Analysis of the effectiveness of surgical treatment methods for displacement of the abomasum in cows

This article shows results of a comparative analysis of therapeutic and economic efficiency of two ways of surgical treatment of displacement of the abomasum: the method of anchoring of the abomasum to the edges of surgical wound and the method of puncture of the abomasum with fixing it in the right position with the special suture with fixing. It is focused on the susceptibility to diseases of the cows of the Holstein Friesian breed, on the main anatomical and physiological features of the course of pregnancy and postpartum period of cows regarding the existence of a multi-chambered stomach. It is mentioned that the first step of the occurrence of a violation of the anatomical location of the abomasum is the moment when the uterine cavity releases from the fetus, but the scar is not filled enough. The abomasum displaces to the left hypochondrium because of the excess accumulation of gases. The main clinical symptoms of the displacement of the abomasum of cows, such as decreased appetite, decreased milk yield, increased body temperature, the sound of a drop falling in the left hypochondrium during auscultation, the ringing sound like “hit the ball” with percussion are mentioned in the article. The ways used in the work of returning the abomasum to the anatomically right position: the method of anchoring in the abomasum omentum to the edges of surgical wound and the method of puncture of the abomasum with fixing it with the special suture with fixing are described. The main steps of preparing and holding surgical intervention are listed. The animals' recovery time after two methods of surgical treatment are mentioned. The economic efficiency of the treatment of displacement of the abomasum of cows by the tested treatment schemes is defined. The conclusion about the most effective and cost-effective way of treating cows with postpartum displacement of the abomasum is made.
