“…Balloun and Miller (1964) used diets containing 1.5, 2, 2.5, 3% calcium level for turkey hens and reported that the best hatchability was recorded when hens received diet with 2% or 2.5% whereas hatchability was depressed by 1.5 and 3% calcium level. Similar results were also obtained by Menge et al (1977), Abd El-Rahman (1979 and Rouqe and Soares (1994).…”

“…Packaging of hatching eggs improved hatchability (P<0.01) by about 4%. Menge et al (1977) and Abd El- Rahman (1979) found that the use of plastic bags for packaging of hatching eggs reduced occurrence dead embryos, decreased markedly moisture loss and Co 2 from them and hence increased their hatchability. The best hatchability was also found in the group of the lowest egg weight loss (Packaged eggs).…”

A total number of 5030 hatching eggs were produced from three genotypes namely; homozygous naked neck (Na/Na), heterozygous naked neck (Na/na) and normal feathering (na/na) genotypes to investigate the effect of some treatments to reduce egg weight loss during storage and incubation which may contribute to the improvement of hatching results of Sharkasi chickens. The results are summarized as follow: 1-Effect of packaging.-The Na/-birds exhibited higher egg weight loss during storage or incubation period as compared with na/na genotype. Packaging (versus non-packaged) of eggs reduced significantly (P<0.01) egg weight loss. -The differences due to genotype or packaging method on fertility was insignificant. -Packaging reduced significantly (P<0.01) the total embryonic mortality and improved hatchability by about 4%. The Na/-birds exhibited a remarkable reduction in hatchability and most of losses in embryos occurred mainly during the last stage before hatching. -A significant (P<0.05) interaction between packaging and genotype was found where packaging improved hatchability of the Na/-eggs by about 5.5% and 5.4% for the Na/Na and Na/na genotypes as compared with 0.9% for the na/na genotype. 2 -Effect of calcium level. -Differences due to genotype or dietary calcium level on fertility were insignificant. -High dietary calcium level (3.47%) reduced significantly (P<0.01) egg weight loss as compared with low dietary calcium (2.51%). Also, it reduced the total embryonic mortality by about 3.80%. -Although, dietary calcium level did not affect hatchability, the birds receiving high dietary calcium had higher hatchability (82.5%) than birds receiving low dietary calcium (79.7%). -The interaction between calcium level and genotype was significant (P<0.05) where the hatchability from birds receiving high dietary calcium was 77.7%, 85.4%, 84.4% for Na/Na, Na/na and na/na genotypes, respectively. The corresponding figures for birds receiving low dietary calcium level were 70.20%, 78% and 90.70%. It can be concluded that, packaging of eggs in polyethelene bags and feeding on high dietary calcium level (3.47%) are effective means for reducing egg weight loss and hence improving the hatching ability of the naked neck birds.

“…Strontium 90 and its daughter Yttrium emit beta particles having energies of .61 MEV and 2.18 MEV respectively and a half life of 28 years (Strominger et al, 1959). During research of (Menge et al, 1977) the beta backscatter gauge did not give consistent readings from the same reflector. When the gauge was cold, more backscatter counts were indicated.…”

“…A large backscatter count indicates there is a high calcium content in the shell. Menge et al (1977) used backscatter counts to determine the relationship between turkey egg shell thickness and shell calcium content with different levels of dietary Vitamin D3 and calcium in the diet. Their results showed that eggs that hatched had a higher backscatter count than those which did not hatch.…”

Three beta-backscatter gauges used to determine egg shell properties were compared. One gauge had a large diameter 5.4 cm Geiger-Mueller detector. The second gauge had a small diameter, 2.9 cm Geiger-Mueller detector; whereas, the third gauge had a small diameter, 2.9 cm surface barrier detector. The most consistent measurements were obtained with the large diameter Geiger-Mueller detector gauge. While all gauges were affected by temperature changes, the Geiger-Mueller detectors were affected least. A temperature change of the electronics created a much greater change in counts than a similar temperature change of the detectors. The differences between good and poor egg shells were determined by measuring the backscatter with each gauge. Although the gauge with the large Geiger-Mueller detector showed a smaller difference between good and poor egg shells than the one with a surface barrier detector, its superior reliability and temperature stability make it the preferable gauge.1979 Poultry Sci 58:361-364
