First, improve the feeding environment
1. Inspection and maintenance of chicken houses and equipment Before the summer season (in mid-May in northern China), conduct a comprehensive inspection of the house. (1) Check whether the ventilation equipment is complete and effective, ie: Inspection of vertically ventilated houses. Whether the fan motor operation is normal (to meet the requirements of the fan to meet the maximum wind speed in the house is 3m/s), check whether the belt is aged and loose; timely maintenance, cleaning and lubrication of the shutter, ensure the normal opening and closing, check whether the tightness of the house is Good, accurate calculation of the area of ​​the air inlet, scientific setting and adjustment of the location of the air inlet; the natural ventilation of the chicken house roof must be equipped with skylights, north and south sides of the bottom of the wall to provide ventilation, to ensure the smooth flow of air within the house, and the other to install ceiling fan. (2) Check if the water pump, filter paper, and fan are working properly. (3) Check whether the function of the drinking water system is perfect, whether there is leakage and jamming (check the drinker's nipple and filter one by one). According to the chicken's habit of throwing water down, the conditional chicken farm may be provided with a sink. Double drinking water system can not only satisfy the chicken's habits, but also can meet the chicken's drinking water requirements.
2. Do a good job in greening to improve the hen house The micro-climate house is surrounded by trees and grass. It is best to plant tall trees so that it does not affect the ventilation and can play a role in shading, avoid direct sunlight on chickens, planting lawns can absorb large amounts of heat, To prevent sunlight from reflecting into the house, it has been proved that reasonable greening can effectively reduce the Sherwin's temperature by 3-5°C.
3. Supply chickens with sufficient clean drinking water The water temperature should be as low as possible. Conditional chicken farms can use the water at the end of the water line to recycle water after treatment to reduce the water temperature.
4. Spray water to reduce temperature Every day from 11:00 am to 16:00 pm in the hottest period, that is, the house temperature exceeds 33°C. Use a sprayer or sprayer to spray the water on the top of the house and the chicken body. When the body spray cools, 30-40 cm above the head of the chicken spray cold water best, and the smaller the better the fog, while spraying the water to ensure the air flow in the house, it is best to take vertical ventilation. Note: In the case of high temperature and high humidity (stifling heat) outside the house, the effect of spray water cooling is poor. At this time, we must strictly control the amount of water spray.
5. The roof is cooled. When building a chicken house, the roof insulation performance should be reliable. In summer hot weather, the roof should be painted white. It can reflect the sun's heat radiation to reduce the temperature. The breeder farm can use the roof water spray. The method can reduce the chicken house temperature by 2-3°C.
6. Adjust the flock density Before the summer season, adjust the cage chickens in time, that is, place as few chickens as possible in each cage so that the chickens in the house can be distributed evenly, reducing the artificial density caused by excessively large chickens. The heat stress phenomenon is particularly important in the case of chicken house dissatisfaction.
7. Do a good job of sanitation in a timely manner to remove feces and control the breeding of mosquitoes and flies. In summer, when the temperature is high, the chicken's breathing speeds up and the water evaporates. If the chicken has a large amount of water, the chicken's water metabolism will be large, which will inevitably cause an increase in humidity. Therefore, it must be ventilated in time to keep the air fresh. It is advisable that people do not feel dazzling, weeping, no sniffing, or excessive ammonia smell in the chicken house. Add avermectin 10 mg/kg body weight to the feed. Dispose of the medicine once. Once every 20 days, it can effectively control the fly.蛆 å³ å³ ç¹ ç¹ ç¹ ç¹ ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; 食 食 食 食 食 食 食 食 食 食 食 食 食 食 食 食 食Once a day, and more than two disinfectants should be used interchangeably.
8. Strengthen epidemic prevention work in the summer Focus on the prevention of conditions such as E. coli disease and mycoplasma diseases, timely monitoring of antibody levels of Newcastle disease, bird flu, transmission and other viral diseases, timely vaccination according to monitoring results, and keep chickens The group's good health level enhances its resistance and reduces the effects of heat stress and disease on chickens.
Second, adjust feed nutrition
1. Increase dietary crude protein and amino acid additions Due to high summer temperatures, the feed intake of chickens is reduced, so the protein content in the diets of laying hens should be appropriately increased, generally increasing to 18%. If the egg production rate is above 88%, The protein level can be increased to 18.5%, and the amino acid content should also be increased appropriately (especially the content of methionine and lysine must be increased).
2. Increase vitamin and mineral levels According to the characteristics of high-temperature weather, the chicken feed intake is reduced, intestinal absorption is poor, and vitamins are easily lost. At least the level of multivitamins in the diet is increased by 15% to 30%; The content of minerals, calcium absorption in summer high-temperature layers is inhibited, eggshell thinning. Therefore, it is necessary to add calcium in time. Generally, high-quality shell powder can be used for feeding at dusk, and the dosage is 1% to 1.5% of the diet. Studies have shown that only calcium absorbed by laying hens in the afternoon and evening can be directly used for the formation of egg shells, and calcium absorbed in the morning is mostly stored in bones.
3. Add fats and fats to the feed When the laying hens are put into production, energy determines the rate of egg production. Feed intake decreased at high temperatures and insufficient energy intake directly affected the egg production rate. Addition of oils and fats can not only increase feed energy, improve feed palatability, increase feed intake, but also reduce metabolic heat production. Tests have shown that adding 1% to 2% soybean phospholipids in feed can significantly increase chicken egg production.
4. Adding electrolytes and heat-stress-resistant drugs Adding Vc200mg per kilogram of feed at high temperatures can increase the egg production rate by 9.2%. It can also increase the chicken's resistance and immunity, and reduce the egg-breaking rate and material-to-egg ratio. Zinc Bacitracin is currently a good heat stress reliever. Zinc Bacitracin 10 mg per kilogram of feed can significantly increase feed intake and reduce metabolic heat production. The addition of 0.2% to 0.5% NaHCO3 in laying hens' diets can significantly increase the egg production rate under heat stress conditions, regulate blood acid-base balance, and also increase eggshell thickness and reduce egg breakage. In addition, VE, sodium citrate, fumarate, etc. also have a role in reducing heat stress.
Third, strengthen feeding management
1. Try to avoid turning groups, cutting off bugs, and immunization during hot weather. The artificial insemination time for breeding chickens must be adjusted to after 16:00 in order to reduce unnecessary losses caused by external disturbances and stress.
2.According to the relatively cool nature of the nighttime in summer, the light-filling time will be adjusted. Generally, the lights will be turned on at about 3:00 in the morning and turned off at about 8:00 in the evening. The feeding time will be adjusted accordingly to the cool time period to promote chickens. Eat more food. In short, comprehensive measures such as improving the feeding environment, scientifically and rationally adjusting the formula of diets, and adding heat-stress resistant drugs can ensure that laying hens survive safely in summer.
