heavy metal contamination in the environment could cause harmful effects both to human health and aquatic life. numerous remediation methods had been developed to encounter with the contamination problem prior to degrade, decrease and to purify the contaminated water at minimal concentration as low as possible. therefore, in current study, commercialized chicken eggshells and hybrid akar putra ...
Minerals are used widely as feed additives in the diets of poultry to enhance bone and egg quality productivity. Therefore, current study aimed evaluate impact strontium ranelate cerium oxide addition diet on production eggshell laying hens. In this experiment, a total 240 hens at age 44 weeks old, were divided into six treatments, with four replicates per treatment (10 replicate). The fed stan...
Fluoride is a toxic substance that can cause adverse effects on human health such as dental and skeletal fluorosis. Therefore, the objective of this study was to investigate adsorption potential fluoride from aqueous solution using eggshell pretreated with plasma technology compare untreated eggshell. The batch experiments were carried out their performances removal efficiency, capacity isother...
Eggshell was found to be a versatile heterogeneous catalyst for the synthesis of pyrano[3,2-c]quinoline derivatives in good yields. This protocol has the advantages of environmental friendliness, short reaction time, low cost and convenient operation.
Eggs exhibiting eggshell apex abnormalities (EAA) were evaluated for changes in shell characteristics such as strength, thickness, and ultrastructure. Mycoplasma synoviae (MS) infection was confirmed by serological assay along with isolation of MS from the trachea and oviduct. Changes in eggshell quality were shown to be statistically significant (p < 0.01). We also identified ultrastructural c...
The fine structure of the eggshell of blow fly, Lucilia cuprina (Wiedemann) (Diptera: Calliphoridae), was examined using scanning and transmission electron microscopy. Eggs, 1.09+/-0.07 mm in length and 0.25+/-0.05 mm in width, bore a relatively wide plastron that extending along almost the entire length. The polygonal pattern of chorionic sculpture was indistinct. The ultrathin section indicat...
Calcium pyrophosphate (CPP) was prepared by a simple precipitation method using avian eggshell waste as a low-cost alternative calcium precursor source. The synthesized CPP powder was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM/EDS), thermogravimetric analysis (TGA), and Fourier transform infrared spectroscopy (FTIR). The results indicate that pure b-CPP nanocrys...
The purpose of this study was to establish the effects of ultrasonic treatment of eggs on egg weight loss, hatchability, tibia mineral content, chick performance, and eggshell microbial activity. A total of 600 fresh eggs was randomly divided into 5 groups. Treatments were no ultrasound, 35 kHz for 5 min, 35 kHz for 10 min, 35 kHz for 15 min, and eggs sprayed with benzalkonium chloride solution...
