The chorioallantoic membrane (CAM) containing tiny blood vessels is an alternative to large animals for studies involving angiogenesis and tissue engineering. However, there is no technique to design the direction of growing blood vessels on the CAM at the microscale level for tissue engineering experiments. Here, a methodology is provided to direct blood vessel formation on the surface of a th...
Economically success incomerical and Native laying hen farms in some eaten is related to egg quality. So, egg quality is a one of the most important factor affecting hatchability and lead to increasing the egg demand. The current study was carried out in aim to estimate the genetic parameters for egg quality traits in Fars native fowls. To do this, 2000 pedigree recorded eggs were collected at ...
This experiment was conducted to determine the phosphorus relative bioavailability of eight samples of dicalcium phosphate. Bioavailability of Samples of dicalcium phosphate was evaluated and their effects on performance of laying hens were investigated. Commercial samples of Dicalcium Phosphate were provided from the following manufacturers: Iran Phosphate, Partove Bashash, Godaze, Poya Khojas...

3. The microscopic structure of the egg envelopes is described. The egg is covered by three main envelopes: a hard, brittle exochorion built of seven distinct layers, two of which consist almost solely of calcium salts; a double-layered, membranous endochorion; a thin vitelline membrane. Layers of the chorion may be summarized as follows: (i) exochorion—tubercular layer, dark layer, lamellar me...
This study was conducted to estimate the genetic parameters influencing egg quality in Khorasan Razavi native fowl. (Co)Variance components were estimated by the Bayesian statistical method via Gibbs sampling in GIBBS3F90 software. 1000 eggs (28-29 weeks old) were collected from 775 hens of the ninth generation of Khorasan-Razavi Province native fowl breeding center. External (egg weight,specif...
