How to reduce the stress response of piglets in long-distance transportation?

Stress prevention measures for transport piglets: 1. Strengthen nutrition. Feed rich in protein, vitamins and minerals should be fed before transportation 1 week to improve the immunity and resistance of piglets. At the same time, piglets should be fed with feed from the place of origin during transportation, and must be fed twice a day during long-distance transportation, and sufficient drinking water should be supplied. When you arrive at the feeding point, gradually transition feeding. 2. Try to create suitable traffic conditions. The optimum temperature for pigs is 15 ~ 23℃, and both overheating and supercooling will affect pigs. Therefore, when transporting piglets in summer, we should choose cloudy days and nights to avoid high temperature weather, and cover with sunshade facilities to prevent pig heatstroke. When transporting in winter, choose sunny weather to avoid the invasion of cold air, and there should be wind-proof and warm-keeping facilities in the car to prevent pigs from catching cold and getting sick; When transporting pigs, the vehicle speed should not be too fast and the brakes should not be too hard. Slow down carefully in roads, ditches and potholes to minimize the sudden crowding and shock of pigs. 3. Feeding anti-stress additives: vitamins. Adding vitamin C can promote the normal secretion of adrenocortical hormone, reduce physiological stress, help piglets maintain normal body temperature under heat stress and improve feed conversion rate. Vitamin B 1 participates in cell metabolism, especially glucose metabolism. Vitamin B2 is an important component of the nucleus. Vitamin E has the functions of protecting cell membrane and preventing oxidation, reducing the permeability of cell membrane and the release of inositol kinase in muscle cells under stress, thus preventing stress interference. Vitamin e can also improve the disease resistance of livestock. Vitamin K is an anti-stress agent, which can resist the stress caused by drugs. The second is electrolyte, such as sodium bicarbonate, potassium bicarbonate, potassium chloride and sodium chloride. It can maintain the acid-base balance in livestock and relieve heat stress; Thirdly, adding amino acids, adding various amino acid additives in the feed before and after piglet transportation 1 week, can supplement the protein decomposition of immune organs and immune cells caused by stress; The fourth is to add medicine. Because piglets are stimulated many times before and after transportation, in order to reduce stress, a certain amount of diazepam can be added to the feed when transporting piglets, but the dosage should be calculated according to the length of transportation time to prevent excessive addition of diazepam. 4, do a good job of immunization, it is recommended to use Odeman products. Generally most piglets are transported after weaning. Therefore, it is necessary to do a good job in the immunization of piglets from birth to weaning, such as preventing swine fever, piglet paratyphoid, edema and so on. , to ensure the health of pigs.
