Abstract The short periods of incubation during egg storage (SPIDES) method enhances the quality chicks and improves hatching rates. Additionally, embryonic thermal conditioning (TC) is a technique used to enhance thermotolerance in birds. Previous studies have evaluated effects SPIDES TC separately. Yet, our hypothesis postulated that synergistic effect could be achieved by integrating SPIDES, thereby enhancing broilers' resilience stress. We conducted an experiment involving 800 Ross...

This study aimed to investigate the possibility of producing broiler meat rich in long-chain n-3 polyunsaturated fatty acids especially eicosapentaenoic acid (EPA, C20:5 n-3) and docosahexaenoic (DHA, C22:6 with preventing lipid oxidation produced by supplementing diets linseed oil or fish along vitamin E (Vit. E) sweet chestnut tannins (SCT) as antioxidants. A total 144 1-day-old Cobb chicks were divided into six treatments three replicates, eight each. The basal containing 2 g oil/100...

There are few data about early thermal conditioning (TC) and its effect on later life in rabbits. Therefore, the present study aimed to investigate impact of exposing two rabbit breeds age short-term heat stress (EA-STHS) physiological parameters hepatic expression levels some genes. Rabbits from New Zealand White (NZW) Baladi Black (BB) were reared a controlled environmental chamber (28 ± 2 °C 40 2% RH). At 42 days age, rabbits both equally divided into groups; control (untreated) exposed...

Delivering natural antioxidants via in ovo feeding holds promise for enhancing the antioxidant status and performance of chickens. Therefore, The objective this study was to evaluate impacts during early embryonic development using grape pomace extract as a on hatchability, productive performance, immune response, broilers. A total 900 fertile broiler eggs from Arbor Acres strain were utilized. Each egg individually weighed, with weights ranging 61.88 ± 3 g. On 17.5th d incubation (DOI),...

The objective of this study was to investigate the beneficial effects early age thermal conditioning and lighting regime reduc adverse hot weather condition, especially on oxidative stress immune function Muscovy ducks. Experimental design a 2 × (4 groups 160 ducks) during summer season. Ducks were divided into two equal groups. control group, maintained under normal ambient temperature, second group exposed (exposed temperature 39±1°C for 6 h at 5th day then subjected temperature.

Abstract Background The etiology of autism has emerged as a topic serious debate in recent years, where autoantibodies may play role. IL-17A is key regulator Autism spectrum disorder development, while interleukin (IL)-22 potent mediator inflammatory responses promoting leukocyte infiltration the brain. Objective To assess serum levels and IL-22 children with autism. Methods A cross-sectional study, that was carried out at Child Psychiatric Clinic, Ain Shams University, Cairo, Egypt on...

A total number of 500 Japanese quail fertile eggs were used to study the effect in ovo (IO) administration Nano-Selenium (Nano-Se) and Glutamine (Gln) on hatchability, post hatch performance carcass some blood biochemical traits.Eggs divided into five treatments groups injected just before incubation.The 1 st group was not (Negative Control;T1), 2 nd one with Bovine Serum Albumin (BSA) (Positive control; T2), 3 rd Nano-Se at 2.5 ppb / egg (T3), while, 4 th (T4) 5 (T5) glutamine 20 10 ppm...

his study conducted to investigate the effects of dietary linseed oil (LO) or fish (FO) and/or antioxidants on productive performance, immune response, carcass traits and blood parameters broiler chickens.A total 168 one-day-old, Cobb chicks were obtained from a local commercial hatchery.The birds randomly divided into seven groups with three replicates, eight each.Birds fed iso-caloric iso-nitrogenous diets containing same ingredients (basal diet) except source addition antioxidants.The...

The effect of anti-heat stress agents on growth, immunity, lipid peroxidation and some physiological traits in Japanese quail during hot summer season were investigated.A total 360 one day old chicks randomly distributed into six groups 60 chicks, with almost similar initial average live body weight (LBW) three replicates 20 birds each.Experimental treatments included vitamin C (AA) levels (0.0, 0.5 1g/kg diet) two acetylsalicylic acid (ASA) (0.0 g/kg a factorial design (2x3).All exposed to...

The present work was conducted to evaluate the effect of dietary two levels vitamin E (250 and 500 mg/Kg diet) with/or without single dose thyroid hormone Thyroxin (0.25 diet), on biochemical physiological markers Laying hens (ISA Brown Strain).A total 120, 29 weeks-old layer, were housed in 120 pens assigned 6 diets groups, first group (control, receiving basal second third groups received diet supplemented with vit-E 250 mg/kg respectively, forth kept a level 0.25mg/kg diet; fifth sixth...

This experiment was conducted to evaluate the effects of partial or complete replacement clover hay by PNH (33.3, 66.7 and 100%) with without adding enzymes in diets growing rabbits.A total number 72 unsexed, weaned New Zealand White rabbits 6 weeks old were randomly divided into six experimental groups (12 rabbits/group).Six pelleted formulated be approximately isocaloric isonitrogenous cover recommended nutrient requirements rabbits.Clover replaced peanut (PNH) at rate 0, 15, 30 1gm...

One hundred eighty 14-d old Japanese quail chicks were individually weighed and randomly distributed into six treatments with three replicates, 10 each.The reared up to 42 days of age.Cadmium (Cd) in the form cadmium chloride (CdCl2.2½H2O) was added basal diet at 0, 5 50 mg/Kg or without 1000 units phytase supplementation.The results indicated that there marked reduction body weight feed consumption worse conversion ratio for birds fed ppm Cd while slightly noticed those received 5ppm...
