Breeding techniques of Iron-footed Ma Chicken

Iron foot hemp chicken belongs to meat type poultry, the back feather surface of hen is mainly ephedra, hemp brown, hemp brown three kinds of color, rooster physique is strong, the structure is symmetrical, the breeding range is mainly distributed in Sichuan, Chongqing, Yunnan, Guizhou, Guangxi and other places. In recent years, after independent cultivation and breeding in various farms, its growth gene has changed a lot. Let's take a look at the breeding technology of Tiejiao chicken.

Feed management

Iron-footed hemp chickens can be raised freely and feed freely. The crude protein of the diet is required to be 1819%, and some green vegetables or grass can be fed in the later stage, accounting for about 20% of the total feed, but they are not mixed with dry fodder. After 30 days of age, if breeding chickens are kept, quantitative feeding is used to prevent precocity and overfattening. Each group of breeder chickens can raise 100,200 chickens, and they can be fed with green fodder 4 times a day. According to relevant experts, it is best to plant green forage grasses with rich nutrients and good appetite, which are rich in protein and calcium. Farmers should mainly plant some legume forages such as hn-mc excellent alfalfa and hn-mc you Sha Tawang, which can be cut and fed in a tender period.

Ventilation and ventilation

Iron-footed chicken should also pay attention to ventilation in feeding. In the case of low temperature in deep winter, people often only pay attention to warmth and ignore ventilation. When the air in the house is relatively dirty in the morning, the ventilation volume should be gradually increased, preferably when the temperature is higher at noon, and it is better to use a shorter ventilation time each time and several more times. If it is found that the chicken is disease-free and wilting, breathing slightly, and the chicken house is filled with dust and strong smell, it means that the air in the chicken house is extremely dirty and should be ventilated immediately. However, in order to prevent the thief wind, the leeward wall of the chicken house is generally equipped with elbow-type ventilation to prevent the chickens from being directly affected by the wind.

Disinfection of chicken farm

When raising iron-footed hemp chickens, drugs should be properly used to disinfect the environment, and the henhouse should be fumigated with potassium permanganate and formalin for air fumigation for 8 hours and 10 hours. After fumigation and disinfection, leave a vacancy period of at least 1 week. It takes 30 minutes to disinfect drinking water with bleach, and it takes only 15 minutes to add 5-6 drops of 2% iodine tincture to each kilogram of drinking water. The use of peracetic acid spray disinfection usually takes 10 to 20 minutes, and if fumigation is used, it will take 1 to 2 hours. When disinfecting feces with lime milk, the contact time between lime milk and feces should be at least 2 hours.

Disease and epidemic prevention

The prevention and treatment of diseases in the breeding process of iron-footed hemp chicken runs through the whole breeding process, and the hatched chicken should be injected with Marek's vaccine. Chicks at the age of 1 to 5 days, 12 to 14 days of age, ill and poorly managed, were administered once at the age of 35 to 37 days, each time for 3 to 5 days, to prevent bacterial diseases such as salmonella and Escherichia coli. Enrofloxacin was the first drug to drink for half a day with 100 milliliters of 10% solution dissolved in 100 kg water, or 10 mg per kg body weight. In addition, Tylosin (tylosin), doxycycline and other drugs are used to prevent respiratory diseases such as mycoplasma and mycoplasma, and drinking water is often disinfected with disinfectants such as permethrin. Pay attention to the prevention of coccidiosis before and after 3 weeks. At the age of 7-10 days, the chickens were given Newcastle disease II vaccine by nasal drip or drinking water, and were vaccinated with fowlpox vaccine. At the age of 12-14 days, the chicken bursa vaccine was first immunized with drinking water, and it was best to strengthen it again two weeks after the first immunization. Breeder chickens should do a good job in vaccination and prevention of inactivated oil vaccines such as Newcastle disease, bursa of Fabricius and infectious bronchitis, which should be formulated according to the immunization procedures of local domestic chickens.
