The main raw materials for the winter fermentation bed are sawdust, straw and straw. The straw or straw is first cut to a length of 10 to 15 centimeters. The thickness of the fermentation bed is 30 centimeters.

Chicken house management

(1) Do a good job in the ground management of chicken houses: 125 chickens are raised in a chicken house (25.6 square meters). The moisture content is often kept at 65%, and the ground is easy to dry from April to November. The ground was turned once every two weeks. At the same time, a 100-fold dilution of the EM broth was used to produce a good environment for the fermentation bed strains. When fertilizer is needed in the spring, half of it is used as fertilizer, and the other half allows the microorganisms to continue to expand. After the fertilizer is released, it fills in new straw and EM broth used in the fermentation bed; there is no need to use fertilizer for 2 years and 3 years. This is beneficial to the healthy growth of chickens, but also can extend the egg production period. Because chickens lick the ground and eat microorganisms and minerals, they can supplement protein feeds and various trace elements.

(2) Pay attention to ventilation management: In the spring, summer, and autumn seasons, ventilators and sunroofs are often ventilated according to the use of the south and north sides. Not only do you need to do a good job of insulation during the winter, but also open the skylights during the day to discharge the contaminated air and water and reduce the relative humidity. .

(3) When the chicks reach the 50-60th day of the month, the Yasuji and Persian should form a bow with a slightly higher height in the middle. The entire front of the perch is low and the back is high. Such a perch can ensure that the chickens are not crowded. Quiet break. In normal circumstances, healthy chickens occupy high places and weak chickens take up the place.

(4) The nest box starts from chickens on day 140 and puts them in the chicken house. The chicks are familiar with the nest box, and the laying floor is laid on the ground to make the chickens lay eggs and eat rice. At the beginning, it was necessary to make the box light up to eliminate the sense of chicken terror. Later, the box was gradually darkened and blackened with black cloth.

(5) feed trough to the direction of the sink, a straight line four, disease prevention and control 1 must adhere to the "prevention, treatment, supplemented by" principle, and actively take preventive measures to control the occurrence of the disease. The illness was not born but was recruited. If the body is healthy, the disease cannot occur. After taking the disease, medication is used to prevent the disease from worsening. Treatment is the body's own business.

According to the above principle, in order to eliminate the cause and restore vitality, the spring and new nutrients, spring and spring bacilli, lactic acid bacteria, and rice vinegar are used to maintain the health of the chicken. Use spring new nutrient and spring new bacteria liquid to sterilize chicken house ground regularly. Chickens that grow in fresh air, adequate sunlight, and moderate temperature and humidity need little health care.
