Salient Achievements

  • Biul (Grewia optiva), Bamboo (Dendrocalamus hamiltonii), Khirk (Celtis australis), Tooni (Cedrela toona) and Kachnar (Bauhinia variegata) tree forages are suitable for incorporation up to 35% level in the whole concentrate diets of rabbits. Robinia (Robinia pseudoacacia) is not suitable for wool production in Angora rabbits.
  • The optimum protein requirement for Angora wool production in this region is 16% DCP i.e. about 20% CP in the ration. Groundnut cake, mustard cake, linseed cake and cottonseed cake are utilized equally well by the Angora rabbits. Feeding of mustard cake was found to be economical.
  • Rabbits for meat production can be raised economically on diets consisting of cereals and their byproducts supplemented with locally available tree leaves e.g. biul, mulberry (Morus alba) and bamboo.
  • Lantana toxin(s) are triterpenoids called lantadenes, the most important being lantadene A and C. In addition to the highly toxic taxon of lantana in the western sub Himalayan region, less toxic and nontoxic taxa devoid of toxic lantadenes have also been found.
  • HPLC methods have been developed for differential quantification of lantadenes up to nanogram levels.
  • Blood plasma markers for lantana induced hepatotoxicity are acid phosphatase and bilirubin.
  • The procedures for the extraction and HPLC quantification of the toxins in the Ageratum plant, chromenes namely precocene I and II, have been developed.
  • The leaves of eupatorium plant (Eupatorium adenophorum) are rich in CP. The supplementary and/or replacement value with mulberry, a tree leaf forage was studied and seems to be promising as an unconventional feed resource.
  • Histopathological and biochemical profile of the EBH affected animals in the region conforms to the disease profile in other parts of the world.
  • Guinea pig has been developed as a laboratory animal model for investigations on EBH and found to develop urinary bladder and alimentary canal tumors with bracken fern from enzootic and non-enzootic areas.
  • Ptaquiloside, the bracken carcinogen was found to be present in ferns other than bracken viz., Onychium, Pteris and Chelianthus, as well.
  • Onychium has been shown to cause chronic haematuria, urinary bladder and alimentary canal tumors in the exposed animals.
  • Investigations carried on diseases of livestock revealed that parasitic diseases, antinutritional factors in forages and infectious diseases viz. FMD, PPR, goat pox, HS, IBD, HPS and coccidiosis are major impediment to productivity of livestock and poultry in the region.
  • Investigations carried out on mortalities in wild animal revealed traumatic injuries were common in deer, leopard and peacock and parasitic diseases were common in civet cat, porcupine, jungle fowl, deer, ghoral, leopard and peacock.
