In summer, high temperatures, high humidity and heavy rain are frequent occurrence seasons of the farmer's disease. In order to keep the ecological stocking chickens productive during the summer, there is no “resting†in the fight. Farmers must conduct scientific stocking in order to obtain good economic benefits.
First, do a good job summer cooling temperature and egg production has a direct relationship between the egg production, the most ideal egg production temperature is 15 °C ~ 24 °C, 25 °C above the egg production rate gradually decreased, 30 °C above the chicken will appear mouth breathing, two When the wings are open, the egg production rate is significantly reduced or even stopped. It is probable that a large number of deaths will occur at ambient temperatures above 35°C for a long time. Therefore, in order to keep the chickens producing more eggs in summer, it is necessary to take a awning in the stocking area, and the ventilation and water wall of the house should be used to cool and prevent heat. The environment of the house and chicken farms should be kept below 28°C.
Second, the supply of adequate drinking water The amount of drinking water with the changes in the ambient temperature and a substantial change in the summer drinking water is about four times the winter, about 3.5 times the intake, the chicken does not like to drink high temperature water, so the summer Care should be taken to make the chickens clean drinking water, preferably spring water. Because the increase in water temperature requires a lot of heat, even if the ambient temperature rises, the body temperature rises very slowly. At the same time, the excretion of water along with excreta increases, taking away a lot of body heat. When the outside temperature is 32°C, a chicken can drink 300 ml for one day, which can take away 4,500 calories. The effect of cooling and preventing heatstroke is very obvious, and the chicken production rate increases.
Third, adjust the nutrient summer high temperature, to maintain the heat needed to reduce the need for firewood, while the protein needs to be relatively improved, the effective method to maintain the production of eggs in summer is to use animal and vegetable fats instead of carbohydrates, can increase in the feed 3% beancake , 2% fishmeal, which will change the ratio of energy and protein, while also paying attention to maintaining the balance of amino acids.
Fourth, add anti-heat stress additives hot summer season, add appropriate amount of anti-heat stress additives in the chicken feed supplement to help increase egg production, add vitamin C in feed, electrolytic multidimensional, and add zinc chloride in drinking water, Ammonium chloride, sodium bicarbonate, aspirin, etc., and appropriately reduce the salt content, can effectively reduce the heat stress hazard, and increase the egg production and quality of the chicken.
Can also be fed with Chinese herbal medicine additives, it can not only prevent certain diseases, but also resistance to heat stress, have a significant effect on improving chicken production performance. Such as heat-fighting and fire-fighting type: plaster, scorpion, etc., can help the body heat dissipation; Shu summer class: musk, wormwood, heat to prevent heat stroke; tranquilizers shock class: Polygalaceae, Bo Ziren, Suanzaoren, can tranquilize God It is shocking and has anti-heat stress effect.
Fifth, to strengthen the stocking management for fresh, clean cold water throughout the day; to minimize the breeding density can effectively reduce the ambient temperature; pay attention to early release chickens, late-catch chickens, as far as possible to avoid the hot time to allow the farmer to feed in the wild.
Sixth, to prevent and cure epidemic diseases in summer is a period of weak chickens, and we must do a good job in prevention and control of epidemics. Adhere to 2 to 3 times a week to sterilize chickens to keep the house clean. Strict implementation of immunization procedures, regular surveillance of Newcastle disease antibodies, abnormalities, and timely response. Regular spraying of insecticides, such as pyrethrum, which is harmless to humans and animals, is performed in the chicken house and in the stocking place to completely eliminate insects such as mosquitoes, flies and cockroaches. In the supplemental feeds, drugs such as chlorfenadine and globulin powder are regularly administered to prevent chicken diseases.
