Now is the time to replace chickens. Many old chickens are about to be eliminated. It is the peak season for brooding and the most crucial period for chicken farmers. At this time, the chicken farmers must ensure the quality of the eggs, so today Xiaobian will introduce the source, selection and preservation methods of the eggs.
1, the source of eggs
A good quality chick comes from a healthy egg, and the health of the egg depends on the health of the breeder. Therefore, it is necessary to select the breeder that has been scientifically managed as the mother of the seed, the breeder is healthy, and the breeding ability is strong, so as to ensure the high egg production rate and the fertilization rate and hatching rate of the eggs. The health status of the flocks determines the quality of the eggs, which determines the indicators of hatching and the quality of the chicks. It is the basis of chicken farming.
2, egg selection
Although good quality eggs are obtained in healthy breeders, not all eggs are suitable for hatching. To select clean and non-polluting among all the eggs, the egg weight is between 52g and 68g, the egg shape index is 0.72~0.75, the specific gravity is about 1.08, and the steel egg, sand egg and wrinkled egg and broken egg are cracked. Eggs, etc., eggshell color should meet the requirements of this variety.
3, egg storage
Generally, the egg should be kept for 5 days to 7 days, preferably not more than one week. Especially for old-aged eggs, the preservation period should be shortened as much as possible. Eggs should be kept in an egg store with insulation and air conditioners to adjust the temperature inside the store. The temperature is between 13 ° C and 18 ° C (the short time is the upper limit of the temperature, the longer the time is the lower limit), and the relative temperature is maintained at 75% to 80% (which can significantly reduce the evaporation of water in the egg and prevent the growth of mold). Maintain good air permeability conditions in the egg store.
The above is the source, selection and preservation method of the eggs. The quality of the eggs determines the quality of the hatching. It is the key to the breeding of the chicken farmers. The chicken farmers must pay attention. I hope the above can help the chicken farmers. .
