The egg is considered one of the best sources of dietary protein, and has an important role in human growth and development. With the increase in the world's population, per capita egg consumption is also increasing. Ground-breaking technological developments have led to numerous inventions like the Internet of Things (IoT), various optical sensors, robotics, artificial intelligence (AI), big data, and cloud computing, transforming the conventional industry into a smart and sustainable egg indus

Eggshells play a number of important roles in the avian and reptile kingdom: protection of internal contents and as a major source of minerals for developing embryos. However, when researching these respective roles, eggshell thickness measurement remains a bottleneck due to the lack of a non-destructive measurement techniques. As a result, many avian and reptile research protocols omit consideration of eggshell thickness bias on egg or embryo growth and development. Here, we validate a non-dest

The study of bioactive compounds like food antioxidants is getting huge attention and curiosity by researchers and other relevant stakeholders (e.g., food and pharmaceutical industries) due to their health benefits. However, the currently available protocols to estimate the antioxidant activity of foods are time-consuming, destructive, require complex procedures for sample preparation, need technical persons, and not possible for real-time application, which are very important for large-scale or

Embryonic movements, body and cardiac activity, are important physiological phenomena for chick embryo development. Currently, there is no complete non-invasive method for simultaneously quantifying chick embryonic body motility and cardiac rhythm during incubation. This study investigates the use of a near infrared sensor to simultaneously monitor embryonic body and cardiac movements. Light brown chicken eggs (ROSS 308) were incubated for chick embryos activity signals measurement from day 6 to

Non-destructive monitoring of chick embryonic growth can provide vital management insights for poultry farmers and other stakeholders. Although non-destructive studies on fertility, hatching time and gender have been conducted recently, there has been no available method for embryonic growth observation, especially during the second half of incubation. Therefore, this work investigated the feasibility of using near-infrared (NIR) sensor-based egg opacity values-the amount of light lost when pass

Some unresolved questions in poultry science were addressed: what determines the yield of chick embryos or hatchlings; what kind of influence does egg yolk content have on embryonic development; and how to detect eggs producing super grade chicks? Since the yolk acts as a vital energy and nutrient reservoir for embryos, we hypothesized that a higher yolk content of similar sizes eggs would play an important role in embryo or chick viability during incubation, as well as at hatch. As experimental

Culling of male day-old chicks in layer production is a big global ethical issue. As gender differences exist in the activity of human fetuses, such a physiological difference may also be true for chick embryos. Hence, this study investigated embryo (ROSS 308) gender differences based on this body motility. A near-infrared (NIR) sensor was used to measure embryo motility and separated it in frequency domain. Principal component (PC) scores from body motility strength (i.e., signal power in frequ

Food antioxidants can prevent or/and delay free radical formation which is responsible for oxidative stress. Nowadays, natural remedy is the highest concern in many countries, as well as discouraging the intake of synthetic counterparts to avoid the burden of side effects on human health. Regular intake of dietary antioxidants could help to improve the fitness of the body, and subsequently make the body more competitive in its fight against diseases through enhanced immune response. The present

Terahertz is a relatively new, and yet to be explored that how it interacts with many biological objects like avian eggshell. Eggshell protects internal contents of egg from contaminants and ultraviolet radiation. It also acts as a major mineral source for embryonic development. The refractive index indicating eggshell compactness could be a potential quality criterion of shell for both table and hatching egg. But a little is known about refractive index of eggshell. However, the available infor
