Peripartum Supplementation of Rumen Protected Choline and Fat and Se+Vit E in Gir Cows Economically Improves Endocrine Profile and Reproductive Performance

Background: The negative energy balance around calving and in early lactation is the major cause of increased incidence postpartum metabolic disorders, reduced milk production impaired reproductive performance. This study was aimed to evaluate effect rumen protected choline, fat supplementation Vit-E selenium injections on plasma endocrine profile, productivity, fertility economics transitional Gir cows. Methods: Forty advanced pregnant multiprous cows an organized farm were randomly distributed into five equal groups (T1 T5; n=8 each) fed managed individually from 30 days prepartum till 60 postpartum. Cows T1 (control) group basal diet, while treatment received diet + choline-RPC @ 45 g/d/cow (T2), fat-RPF 80 -30 +15 peripartum then 10 g/kg yield (T3), RPC RPF combination as above (T4) Inj. E-Care Se(R) ml i/m (Vit-E 500 mg Se 15 mg) -30, -15, 0, +15, +30 +45 (T5) along with blood samples for estimation levels insulin, IGF1, PGFM, estradiol (E2), progesterone (P4) cortisol. puerperal events parameters recorded months Result: fortnightly P4 concentration decreased, E2, PGFM cortisol gradually significantly (P less than 0.01) day thereafter P4, E2 remained or very low, decreased 45-60 postpartum, overall all groups. significant only higher values T3 T4 T2 T5 group. insulin IGF1 concentrations fluctuated insignificantly during phase lowest by also at some intervals highest both hormones followed uterine involution earlier control. first heat (days) (33.6±3.4), delayed (63.5±9.5) intermediate Group T4. conception rates 50.0, 75.0, 62.5, 75.0 87.5% T5, respectively, service period (96.3±14.6), (137.3±11.2), T1, (187 214 days). net returns over feed cost T2, T3, control Rs. +15898, +6150, +7165 +24060, respectively. findings reflected beneficial economic role alone Vit E profile improved
