Raising Technique of Green Shell Layer

Chicken and eggs are common poultry products at our dinner table. With the strengthening of people's awareness of health, the requirements for pollution-free and green food are getting lower and lower. As for chicken farmers, it is urgent to know if they raise green chicken products and reduce the cost of raising them. Let's follow the editor to learn about the feeding techniques of green-shell laying hens.

1. Chicken house construction

The chicken house should be ventilated to the sun, with a daylighting window every 3 meters before and after, and a perch, drinking fountain and material trough can be placed on one side of the room. On the other hand, a small door is opened on the sunny side, and there is a sports area covered with sand outside the door to ensure that the chickens have plenty of room for activity.

2. Incubation

When hatching, eggs of more than 40 grams should be selected as breeding eggs, artificial hatching technology should be adopted, eggs should be hatched at constant temperature in batches, and attention should be paid to cross intervals. In the first 18 days, 37.8 degrees should be maintained in winter and 37.5 degrees in summer. Turn in the chicken on the 19th day, pay attention to flat, the temperature should be kept at 37.2 degrees in winter and 37 degrees in summer. Turn the egg every 2 hours, the angle is 90 degrees, it can be shelled on the 21 day, and the shell is basically finished in 20 days. Disinfect the eggs before hatching and 30 minutes after birth to ensure the healthy growth of breeding eggs and chicks.

3. Feeding

The growth stages of green shell laying hens are different, and their feed nutrition levels are also different. the general diet crude protein accounts for 20%, the young chicken crude protein accounts for 15%, and the breeder crude protein accounts for 17%. The chick is in the breeding period within 30 days after it comes out of the shell, and the most important thing at this time is to keep warm. It should be kept at about 33 degrees within three days, and then decrease by 2 degrees every other week. It is necessary to drink water before eating, and feed full-price chicken feed 4-6 times a day. At the same time, the breeding room should pay attention to ventilation and gradually reduce the feeding density with the increase of age.

4. Disease prevention and treatment

Disease prevention and treatment runs through the whole feeding of laying hens, especially the prevention of bacterial diseases such as Monella and Escherichia coli. The first drug is enrofloxacin, which can be added to drinking water. Letting chickens drink freely can prevent these two kinds of bacterial diseases very well. In addition, drugs such as tenosin and doxycycline are used to prevent respiratory diseases such as mycoplasma and mycoplasma. Chicken coccidiosis should be prevented before and after 20 days of age, and Newcastle disease vaccine and fowlpox vaccine should be given at 7-10 days of age.
