EFFECT OF DIFFERENT THERAPIES IN EARLY POST PARTUM PERIOD ON FERTILITY OF HF COWS

Abstract

This study was conducted on 24 normally calved HF cows of university farm divided into four
groups; each of six animals. Group I served as control-- only Al; whereas Group It was treated with
Oxytetracycline (2 g Uroblex ob let) intrauterine on 2nd day postpartum after expulsion of placentc:1 +
GnRH (lnj. Receptal) 50th day postpartum+ Al; Group Ill - Oxytetracycline + GnRH + Herbal Bolus
(Bioheat) orally 50111 day postpartum +Aland Group IV - Oxytetracycline + GnRH + non-surgical ET 71h
day post~estrus. The overall mean levels of plasma progesterone, glucose, total protein, total cholesterol
and total triglycerides on 501r, day postpartum were 1.80 ± 0.46 ng/m/, 32.54 ± 5.48 mg/di, 4.48 ± 0.41
g/dl, 57.09 ± 8.88 mg/di and 182.96 ± 20.56 mg/di, respectively. Significant differences (P < 0.05) were
observed between groups for plasma P4 and triglycerides levels. The level of progesterone in control
group was significantly higher than the treatment group (3.25 ± 1.31 vs 1.32 ± 0.41 ng/ml). Control
group showed significant variation from the treatment groups for most metabolites, but within the
treatment groups there was no significant variation. Percentage of animals conceived in control and
treatment groups were 33.33, 83.33, 100.00 and 50.00, respectively. The pooled conception rate of all
treatment groups [77.78% (14i18)J was higher than the control group [33.33% (2/6)]. The animals of
treatment group having lower plasma prog0stercne concentration on 5Q1h day postpartum responded
well to the hormonal (GnRH) and herbal (Bioheat) treatments and had better conception rates than the
control group. The animals having higher blood glucose and lower triglycerides concentration also
conceived earlier.
