First, fly control
There are many ways to solve the flies. The commonly used method is to spray flies or kill flies inside the house, but these methods do not fundamentally solve the fly problem. The following solution is mainly to eliminate the places where flies live and reproduce. This is the way to eradicate flies.
1. Add drugs to the material
Cyromazine is a highly effective insect growth regulator that has a killing effect on Diptera insect larvae, especially for the common fly larvae that reproduce in feces. Adding feed can make the fly be destroyed before the adult, this method has a good effect in many farms.
2. Resolve fly breeding sites
Another way to completely solve the flies is also to start with the eggs. The method is to cover the pig manure that is produced daily with a plastic sheet and seal the eggs of the fly insects in a plastic sheet. This does not need to be covered every day, because it takes a certain amount of time for the fly to transform from an egg to an adult, and changing the cloth once every three days is enough to kill all eggs. Note that when the cover is covered with a plastic cloth, it must be tightly closed. If there is a hole in the plastic cloth, it is necessary to use soil or other things to block it tightly and there must be no leakage. This method is the first supplement, because the pig farm feedstuffs are mostly full-priced feeds and cannot be added to the feed. The feed for pigs is the worst waste, pig manure and waste It is still a breeding ground for flies.
In many pig farms, there are still a lot of flies in the piggery after adopting the above measures. The reasons are often due to the lack of attention to internal health. In particular, feeds for suckling sows and piglets on the ground in the maternity ward are not cleared for a long time and become flies. The place where the breeding occurred; regularly checking the spread of the house and promptly resolving it, also reduced the number of flies to some extent. If the above three methods are combined, solving flies is a simple matter.
Second, mosquito control
Large mosquito net covers the entire pig house
This approach is more practical in small-scale pig farms. We have tested that if window screens are nailed, they can effectively block the entry of mosquitoes. However, because the screen sashes are relatively intensive, the ventilation inside and outside the house is seriously affected, especially in the high-temperature season in summer. The temperature inside the house is 2°C~3°C higher than that when the windows are ventilated. While solving the problem of mosquitoes, the high temperature of the house temperature, especially the long-term high temperature of the maternity ward, will reduce the sow feed intake. The high temperature of the pregnancy shed will also increase the number of stillbirths. The large mosquito nets will wrap the whole shed. The range of ventilation inside and outside is increased, and the ventilation effect is much better. If measures are taken to install mechanical ventilation facilities, this measure will be much better.
2. Dosing in Dead Water to Kill Eggs
It is the place where the mosquito eggs are controlled to kill the mosquitoes before they become adults. This method is more practical in areas with less water in the north, as long as they are placed on the places where there is standing water, such as drains, accumulated rainwater, etc., every week. Most of the mosquitoes' eggs will be killed; this will greatly reduce the number of mosquitoes in the pig house.
3. Mosquito repellent
Mosquito-repellent mosquito repellent methods are also considered in some pig farms. Because the smell of mosquito coils makes mosquitoes not dare to approach, mosquito-repellent incense sticks in pig houses can prevent mosquitoes from entering the pig house. Compared to the harm of mosquitoes to pigs, mosquito coils are The investment is still relatively much less.
4. Remove weeds
Weeds are often the place where mosquitoes inhabit during the day. If there are no weeds in the farm, there is no place for mosquitoes to hide. Eliminating weeds will make mosquitoes nowhere to hide, and it is also a way to reduce mosquitoes.
6. Install mosquito killers inside and outside the pig house to attract mosquitoes and kill them with drugs
In short, the above listed methods are some practical methods adopted by the pig farms. Each pig farm should be flexibly selected according to the actual situation of the farm, and the flies and mosquitoes should be put on the outside.
Many ways to eliminate flies and mosquitoes on farms
At present, the temperature difference between the north and the south is still relatively large. The temperature in the north is still relatively low in the morning and in the evening. Flies and mosquitoes have already appeared in some pig farms in the south. Both of them are always disturbing pigs, affecting the rest and growth of pigs, especially mosquitoes or Japanese encephalitis and Erythrocytes. We must prepare in advance to eliminate flies and mosquitoes and reduce their impact on pigs.
