Breeding techniques of White Feather Chicken

White-feathered broiler is characterized by fast growth, short feeding cycle and significant average body weight. China's white-feathered broiler industry, which started in the 1980s and after nearly 30 years of efforts, has become the fastest and most typical industry of agricultural industrialization in China, and is one of the three largest producers of white-feathered broilers in the world. Chicken products have become the only industry in China that can export a large number of meat products to earn foreign exchange. Over the past 20 years, the production of white-feathered broilers has continued to grow at an average annual rate of 5% to 6%.

The requirements of the premises

The heat preservation of houses in Northeast China is the key. Some farmers only pursue the quantity of breeding and do not require quality, and blindly expand reproduction. The houses are poor and poor, resulting in high labor intensity, high heating costs, high incidence and elimination rate of chickens. Therefore, the construction of the chicken house in the northeast is very important, pay attention to the design of the main heat preservation and ventilation. In order to achieve high-quality feeding performance.

Brooding

Whether the chicken is raised successfully or not has 50% responsibility. The temperature, humidity, the freshness of the air in the house and the density of the chicken should be reasonable during the breeding period. The temperature varies slightly according to different seasons, but for one purpose, the chicks can not gather together and breathe without opening their mouths. Do not blindly stare at the thermometer, can not violate its physiological requirements. The humidity is controlled at 60-65%, and the appropriate humidity can prevent floating dust from entering the respiratory tract, resulting in nose swinging and coughing after the first vaccination. The ventilation of chicks cannot be ignored. In fact, a lot of oxygen is consumed for indoor heating during the breeding period. After hypoxia, chicks will drink heavily and cause non-pathological diarrhea or suffocation death; too high density will affect the uniform toxin of chicks and induce glandular gastritis.

Selection and use of vaccines

To choose vaccines made from SPF eggs, some vaccines are made from ordinary eggs, and immunization procedures are developed according to the epidemic characteristics of the local epidemic.

Drug prevention and treatment

There are many misunderstandings in the use of drugs. Florfenicol is easy to be immunosuppressed. Cephalosporins should be used to treat both inflammatory and Gram-negative bacteria. Before the age of 20, try not to use western antivirals, and use more pure traditional Chinese medicine to prevent damage to the immune system. Medication should be used according to the course of treatment to prevent the emergence of drug resistance, can not completely rely on drugs to prevent disease, to do a good environmental management, to create conditions suitable for growth, the incidence of the disease is much less.

Reasonable nutrition level

Do not pursue the level of feed cost, nutrition full-price balanced quality can be stable, each manufacturer's feed production formula is slightly different, can not compare with each other, early feeding needs protein, and later needs energy, so for concentrated materials should be added and reduced (reasonable feeding cost, generally reduce the proportion of concentrated materials after 33 days of age, corn is the source of energy).
