Did the sow you feed have constipation?
Sow constipation is very harmful and can lead directly to sows without milk after birth. Sow constipation can also lead to birth weight of the pig.
Causes of sow constipation
Physiological causes. From the sow to late pregnancy, as the age of pregnancy increases, the growth of the fetus is accelerated, oppression of the rectum is formed, rectal motility is slow, and constipation is formed, especially in the sows where there are multiple birthplaces and sows born with major births; in addition, from the pregnancy one From the time of diagnosis of pregnancy to the end of breastfeeding, the sows used to spend their time in the monomer limit bar and the farrowing bar on most farms. Lack of exercise caused the sows to have lower intestinal function and dry stools, causing constipation.
Insufficient drinking water. Lack of water or insufficient flow rate in the drinker can cause sows to be deficient in water, and the sow's drinker flow rate should not be less than 1.5 liters/minute. Lack of drinking water can also result in underfeeding of nursing sows.
Heat stress. In summer, the temperature of the pig house is too high and the sow's body temperature rises accordingly, causing constipation.
Overfeeding restrictions. Water in the large intestine is excessively absorbed and constipation occurs.
The occurrence of infectious diseases, such as blue ear disease, swine fever, etc.
Mycotoxin poisoning. Feed mildew, especially aflatoxin poisoning, causes sow constipation or diarrhea.
Measures to prevent constipation in sows
Strengthen management. Conditioned sows in pregnant pig farms can be reared in large areas, which reduces the incidence of constipation and meets animal welfare requirements.
Feed nutrition balance. It is necessary to fully consider the balance of energy, protein, minerals, vitamins, moisture, and cellulose in the sow's different physiological stages, and to use more easily digested and absorbed raw materials to prepare balanced feeds based on this level. The probability of feed retention in the digestive tract. Weijia sow material T440 (or 5440A) and T540 (or 5540A) adopt the latest amino acid balance technology, which can fully reduce the protein in the diet while ensuring the nutritional needs of the sow and achieve the purpose of reducing excrement.
Do a good job in the immunization of vaccines to reduce the incidence of infectious diseases. At the same time, use immune function regulators --- vitality yuan, enhance resistance, and improve vaccine effectiveness.
Supply sows with clean, adequate drinking water. The flow rate of the drinking fountain should be 1.5 to 2.5 liters per minute. Adding Kasugasu to drinking water during stress can increase the anti-stress resistance.
The quality of good raw materials, to prevent the inflow of ultra-high moisture and mildew raw materials, and add mold in the feed.
For sows that have developed constipation, biological products such as Runshengkang can be added to the feed.
Did the sow you sowed die from asphyxiation due to a long period of labor?
When the sow is produced, the production interval of two pigs exceeds half an hour can be considered as the production process is too long, and the long production process greatly increases the risk of suffocation of the pig.
Reasons include
Physiological causes. The primordial sows and old sows are incapable of uterine contraction, resulting in prolonged labor.
Sow constipation or pig weight is not uniform.
Sows produce insufficient energy to cause contraction of the birth canal.
Sows are highly nervous and sensitive during childbirth, which makes them restless and prolonged.
Prevention
More than 220 days of gilt sows weighing more than 125 kilograms were bred. Sows with more than 7 births are generally excluded unless they have excellent results.
Before and 7 days after sowing, each sow in the feed is added with two heads and mixed and fed to supplement energy and strengthen the body. It can also effectively improve the condition during production and shorten the birth process.
Feed the sow's nutritionally balanced diet to meet the normal nutritional needs of the sow. Weijia sow material T540 (or 5540A) is supplemented with nutrients and special nutrients that promote reproductive function, increase reproductive performance of sows, shorten labor and promote postpartum uterine recovery. Or the sow is replenished with two heads three days before the sow’s arrival to provide sufficient energy for the sow.
Do preventive health and immunization work to reduce the incidence of reproductive disorders. Add Asparagus + Runshengkang + Vitality Elements to the feed.
Give the sow a quiet production environment, stop noisy people and send people into the delivery room.
Chlorprostinol can be injected in the morning 1 day before the expected date of sow so that sows can be delivered at the same time, and the duration of labor can also be shortened.
Massage the sow's breasts during childbirth and give birth correctly. Massage your nipple vertically with your fingertips and then release it.
3 days before the start of production, add Kangtai, until the 3rd day after childbirth, produce Kangtai blood stasis, warm the pain, prevention and treatment of postpartum blood deficiency, no placenta, lochia is not the net, uterus?蹋 å²£åŸ å²£åŸ è‹«ç›¥ 苫盥 苫盥 苫盥 苫盥 ã¤ ã¤ ç © ç © ç © ç © ç © ç © ç © ç © ç © ç © ç © ç © 】 】 】 俳 ; ; ;?
Sow without milk syndrome
The sow arrhythmia syndrome shows sow postpartum lactation deficiency or lack of milk. This will lead to slow growth of the pig, poor physical fitness, increased drug use rate, weaning weight, etc., directly affect the fattening effect of the later period.
the reason
Physiological reasons. The replacement of gilts is premature because the sow's mammary gland development is not yet complete, leading to the occurrence of sow syndrome.
