There was a significant difference in the shell strength of chicken eggs with different curvatures of the large end. Holding temperatures of eggs significantly influenced shell strength but not shell membrane strength. There was a significant negative correlation in chicken eggs between shell strength and membrane strength in small and medium curvature groups but not in the large curvature grou...

introduction breeding quail and quail egg industrial production because of the high nutritional value of these products has been developing these years. considering the high demand and economical production, further development in the future is predicted. in order to design and effective utilization of the equipment for transportation, separation, packaging and storage, the physical and mechani...

this experiment was carried out to study the effect of sodium chloride from drinking water and feed intake on the quality of egs from laying hens. four hundred and twenty native and white leghorn laying hens ranging from 36 to 43 weeks of age were used. seven experimental treatments containing different levels of salt supplied by feed and/or drinking water were compared. increasing salt int...

Shell quality has been identified as a heritable trait that can be manipulated by genetic selection. Previous research has concluded that many methods of determining shell quality produce variable results. With the development of newer, more precise measuring technologies, shell strength can now be assessed in a consistent, objective fashion. A research project was conducted to determine what r...

BACKGROUND A common clinical scenario encountered by an orthopaedic surgeon is a patient with a secure cementless acetabular shell and a failed polyethylene liner. One treatment option is to cement a new liner into the fixed shell. The purpose of this study was to evaluate technical variables to improve the mechanical strength of such cemented liner constructs. METHODS The contributions of sh...

the present study was carried out to investigate the effect of corn replacement by different levels of wheat with supplementation of phytase with reduced phosphorus level for laying hens. two hundred seventy nine layer hens (the strains of hy-line w36) at the 53th week of age, selected based on the same egg production percentage and body weight, assigned in a factorial arrangement with complete...

Researchers are currently developing new value-added uses for almond shells, an abundant agricultural by-product. Almond varieties are distinguished by processors as being either hard or soft shelled, but these two broad classes of almond also exhibit varietal diversity in shell morphology and physical characters. By defining more precisely the physical and chemical characteristics of almond sh...
