There are several factors that affect the size of the eggs: Feeding methods In the same environmental conditions, eggs raised in caged chickens are usually slightly larger than eggs raised in flat-raised chickens. The maturing weight of a hen usually results in a greater weight of the hen at the time of opening, and the greater the eggs it produces during its lifetime. To obtain larger eggs, do not use light stimulation to promote sexual maturity until the hens reach 1.5 to 1.6 kg body weight. The opening age of hens in hens is related to the size of their eggs. The sooner a chicken is opened, the smaller the eggs it produces and vice versa. Extending the hen's opening age can be achieved by delaying the extension of the light and controlling the weight of the hen. Seasonal and temperature hens producing hens in spring have a higher egg production rate than hens that were opened in the fall, and have a smaller egg weight. When the temperature of the laying house is above 27°C, the higher the temperature is, the smaller the eggs produced by the hens, and the temperature above 37°C can cause the hens to stop production or die. The size of the nutritional egg is also largely due to the influence of intake of crude protein, specific amino acids (such as methionine, cystine), energy, fat, and essential fatty acids (larodenic acid), and low protein levels. Diets can reduce egg weight. Decreasing the methionine content in the diet can reduce the egg weight, but it can also cause the egg production rate to drop. In addition, changes in the vitamin content of feed can also cause changes in egg weight. Researchers at the Ministry of Agriculture, Forestry, and Fisheries of the Ministry of Animal Husbandry found that the addition of linoleic acid in the diet of laying hens promoted an increase in egg weight. When the ratio of linoleic acid was increased to 2.83%, the egg weight was 59.6 g. If the eggs are too large, adding 5% taurine to the feed will reduce the egg weight by 1 gram.
