Gender Identification of Embryonic Chicken in the Egg by Heart Beat Modulation Technique

Abstract

The main goal of this study was to use a heartbeat modulation technique to determine the sex of a chicken embryo five days after incubation and investigate the effect of weight and temperature differences on the sex of the embryo. The embryo's growth after five days of incubation helps to determine the chicken's sex. As the temperature drops, so does the beat rate. In female embryos, the decline is more gradual. Female embryos have a faster rise in heart rate and return to normal after cooling. For the observation process, 200 fertilized eggs were collected and divided into four groups, and another 200 fertilized eggs were collected and divided into four groups for the identification process. Before incubation, the weight of 50 eggs from each group was measured, and five days later, the embryonic growth of each group's embryos was calculated, and samples were collected. The separation constant, embryo weight, and temperature are the essential factors in determining the embryonic chicken's sex. The relationship between heartbeat rate, embryo weight difference, and beat rate as temperature changes can be expressed as a first-order and first-degree differential equation. An integral combination can be determined and is of the form dy + Pydx = Qdx, where P and Q are only functions of x. Using this relationship, the separation constant c is equal to the difference between the heartbeat rate and the sine function of the embryo's weight difference over the cosine function of the embryo's beat difference during cooling. During the five-day incubation period, male chicks have an average beat rate of 62 beats per minute, while females have an average beat rate of 74 beats per minute. Male embryos gain weight faster than female embryos. As the temperature drops, so does the beat rate. In female embryos, the decline is more gradual. Female embryos have a faster rise in heart rate and return to normal after cooling.
