When do chickens lay eggs? What are the key points to pay attention to during the peak laying period?

For raising chickens, especially laying hens, the length of the peak laying period determines the interests of farmers. In the stage of 43-126 days, if the light is not limited, the chicken will lay eggs ahead of time, resulting in a peak laying period of 3-5 months, causing serious losses, in order to avoid keeping 8 hours of light during this period. Feed restriction, during the period of 127 to 150 days, the feed must be limited and brightened, because chickens do not lay eggs at this stage. If you provide high-energy and high-protein feed, not only the cost will increase, but also the "pot-bellied chicken" will appear because of excess energy, which will affect the laying rate of the peak period. The loss outweighs the gain, so after the feed restriction, the light will be gradually extended from 8 hours to 16 hours.

It takes 21 days for a fertilized egg to hatch, 28 days for a duck egg, 30 days for a goose egg, 18 days for a pigeon egg, 26 days for a pearl egg and 27 days for a turkey egg. A chick needs to go through these stages from hatching to final elimination. Roman powder for example: 1: 42 days is the breeding period, 43-126 days is the breeding period (8 hours of light, delaying the peak of egg production), 127-150 days is the breeding period (limited feed, light, reduce feed cost), 151-180 days is the egg-laying rising period, also called head egg, the laying rate is 85%, 181-480 days is the laying peak, the laying rate is 95%, 16 hours of light is satisfied, and the laying peak is after the laying peak. The laying rate has decreased significantly, so molting or sale should be considered.

The peak period of egg production is so important, what should farmers pay attention to?

1. In addition to daily management, pay more attention to the condition of laying hens. Usually, in addition to picking up eggs, clearing dung, feeding, and cleaning, we should also observe the state of laying hens to see if there are any chickens with diarrhea or dishevelled feathers. when it is quiet at night, listen to whether any chickens are sneezing, coughing and so on. In short, observe and pay more attention. Layers must keep up with their nutrition. It is recommended to use a full-price formula feed rich in minerals and vitamins that is high in energy and protein.

two。 Reduce stress and maintain environmental hygiene. High-yield laying hens are easily frightened, especially when children set off firecrackers or car sirens, resulting in low feed and low laying rate. Farmers should also be careful not to change materials frequently, cut off water and light, catch chickens, wear brightly colored clothes to enter the henhouse, and maintain the national temperature, humidity, light, personnel and so on. Disinfect the chicken house with disinfectant regularly, clean or scrub the material trough and sink regularly to prevent the growth of pathogens.

3. Summer chicken need to pay attention to: the best temperature for chicken adaptation is 13-25 degrees, production is used to use 21-25 degrees, in the hot summer, feeding chickens mostly in the cool morning. In terms of diseases, follow the immunization and health care procedures of the chicken farm, and pay more attention to the occurrence of epidemic diseases, especially bird flu. Ventilation, ventilation, moisturizing, cooling, sanitary disinfection, summer stress reduction can add 0.02% vitamin C to the feed or water of laying hens.
