The influence of dystocia on the occurrence abomasal displacement in high productive cows

The purpose of the research was studying the prevalence of distortion at the previous calving pre-ceding the developing of pathologies of the maw in cows of German black and motley breed, the esti-mation of the role of animals having suffered dysto-cia as etiological factor of emergence of abomasal shift. It was established that dystocia was present at the last calving in 1/7 of the 35 heads with abomasal shift (in 5 of 35 heads). In animals who have suffered dystocia it is expedient to predict first of all developing of left-, but not right-hand patholo-gies of the maw. The prevalence of suffered dysto-cia at the last calving in cows with abomasal shift in early (from 1-10 days) and later (from 11-62 days) post calving period differed slightly: 15.7 and 12.5 % respectively. The prevalence of cases of existence of dystocia suffered earlier in all 35 cows with abomasal shift made 14.2 %. The cases of emergence of shifts of the maw in cows who had suffered dystocia at the previous calving throughout all studied period of time which passed from the previous calving (that is in both test groups), these cases were followed by wide age range (2.4-8.0 years) and weight range (477-750 kg) in test ani-mals. The cows with abomasal shift and previous dystocia had also considerable standard range (2.5-4.0 points of BCS). Dystocia which took place at the last calving in examined cows was not the only item and dominating etiological factor of ap-proach of abomasal shift, it cannot be considered as a reliable diagnostic factor, the marker of emer-gence of abomasal shift in animals both in early, and during later period after calving.
