Old sows don't deserve to be kind, must be metritis or vaginitis? The sow will be in heat, but it is not always good enough. Most people encounter this problem most often think of metritis or vaginitis, but in fact there is a potential and neglected factor mycotoxins. The mycotoxin (F-2 toxin) acts like an estrogen, so the sow will have estrus, but when the sow's estrogen is too high, the sow cannot get pregnant and will not be able to keep it. What are the internal causes of hoof disease? The soft feet shut the sow on a slippery floor, causing strain on the feet and causing bone anomalies. When the sow has good lactation capacity or increased milk production, if there is no additional supplemental calcium and phosphorus, it will cause foot disease. Arthritis, which is caused by bacterial infections, must be disinfected on the ground to reduce the incidence. The cause of hoof cracking and hoof cracking is due to the lack of biotin in addition to the rough floor of the pig house. Pigs lacking biotin are prone to bruising. Sow constipation in the feed by adding high-fiber raw materials such as bran, why often the problem still can not be improved? In general, the sow diet contains slightly higher crude fiber than the hog, but the excreta is still harder than the hog. This is because sows produce udder edema, while pigs do not. Because sows land on four feet, a lot of moisture in the body will flow to the breasts, causing breast edema, so it will produce constipation. If you do not solve the problem of breast edema, only adding high-fiber raw materials such as bran sow diet, often constipation problems still can not be improved, and add bran will reduce the formula nutrient concentration, occupy the stomach space of the sow, Reduce sows intake of nutrients; bran will also produce a high amount of food to increase heat, not only will cause energy waste, so that the sow's body temperature increased, more severe analgesia after sow. Solution: Eliminate breast edema, adjust the balance of osmotic pressure in the body, promote intestinal motility and eliminate constipation. 40% of newborn pigs died due to lack of milk in sows. Did you pay attention? Forty percent of the deaths of piglets born are due to lack of milk in sows. Common causes include sows suffering from mastitis, breast edema, etc. According to the findings of anatomy, the occurrence of lactation in sows has edema in the breast tissue. Breast edema is an inevitable physiological phenomenon of sows. If you do not pay attention to it, it will often turn into mastitis, which leads to lack of milk. Prevent the infection of bacteria and viruses, pay attention to the disinfection of the delivery house. Solution: Eliminate breast edema, adjust breast lactation, promote normal lactation. Why does the last thing in a litter of pigs die from suffocation? The last thing in a litter of pigs died from suffocation. The reason was that the umbilical cord had already broken when the piglet was not discharged. If the sow was anaemia, tired and unable to contract, the piglets could not be discharged in time. The piglet was within 5 minutes. Will die from suffocation. Heat stress, anemia or disease are also common causes. The prevention method is to increase the amount of sow nutrition and prevent anemia; add excellent organic iron to the sow diet to increase the contractility of the sow's abdomen; reduce heat stress and reduce the content of crude fiber in the feed; pay attention to the delivery room Disinfection. The sow has been vaccinated, the pig is still sick, is the vaccine ineffective? The friends of the pigs must all know that it is very difficult to feed piglets that do not eat colostrum. This is because the newly born pigs have poor self-protection ability. They must obtain antibodies from the sow’s milk in order to resist pathogens in the environment. Therefore, if the sow lacks milk and has little milk or poor milk quality, even if the sow has been vaccinated, the pig is still squatting and still has a bristles. Therefore, it is not unreasonable why sows with high lactation ability are able to “bring pigletsâ€. Therefore, sows must increase feed nutrient content before they are born, and adjust breast lactation function to prevent breast edema. What should I do if sows are anorexia? Improve sows' anorexia, prevent sows from developing breast edema, avoid postpartum infection, and reduce sow's body temperature. Use a dripping device. Improve the environment, reduce ammonia and temperature. Reduce the amount of crude fiber in the sow's feed (eg bran) to reduce food intake. Use small meals and multiple meals and use wet materials. Increase the palatability of sow feeds. What is the relationship between the amount of lactation and the delay in estrus? Ovarian quiescence can cause sows to lose their estrus. When the prolamine content in the sow is high, the amount of estrus can not be increased. When the sow's lactation level is very low, the body will secrete more prolactin to stimulate the secretion of milk, so that after weaning, the estrus will be delayed or not obvious, sows with good milking ability, as long as nutritional supplements are properly On the contrary, sows that are poorer in lactation are more susceptible to heat. Sometimes body fat is not enough. If a sow loses too much weight during lactation (eg, the amount of lactation is increased and the concentration of nutrients is not increased), the sow will cause no estrus after weaning, and should increase caloric energy and not limit feeding.
