Dog bleeding after artificial insemination ( ) is a common problem in commercial beef and dairy breeding herds. This article outlines how to perform the first-line treatment of choice for heifer bleeding following -related uterine trauma: the placement of a transvaginal hemostatic clamp and injection of intravaginal antibiotic solution. After the clamp is placed, the site of the uterine rupture can be determined, and local and systemic treatment should be administered. The author also discusses various techniques for controlling bleeding at sites other than the uterus. The importance of educating technicians about proper management of heifers with post- bleeding is highlighted. The author also recommends that all dairy cattle with an indication of uterine trauma be treated as described in this article. Heifers treated as described will not only have better fertility outcomes, but also a reduced risk of transmitting disease from the uterine trauma site to the fetus.

Bleeding from the uterus is one of the most frequent reasons for anesthetizing cattle in dairy and beef breeding operations. It can occur during estrus, post-estrus, or pregnancy and can result from surgical, traumatic, or traumatic ( ) procedures. Bleeding occurs when the endometrium, an area of thin tissue lining the uterus, becomes thin and breaks. The blood then collects and drains from the uterus (Figure 1). If untreated, uterine bleeding can lead to the loss of the fetus, or result in decreased fertility.

Hemorrhage is classified as primary or secondary. Primary hemorrhage is bleeding in the absence of other causes, such as uterine torsion or endometritis. The severity of primary hemorrhage can vary, depending on the amount of blood lost. A heifer that bleeds 4 L of blood over a 24-hour period, or one that bleeds 5 L of blood in 2 days, could both have a severe primary hemorrhage and need veterinary attention. Secondary hemorrhage occurs when the primary cause has been eradicated or treated, or when the primary cause was not the bleeding but the bleeding is associated with the primary cause. Bleeding is also classified as acute or chronic. Acute bleeding is not associated with or indicative of a cause, and usually occurs shortly after estrus, pregnancy, or an insemination. Chronic hemorrhage is bleeding that has been present for more than 1 week. This is typically associated with uterine torsion, endometritis, or other causes of inflammation. Bleeding from the uterus in cattle that are pregnant is called postpartum hemorrhage.

Because the uterus can bleed from numerous sites in the body, the location of the bleeding should be determined before initiating treatment. To do this, a number of approaches can be used, including auscultation, palpation, and visual examination. If there is no visual evidence of bleeding, the presence or absence of uterine contractions and the size of the uterus can be used to indicate a site of bleeding. It is important to note that although uterine contractions are a good indicator of a site of bleeding, they do not always indicate the location of bleeding. A site of bleeding can be determined if the uterus is soft to palpation or has no evidence of contractions, or if there is a pulsatile abdominal or pelvic mass.

There are a number of treatments available for the treatment of uterine hemorrhage in cattle, including intravenous (IV) fluids, intravaginal flushing with a pessary, uterine flushing with a pessary, uterine flushing with saline solution, local or systemic application of oxytocin, the placement of a transvaginal hemostatic clamp, local application of a hemostatic agent (adhesiolytic), local injection of antibiotics, and surgery to stop the bleeding. This article describes a technique that is the first-line treatment of choice for heifer bleeding following -related uterine trauma. This treatment includes the placement of a transvaginal hemostatic clamp and injection of intravaginal antibiotic solution. Although this treatment is the first-line choice for post- uterine trauma, other treatments, as described in this article, should also be considered.
