<p>This study aimed to evaluate the effects of two different treatment options for the correction of left displaced abomasum (LDA) on milk yield, hematological, electrolyte parameters, lactate and cortisol concentrations in primiparous cows. Twenty four Holstein cows were randomly assigned into three groups: cows treated with one-step laparoscopic abomasopexy (LPS, n=8), cows treated by left paralumbar omentopexy (LPT, n=8) and healthy cows (CON, n=8), matched by parity and days in milk. Blood samples were collected before (D0) and after (D0’) surgery, and 1 (D1), 3 (D3), 10 (D3) and 30 (D30) days following surgery. LPS and LPT cows at D0 as well as LPT cows at 30 d following surgery had lower milk yield than CON cows (P&lt;0.05), while the service period was higher in LPT than in CON (P&lt;0.05). WBC was lower at D0 as well as Hb and Ht at D0 and D0’ in CON group than those of LPS and LPT (P&lt;0.05). Hyponatremia, hypochloremia and hypokalemia at D0 and D0’ were observed in LPS and LPT. In addition, LPT cows had lower Na and Cl at D1 and D3 and lower K at D1 than CON (P&lt;0.05). Impaired hydration in LPS and LPT cows was accompanied by higher concentrations of lactate at D0, D0’, D1 and D3 (P&lt;0.01) and cortisol at D0 and D0’ (P&lt;0.01) compared with CON group, while LPT had higher cortisol at D0’ than LPS (P&lt;0.05). These results indicated that LPS has the potential to improve the convalescence period of LDA in primiparous cows.</p>

Blood samples were collected before (D0) and after (D0’) surgery, and 1 (D1), 3 (D3), 10 (D3) and 30 (D30) days following surgery. LPS and LPT cows at D0 as well as LPT cows at 30 d following surgery had lower milk yield than CON cows (P<0.05), while the service period was higher in LPT than in CON (P<0.05). WBC was lower at D0 as well as Hb and Ht at D0 and D0’ in CON group than those of LPS and LPT (P<0.05). Hyponatremia, hypochloremia and hypokalemia at D0 and D0’ were observed in LPS and LPT. In addition, LPT cows had lower Na and Cl at D1 and D3 and lower K at D1 than CON (P<0.05). Impaired hydration in LPS and LPT cows was accompanied by higher concentrations of lactate at D0, D0’, D1 and D3 (P<0.01) and cortisol at D0 and D0’ (P<0.01) compared with CON group, while LPT had higher cortisol at D0’ than LPS (P<0.05). These results indicated that LPS has the potential to improve the convalescence period of LDA in primiparous cows.
