1. Intensive brooding and careful feeding

In order to improve the survival rate of the young chicken, Zheng Silu made full preparations for raising the brood before entering the chicken. The temperature of the nursery room was set to 30 ℃, and the husband and wife took turns on duty. The performance of the young chicken was observed every 2 hours and fed a feed. Due to careful breeding and scientific management, the survival rate of young chickens is more than 94%.

2. Formulate immunization procedures and implement planned immunization.

Whether raising chickens can be beneficial, the survival rate is the foundation, and epidemic prevention is the key. Zheng Silu worked out the immunization procedure according to the characteristics of his ecological culture. After coming out of the shell, the young chickens were injected with Marek vaccine, Newcastle disease vaccine was given intranasally on the 8th day, bursa vaccine of Fabricius was dropped into the eyes on the 10th day, inoculated with fowlpox vaccine on the 16th day, drinking water again on about 50 days, and Newcastle disease vaccine was injected into the muscle on the 60th day.

3. Carry out ecological breeding and provide green products

In order to ensure the quality of broilers and provide green products without drug residues, Zheng Silu raised the chicks to 25mur30 days. When the weight of each chicken reached more than 0.35kg, he drove the chickens to the orchard, gradually reduced the amount of mixed feed, stopped using mixed feed after 80 days of age, and fed all raw grains such as corn and rice. Chickens in the orchard mainly feed on weeds, insects, etc., due to large activity, strong muscles, rarely get sick, basically do not use veterinary drugs. After 4 months of stocking, it is sold when it reaches the 1.5-2kg of body weight, which is favored by consumers.
