At present, most of the chickens are housed in open chicken houses. In the growing season, all-in and all-out systems are adopted, and most of them are raised on the net or raised on the ground.
(1) Temperature: 34 to 36°C in 1 to 2 day old brooders, 28°C in room temperature, 33 to 35°C in 3 day old brooders, and 28°C at room temperature; after 1 week of age, the number of brooders dropped in each week 2°C, 1°C lower at room temperature; 4 to 5 weeks old can be desorbed. During the warm-up period, the temperature is most likely to avoid cold and hot, so as not to cause a large number of chicks to die.
(2) Density: The breeding density is 30 to 40 per square meter during the incubation period, 15 to 20 per square meter at 12 weeks of age, and 7 to 10 per square meter after 12 weeks of age.
(3) Eating and Drinking: You can use chicken food directly, but it must be done after drinking. Drink water to ensure the quality of health, in the heat preservation period to feed the sterilized or filtered water. Since the broiler chicks are very susceptible to gastro-intestinal disease and affect the survival rate of brooding, gentamycin should be added to drinking water within 1 week of age, 1,000 international units per day per bird, only at the age of 2 weeks, 2000 international units per day. , 3rd week 3000 interstitial units/day. Only.
(4) Light: 0 to 7 days of age, 22 hours of light per day, 8 days of age to the first 5 weeks of age for 16 hours of light, 6-18 weeks of natural light, after the increase of 0.5 hours of light per week, increased to 28 The age of the week is 17 hours, and the light is maintained for 17 hours until 64 weeks. The light intensity is: 20 lux before opening and 40 lux later. Light must be evenly distributed.
(5) Grouping: Strong and weak grouping at each growth stage. After warming, male and female were reared in groups.
(6) Maintaining a quiet feeding and management environment: The chicken is active in nerve types. Any abnormal noise or foreign matter can cause the entire group to develop stress and run away. The screaming and fluttering, as in the laying period, can cause Egg production rate and hatching rate decreased. Therefore, all operations of the husbandry and management personnel must be regular so that the hens can produce good and familiar conditional reflexes, and actions should be light and not rude. The hen is light and has a certain ability to fly. Therefore, the fence of the playground outside the house should be 2 to 3 meters high.
(7) Chickens are susceptible to Marek's disease. Therefore, Marek's vaccine should be injected within 24 hours after hatching. Others, such as Newcastle disease and infected branch bronchitis vaccines, should be administered according to chicken immunization procedures.
(8) The broiler chicken does not need to be reared during the rearing period and does not need to be chopped. Because it is not easy to accumulate fat, it rarely fights or forms fleas, but it must supply nutritious feed.
(9) Chickens have higher requirements for constant and trace minerals and vitamins than chickens. In the daily feeding process, chickens increase about 8% to 13% more than normal chickens.
(10) Ladybirds do not require high levels of nutrients such as crude protein and energy for their diets. As long as they are fresh, the full price of the chickens can be maintained. However, because the chicks are small, the first week of age is for Chicken material is more appropriate, 2 to 3 weeks old chicken granule feed, after the size of the feed pellets should pay attention to adjust to avoid starvation and waste.
