Broiler fast-feeding

First, choose a good broiler breed. Under the local production conditions, strictly follow the broiler rearing technical measures formulated by the Bureau of Animal Husbandry. Second, strengthen management. For chickens, open-land flat-feeding, free-feeding, and all-in and all-out methods are used. For the first batch, especially the second and subsequent batch-by-batch chicks, the wall, floor, feeding utensils, and litter must be thoroughly disinfected according to the disinfection operation rules before the chicken house is introduced. The litter should be timed. replace. After the house is sterilized, it should be idle for 1-2 weeks, and then the chickens should be brought into the house for rearing. Third, scientific feeding. For broilers, feeds are adjusted according to different ages. No. 1 pellet feed is fed from 1 to 8 days; No. 2 pellet feed is fed from 19 to 35 days; No. 3 pellet feed is fed after 35 days and fed until 45 days of age. Achieve standard bodyweight slaughter. Fourth, the appropriate density, temperature, humidity. 1. Density: 8 to 10 can be raised in 1 square meter in summer; 13 in 1 square meter in winter and spring; 400 to 500 broilers are housed in 35 square meters of houses in rural township chicken farms. 2. Temperature: In the first week, the oysters are burned and the stove is warmed. The oysters are raised on the fire quail. After 7 days, they can be raised to the ground. A layer of sterilized sawdust is placed on the fire bowl and the ground. The indoor temperature should be 32°C-34°C. It is advisable to use the temperature before the chicks enter the house as the initial brooding temperature. Indoors should always be well ventilated, dry and clean. 3. Humidity: The relative humidity in the house should be maintained at 60%-70% and the young bird should be maintained at 50%-60%. In order to keep the house dry and the humidity is suitable, drinking equipment should be placed in a suitable location. Fifth, adequate lighting. Regardless of the kind of chicken house, it takes 23 hours of light. The first week requires strong light. It is advisable to install a 2-3 watt light bulb per square meter of chicken house. After that, the lamp wattage per square meter can be appropriately reduced to facilitate chicken lighting. Six, pay attention to ventilation. The ventilation is to ensure that the indoor air is fresh. Because of the high body temperature of chickens, the maximum ventilation volume is 4.5 cubic meters per kilogram of body weight per hour, and the amount of ventilation in summer is about four times that of winter. Therefore, a Ventilator should be provided when building a chicken house to facilitate the regulation of indoor air. Seven, adequate drinking water. Use a vacuum waterer to replace the vacuum waterer with a wide-mouth bottle and a shallow dish. Use a small wooden stick under the bottle to allow water to flow out of the gap. Eighth, do a good job of epidemic prevention. The timely inoculation of broiler chicken Newcastle disease L-type attenuated freeze-dried vaccine seedlings, the general first immunization should be carried out at 7-10 days of age. The second immunization is performed 25-30 days apart. All chicken farms use two kinds of immunization methods: one is nasal instillation method, use distilled water or cold water to dilute the vaccine 10 times, use a sterile pipette to draw the vaccine, and instill two drops into the nostrils, each drop is about 0.03 - 0.04 ml; the other is the use of drinking water immunization, according to vaccine instructions, dilute the vaccine into the drinking fountains. In order for each chicken to drink vaccine water, the chicken must be controlled for 4 hours in advance. Under the premise of lack of water, the chicken can drink enough vaccine water to achieve the effect of immunity. This method is very effective. Suitable for large chicken farms.
