What's happening at the slow peak of egg production in laying hens

In autumn, many farmers in Shandong Province generally reflected a problem. In the recent period of time, the production of chickens was started later than usual, and the peak time was relatively long. Generally, 130 days of production is required before they can start production. The egg rate has risen very slowly and is expected to reach a peak one month later than the chickens opened in spring and summer. There are many reasons for the slow peaks in laying hens. The author summarizes several main reasons based on his years of work experience and shares with you.
Dysplasia of the flock resulted in a large number of small, thin, poorly-crowded or over-obese chicks.
Weight is closely related to the production performance of chickens and is an external indicator of chicken health status. In other words, whether or not the body weight of the chicken meets the criteria directly determines the rate of egg production, the length of the peak period of egg production, and the resistance to diseases. In particular, the body weight before 8 weeks of age, if not up to standard, will cause irreparable loss for future production performance.
The main causes of chickens not achieving their body weight include: low feed nutrient levels, poor quality, high stocking density (insufficient feed intake and drinking water tanks), poor environment, and illness, etc. In addition, uneven body weight is the result of the above reasons.
As a management priority, regular weighing will help the farmer monitor the weight of the chicken and take measures as soon as possible if there is a non-compliance.
Natural light patterns and changes in solar terms It is well-known that chickens do not supplement light during the breeding period. The chicks in the middle to late September and early April of the following year are in a period of prolonged sunshine from 10 weeks to 20 weeks of age. The chicks born from mid-late April to early September are 10 weeks to 20 weeks old. At the time of age, it is at a time when the sunshine is gradually shortening. From 10 weeks to 20 weeks of age, the reproductive system of the chicken is gradually sensitive to light. The chicks born in summer and autumn have a much slower development of the reproductive system than the chicks born in the winter and spring. It is also appropriate to start production later. 7 days to 10 days.
Illumination is irrational. If the time is too short, the light is too weak, or the time for opening and closing the light is irregular, it can also cause the production of eggs to rise slowly.
The feed used has low nutrition and cannot meet the demand for high-yield, resulting in low reproductive function and easy to stop production. For example, during the peak period of chicken egg production, the lack of methionine and cystine, the improper or insufficient proportion of mineral salts, insufficient supply of trace elements and vitamins, and the use of new corn with high moisture content, resulting in lower energy content in feed; using quality Non-compliance of soybean meal results in lower protein content in feed. These reasons can cause the chicken group to weigh less than the body weight, body resistance decreased, easy to stress fried group, slow growth, etc., will affect the rise of its egg production curve.
In the case of diseases, chicks had infectious bronchitis, bird flu, etc., which caused severe damage to the reproductive system, or poorly developed reproductive system. At this time, the chickens were normal in appearance, but there were many birds with small, pale, or shrunken crowns. At the necropsy, there was no development of the fallopian tubes or sparse follicles.
After the start of production, chickens reach the peak of egg production, and are infected with chicken flies, respiratory diseases, egg drop syndrome, atypical Newcastle disease and other diseases, or there are chronic diseases or subclinical subclinical diseases such as coccidia or parasitism. Intestinal poison syndrome caused by insects, etc., can cause the eggs to rise slowly in the flock.
The impact of stress on feeding time, frequent changes in feed formulations or raw material varieties, stopping feed water, sudden changes in temperature, etc. will all result in low egg production.
Summarizing chickens to earn money requires long-term benefits. This requires farmers to do their daily feeding and management work to provide chickens with a high-quality feed that is comprehensive and can improve body resistance and prevent intestinal diseases.
