Inositol tetrakisphosphate from chicken eggshell

Objective.The objective of this study was to investigate changes in pigment, spectral transmission and element content of chicken eggshells with different intensities of pink pigment during the incubation period. We also investigated the effects of the region (small pole, equator and large pole) and pink pigment intensity of the chicken eggshell on the percent transmission of light passing through the chicken eggshells.Method.Eggs of comparable weight from a meat-type breeder (Meihuang) were used, and divided based on three levels of pink pigment (light, medium and dark) in the eggshells. During the incubation (0–21 d), the values of the eggshell pigment (ΔE,L∗,a∗,b∗) were measured. The percent transmission of light for different regions and intensities of eggshell pigmentation was measured by using the visible wavelength range of 380–780 nm.Result.Three measured indicators of eggshell color, ΔE,L∗anda∗, did not change significantly during incubation. Compared with other regions and pigment intensities, eggshell at the small pole and with light pigmentation intensity showed the highest percent transmission of light. The transmission value varied significantly (P< 0.001) with incubation time. The element analysis of eggshells with different levels of pink pigment showed that the potassium content of the eggshells for all pigment levels decreased significantly during incubation.Conclusion.In summary, pigment intensity and the region of the eggshell influenced the percent transmission of light of eggshell. Differences in the spectral characteristics of different eggshells may influence the effects of photostimulation during the incubation of eggs. All of these results will be applicable for perfecting the design of light intensity for lighted incubation to improve productivity.

Negative Controls

Efficacy of chicken eggshell powder at concentrations 0, 0.25, 0.5, 1.0 and 2.0 g /100 g maize, for control of Sitophilus zeamais, were compared with permethrin at dosage rate of 0.167g / 100 g of yellow maize. Experiments were conducted at Biotechnology laboratory (NSPRI), Ilorin under ambient condition (26±3oC 65±5% RH). Mortality of S. zeamais increased with increasing dosages of the CESP as well as with days of exposure. CESP at 2.0g gives 96.67% mortality which is not significantly different from the positive control. The mean progeny emergence (0.00%), weight loss (1.11%), and percentage grain damage (19.68%) by S. zeamais was significantly (P ≤ 0.05) decreased with increased dosage of CESP. However, CESP did not significantly affect seed germination. Total coliform count at 2.0 g (2.48 x 102) was significantly different from both positive and negative controls at p<0.05 Therefore, CESP can serve as a good maize protectant which can be used as substitute for synthetic chemicals.

Hydroxyapatite (HA) is a bioceramic with excellentbiocompatible properties, and composition and crystal structure similar to apatite in the human dental structure and skeletal system. A number of researchers have attempted to evaluate the effect of the addition of HA powders to increasemechanical properties of restorative dental materials. In this study, HA was synthesized using chicken eggshell as calcium source for synthesizing HA by using precipitation technique. The aim of this study was to determine the effect of incorporation of eggshell-derived HA on the surface hardness GIC (Fuji IX GP). Specimens were divided into two groups: group GIC without incorporation of HA as control group (n = 16) and group GIC with incorporation of 5% HA as experimental group (n = 16). Total of specimens were 32 cylinders 5mm diameter and 2mm height. Surface hardness GIC was measured with vickers microhardness tester. Data wasanalyzed by unpaired T-test. The mean of surface hardness for GIC control group was 51.37 ± 1,63VHN and the experimental group was 56.60 ± 1,22HVN. The results T-test showed a significant difference between groups (p<0.05). It can be concluded thatincorporation of eggshell-derivedHA could increasesurface hardness of GIC.
