The technology of how to raise white feather broilers

White feather broilers are characterized by fast growth rate, short feeding cycle and large average body weight at slaughter. Below I talk about the physiological characteristics of white-feathered broilers a few opinions.

First, the requirements of the house: in the northeast of the house insulation is the key, some farmers only pursue the quantity of breeding does not require quality, blind expansion of reproduction, poor houses, high labor intensity, high heating costs, chicken incidence and elimination rate. Therefore, the construction of chicken houses in Northeast China is very important, pay attention to the design of main insulation and vents. To achieve high quality breeding results. II. Brood: 50% responsibility for successful brooding of chickens, brooding temperature, humidity, air freshness in the house, density of chickens should be reasonable, temperature according to different seasons slightly different, but in line with a purpose, chickens do not gather without mouth breathing can, do not blindly stare at the thermometer, can not violate its physiological requirements; humidity control in 60-65%, appropriate humidity can prevent floating dust from entering the respiratory tract, resulting in the first vaccine after the nose, cough; Chickens ventilation can not be ignored, in fact, brooding period indoor heating fuel consumption of a lot of oxygen, after hypoxia, chicks will drink lead to non-pathological diarrhea or chick asphyxia death; density is too large to affect the uniformity of chicks poison and induce glandular gastritis, to timely transfer group. Third, the selection and use of vaccines: to select SPF eggs prepared vaccines, some vaccines are prepared with ordinary eggs, according to the epidemic characteristics of local diseases to develop immunization procedures. IV. Drug prevention and treatment: There are many misunderstandings in the use of drugs. Florfenicol is easy to immunosuppress. Cephalosporins should be used to treat Qi Yan and Gram-negative bacteria. Before 20 days of age, try not to use western medicine antiviral drugs, and use more pure Chinese medicine to prevent damage to the immune system. Medication should be used according to the course of treatment to prevent the occurrence of drug resistance, can not completely rely on drugs to prevent disease, to do a good job in environmental management, to create conditions suitable for growth, the probability of incidence is much smaller. Five, reasonable nutritional level: do not pursue the high and low cost of feed, nutrition balance quality can be stable, each manufacturer's feed production formula is slightly different, can not compare the amount of protein, and later need energy, so for concentrated feed, the increase is reduced (reasonable feeding cost, generally reduce the proportion of concentrated feed after 33 days of age, corn is the source of energy)
