First, do a good job of cooling work rare birds egg production temperature is 18-26 °C, and the required temperature is relatively constant, it should be done: 1 the best height of the chicken house is 3 meters, in order to facilitate constant temperature, and the establishment of ventilation facilities; 2 Shading plants such as sponges and squashes on the playground; 3 When the temperature is hottest at noon, spraying the water on the roof twice can reduce the temperature by 5 strokes; 4 Cut off the feathers of chicken breasts, legs, and wings to make them dissipate heat faster. This is a measure to ensure high production and stable production. Second, adjust the feed, feed early morning and late summer rare birds in the peak period of egg production, and the weather is hot, protein consumption is great, feed should increase 2% -3% of the protein, in order to ensure its intake should be in the morning and In the evening, the temperature is cool, and when the flock is active, it is guaranteed to drink water and add 2% potassium chloride to drinking water. The effect is excellent. Third, the drug and vitamin C in the summer peak season of egg production, each hen fed a half piece of diethylstilbestrol, the other day, 5-7 times in a row, each egg production can increase 5-10. Vitamin C has the effect of increasing egg production rate, fertilization rate and hatching rate and is involved in the formation of calcium in the eggshell. Therefore, vitamin C should have a content of 0.03% in the feed. But be sure to avoid the use of the following drugs: sulfonamides, chlortetracycline, tetracycline, aminophylline, vaccines, aminoglycosides, male estrogens, etc., because these drugs directly affect the egg production rate and the quality of eggs. Fourth, scientific lighting summer is the peak period of rare birds egg production, is very sensitive to light, must be: 1 light time from the beginning of the egg production gradually increased from 16 hours to 18 hours when the egg production peak; 2 light to regular, cut Can not be used in advance or afterwards, must use the light control instrument; 3 light requirements in the chicken house evenly distributed, 2 meters above the ground level, and to ensure that the light bulb without dust; 4 light at 3 watts / square meter is most effective, can be increased by 12% The egg production rate can also extend the peak time of egg production. Fifth, reduce stress, increase the number of egg-laying boxes The rare birds enter the laying season, especially the high-yielding season in summer, and are extremely sensitive to the sound of the outside world. Walking around, sweeping henhouses, abnormal sounds, etc. can delay or reduce egg production. Therefore, in the peak time of egg production every day 9-14, we must keep the farm quiet, stop all the activities of the chicken house, declined to visit a large number of people, and even the breeders and clothes must be fixed, absolutely prohibited moving, frightened group. The nest box should be placed on a shelf 50 cm away from the ground to ensure that 3 hens are paired. These extremely easily overlooked details have a great impact on egg production. Six, pay attention to a large number of health practices have shown that to high-yield rare birds, they must provide excellent production and reproduction environment, especially the rapid proliferation of bacteria in the summer, you must do a good job chicken house, ensure that the chicken house dry, not wet, no chicken dung, No odor and fresh air can minimize or eliminate the infringement of various pathogenic microorganisms on rare birds during the breeding period and ensure their healthy, strong and productive eggs. This is the world’s most advanced breeding technology, namely, “Biosafety The concept of "eurity" also covers the fundamental methods of farm technical level and bird quality. Seven, pay attention to quality, select a good performance of the population of rare birds, the difference between egg production is very, very few, only dozens of pieces, excellent up to 150-190 pieces, but also in the eggs of the pass rate, fertilization rate, hatching rate, The production performance indicators such as survival rate and raw speed vary greatly. The comprehensive economic benefits of each rare bird can differ by a few times. Therefore, farmers should take the selection of excellent breeding birds as their top priority. When introducing, they must not only look at the genealogy, but also view the management level, professional level, personnel quality, and breeding environment of the breeding birds. Etc., can lead to thoroughbred to ensure high efficiency. Eight, the use of traditional Chinese medicine additives from the Astragalus, Angelica, Atractylodes, wind, Poria, musk, Astragalus, Forsythia, Daqingye, Anemarrhena and other traditional Chinese medicine composition, research and fine feed by 0.5% feed mix. It can not only increase the egg production rate, fertilization rate, hatching rate, and egg quality of rare birds, but also strengthen the growth of rare birds by strengthening the constitution of strong and rare birds, enhancing immunity, and resisting various stress (such as transit, weather mutation, and transportation). The speed and survival rate, the maintenance of meaty game, and the reduction of feeding costs are extremely effective. If you use these measures in a comprehensive manner, you can increase the effectiveness of several times.
