Effects of supplementation of Tinospora cordifolia to crossbred cows peripartum.

Guduchi (Tinospora cordifolia), a medicinal plant used in ayurveda, is well documented for its immunomodulatory properties. Since the crossbred periparturient cow is highly susceptible to various diseases that effectively reduces its reproductive performance postpartum we explored the possibility of enhancing the reproductive performance of crossbred cows by guduchi supplementation peripartum. A total of 15 pregnant Karan Fries cows were selected and divided into two groups: treatment group of 8 cows which were supplemented with guduchi at 60 g/day for 45 days prepartum and 120 g/day for 45 days postpartum and unsupplemented control group of 7 cows. Jugular blood samples were collected from all cows during the periparturient period for analysis of endocrine (progesterone, total estrogens and PGFM), immunological and hematological parameters. Incidence of retention of fetal membranes, endometritis, pyometra and calf mortality were higher in control group of cows in comparison to those recorded in treated group. The guduchi supplemented cows exhibited faster uterine involution (28 days vs. 42 days) and early commencement of cyclicity (37 days vs. 58 days; based on plasma progesterone profiles) in comparison to untreated control group of cows. Mean birth weight of calves from treatment group of cows was significantly higher than those from control group however no significant difference was observed in average daily body weight gain of calves in both the groups. A higher total leukocyte, lymphocyte, neutrophil count along with increased neutrophil lymphocyte ratio was recorded in guduchi supplemented cows in comparison to untreated cows although plasma total antioxidant activity was similar between the two groups. Prepartum plasma progesterone concentration was significantly lowered in the treated group however there was no significant change in peripartum plasma total estrogens and PGFM levels due to guduchi supplementation.
