The quality of chicks is the basis for broiler rearing. Only by purchasing good breeds and fleshy chicks can an ideal feeding effect be achieved. Ordering chicks should choose a parent breeder farm with a good reputation, a certain scale of production, good management and management, and obtaining a "special license for breeding livestock and poultry", and the condition of chickens in the farm (such as the age of chickens and laying eggs). Situations) and immunizations are fully understood. Excellent breeding farms should have no infectious diseases such as leukoplakia, mycoplasma, and flu. When picking up chickens, they should do a good job of picking young chicks, picking out cripples and weak chicks, and keeping strong chicks. Guard against the purchase of miscellaneous chicks, especially those that do not own hatchery plants.
Feeding methods
There are two kinds of feeding methods currently used to determine the feeding mode. One is feeding the ground litter and the other is the online raising. Which method is adopted depends on economic conditions and seasons. Adopting an online level raising program in spring, autumn, and winter can isolate chickens from feces, reduce the incidence of coccidia and E. coli, and reduce the amount of drugs used. Summer can be raised on the ground to facilitate cooling. Online feeding should pay attention to prevention and treatment of Staphylococcus disease, the equipment used should be smooth and thornless.
5 days before entering the chicks, the greenhouses were closed, cleaned, and the litter was laid out, and utensils, food troughs, drinking fountains, etc. were ready. First use 100 poison spray disinfection and then use Dex or potassium permanganate, formalin fumigation. In the brood chamber 1 to 2 days before the chicks were ignited to raise the temperature, open the windows, and keep the temperature of the brooding chamber at 25~30°C. The chicks slowly warm up after entering the greenhouse.
The chicks are allowed to drink warm boiled water for about 2 hours, and water-soluble electrolyzed multi-dimensional chicks and chicks can be properly added to the water. It is best to use pellets to start food.
The feeding of commercial broilers is generally divided into two stages according to the growth stage. The pre-stage (1 to 4 weeks old) nutritional requirements: metabolic energy 12.55 MJ/kg, crude protein 22%, calcium 1%, phosphorus 0.6%. In the later stage (5 to 7 weeks old), the nutritional requirements are: metabolic energy 12.97 MJ/kg, crude protein 20%, calcium 0.9%, and phosphorus 0.5%. When selecting feed, you should not only consider the price. You should focus on the quality. You can carefully understand the use of other chickens. Feed must prevent mildew and storage.
Focus on the management of the uniformity, according to the size of the weight of timely grouping and transfer groups to ensure the development of the group evenly, easy to focus on sale.
Use the 23h light in the first week, then you can turn on the lights after 24h light, intermittent light (take 3h, stop for 2h) or after 12:00 in the evening, and feed the chicken from 5:00~6:00 in the morning so that the chicken has enough time to rest.
Every morning, when the material is added, the remaining material should be cleaned. If there is more, it will not be added after eating. Feeding in the morning and evening can be done in summer. When the appetite is poor, 2% garlic can be added to properly compound VB.
Day-to-day management work is done with six observations and one isolation, that is, whether the attitude of observing chickens is abnormal or not; secondly observe the degree of fluffiness and luster of feathers; three observe the number, color and status of defecation; four observe the respiratory status; five observe the amount of feed and drinking water; , Six observe the growth of chickens. Through the daily observation of timely detection of sick chickens, the implementation of isolation and timely drug treatment. The chickens should be regularly disinfected to reduce the incidence of death and increase the economic efficiency of raising chickens.
In order to improve the growth in the later period, you can add oil to the feed. The broilers are 30 days old, first add 0.5%, and slowly transition to 2%. Chicks can not be added too much, so as to avoid excessive energy, excessive growth, ascites and sudden death.
