Chicken Eggs

The production of chicken eggs in the world, without slowing down, has passed for 1 trillion pieces. In conditions of saturation and oversaturation of many local markets, food eggs are transported to other remote regions or stored in warehouses, store shelves, losing their freshness and nutritional quality. The ozone can be used to disinfect the surface of chicken eggs, which suppresses microorganisms. Based on the disinfection and disinsection properties of ozone, it is proposed to treat chicken eggs with ozonated air after sorting them by opto-electronic method. (Research purpose) The research purpose is in developing a method for surface disinfection and optoelectronic sorting of food and refrigerator chicken eggs, studying the effectiveness of the performed operations in comparison with traditional methods. (Materials and methods) Authors studied the efficiency of the optoelectronic system for sorting and electrozoning chicken eggs on the basis of a laboratory installation in the Kuban State Agrarian University. The reliability of the results is confirmed by a multiply repetition of research and reproducibility of the data, the use of generally accepted methods, instruments, and mathematical processing of experimental data. (Results and discussion) The article presents an experimental study to determine the effectiveness of electrozoning of chicken eggs in comparison with traditional methods. The article describes rational parameters and modes of operation of the optoelectronic installation for monitoring chicken egg shells. (Conclusions) The article presents an analytical description of the ratio of the main parameters of an optoelectronic installation for monitoring chicken egg shells. The article presents a basic electrical diagram for studying the parameters and operating modes of the installation. The greatest efficiency of electrosonation of chicken eggs is achieved when the ozone concentration is of 1000 milligrams per cubic meter and the ozonation time is 30 minutes; up to 99 percent of harmful microorganisms and viruses on the shell are eliminated.

Chicken Eggs

Poultry farms in Russia use machines for sorting chicken eggs, which determine the category by weight. Eggs are ovoscoping, that is, the evaluation of the main parameters of the egg contents: the condition of air cell, position of yolk and protein density. The category is assigned based on the worst indicator. During ovoscoping, the device receives only part of the image of the shell, which reduces the accuracy of category assigning and it is not possible to fully check the shell of a chicken egg for the microcracks. (Research purpose) The research purpose is in improving the optoelectronic device for sorting chicken eggs, which will detect microcracks on the shell, as well as improve the accuracy of category assigning. (Materials and methods) The article presents a device for sorting chicken eggs. (Results and discussion) This device was upgraded by adding a camera and changing the distribution mechanism. The improved installation works as follows: a chicken egg is fed via a conveyor to a switchgear that has holes with clips; when the disk is rotated, the product is scanned with two cameras. The resulting image is fed to a computer, where using the algorithm "recognition of alfalfa seed parameters", the main parameters of the egg are calculated and a category for the product is assigned. Authors obtained a complete image of the surface of a chicken egg and determined the presence of microcracks on the shell. (Conclusions) The algorithm used requires several additional calculations to determine the state of the air chamber, the position of the yolk and protein density, and microcracks on the surface of the shell.

Design Characteristics

Creating and maintaining a microclimate in animal housing is an energy-intensive technological process that consumes up to 70 percent of the thermal energy consumed on cattle farms. Improving heating and ventilation systems aimed at reducing energy consumption is an urgent task. (Research purpose) The research purpose is to analyze the theoretical models for calculating air curtains and evaluate the possibility of their use for agricultural production facilities and to identify promising directions in the design solutions for thermal air curtains aimed at rural consumers. (Materials and methods) The article considers the theoretical justification and calculation of air curtains. The authors studied the physical model of interaction of air jets in openings, which serves as the basis for mathematical calculation of air curtains in engineering practice. The article describes the features of using the models for calculating air curtains for agricultural objects and the energy parameters of the curtains depending on the design characteristics and external environmental factors. (Results and discussion) The effect of the air curtain on the energy characteristics of the room has been studied. It was found that it is necessary to determine the type of air curtain that is optimally suitable for protecting the gate opening, with or without heating the air curtain. Authors have found that the engineering methods of calculation are based on different experimental data, which leads to a discrepancy in the results of evaluating the effectiveness of the designed curtain, overestimating its energy intensity and power. The calculation of heat curtains, operating modes should be carried out taking into account the variable effects of external physical factors, the equipment should correspond to a specific room. (Conclusions) The use of air curtains reduces or eliminates the penetration of external cold air into the room through the openings of external gates, requires a smaller volume of air supplied by the curtain, compared to the mass of the incoming air flow.

SUMMARYWe examined 20 300 raw shell chicken eggs sold at retail stores in Japan for Salmonella outside and inside eggs. The eggs were purchased at 220 retail stores throughout Japan between August 2007 and January 2008. Of 2030 pooled egg samples (10 eggs/sample), Salmonella was isolated from five shell samples (0·25%), but not from any of egg-content samples. The serovars of the isolates were Salmonella Enteritidis (2), S. Derby, S. Livingstone and S. Cerro. The samples positive for Salmonella originated from five different egg grading and packaging (GP) centres. All the GP centres washed their egg shells according to government guidelines for hygienic practice in GP centres. Thus, practical control measures at GP centres need to be reviewed and implemented to diminish Salmonella prevalence of egg shells because Salmonella contamination on eggs is a potential hazard for foodborne salmonellosis in Japan.

Chorioallantoic Membrane Assay

Chorioallantoic membrane assay (CAM assay) using fertilized chicken eggs has been used for the study of tumor formation, angiogenesis and metastasis. Recently, there is growing realization that this system provides a valuable assay for a patient-derived tumor model. Several reports establish that tumor samples from cancer patients can be used to reproduce tumor in the chicken egg. High transplantation efficiency has been achieved. In this review, we discuss examples of transplanting patient tumors. We then discuss critical issues that need to be addressed to pursue this line of experiments. The patient-derived chicken egg model (PDcE model) has an advantage over other models in its rapid tumor formation. This raises the possibility that the PDcE model is valuable for identifying optimum drug for each individual patient.
