In this study, hatchability characteristics and some internal egg quality characteristics of 0, 2, 3, 4, 6 and 8 d stored Fayoumi eggs were examined. It was determined that the effect of storage time on hatchability, hatchability of fertile eggs, embryonic mortality, hatchling weight, albumen weight, yolk weight, albumen index, yolk index and Haugh unit was significant (P<0.05). There was no positive or negative effect of storage time on the fertility rates, but there was a negative effect of storage time on egg weight, hatchability, embryonic development and hatchling weight on d 4 (P<0.05). It was determined that prolonged storage time caused a decrease in the albumen weight, yolk weight, albumen index, yolk index and Haugh unit value of Fayoumi eggs. Fayoumi eggs should not be stored more than 3 d.

Here an attempt has been made to investigate the magnetohydrodynamic (MHD) flow of a non-Newtonian fluid filling the porous space in a channel with compliant walls. Constitutive equations of a Jeffery fluid are used in the mathematical modeling. The flow is created due to sinusoidal traveling waves on the channel walls. The resulting problem is solved analytically and series solution for a stream function is derived. The effects of pertinent flow parameters are discussed through graphs.
