Management of laying hens in the summer should pay attention to the following points.
1. Strengthen the prevention of disease control
In the summer, breeding of mosquitoes and flies, rapid bacterial growth, and easy-to-sick chickens, it is necessary to strengthen the disinfection of poultry houses to prevent the occurrence of diseases. The floor is cleaned and dug sand and soil. The addition of fly maggot to the feed for 4 weeks can effectively reduce the breeding of mosquitoes and flies, and significantly reduce the incidence of diseases transmitted by mosquitoes and flies. Regularly adding astragalus polysaccharide, phytohemagglutinin, hypericin or ciprofloxacin lactate, lysozyme to the feed can prevent the occurrence of bacterial diseases and viral diseases. In addition, doing a good job of vaccination is also the key to preventing the occurrence of infectious diseases.
2, adjust the diet nutrition
During the hot season, the chicken intake is relatively reduced. At this time, the ingredients of the diet can be properly adjusted to ensure that the chicken has sufficient nutrition.
Adding 1% to 3% fat to the feed can not only increase the energy level of the feed, but also increase the feed palatability and increase the feed intake of the chicken.
Decrease the eggs properly to reduce the crude protein content in the feed and maintain the content of essential amino acids. Add 0.1% to 1.5% methionine and 0.65% lysine.
3, control the environment temperature of the house
Reducing heat radiation and heat of reflection in the chicken house Before or after planting a awning in a chicken house, planting grass around the house, white roofing or roofing inside the house, etc., it can effectively reduce radiant heat and reflected heat and achieve cooling. purpose.
Ventilation and cooling The chicken house door is equipped with water curtains. The house is equipped with electric fans. The house is sprayed with water from the top of the house and from time to time to enhance ventilation, which can effectively reduce the temperature inside the house.
Reduce the rearing density, appropriately reduce the rearing density, and reduce the chicken's own heat production, so as to reduce the temperature and reduce the stress.
4. Application of anti-stress drugs and additives
Adding enough vitamins in vitamin feeds, especially vitamin C and vitamin E, not only prevents vitamin deficiency caused by high-temperature vitamins in the feed, but also increases the anti-stress ability of chickens. Vitamin E helps the chicken to achieve the best immune function and enhance the resistance of the chicken body.
Add particulate calcium and electrolytes Add appropriate amounts of particulate calcium and electrolytes. The addition of electrolytes can not only compensate for the lack of minerals, maintain the acid-base balance, but also improve the performance of chickens during heat stress. Adding the appropriate amount of granular calcium in the diet can supplement the low blood calcium in the blood on the one hand, and can also increase the egg production rate and improve the egg shell quality on the other hand.
5, strengthen feeding management
The temperature is high before and after noon during the hot season, and the chickens eat less or even refuse to eat. Special feeding methods can be adopted and the feeding time can be changed, that is, feeding or not feeding from 8am to 6pm in the morning, but sufficient drinking water (better well water) should be given. Feeding should be done before 8am and After 6 pm, it will be supplemented again at night. Where conditions permit, the powdered material can be changed to pellets, and the feed can be slightly wetted, increasing the feed intake of the chicken and reducing the effects of heat stress.
