Post-flood animal husbandry precautions

Floods have brought great difficulties to the production and management of the livestock breeding industry. After livestock and poultry pens have been immersed in flood waters, the number of pathogenic bacteria in the breeding environment will increase accordingly, and the chances of livestock and poultry becoming infected will increase accordingly. As a result, the feed is susceptible to mildew under conditions of high humidity and high temperatures. In order to restore production and reduce losses as soon as possible, in addition to the normal management of livestock and poultry, the following points should also be noted:

Thoroughly clean up the house and do a good job of disinfection. Thoroughly sterilize the house. The general procedure is to first perform mechanical flushing, paint the walls, enhance ventilation, and then use 2% hot caustic soda solution or 8% to 10% lime and 1% caustic water to spray walls, floors, and interior spaces. Cage and other utensils are sprayed with 3% of sux children or 0.2% to 0.3% of peracetic acid. After disinfection, the pens should be sealed for a period of time to ensure the disinfection effect.

Disinfect the surrounding environment. The floor and the exterior wall of the house within 5 meters around the house can be sprayed with 2% to 3% caustic soda solution, and can also be sprayed with 30 to 50 mg sodium hypochlorite per liter. The roads and manure heaps that transport livestock and poultry excrement can be sprayed with peracetic acid or caustic soda solution, and can also be flame-sterilized and disinfected. The cleaned feces, dirt, and sundries can be fermented, stacked, sealed, and sterilized using biological heat to achieve the purpose of killing non-Bacillus and parasite eggs. The commonly used environmental disinfectant drugs include iodine-binding drugs (edivol, sulfofoline), compound phenols (bactericidal adversaries, farm music), sodium dichloroisocyanurate, and double-stranded quaternary ammonium salts. liquid). When disinfected, different disinfectants can be used interchangeably.

Strengthen prevention and control to prevent moldy feed. Feed mold is caused by mold, mold caused by Aspergillus flavus, Aspergillus fumigatus. Accumulation or storage of feed for too long, when the temperature and humidity are appropriate, it will multiply bacteria, resulting in rotten feed. The methods for preventing mildew in feeds are: 1 Keep the feed dry, clean and air circulate. 2 sealed storage of feed, inhibit mold growth. 3 with calcium propionate (sodium) mold, 100 kg of feed plus 50 grams of sodium propionate or 100 grams of calcium propionate stir. In order to reduce the damage caused by flooding, feeds with milder mildew can be fed through virus-free treatment. The commonly used methods for detoxification include: 1 Washing to detoxify: Place moldy feed in the tank, add fresh water (preferably boiled water) The amount of foam soaked in the feed, and fully stir with a wooden stick, so after 5 to 6 times of cleaning, it can be used to feed livestock and poultry. 2 cooking detoxification method: the moldy feed into the pot, add water, cook for about 1 hour, then wash with water several times, remove the water can be used for feeding. 3 ammonia detoxification method: the moldy feed water content adjusted to 15% to 20% into the cylinder through the ammonia, sealed for 12 to 15 days and then dried, such as ammonia can be reduced after feeding .

Do a good job of vaccination and revaccination. Livestock and poultry shelters that have been flooded, various pathogenic bacteria and viruses are ubiquitous, and some are highly contagious. Therefore, vaccination must be done well before livestock and poultry are allowed to enter homes. In the course of vaccination, it must be carried out in strict accordance with the operating procedures. The phenomenon of missing needles and insufficient dosage should not occur, and vaccines requiring enhanced immunity should be replanted. It should also be noted at this time that sodium selenite and vitamin E should be added to the feed. The antioxidant properties of vitamin E can improve the body's immune system. The combination of sodium selenite and vitamin E can improve the immune system. It will be more pronounced.

After the flood, drinking water should be disinfected in order to ensure that livestock and poultry can drink clean water. The drugs used for disinfection of drinking water should use strong disinfectants with low toxicity and no residue. Two-chain quaternary ammonium salt disinfectants and disinfectants such as sodium dichloroisocyanurate and iodine can be used. At the same time, in order to enhance the physical constitution of livestock and poultry, and enhance disease resistance, water-soluble vitamins and electrolytes can be added to drinking water, such as quick fill -18, quick fill -14 and so on.
