What are the commonly used disinfection measures for cattle farms?

The commonly used disinfection measures for cattle farms mainly involve the mechanical removal of pathogens through sweeping, scrubbing, ventilation, filtration and other such methods. Although this method is common and frequently used, it cannot achieve thorough disinfection; as an auxiliary method, it must be used in combination with other disinfection methods.

Use sunlight, ultraviolet light, drying, high temperature, steaming and boiling and other methods to kill bacteria and viruses.

Using chemical agents to kill pathogens is the most commonly used method. When selecting disinfectant agents, the following should be considered: broad-spectrum germicidal activity, low effective concentration, fast action and good efficacy; second, being harmless to humans and livestock; third, stable properties, easily soluble in water, and not easily affected by organic matter and other physical and chemical factors; fourth, convenient to use, inexpensive, and easy to promote; fifth, odorless, no smell, and does not damage the items being disinfected; sixth, little residue or few side effects after use.

This method is commonly used to pile up contaminated manure for fermentation, using the heat of over 70°C generated when thermophilic bacteria multiply; after 1-2 months, pathogens such as viruses, bacteria and parasite eggs can be killed. However, this method is not suitable for diseases caused by spore-forming pathogens such as anthrax and blackleg; the manure from such diseases should be incinerated or deeply buried.

Carry out 2-4 times within one year, at least once each in spring and autumn. All utensils inside the cattle shed should be disinfected once a month.

Commonly used disinfection measures for cattle farms:

① For the cattle shed floor and manure and urine ditches, the following agents may be selected for disinfection: 5-10% hot alkaline water, 3% caustic soda, 3-5% Lysol solution and other spray disinfection, and use 20% quicklime milk to whitewash the walls.

② Rearing utensils, cattle pens, cattle beds, etc. should be scrubbed and disinfected with 5-10% hot alkaline water or 3% caustic soda solution or 3-5% Lysol; 2-6 hours after disinfection, rinse the feed troughs and cattle beds with clean water before putting cattle in.

③ After cleaning the exercise yard and removing all weeds, disinfect with 5-10% hot alkaline water or by spreading quicklime.

After tuberculosis, brucellosis or other diseased cattle are detected and removed from the herd, temporary disinfection must be carried out in the relevant cattle sheds, utensils and exercise yards.

① When a cow with brucellosis has an abortion, the aborted products and the contaminated sites and utensils must be thoroughly disinfected.

② The manure and urine of diseased cattle should be piled up at a place relatively far from the cattle shed and may be used as fertilizer only after biological heat fermentation.

③ The calving room should be disinfected once a month, and the delivery room should be disinfected once before and once after the calving cow gives birth.
