(1) Piglets born with poor sow breeds are necessarily slow-growing. Therefore, high-quality, high-yield sows should be selected and poor-quality sows should be eliminated.
(b) Weaning is not scientific. At present, farmers tend to adopt pig weaning methods more than once, that is, l litter pigs originally used the mother as the center and their siblings live together. The stable and comfortable living environment suddenly changed, which affected the appetite of the piglets. It is difficult to adjust to gain weight. It is reasonable to reduce the number of sucklings of piglets until they are fully weaned within 1 week before weaning, and to frail piglets for a few days. This method is very beneficial to the growth of piglets.
(3) The time and quantity of feeds are unreasonable. Piglets are not fed in time in the middle and late stages of lactation, and they cannot eat well after weaning, which affects the growth and development of piglets. Therefore, experts suggest that feed should generally be fed once a week after the birth of the piglet. Because the sow's milk production decreases with the increase of the piglet's age, piglets should be fed as early as possible to compensate for lack of nutrients caused by insufficient milk in the sow. Start with the principle of fragrant, sweet, crisp and easy to digest.
(4) The environmental conditions have changed too much. After weaning piglets, it is usually a pig lap, which can not adapt to this lonely life within a short time.
Especially in the cold winter weather, it is difficult to eat well, and it is easy to have a variety of diseases and even death. Therefore, when buying pigs, try to ask as many questions as possible and create a comfortable living environment for the piglets as much as possible. Changes should be made gradually.
(five) care is not careful. Farmers now raise pigs, most do not pay attention to environmental hygiene, and some pigs eat, eat, sleep, defecate in the same place, plus the housing is not cleaned, litter does not often change, resulting in environmental pollution, poor sanitation, pigs The body is very dirty, especially in the winter and spring, the environment is harsh, it is easy to cause disease, seriously affect the health of pigs, extremely detrimental to growth and development. The correct approach is based on pigs eating fast and good, with 3 to 6 heads in a l-lap, so pigs compete for food, grow fast, and do a good job tuning work to make it a fixed point of eating. Site-specific excretion of urine, sleep at a certain point, and maintain the sanitation of the shed. Careful attention to the management of sows and piglets is beneficial to the growth of piglets.
(6) Poor feeding methods. Some farmers think that pigs are weaned and can reduce concentrates, and feed less water. The number of daily feeds is reduced from 6 to 8 times before weaning to 3 times a day. Sudden changes in feeding methods are very detrimental to the growth and development of piglets. The correct approach is, do not suddenly reduce the nutritional standards, so that the gradual transition of quality and quantity of feed, fine, green, rough feed should be reasonable, there are grazing conditions can gradually reduce the fine material, the number of feeding can be gradually reduced, but must be based on The condition of your own home and the development of the piglet.
(7) Problems in disease prevention and castration. Farmers buy more pigs than bazaars and conduct epidemic prevention and castration at the time of purchase. In this way, the three factors of weaning, epidemic prevention, and castration were all added to the piglets, so that the piglets could not recover over a long period of time, seriously affecting the normal growth and development of the pigs, causing the pigs to grow slowly and further to form a stalemate. Pigs, causing undue economic losses. A variety of vaccines were injected according to the local epidemic before the pigs were 1 month old. Common diseases such as piglet dysentery should also be promptly treated. For piglets that do not keep pigs, boars can be around 3 weeks of age, and gilts can best go around 5 weeks of age. In order to prevent the pigs that have the greatest harm, piglets vaccine may be given once a week after the baby is born and then injected once. The erysipelas vaccine can be injected after weaning.
