Estimations of blood plasma metabolites following melatonin implants treatment for initiation of ovarian cyclicity in true anestrus buffalo heifers

2010

Aim of the study was to investigate alterations in blood plasma metabolites following melatonin implants treatment for the induction of ovarian cyclicity in true anestrus buffalo heifers. True anestrus buffalo heifers (10) were equally divided into control and treatment groups. Each treatment group buffalo was inserted with 8 absorbable melatonin ear implants (16_19.8 mg melatonin/implant). Taking day 0 as day of implant insertion, blood samples were collected on _ 30, _15, +15, +30 days. Similar blood sampling schedule was followed for control group. Plasma samples were analyzed for progesterone, glucose, total proteins, albumin, urea, creatinine, lipid profile, AST, ALT, LDH, Ca and P. Melatonin implants were able to induce ovarian cyclicity in all the treatment group buffalo heifers. Following melatonin implants treatment, significant alterations were observed in plasma progesterone, plasma albumin and albumin/globulin (A/G) ratio in buffalo heifers; however majority of blood plasma metabolites remains unchanged. This suggested that melatonin implants treatment-induced modulations in blood plasma metabolites may not have a major role in initiation of ovarian cyclicity in true anestrus buffalo heifers.
