Egg production varies with environment in winter

How can we increase the egg production of native chickens in winter? The environment in which chickens are raised is a big problem.

Diversified feed for native chickens should be corn, sorghum, bran, etc., green feed should be carrots, cabbage, spinach, etc. Chicken laying period also feed some bean cake, corn flour, shell powder, fish bone meal and other protein and mineral feed, and ensure adequate drinking water every day.

Do a good job of disinfection and epidemic prevention, often clean the feces and sundries of chicken pens, regularly replace the bedding in the playground or chicken houses, keep the chicken houses dry and hygienic, usually pay attention to disinfection with Suer solution and mix with Chinese herbal medicine, or drink water with 0.5% potassium permanganate solution.

Add thermal insulation and lighting facilities. Cover the windbreak around the chicken house. Keep the floor clean and spread grass. Paste the doors and windows well. Put down the straw curtain at night to keep warm or ignite the fire to keep the room temperature above 10℃. If the number of chickens raised is small, they can be driven back to the house at night.

Strengthen the management of chicken houses to have a playground outside, chicken houses to set up rest perches, feeding density of 5 per square meter is appropriate. Before putting chickens in the morning, pay attention to adjusting the temperature difference inside and outside the house. You can open the doors and windows of the chicken house first, so that the chickens have a process of adapting to the cold air outside, and then put them on the playground to prevent colds. Usually to feed hanging food, namely feed vegetables, etc., to promote its movement, help digestion, healthy chicken body. Insist on lighting for 13 to 14 hours a day, and turn on electric lighting when natural light is insufficient. In winter, it is advisable to increase the number of feeding times, so as to feed less frequently, 3~5 times a day, so as to ensure that each chicken has sufficient food intake, which is beneficial to its own heat production and weight gain.

The egg laying rate of native chicken was increased by 18% and its disease resistance was enhanced by adding 30~ 40g of 60 ℃ white spirit to each kilogram of feed and mixing well.

Making full use of feed additives Adding 0.05% choline chloride, 0.15% methionine and proper amount of natural yeast to feed can increase laying rate by about 3%.

What do you need to pay attention to when raising chickens in spring?

Spring is coming, all kinds of living things are recovering, so is raising native chickens. All kinds of diseases are also breeding and spreading. So let's take a look together. How should we do well in disease prevention technology and epidemic prevention when raising native chickens in spring?

1, strengthen immunity regular disinfection, early spring breeding greenhouse ventilation is small, water evaporation is reduced, in addition to the hot air in the shed contact with the cold roof and walls will condense into a lot of water droplets, resulting in excessive humidity in the chicken shed, for parasites and bacteria a lot of reproduction conditions. Therefore, we must strengthen the handling, adhere to the cleaning and dryness of the chicken shed, repair the sink in time, do not overfill when adding water, and prohibit splashing water on the ground inside the shed.

2. Strengthen immunity and disinfect regularly. Do a good job of preventing inoculation, preparing for spring, and doing an anthelmintic operation. Immunization should be formulated according to the age group of native chickens, and the program immunization should be implemented. The quality of vaccine should be ensured; Regular disinfection is an important operation that cannot be ignored, usually twice a week. In addition to supplementing antibiotics in the diet, it is also necessary to insist on disinfection of chickens in the greenhouse. Disinfectants with broad spectrum and high efficiency, no toxic and side effects should be selected for disinfection drugs. Attention should be paid to the concentration of drugs. Disinfection should be complete without dead corners. When chickens come on, once a day in the morning and once in the afternoon.

3. Native chickens rely on the feed they eat to obtain heat energy to maintain their body temperature. The lower the external temperature, the more the chicken consumes heat energy to keep warm. According to the determination, the feed consumption of native chickens in early spring is 10% higher than that in other seasons. Therefore, in winter chicken feed must ensure sufficient energy, in addition to ensuring a certain ratio of protein exceptions, should be appropriate to add starch and sugar more high-energy feed, in order to meet the physiological and production needs of chicken.

4. The resistance of native chickens in spring is reduced, so special attention should be paid to epidemic prevention and disease prevention operations, and regular vaccination should be carried out. According to the actual situation, some preventive drugs can also be regularly fed, and the content of vitamins and trace elements in the feed can be appropriately added.

And do less medicine, more disinfection. Many farmers neglect disinfection. In fact, disinfection, especially with chickens, is an effective measure to eliminate pathogenic microorganisms, block transmission routes and protect susceptible chickens from epidemic diseases. Some disinfectants with high efficiency, low toxicity, non-irritation, non-corrosive and relatively cheap prices should be selected. Iodine containing double-chain quaternary ammonium salts should be the first choice. Sodium hypochlorite and compound phenol can be used alternately. When entering chickens and transferring groups, you should drink electrolytic multivitamins. In order to strengthen the immune effect before and after immunization and during immunization, avoid drug interference and stop all drugs except probiotics. At this time, electrolytic multivitamins are used to improve the immunity and resistance of chickens themselves, which can enhance the immune effect.

Dead chickens should be buried or burned. prevent the spread of the disease to healthy chickens.

Pay attention to disinfection and hygiene. First, pay attention to the disinfection and hygiene of the site; second, pay attention to the disinfection and hygiene of breeding tools; third, irrelevant personnel are not allowed to enter and exit the farm at will to prevent the introduction of germs.
