CATDOLL : CATDOLL: What causes laying hens to drop eggs? Can laying hens that are fed wet corn recover from dropping eggs?

What happens when laying hens drop eggs?

1. Feeding and management factors

1. Inadequate environmental work and disinfection work in the chicken house can easily lead to bacterial growth, causing the reproductive organs to be invaded by bacteria for a long time and causing diseases, thus affecting the egg production rate of laying hens;

2. Excessive stocking density will make it difficult to reach the weight standard, which will directly affect the brooding, egg production rate and quality of the chickens;

3. Poor ventilation causes the air in the chicken house to be dirty and the ammonia smell is too strong. Living in such an environment for a long time will cause the chickens to be in a state of disease, which will seriously affect the growth and development of the chickens and the egg production rate of laying hens;

4. The effective position of the feed trough and waterer is not enough, which results in the chickens having to take turns to drink water and eat feed, resulting in insufficient nutrition for the chickens, which will cause a decline in the quality and uniformity of the chickens, and will also be accompanied by a decline in egg production rate;

5. The lighting is unstable or the light intensity is insufficient. Under normal circumstances, laying hens need about 16 hours of light a day to meet the peak egg-laying period. Unstable light or insufficient light intensity will have a certain impact on the egg-laying rate of the flock. When supplementing light, the lights must be turned on and off on time and cannot be changed at will.

2. Nutritional factors

1. Incomplete nutrition: The nutrition of laying hens is the primary condition to ensure the egg production rate of the flock. If the nutrition is low, the high production requirement cannot be achieved. If sufficient calcium and protein are not supplemented in time after the start of laying, egg dropping will also occur.

2. Feed mold: Moldy feed not only reduces nutritional quality, but also contains toxic substances that affect the health of the chickens. Therefore, fresh feed should be fed and a de-mold agent should be added to the feed.

3. Frequent feed changes: When changing feed, the transition needs to be gradual. Remember not to change it directly or change the feed too frequently, which will cause stress to the chickens and cause egg dropping.

3. Disease Factors

1. Infectious diseases: latent infection of certain diseases, such as improper immunization of Newcastle disease before laying hens start laying eggs, which may cause latent Newcastle disease in chickens, or frequent neglect of disinfection of chicken houses, which may also cause the presence of Escherichia coli disease; mild influenza, infectious bronchitis in chicks, etc., often cause serious damage to the reproductive system;

2. Salpingitis and oophoritis: These diseases are the most direct cause of egg loss, and are most likely to occur in farms with poor breeding environments and inadequate disinfection. In normal times, you should pay attention to the use of anti-inflammatory drugs for prevention.

IV. Other factors

1. Drug poisoning: There are contraindications for laying hens, especially in disease prevention or treatment. For example, sulfonamides and sulfonamide enhancers, aminophylline, chlortetracycline that affects calcium ion synthesis and other drugs can cause irreversible damage to the reproductive system, etc.

2. Breed factors: Poor quality chicks often drop eggs during the egg-laying period, so it is crucial to choose high-quality chicks;

3. Unreasonable arrangement of the peak egg-laying period: The egg-laying peak of laying hens is generally at 25-35 weeks of age, and the egg-laying rate can generally reach more than 85%. Entering the peak period too early or too late will cause laying hens to drop eggs;

4. Different batches of chickens enter the same chicken house: Different batches of chickens have different ages, and the feeding management, disease prevention and control measures, and different lighting systems have significant differences in egg production. Following the same feeding method will not only cause egg dropping, but in serious cases, it will cause the entire house to lose its peak.

Can laying hens recover from dropping eggs after being fed wet corn?

It can be restored, but first you have to stop feeding wet corn. Secondly, give some intestinal anti-inflammatory and intestinal mucosal repair products. Wet corn has a great impact on the chickens. The mycotoxins it breeds are difficult to treat and can also damage the liver and kidneys. I suggest you use nystatin tablets, cod liver oil and multivitamins, as well as egg-increasing drugs. Antiviral drugs are also necessary when necessary.
