During the hot summer season, the weather often causeschickenDecreased feed intake, slow growth, reduced egg production, and even death of chickens. Based on years of work experience, during the summerRaising chickensKey management points, let me share some insights.
1、 Improve the chicken coop environment and create a microclimate
1、 Change the ambient temperature.layerThe suitable temperature for laying eggs is 13-25 degrees Celsius, and summer temperatures generally exceed 25 degrees Celsius. Therefore, changing the environmental temperature and creating a good microclimate for the egg laying chicken flock is the top priority for chicken farmers in summer. The specific method is to do a good job of greening in spring, planting trees and vines around the chicken coop, and removing weeds around the coop; Build a shade shed on the sunny side of the chicken coop before the arrival of summer; Paint the roof and exterior walls of the chicken coop white! Brush it white "to reduce heat absorption. The method is to dissolve 0.50 kilograms of salt in 46 kilograms of water, then add 40 kilograms of lime, 4.2 kilograms of white cement, and 68 kilograms of water, stir evenly, and paint or spray the roof and exterior walls. This method can reduce the temperature inside the chicken coop by 1.5-2 degrees. In addition, it is important to strengthen ventilation and convective heat dissipation in the chicken coop. If conditions permit, wet curtains can be installed and longitudinal ventilation can be used to cool down.
2、 Disinfect chicken with spray.
Encountering sustained high temperatures, especially in farms with a high concentration of chicken farming! Household "install spray equipment in the chicken house. Generally, two water pipes are 6 meters away from each other, and a nozzle is installed every 3 meters on the water pipe. spray several times at noon when the weather is hot, which can reduce the house temperature by 3-5 degrees" (Note: choose a disinfectant with no irritation and small smell to avoid inducing respiratory diseases in chickens ".
Reduce the feeding density. Increase the number of water dispensers and feeding area. In summer, it is necessary to clean up the chicken flock in a timely manner, eliminate sick, disabled, weak chickens, and fake hens to reduce feeding density and costs.
Four "shearing to cool down. Chickens do not have sweat glands, and their way of lowering body temperature is by accelerating breathing, opening their mouths wide, and spreading their wings to dissipate heat. Therefore, at night, some feathers that affect heat dissipation can be cut off from the neck, back, wings, chest, abdomen, inner thighs, etc. The principle of shearing is: the depth of shearing should not damage the skin and the large hair ducts should not flow after shearing. Long feathers on chicken tails and wings should not be cut, and should be cut less in early summer and more in summer.
3、 Strengthen feeding management and strictly implement hygiene and disinfection measures
1. Timely supply of sufficient drinking water. The moisture content of eggs is around 73%, and the daily water intake of chickens is 90-325 milliliters. The higher the egg laying rate, the greater the water requirement. For every 10% increase in egg production rate, the daily water intake of each chicken increases by 12 milliliters. The amount of water consumed in summer is twice that of winter, approximately 2-3 times the amount of food intake. Therefore, it is necessary to ensure that the chickens drink clean cold water in a timely manner, with a water temperature of around 10 degrees Celsius. The tap water pipe entering the chicken coop should be buried 90 centimeters underground. The time for drinking water should be between 6-10 am in the morning, when chickens have a strong desire to drink. When the temperature exceeds 30 degrees, in drinking water
Adding an appropriate amount of vitamin C and 200 milligrams per kilogram of drinking water or 0.1% baking soda can improve the cardiovascular metabolism of chickens and enhance their adaptability to high temperatures.
2. Timely remove chicken manure and disinfect regularly. Disinfectants with low corrosiveness and strong pathogen killing ability should be selected for disinfection of the floor, walls, sinks, feeding troughs, and other areas of the chicken coop. Ensure fresh air and reduce the content of harmful gases such as hydrogen sulfide and ammonia in the chicken coop.
3. Reduce various stress factors. Efforts should be made to avoid human factors such as group switching, transportation, and vaccination. When it is necessary to implement, it should be done at night or during cool weather as much as possible. In addition, laying hens must have at least - hours of dark rest time, otherwise the rate of eggshell damage will increase. At the same time, add vitamin 1 to drinking water! The same dosage of 0.63% ammonium chloride can also alleviate stress in chicken flocks.
3、 Change the feeding method and adjust the dietary formula
1. Adopting the two end feeding method. Feeding should be done early in the morning, and the feeding time should be extended at night. During hot midday, feeding can be done without feeding or only with green feed, such as feeding chopped watermelon peels.
2. Properly increase the nutritional level of feed. For laying hens, the energy level of the diet can be reduced by about 10%, and the corresponding protein level can be increased by 1% -2%. Specific operations can include adding 3% soybean cake or 2% fish meal to the diet. For broiler chickens, the feed energy can be reduced by 10-15%, and the crude protein can be increased by 1-1.5%. Specifically, 0.3-1 milliliters of cod liver oil can be sprinkled in the feed for each chicken. Attention, feed is prone to mold growth in summer and should be fed and prepared on site. Storage time should not be too long.
3. Increase the content of various vitamins. When the weather is hot, the vitamin content should be increased, usually by about twice the normal amount. Special attention should be paid to increasing the content of vitamin 1, vitamin 2, vitamin 3, and vitamin E to promote the absorption of calcium and phosphorus by chickens.
4. Timely calcium supplementation. Most of the calcium absorbed by chickens in the morning is stored in their bones, and only the calcium absorbed in the afternoon or evening can be used for the formation of eggshells at night. Therefore, laying hens should supplement appropriately at dusk, with an amount of 2.3% of their diet.
4、 Preventing and treating common summer diseases
In addition to normal vaccination, emphasis should be placed on preventing enteritis, typhoid fever, etc. If intestinal diseases are found, antibiotics such as norfloxacin and methicillin should be administered in a timely manner.
In addition. Attention should also be paid to eliminating mosquitoes, flies, mice, etc.
