1. What are the reasons why sows don't eat before and after delivery? How to treat it?
Reasons why sows don't eat before delivery;
1, sow pregnancy reaction.
2. Sows are often constipated during the attack.
3. Prenatal feeding of sows is too large.
Reasons why sows do not eat after delivery:
1, caused by labor stress.
2. There is no effective feed reduction for sows before delivery.
3. The sow's postpartum triplet was not handled well.
Handling principle:
According to the reasons why sows don't feed before and after delivery, symptomatic treatment is carried out to eliminate pathogenic factors. The principles of comprehensive management are as follows:
Individual sows have a strong reaction to sow pregnancy, which is influenced by genetic factors, and sow constipation during pregnancy is common in most farms. In order to completely deal with the above two factors, functional additives for sows should be added to the feed to solve the problem, because it can effectively eliminate reproductive stress of sows, improve the balance of intestinal flora and improve the uterine environment, and fundamentally solve the problem that sows do not eat before delivery. Postpartum countermeasures for sows If pigs want to prevent and treat triplet diseases of sows, that is, eliminate inflammation, they should adopt practical and effective treatment principles, such as injection treatment and drinking water treatment after they can eat food, and then adopt the treatment principle of mixing materials. To eliminate inflammation, lincomycin is mainly used to treat inflammation, and multivitamins are used to ensure effective nutrition supply. After they are eaten, ampicillin is added to the feed to accelerate the elimination of inflammation, thus completely solving the problems in all production links of sows.
Second, why don't gilts go into estrus?
Cause of disease:
1, sow is overweight and underweight.
2. Sows are fed with fat pig feed.
3. Lack of feed nutrition, especially vitamins.
4, disease factors, sow reproductive dysfunction syndrome, parvovirus disease, Japanese encephalitis and other diseases.
5. Feed the sow with fat pig feed.
Handling principle:
In fact, in the production practice of raising pigs, it is very common that sows do not estrus. We should find out the real cause of the disease and treat it symptomatically. For obese and thin back-fat sows, it is necessary to master the normal body fat index of back-fat sows, which is generally around 120kg, which is the best estrus state. However, modern sows are mainly foreign ternary sows, which generally require higher feed nutrition level, especially vitamins. It is suggested that multivitamins should be added to feed to meet the reproductive needs of sows. Most of the pathogenic factors are diseases that often occur in sows, and most of these diseases are mainly vaccine prevention. The vaccine for blue ear disease should be determined according to the actual situation of your own pig farm. There will also be insufficient secretion of reproductive hormones in back sows, and the phenomena of inconspicuous estrus, single estrus and anovulation are all reproductive hormone secretion disorders. It is suggested that adding functional additives to the feed for conditioning can effectively regulate the secretion of reproductive hormones, which is beneficial to the normal estrus, ovulation and mating of reserve sows. Put an end to all feeding sows with fat pig feed!
3. Why do multiparous sows stop estrus after giving birth to one or two litters of pigs?
Cause of disease:
1. Postpartum inflammation of multiparous sows has not been completely eliminated.
2, estrogen secretion disorder and secretion disorder.
3, ovarian function lesions, etc.
4, mycotoxin poisoning, due to the intake of a large number of moldy feed.
5, lack of nutrition, feed nutrition is single, vitamins and other nutrients are helpless.
6. Lack of exercise and light.
7. A large amount of oxytocin is used before and during labor, which affects the secretion of follicle stimulating hormone.
8. Severe weight loss during lactation.
Preventive measures:
In the process of modern farming, especially some free-range households are more common, which will cause the above reasons because of poor handling of various farming links. For example, the feed of sows should be added with fungicides (mainly microecological fungicides) for a long time to eliminate mold factors. Postpartum inflammation of sows should be completely eliminated, and lincomycin and ampicillin are recommended as drugs. Oxytocin should not be used during or before delivery, and prostaglandin is recommended. Increase the exercise and illumination of sows, and add multivitamins to feed to meet the nutritional needs of new strains of sows. For the lack of reproductive hormone secretion in sows, it is suggested that functional additives should be used for sow conditioning 15 days, which can effectively solve the reproductive problem of sows.
Fourth, what is the reason for sow constipation during pregnancy? How to treat it?
1. Many roughage fetuses, such as bran feed, are added to the diet of sows.
2. The quality of sow feed is not expensive, and even pig feed is used instead of sow feed. Because the fertilizer contains a large number of antibacterial and growth-promoting drugs, constipation occurs due to the destruction of intestinal microbial environment and excessive water absorption.
3. Antiviral drugs and antibiotics are added to some inferior sow premix, especially when too many drugs are added to sow feed and lactation feed, which will also lead to sow constipation.
4. Insufficient drinking water and exercise.
5, caused by some inflammation and thermal diseases.
6. During the pregnancy of sows, with the gradual growth of the fetus, the uterus compresses the intestines, coupled with lack of exercise and drinking less water, and the feces in the intestines are dry in the intestines, leading to constipation in sows.
Preventive measures:
Sows during pregnancy must be fed with pregnancy feed. When they are taken to 10 days before delivery, they should be replaced with sow breastfeeding feed. Feed should not be used indiscriminately. 20% wheat bran should be added to the diet instead of wheat bran. If the situation is serious, adding 3% fried bran +2% oil, or choosing premix (small concentration) above 10% will alleviate this symptom. In order to completely solve this problem, adding functional additives and multivitamins to the feed during sow pregnancy can essentially solve the occurrence of sow constipation.
Hope to adopt, thank you!
