Disinfection of chicken drinking water
1. Bleach: add 610 grams per ton of water, mix well for 30 minutes and then drink.
two。 Antidotal vermicarb: 1Diluted to 5000 ratio, mix well and place for 2 hours to drink.
3. Potassium permanganate: 0.01% concentration with drink, 2-3 times a week, the drug can also be used as a manganese supplement.
4. Paroxysm: 50% of parathion is diluted to chickens with a ratio of 1, 000, 000 to 2000.
5. Peracetic acid: 20% peracetic acid, add 1 ml to every 1000 ml of water, disinfect for 30 minutes and drink.
Points for attention in drinking water disinfection:

Clinical manifestations, prevention and treatment of heat stress in chickens
(1) the tolerance of chickens to heat. Because chickens have physiological characteristics such as high body temperature, exuberant metabolism and no sweat glands, the ability to tolerate high temperature environment is low, so high temperature has become the most harmful stress factor in chicken stressors. According to relevant measurements, the best digestion temperature for laying hens raised in China is 21-24 ℃, the best laying temperature is 15-20 ℃, and the relative humidity is 60% Mel 65%. When the egg production is above 28 ℃, the egg production decreases, and 1 ℃ per liter, the heat dissipation decreases, and the feed intake decreases by 1.6%, and 3% at about 30 ℃.

Effect of airflow on pigs
The motion of air molecules is called air flow, and the air flow that moves horizontally is called wind. The air flow in the atmosphere is caused by the uneven temperature distribution on the earth's surface, and the air molecules flow from the region of low temperature and high pressure to the region of high temperature and low pressure. In weather, the wind speed and direction are often described. The wind speed is the distance of the wind movement per unit time (m); the wind direction is the direction of the wind, expressed in 8 or 16 directions, and the wind direction frequency chart (wind direction rose chart) is drawn according to the probability of the wind appearing in each direction.
