Problems solved by technology

Although these treatment methods have achieved certain results, the existing problems are also obvious: (1) The injection of oxytocin should be seized when the cervix is ​​dilated and not contracted and locked, which is conducive to the discharge of the placenta, otherwise the placenta is still in the uterus Unable to excrete; (2) The milk produced by injection of antibiotics is inedible, and a certain period of drug withdrawal is required even after the cure; (3) Surgical stripping of the afterbirth requires high technical skills for the operator. If the disinfection is not strict and the operation is rough, it will cause trouble , can cause postpartum sepsis in severe cases

Abstract

The present invention discloses a feed additive for preventing postpartum retained fetal membranes of cows. The feed additive is composed of natural astaxanthin, yeast chromium, yeast selenium, vitamin E, sodium butyrate and a Chinese herbal medicinal additive (folium artemisiae argyi, radix astragali, white atractylodes rhizome and heartleaf houttuynia herb). The feed additive can regulate balance of reproductive hormone secretion in the perinatal cows, alleviates oxidative stress and oxidative damages suffered by the perinatal cows, maintains normal contraction ability of uterine smooth muscles, improves body immunity, thus prevents the retained fetal membranes of the cows, is also conductive for recovery of postpartum body condition of the cows, and improves reproductive performances and health levels.

Description

technical field [0001] The invention relates to a feed additive for preventing postpartum retention of placenta in cows and a using method thereof, belonging to the technical field of feed. Background technique [0002] Retained placenta usually means that the placenta has not been discharged 12 hours after delivery and remains in the uterus. It is one of the common diseases of cows after delivery. With the continuous development of large-scale breeding, the incidence of the disease is increasing year by year, with an average incidence rate of about 10-25%, but some cattle farms can be as high as about 50%. Retained placenta is very harmful to breeding cows. It not only leads to delayed postpartum estrus, decreased conception rate in the first mating and decreased milk production, but also easily secondary postpartum diseases, such as endometritis, delayed uterine involution and uterine prolapse. In production, many cows with retained placenta are eliminated due to infertil...
