ANIMAL PHYSIOLOGY Research Achievements




  • First mithun calf(Mohan) born through embryo transfer technology (ETT) from cryopreserved embryo at the National Research Centre on Mithun on 12th May,2012
  • World’s first ever mithun calf (Bharat) through embryo transfer technology born at the National Research Centre on Mithun on 27th March,2012
  • Sensitive ELISA procedures for estimating growth hormone (GH), LH, estradiol-17β, total estrogen, prolactin, PGFM and oxytocin in mithun plasma have been developed and validated
  • A sensitive radiommunoassay procedure of estimating progesterone in unextracted mithun plasma has been developed and validated.

  • Secretion pattern of LH in growing mithun has been established
  • Twenty-four-hour rhythmicity of GH in adult mithun has been established
  • Twenty-four-hour secretion pattern of LH in female mithun has been established
  • Effect of exogenous GH-releasing hormone administration on pattern of LH secretion in growing mithun has been investigated
  • Diurnal changes in blood metabolites and their relation to plasma GH and feeding time in mithun heifer have been established
  • The relationship between plasma GH concentration and temperamantal behaviour in mithun has been established

  • Changes in plasma prolactin and oxytocin during milk letdown process in mithun cows have been established
  • Peripheral plasma concentration of estradiol-17β, progesterone, LH, GH and prolactin during estrous cycle especially during peri-estrous period in mithun has been established
  • Changes in the concentration of non-esterified fatty acid, glucose and α-amino nitrogen and their relationship with GH, estradiol-17β in cyclic mithun have been established
  • The possible causes of silent estrus in mithun has been defined
  • Different estrus/ovulation synchronization protocols in using prostaglandin, progesterone, estrogens, gonadotropins or their combination have been standardized for mithun
