| 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... |

| 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... |

| ABSTRACT A feeding trial was conducted to determine the potential value of replacing 100 % of meat and bone meal (MBM) ingredient as the major animal protein source in Japanese quail diets by 50% and 100% of insect meal derived from S. littoralis Larvae. A total of 360, 7 days-old quail chicks, were randomly divided into three equal groups (120 chicks) with three replicates each. They were offered three different diets 1, 2 and 3, respectively. The Diet 1 contained MBM only as a major source of animal protein, diet 2 had both MBM (50%) and insect meal (50%) while diet 3 contained insect meal (100%). Results: Partial or total replacement of S. littoralis larvae with MBM increased body weight gain and improved feed conversion ratio (p≤0.05). Moreover,... |
