Abstract
The study was designed to assess the effect of herbal, homeopathic, and hormonal drugs namely Janova, Sepia and GnRH-PG-GnRH on hematological parameters, resumption of ovarian cyclicity and conception rate in 40 postpartum anoestrus and 8 normal cyclic cows. The anoestrus cows were randomly divided into five groups as G0, GI, GII, GIII, GIV; 8 cows in each group. Group G0 (untreated anoestrus) and GV (normal cyclic cows) served as positive and negative control, respectively. All cows in GI, GII, GIII and GIV were subjected to dewormer and mineral mixture supplementation for 10 days, while group GII, GIII, and GIV were additionally treated with Janova (herbal heat inducer), Sepia (a homeopathic drug) and GnRH-PG-GnRH (Ovsynch) protocol, respectively. Different therapeutic protocols revealed variable and significant effects on most of the hematological parameters, except differential leucocyte count, before and after treatment. The values were also significantly higher in normal cyclic than anoestrus groups. The oestrus induction response in G0, GI, GII, GIII, GIV, and GV was 0.00, 50.00, 62.50, 75.00, 87.50, and 100.00 %, and corresponding overall conception rates of 3 cycles were 0.00, 75.00, 80.00, 66.66, 57.13 and 75.00 %, respectively. In conclusion, aforesaid therapeutic regimens have definite bearings on oestrus induction as well as on conception and can be used to manage postpartum anoestrus in cows.
Highlights
Postpartum anoestrus is one of the most prevalent reproductive problems in dairy cows despite technological advances in animal husbandry (Kumar et al, 2013)
This study was aimed to assess the effect of different therapeutic regimen on haematological parameters, resumption of ovarian cyclicity and conception rate in anoestrus cows
Kumar et al (1991) reported lower values of packed cell volume (PCV) in anestrous cows and heifers and postulated that the cyclic oestrus cows have a higher metabolic rate, which causes an increase in the production of RBC and this lead to increased values of other hematological parameters
Summary
Postpartum anoestrus is one of the most prevalent reproductive problems in dairy cows despite technological advances in animal husbandry (Kumar et al, 2013). This study was aimed to assess the effect of different therapeutic regimen on haematological parameters, resumption of ovarian cyclicity and conception rate in anoestrus cows.
