Most manufacturers of laying hens use layer chicken cage to raise laying hens, which will increase the amount of farming and the production of eggs. It is important to know that eggs will also bring economic benefits to the farmers. If it is too thin, it is easy to cause damage to the eggshell when collecting eggs, causing economic losses. Taking corresponding measures to improve the strength of the eggshell is of great significance to improving the economic benefits of the farmers. So how to improve the strength of eggshells?
First, environmental factors. This effect on the eggshell is slow and undetectable. According to the implementation of the relevant data. The suitable ambient temperature is generally between 16 and 24 °C. Adjust the illumination time according to the light program: the general illumination time is 16 to 17 hours, and the egg production period can be increased by 1 to 2 hours. Reduce stress, minimize or eliminate all kinds of stress during feeding, improve the quality of chicken population, and enhance the resistance to disease. Increase the number of eggs collected, large groups of laying hens 4 to 5 times. The design and installation of the cage should be scientific, and the slope of the cage should
be reasonable.
Second, disease control. This is very clear to everyone, the invasion of Newcastle disease and infectious bronchial and white sputum can cause the eggshell quality to decline. Also pay attention to the use of drugs when controlling diseases. Laying hens are prohibited from using sulfonamides and furans during laying. Other antibiotics should be used instead of sulfonamides during the laying period. Laying hens drinking disinfectant water containing excessive bleaching powder or other disinfectants containing chlorine also affect the quality of the eggshell.
Third, genetic factors. This is a germplasm problem. Under the same feeding and management conditions, hens with good genetic performance can use calcium better than genetics, which makes the eggshell thicker. Generally, brown shell eggs have higher eggshell strength than white shell eggs. Therefore, in order to improve the quality of the eggshell, we must pay attention to the choice of chicken varieties.
Fourth, feed nutrition. This is what we usually pay attention to, which is the so-called acquired compensation. At present, all kinds of laying hens have a standard feeding system, so we need to produce full-price compound feed according to the feed formula. When making the feed, first pay attention to the calcium content in the egg production, and choose some calcium sources with good solubility such as limestone, but pay attention to the content of magnesium and fluorine in the test. Secondly, the content of available phosphorus in the feed should be ensured, and the appropriate ratio of calcium to phosphorus should be mastered. After zui, add enough vitamin D3, vitamin C, and other minerals to the feed to ensure normal nutritional needs and ensure eggshell quality in poultry farming equipment.
