Chicks are chicks of 0-6 weeks old. The chickens in this stage have poor adaptability to the environment, weak resistance to disease, slight maladaptation, and are prone to illness and death. Therefore, it is necessary to take care of the chicks during the broiler cultivation stage and carry out scientific feeding and management so as to breed chicks with fast growth and strong physique.
First, the brooding house disinfection and test temperature
1. Disinfection
(1) After the group is transferred, immediately clean, rinse, and sterilize the house and equipment, and empty the house for more than 2 weeks. (2) Use high-pressure water gun to flush from the top, walls, cages and ground. (3) Burn the wall, cage, ground, etc. with a flame spray gun. (4) Spray the wall and ground with 2% caustic soda first, and then rinse with clean water. After drying, use 0.2% hypochlorous acid or one hundred poisons to completely disinfect the chicken house and equipment. (5) Before the fumigation, close the doors and windows and put the brooding utensils into the house. Use 30 ml of formalin per cubic meter of space and add 15 g of potassium permanganate. After 24 hours, open the doors and windows to eliminate residual odor.
2. Test temperature
No matter which heating method is used, the temperature should be tested 2-3 days before entering the chicks. The temperature should be adjusted to 35°C to check whether the heating system is in good condition and whether the observation temperature is even and stable. Brooders and brooding sites meet the required standards.
Second, the grading, transportation and placement of chicks
1. Chicken grading and selection
The broilers are lively and vigorous, the hairs are bright, neat, uniform in size, and the birth weight meets the requirements of their varieties. Eyes are bright and responsive. Strong legs, strong legs and legs, standing firm. The abdomen is flat, soft, and the yolk absorbs well (not a large belly chicken). The feathers cover the entire abdomen, and the navel is dry and well-healed. Near the anus is clean, no white stool sticks. The cry was crisp and loud, and I felt full and vigorous in my hands and struggled vigorously. If the umbilicus has bleeding marks or red, black, brown or umbilicus, leg and tendon, eyes with disabilities, should be eliminated. Do not meet the requirements of the species but also eliminated.
2. Transportation of chicks
Use a dedicated chick box and place the chick box staggered when loading. Ventilation gaps should be left around the box, and the overlapping height should not be too high. The suitable temperature in the car is 23°C-26°C. In winter and early spring, it is better to leave at relatively high temperatures around noon. Observe every 2-3 hours to prevent the temperature from being too high, too low, and the back of the chick box falling down. Avoid traffic jams and bumpy road sections during transportation to achieve stability and speed.
3. Placement of chicks
After the chicks arrived, the chicks were placed on the ground and placed in an empty box. They were allowed to stand for about 15 minutes to allow the chicks to ease from the transport stress and to adapt to the temperature of the house. Then group and cage again.
When caged in groups, chicks are placed in cages according to planned capacity. According to the size of the chicks, separate placement. Poor chicks are placed in cages that are closest to the heat source and have higher temperatures. A few weak lying chicks are placed in a 35°C environment for special feeding and management. After 3-5 days of feeding and management alone, they are put into a large group after recovery. When caged, the chicks are placed in the middle two layers of brighter, warmer temperatures to facilitate management and then gradually evacuated to other layers.
