Causes and control methods of sows
First, the cause of the disease
1. The proportion of concentrates in sow diets is too high. It has been observed that in pig farms where more roughage is fed, sows do not experience spasm before and after littering, which indicates that the occurrence of sows in sows is closely related to the proportion of roughage in the diet. According to expert analysis, it may be due to a higher proportion of roughage in the diet or a lower productivity of the pig, which has adjusted the ratio of calcium to phosphorus in the sow's diet.
2, calcium and phosphorus deficiency in sow diets. When calcium and phosphorus in the diet are deficient, sows will divert bone calcium and phosphorus before and after littering. Over time, it will lead to calcium and phosphorus deficiency in sows, especially in high-yielding sows, which are more likely to occur. After 20 days of farrowing, when the sow's lactation peaked, the condition mostly became serious.
3, concentrated feed cereals, beans and other large proportions. Phosphorus contained in cereals and beans is mostly in the form of Phytate Phosphorus, which is not only not easily used by pigs, but also can impede the absorption of calcium, causing severe calcium and phosphorus deficiency in the pig's body tissue, leading to sputum.
Second, the symptoms
Sows usually occur in prenatal days and about 30 days after childbirth, and individual sows experience lumbar numbness, numbness and cramps within a few days after delivery. Before sorrow, the sows lost appetite or did not eat, and the action was slow. The stools were hard and abacus beaded. They liked clear water, and there were eclosion phenomena such as arches, licking bricks, and feces, but the body temperature was normal. After the embarrassment took place, it was difficult to stand up. After standing up, he stood still and could not stand for a long time. When he was walking, his hindquarters wobbled and he was weak. During the drive, the hind legs were mopping and squeaking. Finally, they could not move.
Third, prevention and control measures
1, a reasonable mix of feed, and strive to balance dietary nutrition. According to sow feeding standards, it is necessary to make full use of local natural resources and try to feed as many green and green feeds as possible (not to feed too much at a time to prevent sows diarrhea) or high-quality hay powder, and supplement mineral feeds and additives. Sow productivity and prevention of sow crickets.
2. For pregnant sows and lactating sows, each day can feed 20 grams of high-quality bone meal and salt. If there is no bone meal, the proportion of feeds containing more phosphorus such as wheat bran and rice bran in the diet can be appropriately increased, and feeding green manure such as sweet vine vines can also be used to prevent and control sows.
3, the incidence of pigs, symptomatic treatment should be as soon as possible. Can use pig bone or other fresh livestock bones after similar to the treatment of microbial fermentation agent, after drying and smashing, stir the feed to feed the pig, feed 30 grams per head per day or so.
4, for severely ill pigs, can be used 5-10% calcium chloride injection 40-80 ml, an intravenous injection, is strictly prohibited intramuscular injection or leakage of the liquid outside the blood vessels, and with a high degree of liquor or 10% camphor alcohol smear the skin And artificial massage to promote their blood circulation and restore nerve function. While squeezing treatment, it is necessary to further strengthen the feeding and management. In winter, attention should be paid to keeping warm and cold, and in summer, it is important to prevent heatstroke and cool down.
5, feed digestible feed, use the Eco-fertilizer bed pig breeding, clean and health, greatly increased the disease resistance rate. In addition, the stress factors in the environment should be minimized so that sows can recover.
