The chicken industry in the United States was surprised to find that some chicken breeders who were not even high-tech have brought a lot of benefits. Here are some of the new ways chickens are widely used in the United States. 1. Lifelong Immunization Method: When the eggs hatch to 18 days, randomly select one point on the eggshell, soften with acetic acid, and inject the vaccine into the embryo. The hatched chicken can be permanently immune. 2. Feeding sugar water: In the 15 hours after the chicken hatches, adding 8% sucrose solution to the drinking water can reduce the death rate by half. 3. Chicks cutting crown method: In the 24 hours after hatching the chick has not opened the elbow, cut off the chicken cockscomb, not only can save feed, but also avoid various adult crown injuries. After the hens start production, the egg production rate can also be increased by 4%. 4. Cut-wing fattening method; select 2-20 days old and robust chicks, stop the wings for two hours before stopping the food, stop water, and tie the chicken wings back and forth to prevent excessive bleeding. Then use a sterilized knife to cut off the wings from the joints, and apply anti-inflammatory powder or mercury in the wound. The chickens were then placed in a low light, warm and quiet place. Two hours later, the chickens could be fed and watered and put into the flock a week later. This wingless chicken consumes less energy, grows faster, and has a fattened pectoral muscle, which greatly increases food value and economic value. 5. Feeding Methionine: The addition of methionine to the feed will allow the broiler to grow rapidly and the feed will be reduced by half. 6. The method of feeding choline: 0.05% choline was added to the feed, the egg production rate increased by 3%, and the average egg weight increased by 2.8 g. 7. Feed Manganese Method: Adding 20 to 25 ppm of manganese to the chicken feed can make the hen produce hard shell eggs, but the egg shell thickness does not increase. The broken rate of this egg is greatly reduced for storage and transportation. 8. Feeding sunflower seeds: Incorporation of 8% sunflower seeds or 10% wood shavings in the feed of laying hens can reduce the cholesterol in the egg yolk by 13%. 9. Change lighting method: In the first month of hen laying, change the daily period to 28 hours, and change the light according to 12 hours of light and 16 hours of dark interval, the average egg production will increase by 10%, and the eggshell Strong, little egg production. 10. Music chicken-raising method: When chicks hatch, the sound of roaring sounds when young chicks are hatched can make chicks hatch neatly and improve hatching rate. A serene serenade of 12 hours of regular chicken play is played on a regular basis for one night. It is suspended for one hour for every one hour of continuous broadcasting; it lasts for 7-8 weeks. This method can increase the daily gain of broilers by 3%, and the egg production rate of laying hens increases by 10%. In addition, the chicken is quiet when enjoying music, and it also saves on feed. China Agricultural Network Editor
