Egg Weight Egg weight or egg mass are one of the easier ways to determine if the flock is performing properly. It is the average weight of an egg or the overall weight of all eggs produced in a flock. The egg weight should should begin to increase weekly from the moment the hens lay their first 48 gram egg. The egg weight increases till it reached around 60 grams at around 30 weeks of age. In later production till the end, the egg weight will be between 65 and 70 grams which may fluctuate 0.5 grams per week, any more than that is cause for concern.
The Incredible Egg The purpose of this lab was to find out what would happen over time to weight of an egg after we scrubbed the eggshell off in a little spot. We then soaked it in water for 10 minutes, 30 minutes, 24 hours and measure how much the weight went up. Once we came back the next day we measured them after 24 hours. In the same day we put the syrup in the cup instead of water and we measured how much it weighed after 10 minutes, 30 minutes and 24 hours. As we did this with the water the weight of the egg went up because the water soaked into the egg and made it heavier.
The average egg size ranges from 120 – 130 um in diameters. Because of the short longevity of the sperm (about 30 minutes), the sperm is obtained shortly before fertilization. It is recommended to select the best quality sperm –based on motility and number- via microscopic examination using Sedwegick and Neubauer chambers. Fertilization: Washed eggs are transferred into containers of 10-12 liters whereas about a million ovules are placed in 1-um filtered and UV-irradiated seawater and at 17 – 18 °C. Fertilization is carried out by adding one ml of sperm solution with approx.
An egg naturally has a lot of stuff inside, so the outside solution has to be very concentrated for this to happen. That’s the case when an egg is treated with corn syrup or buried in salt. By contrast, when an egg is treated with distilled water, or a dilute salt solution, the solute concentration is higher inside the egg than out, so the water moves into the egg, increasing its mass. It may be easier to think about osmosis in terms of water concentration rather than solute concentration. If the solute concentration is high, then the water concentration will be low by comparison.
The sun and outdoor temperatures can increase or decrease the temperature of the incubator depending on the season and time of year. (Hamre, 2016). It is known that a positive relationship exists between egg size and chick weight when it comes to hatchability (Abiola et al., 2008; Shananwany, 1987). In another study with hatchability, Abiola (1999) reported that egg size typically affects hatching size in chickens because the main effect of egg size lies in the mass of the residual yolk sac that the chick retains at hatching. Usually, eggs with bigger sizes produce chicks with higher weight than the eggs with smaller
