Lingnan Yellow Chicken Breeding Management Technology
To ensure the success of raising Lingnan yellow chickens, it's crucial to focus on several key aspects from the very beginning. First and foremost, the quality of the chicks is essential. Currently, only the Poultry Research Institute under the Guangdong Academy of Agricultural Sciences provides authentic Lingnan yellow chickens. However, many counterfeit versions are sold in the market, often at a lower price but with poor quality. When purchasing day-old chicks, make sure to select those with proper characteristics such as good growth rate, feather development, coat color, body shape, and accurate sex identification. Also, ensure that they have been properly vaccinated against Marek’s disease.
Next, transportation plays a vital role in the health of the chicks. Healthy chicks should be moved to the brooding house within 6 to 12 hours after hatching. If transporting over long distances, the time should not exceed 48 hours. Chicks left for more than 48 hours may suffer from hunger, dehydration, and weakened immunity, leading to higher mortality. In summer, it's best to transport them in the evening to avoid heat stress. During winter, insulation is critical to prevent cold exposure.
The survival rate of the broodstock is significantly influenced by the breeder's experience and management skills. A knowledgeable breeder who takes responsibility for the flock can greatly improve the overall performance and survival rate.
Preparation for brooding is also essential. Before bringing in the chicks, thoroughly clean and disinfect the sheds and all equipment. The area can be fumigated using 30 ml of formalin and 15 g of potassium permanganate per square meter, left to fumigate for 24 hours. Equipment should be soaked in a disinfectant solution, then dried in the sun. Litter, usually made of fine wood shavings or sawdust, should be 8–10 cm thick and disinfected before use. It's also important to have antibiotics and disinfectants ready for use.
When the chicks arrive, allow them a short rest before offering water. Adding 1% glucose or vitamin B to the water helps replenish their energy. Water temperature should be around 18–24°C, and if it's cold, preheat the water or warm the house. Provide one drinker for every 80–100 chicks during the first few days, increasing the number as they grow. Feeding should start about two hours after drinking. Use high-quality feed, spread evenly on trays or paper, and gradually transition to feed buckets after a week. Free-choice feeding reduces the need for frequent feeding.
Temperature and humidity control are crucial for brooding. For commercial broilers, the ideal temperature is around 20°C. Too low or too high temperatures can affect feed intake and weight gain. Chicks with small body size or those with large yolk sacs require slightly higher temperatures. In winter, increase the temperature by 1–2°C compared to summer, and raise it further at night. On the first day, maintain a temperature of 33–35°C, then decrease it by 0.5°C daily until reaching 20°C. Monitor the flock’s behavior—healthy chicks will be active, eat well, and sleep peacefully without signs of distress.
Feeding density also affects chick growth and uniformity. Overcrowding leads to poor ventilation, uneven feeding, and slower growth. For Lingnan yellow chickens, it's recommended to keep 30 chicks per square meter for the first 14 days, 15 per square meter for days 15–28, and 10 per square meter for days 29–49. Ensure there is enough space for feeding and watering, ideally about 8 square meters per group.
Lingnan yellow chickens are generally calm and do not fight. Beak trimming is typically done at 20–25 days old, cutting only 1/3 of the beak. Two days before trimming, add complex vitamins or vitamin K to the drinking water to reduce stress.
Finally, disease prevention is essential. Implement a "all-in, all-out" system and maintain clean feed and water. Observe the flock daily for any signs of illness, and isolate sick birds promptly. Keep detailed records of chick numbers, health status, medication, and vaccination. Vaccination schedules should follow a proper protocol to ensure maximum protection.
Vaccination Schedule for Lingnan Yellow Broilers:
Day 1: Marek’s vaccine (subcutaneous injection in the neck)
(Additional vaccines may be added based on local disease prevalence and farm conditions.)
