What is the impact of continuous haze weather on livestock growth? What should we pay attention to in management? The reporter consulted Wei Xiangfa, a researcher of the Institute of Animal Husbandry at the Provincial Academy of Agricultural Sciences and a researcher at the Institute of Poultry.
Pig: strengthen disinfection
Cheng Jianguo said that the impact of hazy weather on pigs is mainly in three aspects: Light deficiency affects the intake and breeding, poor air quality affects ventilation, and ultraviolet light reduces the number of pathogens.
Specifically, the lack of light directly or indirectly affects the performance of pigs, such as mating and sows reared in dark and light conditions, the ovary weight is reduced, the conception rate is significantly reduced; for feeding pigs For light, lack of light directly affects the effects of eating. During hazy days, large amounts of dust particles, smoke particles, and salt particles float in the air, creating a dilemma for ventilation in pig houses. This will inevitably severely affect air quality in the homes. Pathogens may adhere to dust particles and cause respiratory tracts in pigs. disease. In the absence of sunlight during hazy weather, ultraviolet radiation is naturally insufficient, which leads to an increase in the number of pathogens in pig houses. In addition, when the weather is high in the fog, the air is dry, and it is necessary to pay attention to it during management.
Against the above hazards caused by hazy weather, Cheng Jiang made the following recommendations:
Strengthen pig house disinfection. At the same time as routine disinfection, increase the number of air disinfection to reduce dust levels and suppress the spread of pathogenic bacteria in the air. When disinfected, it can be sprayed, atomized or sprayed with a hot mist or fumigated. The common feature of disinfectants is that they have great harm to humans and animals. The ratio of formaldehyde to glutaraldehyde and glutaraldehyde to quaternary ammonia is cheap and effective. It is a good choice in the current situation. In terms of disinfection methods, smaller pig houses are recommended to use spray; large and high pig houses are suitable for use with aerosols; fumigation can only be used for sterilisation; hot mist is suitable for large pig houses, although it is noisy, Uniformity is good.
For the piggery, the humidity is different and it should be handled at any time. In the foggy days, the air is high in humidity; when it is in the sky, the air is dry. The relative humidity of piggery is 50-70%. Below 40% air is too dry and dust in the air increases. In the case of low temperature and high humidity, the pig's daily weight gain can be reduced by 36%, and the weight gain per kilogram can be increased by 10%. Therefore, when the air humidity is high, it is necessary to properly use dehumidification of quicklime, desiccant, charcoal, etc.; in the case of excessive air humidity, control the frequency and water consumption of the piggery, etc.
Chicken: Proper ventilation
As far as the pig house is concerned, the chicken house (except for free-range chicken) is closed, and ventilation is particularly important. Wei Xiangfa said that in the weather with bad air quality in the hazy days, the biggest threat to chickens is respiratory diseases. If you do not handle it properly, you have respiratory illness. For chicken health, it is the dominoes that have been toppled.
For the ventilation of different houses, Wei Xiangfa put forward different suggestions: For young chicks, pay attention to insulation, because large chickens in the chicken house have a small amount of respiration. In this kind of weather, air quality can be guaranteed without opening windows for ventilation. For late-growth broiler chickens, proper ventilation is required to ease the air quality in the homes and reduce the ammonia concentration in the homes; for the broiler houses, the skylight should be opened to avoid opening the air blower.
In addition to ventilation, Wei Xiangfa also proposed the following suggestions in order to avoid inducing chicken respiratory diseases and improving indoor air quality:
Use vitamins to enhance chicken immunity. Vitamin A plays an important role in maintaining the normal growth, development, reproduction, and immune function of laying hens. If smog is injected into chickens with Newcastle disease vaccine at this time, the addition of sufficient amount of vitamin A can enhance the immune effect. If it is added in the full-priced formula, the appropriate amount of vitamin A is between 9000IU/kg-12000IU/kg. Use vitamin C to help the body resist stress. In the adverse conditions of high temperature, cold, transportation, and stress, adding vitamin C to the flock can reduce the reaction to some extent.
Reduce the humidity in your home. Pay attention to whether the pipes in the chicken house run leaks, etc., and repair them in time. This is especially important for all broiler houses, especially broiler farms in fermentation beds. Minimize unnecessary spraying, watering, and disinfection without chicken.
The conditional egg house is artificially heated.
In addition, Wei Xiangfa also reminded farmers that under the hazy weather, stocking chickens must be housed in their homes to minimize outside activities.