All kinds of causes of sows postpartum feed intake is insufficient. For example, constipation leads to an increase in toxins in sows, anorexia or no food; sows are overly obese, resulting in gastrointestinal dysfunction, causing inedible food, which ultimately leads to the occurrence of sows without milk syndrome.
Improper feeding. There was no reduction in the sow's prepartum labor, resulting in a sudden decrease in the abdominal pressure after the sow's delivery, causing no postpartum milk.
Mastitis. The disinfection of midwifery is not complete, the poor sanitation of the pig house, the breeding of bacteria, resulting in the occurrence of mastitis, causing anorexia or not eating, resulting in sows alopecia-free syndrome.
Occurrence of certain infectious diseases, such as blue ear disease, swine fever, etc.
Prevention
The gilts were more than 220 days old and weighed more than 125 kg and were bred in the second estrus.
Strengthen management and improve the feeding environment. According to the sow's body condition and physiological stage, the energy, protein, amino acid, and vitamin balanced feeds should be used to meet the nutritional needs of the sow and prevent it from becoming too fat. Weijia sow material T440 (or 5440A) and T540 (or 5540A) adopt the latest amino acid balance technology, supplemented with nutrients and special nutrients that promote reproductive function, provide adequate nutrition, and promote breast development and milk secretion.
Reduce the occurrence of constipation according to the prevention and treatment of sows constipation.
Strictly follow the established immunization procedures to reduce the occurrence of infectious diseases.
If sows need midwifery, strict and detailed disinfection should be performed.
For the pigs suffering from mastitis, long-acting ceftiofur was injected into the diet. Sultanol was added to the diet. At the same time, it was added to the breast or the breasts to reduce the swelling, detoxification, blood circulation, swelling, and pain relief.
The Bao Jia powder is applied directly to the sow's vulva, which acts as a dry and antibacterial agent.
Reproductive system inflammation
The genital inflammation of sows mainly refers to metritis, mastitis, sows arrhythmia syndrome. These diseases are closely related in pig production. Only by adopting comprehensive prevention and control measures can the purpose of prevention and control be achieved.
Strengthen management and keep the sow's living environment clean and tidy.
According to the sow's body condition and physiological stage, feeding nutritionally balanced feeds to meet the sow's nutritional needs, so that the sow always maintain a good body condition, to ensure the sow's sufficient productivity, to minimize the cause of the midwifery Damage to the reproductive system.
Seven days before and after sow giving birth, add asparagus plus vitality element to the feed, and add the product to produce Kangtai 3 days before and after childbirth to prevent the occurrence of reproductive system diseases.
Drinking water to add Jia Su.
On the day of delivery, the long-acting ceftiofur + animal power source was used for two days.
Before giving birth, the nails should be cut short, polished, and thoroughly disinfected before giving birth. After the birth of childbirth, long-acting ceftiofur and other drugs should be injected immediately to prevent the occurrence of endometritis and vaginitis.
Sows do not have estrus after weaning
After the weaning, the estrus can be bred for 5 days to 7 days. However, in actual production, some sows were found to have no signs of estrus after 10 days or even more than 15 days after weaning. Not only reduces the utilization of sows, but also increases the cost of feeding.
the reason
Age fetal times. Under normal circumstances, about 30% of gilts have been estrus for more than 7 days after weaning.
temperature. The high temperature delayed the estrus after weaning of sows, and the morbidity of weaned sows in July-September was higher than other times. Young sows were particularly noticeable, and some were not estrus for as long as several days after weaning.
nutrition. Insufficient energy and protein intake during sow feeding, or excessive weight loss due to low feed intake, results in no estrus after weaning.
The occurrence of diseases such as endometritis delayed sows after weaning.
Precaution
After sow weaning, short-term, high-feed feeding methods are used.
Reasonable sow parity structure: 3 to 6 tires accounted for 70%, 1 to 2 tires accounted for 17%, the other for the old sow.
The right temperature. The optimum temperature for sows is 18°C ​​to 20°C. In particular, summer heat-reduction and cooling work should be done. Air-breathing homes and breeding houses can be spray-cooled or water curtain-cooled. Diverting houses can be cooled by dripping water and cooled by water curtains.
Sows feed high-energy, high-protein diets during lactation to reduce weight loss during lactation and ensure that sows are estrus promptly after weaning. Wei Jia nursing sow material using the latest nutritional balance technology, can minimize the sow's lactation weight loss.
Before and 7 days after the sow's sow is fed, 50 grams of two heads are added to each meal, and the mixture is fed to feed one pig per day.
Do 7 days of prenatal and postnatal health care to prevent the occurrence of endometritis and other diseases. Add Asparagus + Vitality to the feed, and add 3 days after prenatal and postpartum to produce Kangtai. On the day of delivery, the long-acting ceftiofur + animal is used for two days.
For the treatment of estrus-free sows
Physical method. Bars, hunger or excellent feed, boar aphrodisiac, polyculture with estrus sows, exercise, etc.
Drug methods. Adding aphrodisiac in the diet can also use cloprostenol, chorionic gonadotropin, pregnant horse serum, estradiol benzoate, and the like.
