Effect of B-Ultrasound on Cattle in Preventing Termination of Pregnancy in Dairy Cows
Reproductive obstacles caused by extensive management and overuse of dairy cows in production: due to extensive management, no lactation period, dry milk period, even regardless of size, mixed group feeding under the same ration formula, resulting in poor body condition of lactating cows, cattle The backfat thickness of lactating cows is poorly checked with B-ultrasound.
Breeding cows and dry dairy cows are too obese when examined by B-ultrasound, resulting in low reproductive function of the whole herd of cattle. Excessive utilization and blind pursuit of high milk yield lead to reproductive obstacles in dairy cows. There are cases in which milk production is increased by increasing the supply of high-protein concentrate feed. The result of this blind pursuit of milk yield can only cause reproductive disorders and digestive problems. Systemic diseases occur frequently.
Reproductive obstacles caused by improper breeding techniques of dairy cows: estrus observation time is wrong, insemination cannot be timely, and methods such as monitoring follicles with B-ultrasound are not used; artificial insemination personnel are not skilled in artificial insemination, artificially causing cervical Injury; lax aseptic operation, retained placenta failed to deal with in time, resulting in endometritis; Vaginal prolapse, etc. cannot be diagnosed and treated in time, which can directly lead to reproductive disorders, so it is necessary to use B-ultrasound for cattle for timely diagnosis and treatment. In addition, for dairy cows suffering from reproductive disorders, due to misdiagnosis or untimely treatment, the disease may aggravate, leading to irreversible reproductive disorders, and it is necessary to use B-ultrasound for cattle for preventive diagnosis of dairy cows. .
Strenuous exercise, mechanical collision, slipping and wrestling of pregnant cattle, eating grass with frost in autumn, eating mildewed forage for a long time, mycotoxin poisoning, sudden fright and misuse of drugs can all lead to abortion; death, leading to termination of pregnancy.
