Summer temperatures are high, the sun’s rays are good, and many bacterial viruses can be directly inactivated by ultraviolet light, thus reducing the incidence of disease. Due to the high temperature and convenient ventilation, the air in the Hongshe is good, so the natural incidence of respiratory diseases is reduced. However, due to the hot weather, the temperature often exceeds 30 °C, which may cause heat stress in the laying hens, and the Central Department. In addition, there are many rains in summer, the humidity is high, and the number of mosquitoes increases. Therefore, the incidence of coccidiosis, bacterial diseases, mold pain, and chicken pox increases.
How to grasp the characteristics of summer climate and manage the laying of laying hens has become the top priority of farmers management. To this end, the author based on the experience of poultry farming equipment suppliers for many years, the four-point work that the laying hens must do in the summer is introduced as follows, hoping to provide reference and help for everyone:
1. Heatstroke prevention and cooling
The optimum ambient temperature for laying hens is 15 to 25 ° C, and the production performance is best in this temperature range. In summer, the temperature often exceeds 30 °C, and chickens are prone to heat stress and the Department of Health. Therefore, the primary problem in summer feeding management is the cooling of the Department of Defense. Commonly used methods include enhanced ventilation, use of wet curtains, sprays, etc. to cool down; you can also build a sunscreen net outside the chicken house, conditional can also increase the greening around the chicken house, whitewash the chicken house, etc., take a variety of measures, The laying hens can be kept in a relatively suitable temperature environment to maintain the performance of the laying hens.
2. Increase nutrition
In summer, due to the heat, the feed intake of chickens will be significantly reduced. If the diet does not increase nutrients, it will not be able to meet the requirements of body growth and egg production, thus reducing the overall performance of the birds.
The level of their diet should be adjusted to “three increase and one decrease”, namely: appropriate increase of protein feed, appropriate increase of green and succulent feed, appropriate increase of mineral feed and appropriate reduction of energy feed. Thereby meeting the needs of chicken growth and laying eggs.
3. Anti-heat stress
Commonly used anti-heat stress drugs are vitamin C, electrolytes such as potassium chloride, ammonium chloride, sodium bicarbonate, etc., as well as some traditional Chinese medicine additives (such as heat and fire-reducing: plaster, medlar, etc., can help the body Heat dissipation; Department of the Department: Musk, Artemisia, can dissipate heat to prevent the Central Department; Anshen Town shocked: Yuanzhi, Baiziren, Suanzaoren, etc.), can calm the nerves, have anti-heat stress.
