Causes, prevention and treatment of calcium deficiency paralysis in sows

Sow paralysis

Paralysis caused by calcium deficiency in sows is a common nutritional and metabolic disease in veterinary clinic. The disease mainly occurs in pregnant sows due to the lack of calcium in feed or due to improper matching of feed nutrients and insufficient intake of calcium in prenatal and postpartum period. The specific prevention and control measures of the pig disease are as follows:

I. the cause of the disease

The main results are as follows: (1) it is mainly due to improper feed collocation, poor feeding management, serious lack of calcium, phosphorus and other minerals in feed, and uneven feed nutrients lead to insufficient intake of calcium in pigs, which leads to sow paralysis.

(2) because the fetus in the belly of pregnant sows absorbs a large amount of nutrients from the mother, the maternal blood calcium concentration is greatly reduced, if the nutrients, especially calcium, phosphorus and other elements can not be fully replenished in time, then the occurrence of the disease will be induced.

(3) because postpartum sows absorb a large amount of nutrients from breast milk, the weaning time of piglets is too late, if nutrients can not be fully supplied, especially those feeds rich in calcium and phosphorus, then it will lead to a rapid decrease in the concentration of serum calcium in sows, thus inducing the occurrence of the disease.

Second, symptoms

In most cases, the body temperature was normal, the number of pulse and respiration was normal or slightly increased, occasionally the body temperature of secondary infection increased, pulse and respiration increased significantly, most of the sick sows swayed at the initial stage, the spirit was depressed in the later stage, and in severe cases, the hindquarters were insensitive to pain stimulation, the urine was yellowish or yellow, and the feces were dry and spherical. Decreased appetite and drinking appetite, mild symptoms can barely support for a while, but can not persist for a long time. When feeding, some sick pigs want to stand, but because their limbs are weak, their feet tremble constantly, they can stand unstable and scream, they can only kneel on their forelimbs and feed on their hind limbs. Most sick pigs are in poor condition. Some sick pigs can not afford to lie down for a long time, the coat falls off, the skin fester, and some sick pigs have ulcerated skin due to infection.

III. Preventive measures

The main results are as follows: (1) the incidence of this disease can be reduced by adding mineral-rich raw materials such as calcium powder and bone powder to the feed.

(2) in the feed, the ratio of calcium and phosphorus, 2:1 is appropriate, so that pigs bask in the sun, or supplement vitamin D.

(3) strengthen feeding and management, prepare feed scientifically and rationally, do not eat what you have, but need full-price nutrition.

IV. Treatment plan

(1) patients with mild illness should be injected intramuscularly with vitamin D gelatin calcium 4ml once every other day for 3-5 times. If the condition is improved, the dosage can be reduced as appropriate. For those sick sows with certain appetite and drinking appetite, bone powder and calcium powder can be added to the feed to strengthen nutrition. In order to prevent the occurrence of secondary infection, an appropriate amount of antibiotics can be used for symptomatic treatment.

(2) the sick pigs with severe condition, especially those who can't afford to lie down for a long time, have poor physique, have no appetite and have bedsores on the body surface, can be locally treated with antibacterial and anti-inflammatory drugs. For seriously ill pigs, they can be turned over manually, generally 4-6 times a day, to prevent the occurrence of bedsores. For sick pigs, 10% calcium gluconate 150ml can be injected slowly through ear vein, or 5% calcium chloride injection 20-50ml can be injected slowly intravenously, once a day for 3-5 days, as appropriate. For sick pigs with loss of appetite, the medicine can be given by intravenous drip, mixed with 5% calcium chloride injection 30ml and 5% glucose saline 1000-2000ml, or with calcium gluconate injection 1000-200ml intravenous drip. For seriously ill pigs, at the same time of intravenous administration, vitamin D glue calcium 2-3ml can be injected intramuscularly every other day for 3-5 times, as appropriate. In order to prevent secondary infection, antibiotics can be selected appropriately.
