A method of determining the viability of an egg at least approximately 50% through its incubation period, which method comprises the steps of: (a) causing electromagnetic radiation to impinge upon the egg, the electromagnetic radiation having one or more wavelengths in the infra-red part of the spectrum; (b) receiving at least a part of the infra-red radiation that has passed through the egg and generating an output signal representative of the received infra-red radiation; and (c) processing said output signal to determine whether there is a cyclical variation in the intensity of the infra-red radiation leaving the egg corresponding to action of a heart, the existence of said cyclical variation indicating that the egg is viable; wherein step (a) is performed by directing infra-red radiation so that it passes through the shell for reflection from an outer surface of a vascular structure adjacent an inner surface of said shell, and step (b) is performed by receiving any infra-red radiation so reflected.

The invention discloses a production method of traditional Chinese medicine healthcare eggs, comprising the following steps of: 1, selecting a reasonable traditional Chinese medicine prescription which is used for preventing and treating the diseases of chicken sand improving the physique and nutritive ingredients of chickens; 2, fermenting the traditional Chinese medicine prescription to obtain fermentation solution and a fermentation body which are used for raising laying hens; 3, selecting laying hens from chicks, and raising by utilizing the fermentation solution and the fermentation bodyprepared in the step 2; and 4, obtaining the eggs laid by the raised laying hens during a laying period, i.e., the traditional Chinese medicine healthcare eggs. The eggs obtained through the production method disclosed by the invention have no hormones or antibiotics, traditional Chinese medicine constituents furthest exert efficacies after being fermented, and the eggs are natural, free from toxic or side effects, and free from medicine resistance; the production method is suitable for large-scale breeding, simple in operation, purely ecological, and pollution-free; and the produced eggs canbe taken as both food and medicines, has healthcare effect and is capable of treating diseases.

The invention discloses a preparation method and application of an egg shell membrane composite nano-silver thin film used for an artificial skin. The preparation method comprises the following steps: removing egg white and yolks of fresh eggs and washing egg shells with de-ionized water; separating egg shell membranes and washing the egg shell membranes with the de-ionized water; cutting the egg shell membranes into sizes of (1cm-3cm)*(1cm-3cm) and putting the egg shell membranes into a hydrochloric acid solution with the concentration of 1mM to 100mM and the pH (Potential of Hydrogen) of 1 to 3; immersing for 1 to 4 days at room temperature and washing with the de-ionized water; then putting the egg shell membranes into a dopamine solution with the concentration of 2mg / mL to 4mg / mL and the pH of 8.5 to 9.5; immersing for 6h to 20h at room temperature and washing with the de-ionized water; then putting the egg shell membranes into a silver nitrate solution with the concentration of 10nM to 50nM; immersing for 6h to 20h at room temperature without light, and then washing with the de-ionized water; and naturally drying at room temperature to obtain the egg shell membrane composite nano-silver thin film used for the artificial skin. The prepared egg shell membrane composite nano-silver thin film is used for manufacturing the artificial skin, has excellent mold resistance, and has no obvious biological toxicity; and the preparation method is simple in process, less in consumed time and low in cost.

The invention relates to a coating preservation method for eggs. The method comprises the following steps: (1) selecting fresh and crack-free eggs, cleaning the eggs and then adding water to soak the eggs; (2) taking 1 to 2 parts of xanthan gum, 1.6 to 2.05 parts of composite plant essential oil, 0.125 to 0.25 part of licorice flavonoids, 30 to 35 parts of an emulsifier and 50 to 100 parts of ganoderma lucidum polysaccharide, mixing the above-mentioned materials and adding the obtained mixture into water under stirring so as to obtain 1000 parts by weight of an essential oil emulsion; and (3) taking the essential oil emulsion and water according to weight parts, mixing the essential oil emulsion and water so as to obtain a spraying liquid, coating the shells of the eggs with the spraying liquid and drying the eggs at 37 DEG C in the air for preservation. According to the invention, the surface of each egg is coated by a layer of a preservative film which inhibits enzymatic activity of the eggs, alleviates decay of life, achieves the purpose of freshness and quality retention, increases the shelf life of the eggs and saves social cost; moreover, the coated preservative on the surfaces of the eggs is colorless and transparent after drying, so the advantages of safety and low cost are obtained.

The invention relates to a method for detecting parasitic eggs, which is carried out according to the following steps and is calculated according to the following formula: firstly, livestock feces to be detected are quantified, and water in the volume of 3 to 5 times of the volume of the quantified feces is added so that the feces and the water are stirred into paste; the paste is filtered by a copper screen while washed and filtered by a right amount of water; a filtrate is precipitated for 15 minutes to 60 minutes or is centrifugated, supernatant is discarded, water is added for precipitation, and the procedures are repeated for three times; a right amount of supernatant is discarded, and a measuring cylinder is used for quantifying precipitated liquid; after the precipitated liquid is shaken to be full uniform, a dropper is used for rapidly moving the precipitated liquid to two counter chambers of a counter; and finally, the parasitic eggs in square grids of the two counter chambers of the counter are observed and countered so as to calculate an EPG (Eggs per Gram) value according to the following formula: EPG = (the number of the eggs in the two small square grids of the counter * the volume of the precipitated liquid of the feces) / (the weight of the feces * 0.2). The invention has simple and rapid operation and reliable results, is suitable for detecting most of the parasitic eggs through the feces excretion eggs of people and livestock, and particularly, can qualitatively and quantificationally detect eggs hardly detected so far, such as the eggs of fasciola spp, acanthocephala and distomes, thereby having a wider range of application.

Methods and apparatus for producing vaccine within a plurality of eggs are provided. Each of a plurality of eggs is illuminated with light from one or more LEDs. A detector is positioned adjacent each egg and detects light passing therethrough. Each egg is then identified as containing a live embryo or as being a non-live egg. Each egg that is determined not to contain a live embryo may be removed, either automatically or by hand. A seed virus is injected into each egg identified as containing a live embryo. After a predetermined period of incubation each live embryo is euthanized and amniotic fluid containing a vaccine produced as a result of the presence of a seed virus is harvested from each euthanized egg.

The invention discloses a method and a system for monitoring egg laying performance of a laying hen zone of cage-rearing laying hens. Wherein coops are arranged side by side, a conveying belt is arranged below the coops, and a machine vision detection device with a CCD camera and a lighting device is arranged at the conveying outlet end of the conveyor belt; chicken lay eggs and the eggs leak fromthe bottom of the hencoop and fall onto the conveying belt, after all eggs are laid, the conveying belt is started, the eggs pass through the machine vision detection device in the conveying processalong with the conveying belt, the CCD camera is triggered to shoot and obtain conveying belt surface images with the eggs, and egg contours in the images are obtained through image processing. And counting is performed to obtain the number of eggs, and processing is performed to obtain the coop area position, the egg color, the egg size and the egg weight of each egg, thereby realizing real-timemonitoring. According to the system, the change conditions of the egg laying number, the egg weight and the egg color of each egg laying area every day can be monitored, the egg laying performance andthe health condition of the laying hen area are monitored, the system is simple, and the cost of breeding equipment is saved.
