摘要
With the enlargement of intensive feeding scale of dairy cows and improvement of milk yield, the incidence rate of displacement of abomasum in dairy cows increases gradually in recent years. Previous researches have shown that VFA in abomasums can significantly inhibit the shrinkage of smooth muscles of abomasums and lead to atony of abomasums, but the specific regulatory mechanisms are still unclear. In this study, the expression of VFA receptors GPR41 and GPR43 in cow abomasums were detected by PCR method, and the fragments were consistent with the excepted sizes. This study provided theoretical basis for the pathologic mechanism investigation, prevention and treatment of displacement of abomasum in dairy cows.
