VII. Feeding and Management in Growing Period

This period is characterized by fast growth of chickens, strong appetite, and increased feed intake. At this time, the skeleton and internal organs are mainly formed. The purpose of feeding is to make the chicken body fully developed and full of feathers, laying the foundation for later fattening. Feeding methods are supplemented by grazing. Generally should pay attention to the following two points:

1. Feeding in groups. Common males have slower feathers, are more susceptible to environmental influences, and are more competitive. At the same time, they have a higher utilization rate of proteins and lysine in them, and thus have faster weight gain and higher feed efficiency. In addition, the roosters are strong and have strong ability to compete for competition. Because of the differences in endocrine hormones, the hens have a strong ability to deposit fat and thus have low weight gain and poor feed efficiency. The splitting of male and female parents, each listed on the appropriate day of age, facilitates the implementation of a breeding management system suitable for different sexes, which is conducive to improving uniformity and reducing the rate of defective products. During the whole growth period, regular feed supplements are used. The feed is placed in the bucket or directly on the ground, once in the morning and at night, until the net is full.

2. Deworming in time. After 20 to 30 days of general grazing, the insects were dewormed for the first time, and the insects were repelled for 20 to 30 days. Deworming mainly refers to the removal of parasites in the body, such as aphids and aphids. Can use flooding spirit, albendazole and so on. For the first time, each chicken was mowed with half a tablet and the second one. The tablets can be powdered in the evening at the time of oral or supper, mixed with a small amount of feed, and then fed together with the entire feed for dinner. Be sure to mix the drug and feed carefully, otherwise it is prone to drug poisoning. The next morning, check the chicken droppings to see if any of them have been excreted. Then remove the chicken droppings to prevent chickens from eating the insects. If there are adults in chicken dung, the next day can be the same amount of insecticide to kill insects once in order to completely remove the insects.

Eight, fattening period management

The fattening period is 10 weeks after the arrival of the market. The main points for feeding are to promote the deposition of fat in chicken body, increase the fatness of broilers, and improve the glossiness of meat and feathers. Management should pay attention to three points: First, with the increase in the age of broilers, from long bones, internal organs, feathers to long meat and deposited fat. The proper fat deposition of broilers can improve the meat quality of the chicken and enhance the aesthetic appearance of the carcass. Therefore, during this period, the metabolic energy of the diet should be increased, and the protein content should be relatively reduced. The energy level of the broilers during the fattening period is generally required to reach 12.54 MJ/kg, and crude protein can be about 15%. In order to reach this level, it is often necessary to increase animal fat. The second is to use grazing and fattening during the fattening period. On the one hand, chickens can eat nature's insects, leaves, grass roots, etc. to save feed; on the other hand, they can enhance the group's constitution and enhance the chicken's fleshy flavor, so that the appearance of the listed chicken, meat quality More adapted to the needs of consumers. However, during the fattening period, the venue should be reduced to reduce the movement of chickens. The third is to pay attention to insecticide, rodent control and cleaning and disinfection work. The mice both sneak feed and disturb the flock, but they are also the medium of disease transmission. Flies and mosquitoes are also the vectors that spread the disease. Therefore, it is required to kill mice 2 to 3 times a month. Frequent application of pesticides to spray mosquitoes, flies, fattening, inside and outside the environment of the shed, feeding trough, and tools should be cleaned and disinfected regularly to prevent the introduction of pathogens, targeted drug prevention and improved survival of fattening chickens. rate.

Nine, prevention and treatment of diseases

Although the disease resistance of chickens is strong, prevention and treatment of chicken diseases is also an important guarantee of success or failure. If there is no strict guarantee for health and epidemic prevention, in the event of a major epidemic disease, the death of chickens will increase, and the production of eggs will decrease and decrease. Benefits, even losses. While emphasizing the environmental sanitation of chicken farms, it is necessary to strengthen feeding and management, enhance the constitution of chickens, and increase the resistance to diseases of chickens. The chickens should be monitored for antibodies in a planned manner in order to determine the optimal timing of immunization and to check the effects of immunization. The vaccine used must ensure quality and the dose of immunization must be accurate and appropriate. To formulate scientific dosing procedures, it is advisable to give priority to prevention and prevent or reduce the incidence of disease in the chickens at a certain age or during climate change. In the event of illness, timely diagnosis and effective measures should be taken to control or extinguish the disease as soon as possible.
