This study was conducted to consider the effect of theophylline in laying and some of egg characteristics on laying hens. Commercial egg type Hy-Line hens were used in a completely randomize design with 4 treatments and 3 replicates for 50 days period. The levels of different theophylline supplements (treatment) were 0 (control), one, three, and five mg per kg of body weight for 50 days. The av...
in this experiment, the effects of fennel and thyme extracts with and without flaxseed were investigated on performance and egg quality of leghorn-type laying hens (hy-line w-36). 200 laying hens from 26 to 38 weeks of age were assigned to five dietary treatments with five replications. the treatment groups were: 1) control (a diet without any additives); 2) control diet plus fennel (40 mg/kg f...

The aim of the current study was to investigate effect different storage period on some external and internal egg quality ovalbumin levels goose eggs. alterations these traits have not been examined sufficiently in eggs during storage. For this purpose, a total 150 were from 50 weeks-old German origin Embden geese. stored under constant temperature (+4°C) ~ 60-65% relative humidity conditions f...
Shell eggs were irradiated and the physico-chemical, and functional properties of egg yolk and white were determined. The color of egg yolk was not affected, but the viscosity of egg white was dramatically lowered and became watery by irradiation. The foam capacity and foam stability of egg white were significantly decreased due to protein oxidation by irradiation. However, the texture characte...
Two experiments were conducted to study the effects of red pepper (Capsicum frutescens) powder or red pepper pigment on the performance and egg yolk color of laying hens. In Exp. 1, 210, thirty-wk old, Hy-line Brown laying hens were fed one of seven diets containing 0.3, 0.6, 1.2, 2.0, 4.8 or 9.6 ppm red pepper pigment or 0.3 ppm carophyll red. Each diet was fed to three replicate batteries of ...
