The Effects of Intrauterine Injection with Prostaglandin F2α, Arachidonic Acid and Phosphate Solution on the Eggshell Formation of Japanese Quail Hen

The Journal of Poultry Science, 2002
Inhibitory effects of prostaglandin F2α, arachidonic acid and phosphate solution on the eggshell formation were investigated in Japanese quail. All injections were performed intrauterinely 8h before the predicted oviposition. Prematurely oviposited

Co‐Electrospinning Extracellular Matrix with Polycaprolactone Enables a Modular Approach to Balance Bioactivity and Mechanics of a Multifunctional Bone Wrap

Advanced Healthcare Materials, EarlyView.
The incorporation of nondigested ECM and synthetic polymers into a co‐electrospinning system enables the decoupling of bioactivity and mechanical properties within a single wrap. This technique is used to develop a multifunctional bone wrap that achieves augmented membrane durability, sustained infection control, and enhanced vascularity for use in ...

Effect of crude protein levels and organic selenium supplementation in the diets fed during the breeding season on reproductive parameters of red-winged tinamous (Rhynchotus rufescens) [PDF]

, 2010
There is little information on the nutrition of red-winged tinamous (Rhynchotus rufescens) reared in captivity, and their nutritional requirements still need to be determined. This study aimed at determining dietary crude protein requirements and testing
