How to Improve Hen Egg Production Rate in Winter and Spring
2024-11-09 06:59:57
In the early spring of winter, the egg production rate will drop significantly due to the low temperature. In order to stabilize and increase the egg production rate of chickens, the following technologies and measures must be taken:
First, cold and warm. It is best to use closed or buckled plastic greenhouses. The roof of the enclosed house and the north wall of the house should be provided with an insulation and cold-proof layer to keep the temperature of the house above 10°C; if the plastic greenhouse is to be buckled, the insulation layer should be added to the north wall and a double plastic film should be used. Doors and windows at night should be covered with straw curtain insulation to prevent thieves from invading. The chicken stadium should also be covered with plastic film. The suitable egg production temperature for chickens is 17 to 21°C. If the chicken house does not reach this temperature, other heating measures should be taken in time.
Second, ensure nutritional needs. In the winter and spring seasons, the laying hens should be fed full price diets. Reference feed formula: 62% corn, 12.1% soybean cake, 13% wheat bran, 4% fish meal, 1% bone meal, 7% shell powder, 0.3% food bowl, 0.5% auxin, 0.1% methionine. In addition, add 10 grams of multivitamin per 100 kg of feed. Feed 4 to 5 times a day, feed dry powder during the day, and feed pellets at night. At the same time, some irritating substances should also be added to the feed to reduce feed consumption and increase egg production. Such as adding 10% to 20% carrots in the diet, can increase egg production rate by 11%, and can extend the egg production period, improve the disease resistance of chickens; add 3% to 5% feather meal, the egg production rate can be increased by 20 %, and can prevent the occurrence of plume, anal and other snoring; add 0.1% to 0.2% of chili powder, can improve chicken intake and cold capacity; add 3% zeolite powder, can increase egg production rate of 12%, reduce feed consumption About 40%.
Third, increase the light. Artificial light can be added daily for 13 to 16 hours, with 3 to 5 lights per square meter, 2 meters from the ground, and a distance of 3 meters between the light and the light. Turn on the lights twice a day, for the first time from 5am to dawn and the second from dusk to 8pm. The lighting program should not be changed easily. Wipe the lamp once a week to increase the brightness. Be careful not to use fluorescent lighting.
Fourth, strengthen sports. The production of laying hens should be maintained for a certain period of time each day. Sand pits should be set up on the sports ground to facilitate sand bathing and supplementation of sand grains in the stomach. Before opening a chicken, open some windows in the house to gradually reduce the temperature, and then put chickens out. Keep the chicken early to return home early and watch the temperature change to prevent the chicken from catching a cold.
Fifth, ventilation and moisture. When the air in the house is found to be dirty, the ventilation should be opened even if the temperature is low. When the house temperature is higher, the ventilation rate can be appropriately increased. In general, the airflow rate in the house should be kept between 0.1 and 0.2/sec. To control the density of chickens in the house, generally no more than 6 breeding animals per square meter. Scatter 350 grams of superphosphate per square meter of ground to eliminate ammonia in the house and reduce chicken respiratory disease.
Six, prevent cold stress. When the chicken house temperature is low, the proportion of energy feed should be appropriately increased to reduce the protein content. Generally, 1 to 2 days before the onset of the cold wave, each chicken will increase its feed by 10 to 20 grams per day. If the temperature drops by 3°C, the chicken should be fed 5 grams of feed for 3 to 5 days. When the temperature rises to normal, Restore the original amount. In addition, the chicken can be given oral rehydration basin (ORS) on the day before the sudden drop of temperature. The formula and drinking method: 3.5 grams of sodium chloride, 1.5 grams of potassium chloride, 2.5 grams of sodium bicarbonate, 20 grams of glucose, and 1000 milliliters of water About, even drink 3 to 4 days.
Seven, with chicken disinfection. That is, a chicken house is sprayed with a certain concentration and dose of disinfectant to prevent chicken disease. Disinfectants should use broad-spectrum, high-efficiency, non-toxic, no side effects, and high adhesion drugs. Usage: 100-200 grams per square meter in winter; 150-250 grams per square meter in spring. At high temperatures at noon and in the afternoon. Using an aerosol generator with a nozzle diameter of 80 to 120 microns, a spray of 60 to 80 cm from the bird body. Under normal circumstances once a week; such as chicken infectious diseases, low humidity, dust more, can be increased appropriately (2 to 3 times a week), the drug concentration should also be reduced by 30% to 50%.
Eight, epidemic prevention. Do a good job of daily cleaning and disinfection, and take preventive drugs. One terramycin should be fed to each chicken. After feeding for 5 days, it should be repeated every 7 days; or every week, each chicken should be given 1 tablet of long-acting sulfonamide. , can enhance the chicken body resistance to disease.
