[Additional insulation and lighting facilities] The house is covered with windbreaks. The floor is kept clean and covered with grass. At the same time, the doors and windows are well-kept. In the evening, the straw curtain is kept warm or heated to keep the room temperature at 10°C. the above. If the number of chickens raised is small, they can be returned to the house at night. ã€Strengthen management】 There must be a playground outside the henhouse, and a rest rack should be set in the henhouse. The breeding density should be 5 per square meter. Before placing the chicken in the morning, pay attention to adjusting the temperature difference inside and outside the house to prevent the chicken from catching cold. Normally, feeding a confinement diet is necessary to increase feed intake to promote its movement, help digestion, and build a healthy chicken body. The lighting is maintained for 13 to 14 hours a day, and lighting is turned on when there is insufficient natural light. The number of feedings should be increased in the winter so as to reduce the amount of feeding. Feed 3 to 5 times a day to ensure that each chicken eats adequately, which is beneficial to its own heat production, but also conducive to weight gain. ã€White Liquor Mix】 Feeding 30 to 40 grams of white wine of about 60 degrees per kilogram of feed and feeding it after mixing will increase the egg production rate of the native chicken by about 18%, and at the same time, it will increase its resistance to diseases. ability. [Diversification of Feed] The concentrated feed of chickens should be based on corn, sorghum, bran, etc. Green feed should be dominated by carrots, cabbage, and spinach.

[Making full use of feed additives] Adding 0.05% of choline chloride, 0.15% of methionine, and an appropriate amount of natural yeast to the feed can increase the egg production rate of the native chicken by 3%. [Do a good job of disinfection and epidemic prevention] Frequently clean the excrement and debris of the chicken house, change the litter regularly, and always pay attention to Suer water disinfection and mix with Chinese herbal medicine, or drink with 0.5% potassium permanganate solution.
The chair side CAD / CAM repair system has obvious advantages in aesthetic effect, operation time, patient participation and operation convenience. Discussion: traditional repair method: after the model is transferred, it will be sent to the technician's room for processing and making the final prosthesis. About one week, the final prosthesis will be tried on, grinded and bonded. The prosthesis was made in the technician's room. The patients need to accept the aesthetic effect of the prosthesis passively without any sense of participation. The implant repair method of chair side CAD / CAM system: obtain computer three-dimensional model by blue light scanning method, design and make personalized abutment and all ceramic restoration on computer, dye, glaze and bond after trial wearing, the whole restoration is made by chair side, patients can directly participate in the restoration design, and feel more involved. Conclusion: in the implant area of the anterior teeth, compared with the traditional implant repair method, the chair side repair system can get more satisfactory results, which is worthy of clinical application and promotion.
