Why do laying hens lay eggs every other day when they just start laying?

1.Genital branch: Even if a flock has been vaccinated against the branch, there is no guarantee that 100% of the chickens will not be infected.

If the flock has symptoms of bronchial blockage around 70-80 days, even if the flock is immunized, the reproductive system of the flock may be damaged, affecting the normal development of the fallopian tubes. But it does not cause all flocks of oviducts not to develop, but there are some flocks of oviducts that are developed, undeveloped, and mature follicles in the body, less than normal or partially necrotic, so this part of the laying hens will have an egg every two or three days, which is a symptom of atypical branching.

2.Poisoning: In the process of development, the chicken flock ingests mildew serious feed, or ingestion of other toxic and harmful substances, may cause damage to the reproductive system, so that the fallopian tubes and ovaries are not well developed.

3.Infection with other viral diseases: In the process of development of the reproductive system, chickens are infected with viral diseases, such as influenza, and long-term fever will also cause imperfect development of fallopian tubes and ovaries.

4.Egg production is low at first, only 20%-30%, then slowly rises to 50%-60%, peaking at 91%-93%. When the laying hen reaches a peak of 80%-90%, there will be 2%-3% of double yolk eggs.

When the egg production rate decreases and egg reduction syndrome appears, a small number of soft and deformed eggs will be produced.

In short, there are many reasons why laying hens will lay eggs every other day when they just start laying, and they need to be analyzed in combination with the actual situation.

Under normal circumstances, it takes about 120 days for laying hens to see eggs from hatching, and the late ones are 130 days old.

1) Laying hens refer to chickens that are raised to lay eggs and lay eggs. Eggs are the main source of income for laying hens**. Unlike broiler chickens, the main issue with raising hens is to improve egg quality and maintain or increase egg production, not to improve chicken quality.

2) After decades of rapid development, China's layer industry has become the country with the largest egg production for 21 consecutive years. From 1980 to 2005, the annual growth rate of poultry egg production in China was, affected by the avian influenza epidemic, the growth rate has slowed down in the past two years, and the world is only in the same period, and the egg inventory and production in developed countries have basically remained stable, and there has been basically no growth in the past ten years.

3) In order to improve the people's living standards and stabilize the market, the "vegetable basket project" was proposed, mainly in pig production, laying hen breeding and other projects to give policy, financial support, etc., and in the suburbs of large and medium-sized cities to establish a large-scale large-scale layer farm, the scale of chicken farms ranging from tens of thousands to hundreds of thousands. After the 80s, with the implementation of the contract system of joint production in rural areas, grain output increased by a large margin, and the surplus labor force in rural areas continued to increase.

4) In order to meet the needs of the domestic market, domestic enterprises have introduced some excellent breeds of laying hens from abroad, such as "Xingza 288", "Xingza 579", "Ross chicken", etc., the introduction of these varieties has played a positive role in promoting the promotion of improved breeds in China.

The first egg may be seen in a hundred and several days, and disease, season, etc. will affect the laying time.

About 130-150 days old, the length of the light test time is determined. Eggs are laid earlier in summer than in winter.

<> generally laying hens can reach the peak of egg production in about 1-2 months after the start of production, and the specific time is related to feeding methods, layer breeds and environmental factors. Layer breeds should choose local chickens with strong physique, good egg quality, high egg production rate, strong disease resistance, strong foraging ability, tolerance to rough feeding and adaptation to the local environment.
