Management points for raising chickens in summer

Strengthen feeding management and strict sanitation and disinfection measures

1. Provide adequate drinking water in a timely manner. The water content of eggs is about .73%, and the daily water consumption of chickens is 90-325 ml. The higher the egg production rate, the greater the water requirement. For every 10% increase in egg production rate, the daily drinking water per bird increases by 12 ml. The amount of water in summer is doubled in winter, about 2-3 times the amount of feed intake. Therefore, to ensure that the chicken drink clean cold water in a timely manner, the water temperature is about 10 degrees, it is advisable to enter the water pipe of the chicken house to be buried in the ground 90 cm. The best time to drink water should be selected at 6-10 in the morning, and the chickens have the most appetite. When the temperature exceeds 30 degrees, add the right amount of vitamin C per kilogram of drinking water plus 200 mg or 0.1% of baking soda. This will improve the cardiovascular metabolism of the chicken and enhance the body's ability to adapt to high temperatures.

2. Clear chicken manure in time and disinfect regularly. For disinfection of the chicken battery cages, ground, walls, sinks, troughs, etc. of the house, choose a disinfectant that is less corrosive and has a strong killing power against the pathogen. Keep the air fresh and reduce the content of harmful gases such as hydrogen sulfide and ammonia in the house.

3. Reduce various stress factors. Human factors such as transfer, transportation, and vaccination should be avoided as much as possible. When it is necessary, it should be chosen at night or in a cool time. In addition, laying hens must have a dark rest time of more than - hours, otherwise the breakage rate of the eggshell will increase. At the same time, add vitamin 1 in drinking water! The same amount as the previous 0.63% ammonium chloride can also alleviate the stress of the flock.

Change the feeding method and adjust the diet formula

1. Adopt two feeding methods. In the morning, it should be fed early, and the feeding time should be extended at night. When it is hot in the afternoon, it can be fed or green-green feed, such as chopped watermelon rind.

2. Appropriately improve the nutritional level of feed. For laying hens, the energy level of the diet can be reduced by about 10%, and the protein level is increased by 1% to 2%. 3% of bean cake or 2% of fishmeal can be added to the diet during specific operations. For broilers, the feed energy can be reduced by 10-15%, and the crude protein is increased by 1%-1.5%. In the specific operation, the cod liver oil can be sprinkled in the feed by 0.3-1 ml per chicken. Note that the summer feed is mildewed and should be ready for feeding. The 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. The general addition amount is about 2 times normal. In particular, pay attention to increase the content of vitamin 1, vitamin 2, vitamin 3 and vitamin e to promote the absorption of calcium and phosphorus in chickens.

4. Timely calcium supplementation. Most of the calcium absorbed in the morning is stored in the bones. The calcium absorbed in the afternoon or evening can be used for the formation of the eggshell at night. Therefore, the laying hen should be properly replenished at dusk, and the amount should be 2.3% of the diet.
