The massive meat production of broiler chickens make them continuously exposed to potential stressors that stimulate releasing stress-related hormones like corticosterone (CORT) which is responsible for specific pathways in biological mechanisms and physiological activities. Therefore, this research was conducted evaluate a wide range responses related performance, immune function, plasma biochemistry, gene expressions cell death morphology during after 7-day course CORT injection. A total...
A total of 450 broiler chicks (Ross 308) were used to evaluate the effect different inclusion levels a partially black soldier fly (BSF), BSF Powder (BSFP), Puré (BSFPr), and frozen whole larvae (BSFL) on growth performance, blood parameters, humoral immune response, intestinal bacterial count chickens. The chickens reared from day 1 35 assigned control 9 dietary groups with forms (3 replicates per group 15 chicks). Black was included at 2%, 4%, 6% for BSFP, BSFPr, BSFL, respectively, in...
One hundred and eighty Isa Brown layers, 40 weeks old, were used to study the role of dietary yeast supplementation on productive performance cholesterol levels in laying hens. All hens equally classified into four groups. The 1st group, fed basal diet without any (control), while those 2nd, 3rd 4th groups supplemented with at 0.2, 0.4, 0.6%, respectively. Feed consumption, feed conversion, egg production eggshell traits, serum total lipids, cholesterol, triglycerides concentrations as well...
addition of lactobacillus acidophilus in drinking water a concentration 10 8 cfu/ml.The third group (G3) treated with the thyme oil 1 ml/ liter.The fourth (G4) both and cfu/ml plus 1ml/L, respectively.The obtained results showed that, all treatments had significant improvement effects on measured parameters (performance characteristics, cecum RBCs, WBCs, kidney function, triglycerides, total cholesterol, sheep RBC's titer, liver antioxidant markers hormones markers) when compared to control...
This study was conducted to evaluate the effects of replacing soybean meal (SBM) protein with canola (CM) on productive performance, nutrient digestibility, immune response, lymphoid organs, blood parameters, carcass fatty acids and cecum microbiota broilers. A total 160 one d-old Arbor Acres broiler chicks were randomly allocated 4 dietary treatments 5 replicates, where, CM replaced SBM at 0, 30, 60, 90% for a 39 days feeding trial. The results showed no significant differences in...
The current study was conducted to investigate the influence of thermal manipulation (TM) during embryogenesis on hatchability traits, secondary sex ratio and hatchling weights broiler chicks. A total 1200 fertile eggs obtained from Cobb-500 breeder broilers parent stock were used in this study. randomly distributed into 4 experimental groups. Incubation conditions day 1 18 37.5°C 52% relative humidity for control group (TM0). while incubation temperature thermally treated groups 13-15 days...
Canola meal (CM) is used in all types of poultry feeds, however, because its relatively low energy; use high energy broiler diets restricted.No study has been conducted to evaluate the nutritional composition CM derived from an Egyptian variety (Serw 4) grown Egypt for diets.The present focused on evaluation (ECM) compared with soybean (SBM).ECM contained lower crude protein (35.98 vs. 50.92%);more ether extract (EE) (10.35 1.69%), fiber (12.58 3.60), calcium (0.53 0.32%) and total...
A total number of 990 embryonated (fertile) chicken (Arbor Acers) eggs were used in this study.The present experiment was conducted to evaluate the influence early inoculation Marek's disease virus and Reo during late embryonic development on Hatchability, chicks degree productive performance broiler chicks.The obtained from a commercial Parent stock farm (Cairo Poultry Company, CPC) at 53 weeks age.The parent hens specific Pathogen free (SPF) for common diseases.All weighted before setting...
A total number of 500 two weeks old sexed chicks from each strain (Inshas and Matrouh) were used to study the effects early heat stress on productive performance some physiological immunological traits.The divided randomly into five equal experimental groups (100 for group, 50 male female chicks).The first group didn't received any treatment served as control, The second was exposed (6 age) without anti -stress, third same with fourth both late (12 exposure, anti-stress, last anti-stress.The...
