Left displacement of the abomasum in dairy cattle: recent developments in epidemiological and etiological aspects.

The research with respect to displacement of the abomasum (DA) in dairy cattle is reviewed. Evaluated articles describe epidemiological and experimental studies. The occurrence is elevated with regard to breed, gender, age, concurrent diseases, environmental aspects and production levels as contributing factors and emphasis is placed on the effects of nutrition and metabolism. Reviewing the exp...

Milk yield and survival of Holstein-Friesian dairy cattle after laparoscopic correction of left-displaced abomasum.

The milk yield and survival of 91 Holstein-Friesian dairy cows that had had a left-displaced abomasum (LDA) corrected laparoscopically were compared with those of 193 control cows matched for herd, parity and calving date. Ninety per cent of the LDA treatments were performed within four weeks after calving. The risk of being culled during the whole observational period of at least three years w...

Nutritional risk factors in the etiology of left displaced abomasum in dairy cows: a review.

The transition period occurring 2 wk prepartum through 2 to 4 wk postpartum is the major risk period in the etiology of left displaced abomasum. The prepartum depression of intake and the slow postpartum increase in intake are risk factors causing lower ruminal fill, reduced forage to concentrate ratio, and increased incidence of other postpartum disorders. Uncomplicated ketosis, retained place...

Fluoroscopic observation of the development of displaced abomasum in dairy cows

To clarify the mechanisms underlying the development of displaced abomasum (DA), we repositioned DA in 12 cows by rolling and observed the course of redisplacement using X-ray fluoroscopy. Displacement of the abomasum was observed to follow three patterns: displacement to the left side of the abdominal cavity through the gap formed at the reticulum, atrium of the rumen and ventral sac of the ru...
