The gilts are anti-**, and the pig farm solves the puzzle of 3 gilts.
Introduction. Recently, there have been many pregnancies of spare sows in the production process of pig farm staff, and although the feeding management has been strengthened, the pregnancy rate has not been improved. After killing 3 gilts that had been in estrus for a long time, we found out that the problem was a follicular cyst. Ovarian cyst is a condition in which pregnancy and litter numbers decrease due to abnormal estrus or inability to ovulate normally. In this paper, the factors, diagnosis methods and treatment methods of porcine ovarian cysts are reviewed, and the economic losses caused by pigs to pig production are summarized.
Effect of follicular cysts.
Follicular sacs can increase the rate of sterility during the childless period (infertile or return to estrus) and sterilization. At present, about 10% of adult sows in China are eliminated due to ovarian cysts, which seriously affects the healthy development of the entire industry. Due to the presence of ovarian cysts, the number of gestations and litters is significantly reduced, which seriously affects the economic benefits of pig farming.
Factors such as changes in ovarian structure, endocrine disorders, decreased frequency of apoptosis, diseases, genetics, nutrition, stress, etc., are all causes of ovarian cysts. The formation of ovarian cysts is the result of the combined action of body morphology, endocrine and other aspects.
- Follicular cyst test.
The diagnosis of follicular cyst is mainly determined by an ultrasound instrument or ruler. If the size of the follicle is in 2Follicular cyst is diagnosed if it is more than 0 cm and lasts for more than a week. Since the examination of ovarian cysts requires the skill of the surgeon and the precision of the equipment, it is necessary to perform the examination correctly.
Conclusion: Early diagnosis of ovarian cysts helps to detect problems early and make them effective**. The early detection of ovarian cysts can be targeted treatment, so as to improve the number of gestational and litters, and reduce the economic losses of breeding enterprises.
Diagnosis and treatment of follicular cysts.
Currently, the most common type of ovarian cyst is steroids. Clinically, LH, HCG and other cystic follicular luteinization are used, and then PCAFF-A and other drugs are used to remove the yellowing cysts in the cyst, so as to achieve curative effect. The results showed that sows with ovarian cysts could still achieve normal estrus and pregnancy rates after hormonal treatment.
For ovarian cysts, different ways can be used. In addition to hormones**, improving the nutrient content of feed, improving the living environment and strengthening prevention and control can all reduce the occurrence of follicular cysts.
Application of porcine follicular cyst in pig breeding.
Porcine follicular cyst disease seriously endangers pig production and the sustainable development of the pig industry. Ovarian cysts are the main cause of sow gestation and litter reduction, which seriously affects the economic benefits of pig breeding. However, due to the existence of ovarian cysts, it has caused the operating costs of hormones**, manual operation and elimination.
Follicular cysts are a major problem in pig farming. Therefore, the prevention and treatment of ovarian cysts is of great significance to pig production.
Brief summary. Ovarian cyst is a disease that seriously endangers pig production and seriously threatens the healthy development of pig production. In order to solve this problem, pig farms must take measures to improve the feeding conditions, improve the feeding conditions, improve the feeding conditions, and reduce the incidence of ovarian cysts. In addition, it is also necessary to diagnose and treat ovarian cysts, using hormones and other means to restore normal estrus and fertility.
While engaged in pig breeding, the author is also aware of the harm caused by ovarian cysts to pig production, and at the same time strengthens the health management and disease prevention and control of pigs. In continuous research and practice, it will contribute to improving the efficiency of pig breeding and promoting the healthy development of the pig industry. Although there are still many problems and challenges, we will achieve a stable development through unremitting struggle.
