In view of the rapid development of pig production, the number of swine diseases is increasing, and the prevention and control measures are also very complicated. In order to solve the problem of disease prevention and control in pig farms, it is not enough to pay attention only to considerations such as drug care, vaccine immunization, and environmental sanitation. The author believes that the most important thing is feeding and management, and the key is to raise the management of pigs. Treatment of stress. Excessive stress factors “stimulate†the pig body and cause the pig's body resistance to decline. The conditions of the pig farm, such as E. coli disease, asthma, parathyroidism, etc., can occur “endogenous†or "Exogenous" infections, over time, combined with other factors, pigs will have different degrees of disease. Here's a case about the death of a pig due to stress from management negligence. Once there were farmers, his family of 160 weaned pigs performed abnormally in recent days. They quivered and trembled, and their feed intake decreased. They all went red or white and they died on the same day; they immediately observed and detailed the scene. inquiry. problem dicovered Question 1: Low temperature and high humidity. The pig house is a newly built pig house, and the position is in the upwind direction. The temperature inside the house is very low. It is estimated that the temperature is about 11°C. The humidity is also relatively large. There is very little litter on the cement floor, so the pigs will get together. Question 2: Herd transport stress. The client said that his pigs had a very good growth condition before being transported. They had bright furs and “great greedâ€. They fed some electrolytic cubes before transshipment. It was better two days before the transfer, but problems began to appear on the third day. Now. Question 3: There is a garbage pit 200 meters away from the pig house. In addition to domestic garbage, the vaccine also found empty bottles of swine fever, pseudorabies and paratyphoid vaccines. Question 4: There is no clear boundary between the culture area and the living area. There are many small floating objects on the disinfection pool at the gate. Question 5: The performance of the affected pigs: Feed intake decreased, individual pigs stopped feeding, depressed spirits, trembling, red skin, individual pigs with white skin, constipation, yellow urine, and nostrils with white foamy discharge The eyes are in tears, and the conjunctiva is red or white; the amount of water in the pigs is still quite large. Deaths and eperythrozoontosis were observed only in necropsy pigs. Diagnostic results and measures The disease on the farm is mainly caused by stress. Due to the neglect of pig farm management, the low temperature and high humidity in the pig house, coupled with improper handling of the transshipment, resulted in decreased resistance of the pig's body and the occurrence of swine cold and eperythrozoon diseases. Measure 1: Strengthen the heat preservation and cold protection, increase the temperature inside the pig house, reduce the humidity, and lay some thermal insulation litter inside the pigpen. Measure 2: Drink warm water in the whole group. Add water to the veterinary (1000 liters of water per 500ml) and vitamin C (300g per ton of water). Measure 3: Mix the whole group, add 1500 grams of anti-virus powder I per ton of feed, 600 grams of constant Ford, 250 grams of doxycycline. Measure 4: Intramuscular injection of mixed red bow chain (5 ml per 50 kg body weight) and Vajra throat threw (10 ml per 50 kg body weight). Measure 5: "Rectification" of the farm. The disinfectant should be changed once a week in the disinfectant pool. The garbage pit should be buried. All kinds of domestic garbage, including used vaccine empty bottles, must be transferred to a place away from the farm 500 meters away. The empty vaccine bottle should be buried deeply; living area Separate from the production area. Measure 6: Pay attention to the management of pig farms, especially the stress caused by feeding and management. In addition, measures such as environmental health, drug care, and vaccine immunity must also be scientifically formulated and implemented.
