Influencia del peso corporal de la pantorrilla en la recuperación uterina con ecografía B

A través del examen de ultrasonido B del ganado, it can be known that the cow’s uterus recovery days and empty days are the smallest, the calf weight is between 40-45kg, the calf weight less than 40kg will take a longer time to recover the uterus, and the calf weight greater than 45kg will recover the uterus. The longest time. If the fetus is lighter, the uterus recovery time and the number of empty days are longer, it may be that the fetal development is not complete, and the maturity of the placenta of the mother is insufficient, which causes the placental separation disorder. If the fetus is too large during pregnancy, the probability of dystocia is relatively increased. Inadequate sterilization of midwifery, etc., causes uterine infection, which prolongs the number of days of uterine recovery and thus increases the number of days of empty pregnancy, indicating that larger fetuses have a tendency to extend the number of days of recovery of the uterus and increase the number of days of empty pregnancy.
Endometritis is a common obstetric disease in dairy cows after childbirth. In general, endometritis in dairy cows can be diagnosed with B-ultrasound. Endometritis can delay the first mating time and conception time after delivery, increasing the corresponding increase by 29-50 Días. Al mismo tiempo, the milk production of the diseased cows decreases, causing current and future double economic losses. According to the course and clinical manifestations of endometritis, endometritis can be divided into acute endometritis and chronic endometritis; if endometritis is treated in time, the prognosis is generally good. If not in time, dairy cows may become chronic or secondary to pyometra, hydrouterine, adhesions between the uterus and surrounding tissues, and salpingitis, which will eventually lead to poor recovery of the uterus and reproductive disorders. Por lo tanto, it is necessary to detect the uterus in time and effectively. Meningitis can be prevented with effective methods. Cows suffering from endometritis can also develop mastitis. The return of the endometrium to normal, cyclical changes, and perfect endocrine function are the ultimate goal of uterine recovery. The recovery of the endometrium directly affects the conception rate.
