Abstract
Daily drenching of propylene glycol to buffalo cows in early lactation was used
aiming at improving the reproductive performance through increasing plasma glucose
and insulin . Twenty two buffalo cows were assigned to two groups (treated and
control). Treated buffaloes were given a daily oral dose of propylene glycol from day
7 to day 40 postpartum. Plasma concentrations of glucose. insulin, and urea were
measured once weekly during 2-9 weeks postpartum. and progesterone
concentrations were measured twice weekly from 2 to 13 weeks postpartum.
Propylene glycol increased plasma glucose concentrations in treatment group (63.06
i 0.34 vs. 6016 t 0.67 mgrdl), and increased insignificantly insulin concentrations in
treated buffaloes compared with control group. Plasma urea nitrogen (PUN) in the
control group tended to be higher than that in the treatment group (37.21 i 0.23 vs.
35.9? 2 0.16 mgl‘dl}. The interval from calving to first ovulation in the treatment
buffaloes were less than that in the control buffaloes. Days open period was less in
treated group than that in the control (65.45 i 7.5 vs. 8181 t 8.2 days). Conception
rates at 50 days postpartum were 36% in the treated group and 18% in the control
group. These results demonstrate that. administration of propylene glycol may
improve ovarian function during early postpartum period in buffalo.
