Relationship Between Shell and Shell Membrane Strength and Other Egg Shell Characteristics
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...
متن کاملThe Avian Egg: Surface Area, Volume, and Density
The surface area of the avian egg through which the developing embryo must exchange heat, metabolic gases, and water vapor is a variable of prime importance for quantitation of the permeability of the egg shell to these substances. Surface-area measurements are necessary if one is to compare the permeability properties of shells ranging in size from less than 0.5 g in hummingbirds, to 1.5 kg in...

متن کاملEffect of Lemon Juice on the Egg Shell Quality of Layers Subjected to Heat Stress
Heat stress is an effective factor on immune responses, body weight, egg production and egg quality of chickens. The major effect of heat stress is due to decreased food intake and alteration in acid-base balance. During the recent years, efforts to improve laying performance at high temperatures have been relatively successful. Supplementation of the diet or drinking water with special nutrien...
