An experiment was conducted to evaluate the potential dietary interaction between 1,4-diaminobutane (putrescine) and calcium on eggshell quality and overall laying performance. One hundred ninety-two 30-wk-old White Leghorn hens were fed a corn-and soybean-meal-based diet supplemented with 0.00, 0.05, 0.10, or 0.15% putrescine and 2.5, 3.0, 3.5, or 4.0% calcium in a factorial design (12 birds p...

Eggshell quality is the main trait to assess egg quality. Marker assisted selection can be used to improve this trait. During eggshell formation, a mass of inorganic minerals is deposited. The Sodium Channel (SCNN1) gene family plays an essential role in cation transportation and SCNN1g is a member of this gene family. The objective of this study was to estimate the frequency of SCNN1g gene var...

A multitude of autogenous/allogeneic and semi-synthetic bone graft materials have been developed to reconstruct the defective tissue but with high bio-cost potential environmental pollution. With calcium content several trace elements, chicken eggshells are no longer considered as wastes attractive sources high-value-added biomaterials. This study used synthetic hydroxyapatite (HAp) synthesize ...

Eggshell is the most abundant agricultural (hatchery) and industrial (confectionary) natural waste approximately reaching up to 50000 tons per year a threat environment public. membrane shell can be used for biomedical applications as value-added products. Hence, scoping review was planned understand present scenario knowledge gap; it also explored eggshell separation methods available commerci...

Eggshell mechanical property traits such as eggshell breaking strength (ESS), eggshell thickness (EST) and eggshell weight (ESW) are most common and important indexes to evaluate eggshell quality in poultry industry. Uterine ion transporters involve in eggshell formation and might be associated with eggshell mechanical property traits. In this study, 99 SNPs in 15 ion transport genes were selec...

in this project, eggshell membrane was used as a solid phase extraction sorbent for extraction of morphine followed by hplc analysis. at first, raw eggshell membrane was used and then, because of low adsorption of morphine on untreated eggshell membrane (

Biodiesel is a promising green alternative fuel for compression ignition engines (C.I.E.s) made from vegetable oil or animal fat transesterification. Compared to traditional diesel fuel, biodiesel becomes vital fuel. Due high input feed and product purification costs, existing production systems offer less competitive prices than petroleum-derived diesel. Non-edible oils, such as waste cooking ...

Eggshell quality is one of the most significant factors affecting poultry industry; it economically influences egg production and hatchability. Eggshell consists of shell membranes and the true shell that includes mammillary layer, palisade layer, and cuticle. Measurements of eggshell quality include eggshell weight, shell percentage, breaking strength, thickness, and density. Mainly eggshell t...

s of papers 97 eggshell breaking strength, and eggshell percentage were no affected by treatments(P>0.05). Only eggshell thickness was affected by treatments (P<0.05), and RL showed the highest value( 0.1862 mm), followed by BL (0.1785mm).
