Management Technology for Broiler Chickens in Greenhouses
The management technology for broiler chickens in greenhouses is provided by the 5830 Agricultural Website Directory:
Broiler Rearing Methods
The current rearing methods include two types: one is ground bedding rearing, and the other is online flat rearing. The choice of method depends on economic conditions and season. Online flat rearing is recommended in spring, autumn, and winter as it separates the flock from feces, reducing the incidence of coccidiosis and E. coli, and minimizing medication use. In summer, for easier cooling, ground rearing can be used. For online rearing, care should be taken to prevent staphylococcus disease, and the equipment used should be smooth without any sharp edges.
Purchase High-Quality Chicken Chicks
The quality of chicken chicks is the foundation of broiler farming. Only by selecting good varieties and quality chicken chicks can ideal farming results be achieved. When ordering chicken chicks, choose a parent generation breeder farm with good reputation, a certain production scale, good management, and a "Breeding Livestock Operation License." Gain a comprehensive understanding of the flock's status (such as the age of the breeder chickens, egg-laying situation) and immunization status. An excellent breeder farm should be free from infectious diseases such as white diarrhea, mycoplasma, and influenza. During chick reception, carefully select the chicks, separating out weak or defective ones and retaining only strong chicks. Be sure to avoid purchasing inferior mixed chicks, especially if you do not have your own hatchery.
Prepare for Brooding
Five days before introducing the chicks, tidy up and seal the greenhouse, clean it thoroughly, lay down the bedding, and prepare all necessary tools, feed troughs, and waterers. First disinfect using a spray of Baidu Kill, then fumigate with Dekes or potassium permanganate and formalin. One to two days before introducing the chicks, light a fire to increase the temperature in the brooding room and adjust the windows, maintaining the brooding room temperature at 25~30℃. After the chicks enter the greenhouse, gradually increase the temperature.
Watering and Feeding Broiler Chickens
After resting for about 2 hours, the chicks can drink warm water. Electrolytes and vitamins can be added to the water, along with chick-friendly supplements. It is best to use granular feed for the initial feeding.
Nutrition in Broiler Chicken Feed
Feeding commercial broilers generally divides into two stages based on growth phases. The first stage (1-4 weeks old) requires metabolic energy of 12.55 MJ/kg, 22% crude protein, 1% calcium, and 0.6% phosphorus. The second stage (5-7 weeks old) requires metabolic energy of 12.97 MJ/kg, 20% crude protein, 0.9% calcium, and 0.5% phosphorus. When choosing feed, don't just consider price; focus on quality and understand the feed usage of other chicken farmers. Prevent feed from becoming moldy or stored for too long.
Observe the Flock
Daily management involves six observations and one isolation: observe whether the chicken behavior is abnormal; observe the fluffiness and luster of the feathers; observe the quantity, color, and state of the feces; observe respiratory conditions; observe feed and water intake; and observe the growth of the flock. Through daily observation, promptly identify sick chickens, isolate them for feeding, and administer timely drug treatment. Regular disinfection should be conducted to reduce disease and mortality, thereby improving poultry farming economic benefits.
Empty Feed Troughs
Every morning when adding feed, clean up any leftover feed. If there is a lot left, wait until it is finished before adding more. In summer, feed in the early morning and evening, providing small portions frequently. When appetite is poor, add 2% garlic and appropriate amounts of complex VB.
Lighting
Use 23 hours of lighting in the first week, then switch to 24-hour lighting, intermittent lighting (light for 3 hours, off for 2 hours), or turn off lights after midnight and feed between 5:00 AM and 6:00 AM to allow chickens sufficient rest time.
Group Separation
Focus on managing uniformity by appropriately grouping chickens according to weight size, ensuring even development within the group, which facilitates concentrated sales.
