    b. Project duration:  2012-2017 (XII five year plan)
    c. Brief highlights: Govt. of India sponsored ICAR project with an outlay of             Rs. 108.05 Lakhs for the period from April, 2009 to March, 2012 under XI Five Year Plan is being implemented at this Research Station. The same being continued under XII five year plan until March, 2017 with the financial outlay of Rs. 184.02 Lakhs.
    Objectives:
    To produce 50 breeding rams of a specific breed every year to cover about 2500 breedable ewes for enhancing quantity and quality of meat and/or wool production
    Capacity building in SAUs/ICAR institutes to produce above number of improved breeding rams.

RESEARCH ACHIEVEMENTS:

Highlights

  • Updation of flock status in home tract of Mandya sheep through systematic survey.
  • Distributed 233 elite breeding rams to 278 beneficiary farmers to cover their 8306 breedable ewes for enhancing quality and quantity meat production.
  • Strengthened the conservation of Mandya Sheep by  the establishment of Elite Mandya sheep seed flock as nucleus breeding unit at LRIC(S), Nagamangala, KVAFSU, Karnataka
  • Characterization & genetical studies on Mandya sheep was carried out.

Saleable technology developed

  • Formulation of feed for different age group of sheep to improve the growth      and production performance.
  • Formulation of feeding schedule for breeding rams, breeding ewes, pregnant ewes, lactating ewes, yearlings, hoggets (3-6 month), lambs (2-3 months) and young lambs (birth to 1 month).
  • Modern and scientific feed trays for different age group of sheep.
  • Status of Mandya sheep in its home tract area has been generated.
  • Adoption of different breeding technologies to improve the reproductive efficiency of Mandya Sheep and streamline of different breeding strategies.
  • Oestrus synchronization and Artificial Insemination in Mandya sheep.
  • Evaluation of Mandya ram Semen.
  • Generation of Growth performance of Mandya Sheep.
  • Generation of Average daily gain of Mandya Sheep.
  • Generation of Reproductive performance of Mandya Sheep.
  • Screening of Ecto and Endo parasite and their control measures.
  • Selection technology to bring about improvement in body weight.
  • Improved reproductive performance of ewe such as inter-lambing period, age at sexual maturity through artificial breeding technologies.
  • Mortality pattern in different seasons and their control measures.
  • Newer breeding techniques.
  • Silage making and dry fodder enrichment.
  • Agro forestry as a means of fodder supplement.

Technology commercialized

  • Breeding strategies for Sheep farming.
  • Silage making and dry fodder enrichment techniques for sheep farming.
  • Oestrus synchronization in Sheep.
  • Artificial insemination by means of fresh diluted semen of Mandya Sheep.
  • Mortality control measures.
