Serum Levels of Neuropeptides in Cows with Left Abomasal Displacement

Experimental induction of left abomasal displacement: a new educational technique

The purpose of this study was to induce abomasal displacement to the left, and to let the undergraduate and post graduate students get used to the ping sounds of abomasum and other clinical manifestations. The procedure was carried out on eight young bulls, they were sedated and a 2 m flexible tube was inserted through the nasal canal into the rumen. By laparo-rumenotomy, 20 cm of the tube was ...

Role of serum pepsinogen in detecting cows with abomasal ulcer

Serum pepsinogen activity was determined in the blood serum of 126 clinically healthy cows by the method of Paynter. After slaughter the cows studied were classified into three groups according to established macroscopic changes to the mucous membrane of the abomasum: a group without changes, a group with ulcers and a group with other changes. The prevalence of the appearance of abomasal ulcers...

Abomasal Displacement in Cows - Measurement of Oxygen Saturation of the Abomasal Wall

The monitoring of intestinal oxygen saturation by means of a pulse oximeter is routinely applied in human medicine during surgery of the gastrointestinal tract to evaluate the disturbance of perfusion and assess tissue viability. To some extent, this technique has been applied in veterinary medicine. The purpose of this study was to test the technique in cattle and to describe the influence of ...

Study on the effect of left displacement of abomasum (LDA) on serum minerals and biochemical changes in dairy cows

Minerals and some biochemical parameters determined from blood serum analyses in left displacement abomasum (LDA) affected and healthy dairy cows to evaluate the effect of displacement abomasum on mineral status, energy metabolism and liver function. Samples were collected from 60 affected cows and 60 healthy control cows matched with cases, based on herd, parity, and stage of lactation. Concen...
