Breeding of bred black bone chicken

Broiler chickens are typically raised from the 6th week of age until they reach the pre-harvest stage. For black-bone chickens, this period usually spans from 7 to 25 weeks. The quality of broiler management directly impacts their future egg production and breeding value, making it essential to focus on proper rearing practices. 1. **Staged Feeding** To meet the changing nutritional needs of broilers during different growth phases, feeding is divided into several stages. This approach adjusts feed composition according to temperature and developmental requirements, ensuring more efficient feeding and cost savings. Broiler diets are generally low in energy and protein, with some gluten and green feeds added to support gut development and improve digestion. This helps build a strong digestive system, which is crucial for long-term productivity. Additionally, feeding low-calcium diets during the rearing phase supports better calcium retention in hens, allowing them to maintain high egg production and shell quality once laying begins. 2. **Free-range Rearing** Free-ranging involves raising chickens in open areas such as barren hills, orchards, or bamboo forests. These environments provide ample sunlight, fresh air, and natural food sources like grass, insects, and small stones. After harvest, leftover grains and weed seeds can also be used to supplement their diet, reducing feed costs while improving overall health and growth. Free-ranging enhances physical fitness and breeding success, so it's encouraged wherever feasible. During free-range periods, chickens are often kept in mobile coops or cages, allowed to forage freely during the day and return at night. Initially, they should not be left too far from the coop until they become familiar with the area. It’s important to provide supplemental feed in the morning and evening, and using a sound cue can help establish a conditioned response for easier management. Clean water must always be available, and simple shelters should be provided to protect against weather and predators. 3. **Feeding Grit** Chickens lack teeth, so they rely on grit to grind food in their gizzard. Providing appropriate grit improves digestion and feed efficiency. Studies show that grit increases pellet feed digestibility by 10% and powder feed by 3%. The recommended amounts vary by age: 450g per 100 chickens for 7-10 weeks (1mm grit), 700g for 11-17 weeks (3mm grit), and 1,000g for 18-25 weeks (4mm grit). Grit should be clean and disinfected, either by washing or frying before feeding.
