balady chicks were randomly divided into four equal groups. The first treatment was fed the basal diet and served as control, while groups 2, 3, and 4 were given the basal diet and supplemented drinking water with, 0.6 mg/ml (zinc sulphat); 0.45 mg/ml (CMH); 0.6 mg/ml (zinc sulphat) + 0.45 mg/ml (CMH), respectively. The results indicated that the live body weight, weekly body weight gain and feed efficiency were significantly (p≤0.05) improved in all treated groups compared with the control. Also, significant decrease (p≤0.05) has been...

Oxidative Stress of in-Ovo Ochratoxin A Administered during Chick Embryonic Development Rev. Bras. Ciênc. Avic.
Elsayed,MAE; Mohamed,NE; Hatab,MH; Elaroussi,MA.
ABSTRACT The present work was carried out to study the effect of in-ovo injection of ochratoxin A (OTA) as an oxidative stress and its consequences on hepatic and kidney functions, thyroid activity, and histological examination of brain and liver in chicken embryos and subsequently in the hatching chicks. On the 10th day of incubation, one hundred and sixty-two fertile eggs were randomly divided into two equal treatments. Control treatment, (injected by 50 µl sodium carbonate) and OTA treatment (injected by 12.5 ng OTA dissolved in 50 µl sodium carbonate). OTA treatement group significantly reduced glutathione (GSH) and significantly increased thiobarbituric acid reactive substances production (TBARS) in embryonic and hatched chicks regarding livers,...

Toxic Effects of Ochratoxin A on Calcium Metabolism during Chick Embryo Developmentand in Hatched Chicks Rev. Bras. Ciênc. Avic.
Elsayed,MAE; Hatab,MH; Elaroussi,MA.
ABSTRACT The present study was carried out to study the effect of in-ovo ochratoxin A (OTA) injection in Highline layer eggs on calcium metabolism and blood biochemical parameters of embryos and after the hatch. At day 10 of embryonic development, one hundred and sixty-two fertile eggs were individually weighed and divided into two equal treatments. The first treatment (control) consisted of the individual injection of fertile eggs with 50 µL sodium carbonate. In the second treatment (OTA), fertile eggs were individually injected with 12.5 ng OTA dissolved in 50 µL sodium carbonate. On days 12, 14, and 16 of incubation and at the hatch, serum calcium and inorganic phosphorus concentrations were lower (p<0.05), while sodium, alkaline phosphatase and...
