Egg laying chicken summer management points
High-temperature season is a threat to chicken production. Hot summer rain, high humidity, insects, combined with high temperatures, low wind, low pressure, resulting in reduced appetite and decreased egg production. In the summer, the management of hens is mainly focused on preventing heatstroke, reducing appetite, preventing appetite, and preventing heatstroke in chickens. The following factors should be taken into account during production: 1. The temperature and humidity of the broiler house are the necessary indicators to promote egg production. The humidity reaches about 55% and the temperature reaches about 25°C, which is the best environment for laying eggs. When the temperature reaches above 28°C, we must pay attention to the response of the flock. Especially at noon sun, the temperature of the house often reaches about 32°C. As the heat increases and the water evaporates, the humidity will constantly decrease, and it will easily occur. Rapid dry heat. In addition to properly opening the windows, the ventilation should be increased. In addition, the curtains can be hung with water to reduce the temperature, the tap water can be circulated and cooled, and the shaded nets on the windows can be cooled, or the fans can be installed at the same time. 2. Adjust feed nutrient levels During the high temperature season, feed intake decreased, and insufficient protein intake directly affected egg production. Experiments have shown that methionine and lysine balanced low-protein diets are more valuable than diets with higher total protein levels. They can adopt protein-enhanced methods, adjust formulas, increase the use of lysine, lysine 0.1%, or increase. 2-3% of the bean cake, or an increase of 2-4% of the fishmeal, achieves a good but low quality target. According to the reduction of feed intake of chickens, the proportion of calcium and phosphorus in feed should be properly adjusted, generally increasing 5-10%; adding 1-3% of vegetable oil at the same time to increase energy level; dietary vitamin E, vitamin C, vitamin K The content of biotin and riboflavin should also be increased accordingly. It is advisable to regularly measure the feed intake of chickens and adjust the dietary nutrient levels according to the actual feed intake to meet the needs of laying hens. 3. Strengthen feeding and management to reduce the density. 4 white cage chickens per cage, 3 brown cage chickens per cage; sufficient water, the growth of chickens can not be separated from the water, every 60 eggs produced by laying hens need water 42 -45 grams, 2-3 grams of water is needed for each gram of feed. Therefore, laying hens need to feed 2-3 times of water for the environment, and 3-5 times of water for the hot summer season. It is clean and cool water; choose cool morning and night feeding; strengthen ventilation and ventilation, high temperature in summer, rapid microbial growth, rapid evaporation of water, rapid metabolism of chicken body, ammonia and CO2 in feces is also fast, so we should pay attention to the air Oxygen supply and circulation, laying eggs long-term lack of oxygen or fresh air will affect the production of eggs; frequently remove chicken manure, summer layer chickens are relatively dilute, high humidity, chicken manure easily fermented to produce ammonia, hydrogen sulfide and other harmful Gas or other odor, easy to induce respiratory diseases. Therefore, the manure and litter should be cleared in time (at least once every other day) to prevent pollution and keep the house clean, dry and sanitary. 4, do a good job of chicken disease prevention due to many factors in the summer heat, chickens are susceptible to disease, so we must do routine immunization work to prevent the occurrence of the disease. To prevent the occurrence of digestive tract disease in chickens, a common and simple method is to mash up the garlic, mix it in the feed at a rate of 0.5%, feed it 1-2 times a week, and also give the chicken a high dose of 1 ounce. Potassium manganate water can achieve ideal results 1-2 times a week.
