Spring is the transitional season between winter and summer. The temperature varies widely. Coupled with the overcast and rainy days in the south of China and the dusty weather in the north, these climate characteristics determine that the pigs should take advantage of the situation and pay attention to feeding, management, and preventive health care.
Good management can significantly reduce the incidence and spread of disease
temperature control. In the springtime, cold stress should be prevented, because low temperature will make the piglets move slowly, and it is easy to induce diarrhea or excrement. Although the pigs and finishing pigs do not change obviously, under the temperature of 10°C or less, the pigs get hot. Increasing the number of pigs will increase feed intake in order to maintain body temperature, leading to reduced feed utilization. In addition, the temperature difference is too large or low temperatures can also easily lead to cold pigs, induced bacterial disease.
Control humidity. The pig house should be kept as dry as possible. If the pig is kept in a high-humidity environment (above 80%), the digestive system, respiratory diseases, and the incidence of skin diseases and parasitic diseases will increase. If the humidity is low (30% to 40%), the dust in the pig house is likely to fly, and the air quality is reduced. Adding cold weather in the spring will also lead to the spread and spread of respiratory diseases, causing greater losses to the pigs. At this time, if spray disinfection is performed, the humidity in the house can be increased to some extent on the basis of air purification, and the occurrence of respiratory diseases can be better prevented or reduced.
Control breeding density. The excessive density of pigs in the pig house drastically deteriorates the living environment of the pig. Raising under unfavorable environmental conditions, the continuous stress will weaken the protective response of pigs, induce digestive disorders, nervous excitement and other diseases, and reduce production performance. Overcrowding can also make pigs grow slowly, reduce feed utilization, and reduce indoor air quality.
Pay attention to environmental hygiene and strengthen ventilation. The large amount of excrement accumulated in the pig house, spilled or leftover feed, etc. can cause dust pollution and a large number of bacteria. Therefore, pig farms should clean up excrement in time and clean up and clean up the residual food in the tank and in the ground. Ventilation and ventilation is to discharge or dilute the polluted air in the house to provide sufficient oxygen supply. The temperature in spring is not very low, especially in the current situation of large-scale farming, this work can not be ignored, otherwise respiratory diseases will occur frequently.
Pay attention to disinfection and cut off the transmission of swine diseases
In pig farms, although there is no epidemic, there are sources of infection in the external environment. Pathogens will invade through air, feed, drinking water, and other pathogens. The disinfection and elimination of pathogenic microorganisms in the external environment and the cut-off of transmission routes can effectively prevent the occurrence and spread of infectious diseases.
In the spring, the breeding of pathogenic microorganisms has become active. It is necessary to thoroughly purify the farm and the surrounding environment. For internal disinfection of piggery, it is usually twice a week, once a day after infection, once a day. Disinfection method: After thoroughly cleaning and drying livestock and poultry houses, fully spray 3% caustic soda solution or 1 to 3000 toxin and other disinfectants.
